You know that technology now makes it possible for everyone to enjoy free and clean electricity. Nowadays, electricity as it is generated today by fossil fuels, is very environmentally messy Fossil fuels give out harmful carbons that are destroying the ozone layer. This ozone erosion is causing unwanted climate changes that will be very consequential in the long run. Solar energy, on the other hand, is clean and renewable.
Electricity from solar energy is produced from sunrays and its are an unlimited resource. But electrical companies continue using expensive fuels that harm our environment. Adopting a solar energy lifestyle is very convenient.
You can buy your own solar panel availables online. The range in price goes from $1200 to over $7500. In Amazon you can buy a solar panel kit for $8000.
If you use quality materials to begin with, combined with some talent, you will have a quality product that may outlast the best that commercial setups have to offer. If you want a science project, yes, you will pay $3 per watt. If you go 1.5kW, I believe it can be as low as $1.7 per W:
Per 150W panel:
- 3/4in 2ft x 4ft plywood panel $20.
- 50ft tabbing wire and 10ft bus wire, $20.
- Solar cells $1100 for 500×2.5W unbroken monocrystaline cells ($0.77 per Watt), say use 60, or $132.
- 50ft tabbing wire and 10ft bus wire, $20.
- Clear silicone caulk/sealant $2.
- Screws, aluminium frame $10.
- Diodes $3 – Excludes time (call it 10-15 hours).
- Screws, aluminium frame $10.
- 3/4in 2ft x 4ft plywood panel $20.
- Clear plexiglass $20 (at low volume).
Total cost per panel is $248, so 1.65 per Watt. Possible to drop further at volume.
In the US, if you want to connect your panels to the grid your panels will need to have UL certification. But only if you want sell power.
In today’s world the DIY person can obtain everything that is needed to make your own solar power kit. There are several DIY books. They are all very good step by step guides that will show you how you can purchase from your local hardware store the materials needed to make your solar panels.
The materials should not cost more than about $200 or $250. This is well below the $8000 price for the Amazon.com system. Building a solar panel can be even be a great project for the whole family. Solar power is actually affordable for everyone with the right DIY manual. The videos they use are very informative and easy to follow along with.
