Build Your Own Solar Panel

A study released earlier this year by the Agricultural and Food Policy Center at Texas A&M found that higher energy costs are the driving force behind changes in the agricultural industry. As Jeff Broin, CEO of leading ethanol producer POET, points out in an interview with blog Earth2Tech, the answers we need can be found with a little simple arithmetic. A study from the Agricultural and Food Policy Center at Texas A&M said, “The underlying force driving changes in the agricultural industry, along with the economy as a whole, is overall higher energy costs, evidenced by $100 per barrel oil.” Just do the math. A semi can haul 4,200 boxes of corn flakes at a time, and with 10 ounces of corn in each box, that’s a total of 46.9 bushels of corn. At a $6 bushel, the corn in all 4,200 boxes has a value of $281.40. To haul those boxes 1,500 miles, however, would cost $881.25 with diesel priced at $4.70 per gallon. That means it takes 21 cents of diesel per box to get it to the store, yet the value of corn in that box is less than seven cents. What do you think is the real driver of higher food prices? [Ed. note: The quote Jeff Broin uses can be found on page 3 of the study. A free copy is available by download here , or by clicking the direct link in the first sentence of this post.] The rest of Broin’s interview is pretty interesting as well. He talks about his company’s future cellulosic plans as well as ethanol’s role in politics, among other things.

A local energy company in Clearwater Florida is proposing to raise its energy costs…again. Over the last year this company has raised its rates by around thirty percent and residents are starting to worry that, with the economy tanking and layoffs happening everywhere, that they won’t be able to afford to keep their electricity on anymore. And while Florida is known for being warm all year round, who wants to go camping in the winter, especially when there is no end in site to the camping? It only takes a couple of days before the idea of a hot shower becomes so beautiful that you consider bribing your friends and family to let you live with them instead of trying to keep your own—just so that you can feel warm water on your skin again.

In a time when energy costs are increasing (ironic considering the drop in fuel costs), it becomes even more important to cut down on power usage. The following list presents Clearwater residents with some tried and true ways to cut down on their energy bills and some more…creative ideas as well.

1. Put blankets over your windows and outside access doors. Sure it makes you look like a hillbilly, but when you cover your windows, you reduce the amount of heat loss that occurs. Windows and outside access doors are like sucking vortexes for heat. The thicker their coverings, the warmer your house will stay—and you won’t have to keep kicking the heater up a notch.

2. Unplug whatever you are not using. Sure it’s a pain in the butt to have to plug your television set back in, but it has been proven that unplugging appliances and machines when they are not in use can do a lot more to cut down on your electric bill than simply turning them off.

3. Learn to love hats and shoes. Most of your body heat is lost through your head and your feet. If you keep them covered, you won’t be as tempted to kick up the heat in your home!

4. Grill—even in winter! Using your grill or barbecue cuts down on the amount of power you need to make dinner and can lower your bill. No it won’t be fun to stand outside if it is cold, but grilling or barbecuing even just a few times a week can spell the difference between being able to afford your electric bill and….not.

5. Join some clubs or other social organizations that require you to leave the house. The less time you spend at home, the less energy you will use. Join a knitting group or a book club—something that doesn’t require money to join or a lot of driving around. Plus, you’ll make friends and have fun!

These are just five ways that you can cut down on your energy costs. You already know about energy saving light bulbs and the like. Now it is time to get creative and figure out what else you can do to reduce your energy consumption!

Without a clean interactive “tool” for control of global temperatures, we are relying upon the unstable nature of our environment to continue to mend itself, regardless of our abusive actions. In addition to our own actions, history has shown that nature often has global extinction events. There are many natural generators of greenhouse gases.

If the methane permafrost melts, billions of people may die from reduced global agricultural harvests, aggravated by unstable plant pathogens caused from reduced plant and animal diversity. Currently over 6 million people die of starvation annually; this number will only increase. Those people in positions of influence who do not act now to save those peoples’ lives, are directly responsible for their deaths.

Oil Company Revenues – A necessary transition

Oil is a fixed commodity. The revenue generated by oil can be extended from a 100 year supply to a 1,000 year (or more) supply; if it is used to make products instead of fuel. Of course with reduced production, the price per barrel would increase, but delivery costs are reduced because supertanker ships need not be built. So the cost of plastics, antifreeze, and lubricants would increase due to the restricted supply. Cost per barrel of oil being a balance between shipping cost savings and supply/demand of the products produced using fossil fuel. Regardless, this seems an attractive trade-off for a green economy. Especially when the cost of electric utilities plummet and the cost of hydrogen correspondingly plummets. As for comparative costs:

• How much does it cost to build AND maintain a supertanker?
• How much does it cost to continually develop new oil resources?
• How much does bad press cost?

Additionally, by having the Oil Companies fund a Global Energy System, the free and multimillion year supply of solar energy provides incomes that can not be generated by fossil fuels. For instance, even with oil at $50 a barrel, it was not economically feasible to develop the Northern parts of Canada, the Sahara, or event the US Southwest. The low energy density of oil coupled with shipping costs has made living in remote locations impractical. Because of the broadly distributed nature of space-based solar collectors, the cost of fuel anyplace in the world is virtually the same. New technology based populations can be developed in the most remote places on Earth.

The Earth can easily support 100 billion people if there is sufficient energy resources. So Oil Companies would be selling power to 100 billion people, instead of the current 6.7 billion people. There are other significant sources of related revenue as well. That’s an estimated increase of 15 times the current energy usage; 17 times the current net revenues (more energy users, higher cost per barrel of oil, lower oil infrastructure costs, …).

Ecologically Sound Solution

The problems with most solutions proposed for controlling Global Warming are:

* the expense and the requirement for on-going funding
* high risk of damage to the environment
* ineffective nature of proposal
* narrow focus of proposal, not allowing for collateral and beneficial enterprise to develop
* foreseeable health hazards
* inability to attain multilateral support of all nations

We must initiate a comprehensive process that not only addresses the symptoms of Global Warming, but also addresses the core causes; including those causes that are “naturally” produced.

Space-based Solar Concentration Facilities

Establish a space based solar energy collection and conversion system to generate an excess of abundant clean energy for the world. Real Estate is free in space and is unencumbered by political boundaries. This system would minimize (if not eliminate) the need for fossil fuels by using solar energy to generate cheap hydrogen to power fuel cells and engines. Petroleum would be produced for plastics and other products, extending petroleum industry survival for several hundred years. Providing cheap electrical energy to the world allows for hydrogen and water to be extracted locally anywhere on the planet:

Collateral Business Developments

Use the sale of power to fund the Space Elevator, thus reducing the cost of shipping and transportation to/from orbit to 10% of current costs; thus making access to space available to virtually anyone. A side benefit will be the many start-up industries that capitalize on the mass production of carbon nanotubes.

Vehicle strengths can increase hundreds of times over present vehicles while weighing significantly less. Vehicles can potentially impact at up to 20 mph without any significant damage. Mountain climbing ropes can be reduced in size to the size of a string and be stronger than present ropes; allowing for lighter pack loads and longer ropes. A 1200 pound Harley Davidson motorcycle could be made to weigh less than 200 pounds; while being considerably stronger and more powerful. Commercial airliners could have ballistic parachutes which automatically deploy to save the lives of passengers. Buildings can be produced which can withstand the strongest of earthquakes. Skyscrapers a thousand stories tall. Diamond cable saws capable of cutting up asteroids for mining. Earth boring machine cutting heads that are much stronger, more efficient, lighter, and more versatile. Allowing for subterranean habitat development; here on Earth, the Moon, Mars, large asteroids, and other planets and their moons. A woven sheet of nanotubes and bonding agent would line the caverns to provide air tight living spaces. Orbiting and transiting space habitat structures large enough to hold thousands of inhabitants including their systems for being self-sufficient. Computer and cell phone cases that are virtually indestructible; yet lighter than anything we currently have:

Systematically cleanup orbiting space debris and force nations to be accountable for contributing to space debris: (provided in the first link)

Building a global Weather Control System

Establish a global Weather Control System (WCS) to Reverse and provide active control over Global Warming and rebuild the glaciers, ensure the methane permafrost remains intact, control the ash laden winds in the vicinity of erupting volcanoes, manage predictable rainfall for agriculture, control wind direction and rainfall for forest fires, eliminate severe weather and the resulting damage, promote responsible ecological controls, …

The world revenue spent and lost outside of intent because of weather phenomena approaches 1 Trillion dollars annually. The total weather control system is a fraction of this cost and can be funded through the sale of power and fractional royalties from space based industry developments.

Looking to the Future

Through a series of technological processes we can quickly transition from a species dependent upon our natural environment, to a species that becomes a responsible part of our environment, and this system provides the means to support the ever growing human populations. While taking an active part in preserving our ecology and ensuring our grandchildren will experience the richly diverse life we presently enjoy; and perhaps a world with greater diversity and wonders not yet imagined.

In 1776 there were less than 700 million people worldwide. The second of two people living to be 100 years old would have seen 1976 and a population of over 3,000 million (3 billion) people; a growth of 4.3 times as many people in 2 peoples lifetimes. Presently, there are over 6.7 billion people; the world population has doubled in less than 30 years. We can fully expect there to be at least 35 billion people by 2076. Medicine and food supply technologies improve, people naturally live longer, what will life be like unless we provide a habitat, interesting employment, and business opportunities?

Currently, China uses people with shovels and rakes to process their sewage, because labor is so cheap. What will our grandchild’s life be like if we do not push our horizons above that of the Earth?

Within just 50 years, it is expected that between 1/3 and 1/2 of all known species of plants and animals will verge upon extinction due to salt water encroachment of coastal wetlands. How do we plan to help maintain our ecological diversity to provide natural food chain stability? Already, corn and potato crops are documented to be at risk worldwide. Over 6 million people currently starve annually; it can be shown that almost 30 million people will starve annually by 2076 unless we act diligently in the present.

We must have a comprehensive system that provides for the needs of our small world. Allowing us to have more, not less. Allowing our population to grow; responsibly.

Initiate a comprehensive self-funded system to actively “Reverse” Global Warming, provide for a diverse ecology, provide for economic growth, provide abundant clean power, control extreme weather, and provide for our ever growing world population.

Rising production costs and fierce competition is resulting in manufacturing companies looking at all aspects of savings, especially energy savings.

Spray nozzles of the right specification can lead to significant savings in both energy and raw materials.

One of the overlooked areas is the use of the correct spray nozzle. Whilst frequently ignored in the manufacturing process, it is often this item of equipment that is the most important. Header tanks, pumps sophisticated controls, pipe work are all immaterial if the spray nozzle “at the sharp end” is not delivering the right amount of fluid (flow rate) at the correct spray angle and with the right spray pattern. This can lead to excessive wear on the pumps and ancillary equipment resulting in higher energy consumption and related costs.

The phrase it sprays, is often used, but how effectively is often not considered.

In addition to these more obvious savings there are a many “hidden” savings to be made.
Expensive down time and failed equipment could be contributed to poor nozzle performance.
Production lines designed to operate continuously are expensive items if shut down owing to badly performing spray nozzles and this failure could affect the total production plant with the resulting unsuccessful distribution to customers, which in turn may affect their production.

All this from the wrong or poor performing spray nozzle!!

The correct spray configuration is essential to maximise the spraying operation and continuous spray nozzle development will lead to greater beneficial savings.

In addition, the wrong or worn out spray nozzle will eventually lead to poor finished products and possible rejection of expensive products. This could result in extra production to make good these shortfalls, with the resulting increase in energy costs. All this will reduce profit margins.

Initial investment will be required to introduce the correct nozzle, but payback can probably be counted in months and in some case weeks.

As an ongoing maintenance program, substantial savings will be made by regular inspection and maintenance of the spray operation and possible replacement when nozzles become worn, through blockages, corrosion, wear and accidental damage
Regular maintenance of the spray nozzles must be undertaken to ensure the nozzles have optimum spray performance.
All nozzle configurations should be analysed on a regular basis to ensure that the spray pattern, flow and operating pressure cannot be improved upon, possibly with new nozzle technology, or the fact that the application process has not changed. The latter being the case then a new specification should be sought.

As well as energy savings, raw material savings must also be taken into consideration and it is feasible to experience water reduction of up to 40% in certain industries and spray nozzle applications.
Also to be taken into consideration must be the application where the spray fluid is not water, but more expensive chemicals or fluids. With correct nozzle design even greater savings may be achieved.
Energy savings can be made in pump operation and it some case it is possible to reduce the number of pressure pumps, thereby saving considerable operating costs and associated maintenance cost.

To summarise, energy savings, raw material savings and a reduction in the wear and tear of other equipment can all be experienced if the correct spray nozzle is specified.

The specification must include nozzle material, spray angle, spray pattern, flow and pressure. With all these set correctly a regular maintenance programme should be undertaken. With the correct specification and maintenance schedule then energy and raw material savings can be expected.

Although it is much less expensive to initially get hooked into the local electric company’s grid than it is to set up and hook into wind turbines, in the long run one saves money by utilizing the wind for one’s energy needs while also becoming more independent. Not receiving an electric bill while enjoying the advantages of the modern electrically-driven lifestyle is a wondrous feeling.

Electric bills and fuel bills are rising steadily but the cost of wind turbine energy is zero, and the cost of installing and hooking up a turbine is steadily coming down as demand rises and more commercial success is realized by various companies producing the turbines and researching technologies to make them ever more efficient.

In addition, people are moving away from the traditional electric grids and the fossil fuels for personal reasons including desire for greater independence, the desire to live remotely or rurally without having to go primitive, political concerns such as fears of terrorist strikes on oil fields or power grids, or concerns about the environment.

Again, this motivation to get away from the traditional energy sources is the same one that causes people to seek the power of the wind for their energy, giving more business opportunities to profit from wind turbine production and maintenance, which drives their costs down for the consumers.

In nearly thirty states at the time of this writing, homeowners who remain on the grid but who still choose to use wind energy (or other alternative forms) are eligible for rebates or tax breaks from the state governments that end up paying for as much as 50% of their total green energy systems costs.

In addition, there are 35 states at the time of this writing where these homeowners are allowed to sell their excess energy back to the power company under what are called net metering laws. The rates that they are being paid by the local power companies for this energy are standard retail rates in other words, the homeowners are actually profiting from their own energy production.

Some federal lawmakers are pushing to get the federal government to mandate these tax breaks and other wind power incentives in all 50 states. Japan and Germany already have national incentive programs in place. However, A lot of this is handled regionally by state law. There wouldn’t really be a role for the federal government, the Energy Department’s Craig Stevens says.

And as might be imagined, there are power companies who feel that it’s unfair that they should have to pay retail rates to private individuals. We should [only have to] pay you the wholesale rate for … your electricity, according to Bruce Bowen, Pacific Gas & Electric’s director of regulatory policy.

However, the companies seem to be more worried about losing short term profits than about the benefits, especially in the long run, of the increased use of wind turbines or wind farms. Head of the Center for Energy Efficiency and Renewable Technologies of California V. John White points out, It’s quality power that strengthens the grid.

Everyone finds it ideal to have homemade solar panels installed even before your dream house is ready, it is most efficient and cost effective to build your own homemade solar panels rather than buying them, this way you could be saving thousands that you can use for other home improvements. The best part of it all is that you can save on your energy bills for a lifetime and don’t worry — solar panels aren’t that hard to build, there are several great guides that give you step-by-step instructions to make a fully functional solar power system.

Even before starting to make your solar panels you need a little research and find the most profitable components for your DIY project. In fact we’ve done all the research for you and came up with a few conclusions. You need two basic things to get started, a solid DIY guide and all the necessary components. You won’t be spending more than two hundred dollars since all the parts are quite cheap in most hardware shops.

You’ll need to make up a list of all the components you need and carefully research for each one of them to find the best price. We’ve spend in excess one month to find all the parts that are required to install a fully functional solar panel. New solar cells can be costly, depending where you’re buying them from. There are several retailers that are selling used solar cells for a quarter of the normal price. (You need to be careful some of these cells might be damaged). Anyway there’s no need to worry because a solid DIY guide will help you not only build solar panels but give you step by step instructions on how to get all the necessary parts at the cheapest price.

Depending on how much energy you will need, you might have to build more than one solar panel and obviously the price will go up a little. Another thing to know is that solar cells are fragile even if they don’t seem to be. They can easily be damaged so handle them carefully. A solid homemade solar panel plan should contain all the information you need to build and use a solar power system and not only that but it must have an online tech support team just in case you’re having any difficulties.

Home made solar panels are quite easy to make these days considering the low cost of the components. They’re basically the heart of your solar power system that can drastically reduce the cost of electricity. The number of people that install solar panels in their houses is growing pretty fast due to these hard economical times and I am sure you’re looking to build such a system that can reduce your energy bills by 80% or even more.

The solar panels basically transform the solar energy into electricity. Buying ready made solar panels can be quite expensive and there’s a low return on investment. The cheapest solar panels are sold for $2000 or even more and that is why you would be better learning how to build your own solar panel and save hundreds that you can use for other home improvements.

We’re now building our fifth 200 W solar panel that will supply enough energy to light up two bedrooms. Read on to get an overview of how simple it is to build your own homemade solar power supply and what exactly you will need to get it installed properly.

For everybody that doesn’t know the main parts you need to build a solar panel are: plywood, copper, glass, wire, solder, silicone and UV protector and of course the solar cells or photovoltaic cells that basically capture the solar energ and transform it into green electricity. Solar cells are nearly half of your investment, they can be found at any solar parts shop or they can be order online at the lowest cost. Apart from all the component you’ll also need a solid guide in order to start your DIY project and accomplish it successfully without getting any headaches.

We personally followed the Earth 4 Energy guide simply because it’s a real blueprint that can teach even a DIY novice where to get the cheapest components and how to make a homemade solar panel with ease.

Nowadays, seeing the dearth in the earth’s reserved energy resources, different organizations are trying to utilize the renewable energy resources like solar energy, tidal energy, wind energy etc. for different purposes. Among them Solar Energy is the most abundant and is gaining more popularity. The decline in the availability of fossil fuels and hike in the cost of electricity have paved the way for solar energy to become the alternative source of energy for all of us.

Solar heaters: more feasible for home

People are now trying to build homemade solar heater so that they get relief from the shortage of energy. New innovations are coming up for running industries and households and out of all innovations for utilizing the energy of the sun; solar heaters are the best option for household activities. Besides, converting solar energy by using solar heater takes less designs and processing in comparison to other application of solar energy.

Working of solar heaters

When the molecules are excited, their vibration causes the evolution of heat as a by-product and to stabilize themselves they have to release this energy. This happens when the sunlight falls on the highly thermal conductive substance and excites them. This movement and heat is transferred from one material to other causing an incessant flow of heat.

Application of solar heaters

Water heaters and air heaters are the best application of solar heaters used for household purpose. All varieties of solar heaters have solar panels. The mechanism is very simple, entrapment of solar energy into photovoltaic cells and converting it to electrical and heat energy.

Reasons for building a solar heater at home

Though you can get one in the market, but building one yourself at home will give you satisfaction and you can design it according to your wish. Secondly, initial cost is lessened because you can use recyclable materials like aluminum cans, which are easily available at home for making solar panels.

It took me a few months before I got my head around this whole “solar power for homes” idea.

I had researched all about energy effecient homes on the net and spoken to a few of my builder friends. The more I learned the more convinced I became that building and installing solar panels for your home was the way to go. It’s not only that you can reduce your energy bills but I also liked the fact that you are helping the environment and conserving this planet of ours, by reducing your carbon footprint.  Now, I don’t know about you, but this really got me interested.

I knew folks on our road that had had solar energy panels installed in their homes.  Like me, the solar energy advantages of low fuel bills had peaked their interest. Only problem was that they had forked out thousands of dollars to get their home solar system.

I didn’t really have that sort of money.  So, I found out all I could about home solar power systems. I bought lots of guides and ebooks and tried a few things but nothing was that simple. It wasn’t easy to build something like a home solar panel if you had never built one before.

And then, a few months ago, I came across a guide that showed step-by-step how you could build your own solar energy panel and work towards turning your home into an eco friendly house.

I hope the video above, showing you how to make solar panels for your home, will make you as eager to get started as I was.  Seeing someone else making their own residential solar power and making it look “doable” gave me an itch to get started.

Click here to visit the website for this DIY green energy guide and find out all the benefits of making your own solar energy.

My wife loves the energy effecient home we have now.   Trust me, DIY solar power is the way to go. I hope you are itching to get started too. Good luck!

I looked everywhere online for guides to show me how to build solar panels in order to create my own solar energy home. I looked for months and I found a lot of rubbish.  And then I found a gem of a little DIY guide to making your own solar energy.

Did you know that you can build your own solar energy for less than $200?

It’s kinda amazing isn’t it? Did you know that by building your own solar panels you can save $10,000s off the retail price of buying them?

And did you also know that the average cost of getting solar energy for your home comes out to about $27,000?

Did you know that you can build your own solar panels for a fraction of the cost of new retail solar panels?

Imagine cutting down on fuel bills and energy costs.

Imagine doing your bit to save the environment. Yeah, it’s pretty mind boggling stuff.

Imagine how excited I was to finally have found something that actually worked.

Of course, not “anyone” can build a proper home solar panel, especially if they do not have the relevant experience. But, don’t worry about that because there is a step by step guide that shows you EACH STEP you need to build your own home solar panel system.

When I bought this new Solar Energy DIY guide, I found, much to my delight, that as well as the guide there were 6 videos to watch. Sometimes, its easier to watch a demonstration as a picture is better than a thousand words.
