Cost of Factory Made 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 are considering making your own personal solar panels to cut the price of your solar energy house, please be aware of the next:
– In the US, you’ll NOT be allowed to connect your house made solar panels to the grid. If you would like your solar energy house to link to the grid, you need to use solar panels with UL certification. Many countries have similar regulations.
– Commercially manufactured solar panels include 25 year performance guarantees. DIY solar panels don’t have any guarantees and will most likely last just a couple of years at best.
– With any home made solar panel there’s a risk of fire from low quality soldering. If your DIY solar panel ignited and triggered fire damage to your house, your insurance company might be a little reluctant to cover out for a fire the result of a solar panel that did not have UL certification.
– And the ultimate 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 would like solar panels for the solar energy house and want a method that’s safe, reliable, qualifies for rebates and will really cut your electricity bills, forget DIY. Bateria seca DIY could be a great introduction to understanding what it indicates to really have a solar energy house, but it’s not a viable option to factory made solar panels.
