What is the cheapest way to install a solar panel large enough to power a semi-detached house? Answered

I am looking to buy a solar panel, and need some advice on how to find a cheap panel to produce enough electricity to power my full house, for years to come.


How many watts will this need, at the most at any given time? That will determine to a large degree the cost of your project.

if you invest, $30,000 you can power your house

...when the sun is shining....and in the summer....here in the UK insolation in the winter is pretty pitiful.

It's not cheap. I have an 11,000 kW system that was nearly 80 g's.

You have to try and find out about incentives offered by wherever you live or find a contractor that will do the installation and help you obtain whatever rebates are available.

11 MEGA watts for only 80g's ! That's incredibly cheap ..... ;-)

There's no such thing as a free lunch. PV cells are expensive. Enough to work off grid costs  a lot of money. The cheapest way to use solar is water heating.
