Warnings & Dangers of DIY Solar Panels
Also, if you should be contemplating making your own personal solar panels to cut the expense of your solar energy house, please know about these:
– In the US, you’ll NOT be allowed to get in touch your house made solar panels to the grid. If you prefer your solar energy house to link to the grid, you have to use solar panels with UL certification. Many countries have similar regulations.
– Commercially manufactured solar panels have 25 year performance guarantees. DIY solar panels don’t have any guarantees and will most likely last just a few years at best.
– With any home made solar panel there is a danger of fire from low quality soldering. If your DIY solar panel ignited and triggered fire damage to your house, your insurance company might be considered a little reluctant to cover out for a fire caused by a solar panel that did not have UL certification.
– And the ultimate nail in the coffin of a home 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 prefer solar panels for your solar energy house and want a method that’s safe, reliable, qualifies for rebates and will really cut your electricity bills, forget DIY. DIY can be a great introduction to understanding what it means to really have a solar energy house, but it’s not a feasible option to factory made solar panels.
Produce a Solar Panel as a Science or DIY Project
However, if you wish to make your own personal solar panel as a science project, this is fun, satisfying and very rewarding. On completion you will even have a solar panel you are able to show off to friends and family and something you could utilize to offer light for a lawn, shed or outbuilding.
If you wish to make a solar panel as a science project, consider buying among the “how too make solar panels” guides. Some of these are great and do an excellent job of showing you (they have some great videos) what direction to go, how to complete it and when to do. Yes, helpful information will add $40 – $50 to the fee, but that may be money perfectly spent, just don’t fall for the marketing hype!
If you will want solar energy home and to reduce your electricity bills, forget the DIY route. But, although you won’t spend less or lower your electricity bill, making a solar panel included in a science project must be very satisfying and educational. If you don’t want to invest the $40 – $50 for among the DIY solar panel guides, there will be a lot of informative data on the Internet. I wish every success with your Solar Energy House.
