A solar panel cost depends on the amount of energy it could generate. I say to you! Even deliveries are not cheap. A solar panel with generating capacity of 120w sold to you in bargain price without shipping charges would cost around $650 dollars. Still you’ve spend a fortune for it even considering the saving it could generate. To make matters worse, since you do not have any idea how to install it. You will then have to hire a technician and spend another considerable amount of money for it.

Want a cheaper and equally good alternative?

Then build your own DIY solar panel. With the right instructional manual, a complete list of materials and contact detail of manufacturers, building solar energy panel would cost only $200 dollars of your salary. Yes it is true. You will be able to construct a 120w solar-panel for only $200 dollars. This saves you as much as $450 dollars enough to build another one to increase the generation of electricity. With $50 dollars still at hand, you can still buy a case of beer to celebrate your independence.

For first timers Earth 4 Energy provides very good instructional guide on how to construct these panels.
What is only required are the following:

• Detailed instructional manual (much better if given by an expert)
• A complete list of materials needed
• A classified list of materials from manufactures which only a few knows
• Oneself

Nearly everybody could make their own solar energy panels be it a female, male, middle-aged, old or young to power up a number of home appliances, heating the house or power even the entire house, if possible.

As you could see DIY solar panels aren’t costly as you thought it is. Moreover, using it could save you a lot of money in contrast to buying commercial made and having it installed. Don’t forget to look into my guide that contains over a 100 page of information, pictures and videos.

When you decide to build your own solar panels, you are contributing to the environment, your neighborhood and of course to your pocketbook or wallet.

The energy from the sun is free so using the energy from the sun to power your appliances will also be free. By building your own solar panels you will spend only about a tenth of what you would spend to buy one already made. Basically, a trip to the hardware store is all you need to get started.

Time wise, it will take you an hour to build one solar cell. You need to do this right or don’t do it at all. The commercially made cells are constructed from treated silicon and are very efficient and durable, but also very expensive. The cells you make yourself are simpler; you’ll need copper, a hot electric stove and patience.

Copper is quite expensive so it might be more economical to build your solar panels using pre-constructed cells. These can be purchased from online auction sites at a pretty good price. Using manufactured solar cells will save you a lot of time and frustration.

After all your solar cells are ready, you will need to start the process of building your solar energy panels. For this next step you will need to gather some tools, some plywood, glass or Plexiglas for enclosure, some all weather sealant and a soldering iron.

If you don’t want to do all the work yourself you can always ask your neighbors for help. Explain to them all the benefits of solar energy panels and how inexpensive it can be, especially if everyone chips in. Explain that it won’t take long to build enough solar cells and panels for everyone in the neighborhood. You can always offer some cold beers as an incentive!

By constructing and installing solar panels at your home, you can significantly reduce your monthly electric bill and at the same time set an example for other people in your neighborhood who are not so ecologically conscious. This is very easy project and possible for anybody to do, no matter what experience you have at DIY projects.

Ingenious solution shown on cansolair site served as an inspiration to build efficient “home-made” solar collector. Basically, it is incredibly simple and cheap solar panel for supplemental home heating, which heats the air directly.

The most interesting thing is the fact that solar panel is almost entirely constructed out of empty beer and soda aluminum cans!

Housing for solar collector is made of wood (plywood 15mm), while its front is made out of 3 mm (0.12 inches) Plexiglas / polycarbonate (you can use tempered glass as well). The back of the case set is made of rock wool (you can use Styrofoam) as insulation.

Solar absorber is made of beer / soda cans, and painted in matte-black paint resistant to high temperature. The upper part (cover) of cans is specifically designed to provide greater efficiency in heat exchange between the cans and the passing air.

When it is sunny, regardless of outside temperature, cans and inside air heat up very quickly. Small fan drives heated air back into the room.

Our solar system is not able to accumulate thermal energy it produces. When it’s sunny, the solar panel produces heat, but it is necessary to use it immediately for heating the air inside the house. If the sun does not shine, it is necessary to interrupt the supply of air in the solar collector, because otherwise the room will begin to cool down. This can be solved in a simple way – by installing the valve, which will reduce the heat loss to a minimum.

Small differential thermostat (snap disk) controls the fan. This thermostat can be bought in better-equipped electronic component stores. The unit has two sensors. One placed inside the top opening for warm air, the other inside the lower opening for the supply of cold air in the solar collector.

If you set the temperatures carefully, the solar collector can produce an average of 2 kW of energy for home heating. This generally depends on how much sun do you have during the day.

Dress rehearsal of solar collector was carried out in the backyard before installing the system on the house. It was a sunny winter day, no clouds. A small cooler extracted from a faulty power supply of PC was used as a fan. After 10 minutes in the sun, solar collector produced hot air with temperatures of 70 ° C!

The test results have encouraged us to install solar heater on the house as soon as possible.

After completing installation of solar panel, the outside temperature was -3 ° C, and from the solar collector was coming out 3 m3/min (3 cubic meters per minute) of heated air. In the home version we used more powerful fan than for the test. Heated air temperature went up to +72 ° C. Temperature was measured by digital thermometer. Small anemometer measured the speed of the air circulated through the solar collector. To calculate the heating power of our solar panel, we took the air flow, and average air temperature at the exit from the unit.

Calculated power that the solar panel produced, was approximately 1950 W (watts) which is almost 3 HP (3 horsepower)!!!

CONCLUSION: Considering that the results were quite satisfactory, we can conclude that this solar panel is definitely worth making. The collector, at the very least, costs under 150$ and can be used for additional heating of our home, and it is up to you to calculate and figure out how much savings you can achieve.

The increase in popularity of the solar DIY kits and wind turbines for homes has brought about a radical change in the way that most people view this technology. For many years, it was ludicrously expensive to install and would take years before you starting to make your initial investment back. There was no such thing as cheap solar panels, but that has all changed. Do it yourself solar panels are not just easy to manufacture in your back yard, but will cost a fraction of the price of the already made models.

Even without any experience in building home solar systems, just about anyone can follow the novice video instructions and build an 80watt panel in their own garage. Just by popping down to the local hardware store, you’ll find everything you need. The solar panels cost no more than $200 to manufacture and because you built it, you know how to fix it. A roof solar panel can be used to run a refrigerator, or a television or even a washing machine. At a cost of just a few hundred dollars, you can turn these cheap solar panels into a lucrative income by building them and maintaining them for people you know.

You don’t have to stop there, household wind turbines are just as easy to manufacture and at half the cost of a solar panel, you can harvest a breeze into extra power for your home. Wind generators for sale are usually of the marine kind and do an excellent job, but due to the cost involved, they are not often used as wind turbines for homes. The home wind generator can be built in hours and can be a great addition to your alternative energy plan.

With your very own solar wind generator system, you can save money, earn money and in the event that there is a power cut, you don’t have to miss that vital sports game. In fact, you can still watch and have a cold beer while the neighbours watch on jealously and all this while doing your bit for the planet.
