How to build solar cell at home?

Question

i want to build my solar cell for energy at home

Answer 1

You can buy solar panel kits from places like B&Q now. They are about £2000 for a modest size kit. Any excess power you generate may be sold back to the national grid.

The problem is that these panels can take around 20 years to recoup the cost on your bills, and the average lifespan of a solar panel is about............. 20 years!

Answer 2

you can't reasonably build a photovoltaic cell on your own.  

you could build a solar thermal collector which would heat water for home use. Unfortunately hotwater is probably one of the most minor use of energy in the home.
