It you’re keen to create your personal Solar Energy House you may well have considered DIY solar panels. Well, while I applaud your desire to have a solar energy house, i’d like to warn you that you will not conserve money by making your personal solar panels. Lets look at why.
Cost of a DIY Solar Panel
Lets ignore the price of your time. This is a list of the materials required:
– Clear plexiglass or low iron solar glass 2ft x 4ft x 1/4in $34 or maybe more
– 3/4in 2ft x 4ft plywood panel $23

Cost of Factory Made Panels
Should you choose an everyday search on the Internet, most solar panels workout at $5 – $7.50 per watt. But we ferreted around and found a 120watt panel for $358 retail, equivalent to $2.98 per watt. Additionally, there are several wholesalers willing to offer direct to people, and minimum order quantities is as low as two panels. We found a 225watt solar panel wholesale for $549 (min order 2 panels), equivalent to $2.44 per watt.
Warnings & Dangers of DIY Solar Panels
Also, if you should be thinking about making your personal solar panels to cut the price of your solar energy house, please be aware of the following:
– In the US, you’ll NOT be allowed to get in touch your home made solar panels to the grid. If you like your solar energy house to link to the grid, Baterias solares you have to use solar panels with UL certification. Many countries have similar regulations.
– Commercially manufactured solar panels come with 25 year performance guarantees. DIY solar panels don’t have any guarantees and will likely last just many years at best.
– With any home made solar panel there’s a danger of fire from low quality soldering. If your DIY solar panel ignited and resulted in fire damage to your house, your insurance company might be considered a little reluctant to cover out for a fire the effect of a solar panel that did not need UL certification.
– And the last nail in the coffin of a property made solar energy house: in the US, home made solar panels will NOT qualify for the significant rebates and tax credits which are available.
If you like solar panels for the solar energy house and want a system that’s safe, reliable, qualifies for rebates and will really cut your electricity bills, forget DIY. DIY could be a great introduction to understanding what it indicates to have a solar energy house, but it’s not a viable alternative to factory made solar panels.
