100W DIY Solar Panel Kit 40pcs 5×5 125x125mm Polycrystalline Poly Solar Cell Tab Wire Bus Wire Flux Pen for DIY 12V Solar Panel

Make your own solar panel … I made a 80 watt panel from scratch 6 years ago (before you could buy kits), it was lots of run and i learnt a lot about solar power in the process.

I will post a blog on how to do this sometime in the future, but in the interim here are some instructions.

Product Description

  1. High efficiency up to 16.4%.

2. Proven long term mechanical stability of silicon.

3. Make of highly purified poly silicon.

4. Two bus bars for reduced series resistance and improved module and cell efficiency.

5. Blue anti-reflecting coating ensures improved light absorption and increased efficiency.

6. Acid texturization offers a uniform appearance and virtually invisible crystal structure.

7. Excellent low light behavior for improved energy yield.

8. All the solar cell will be sorted and tested before delivery.

9. We test solar cell by professional machine, the most precise testing facility for you
