Anywhere doing it in town, walk in preferably

Hello Im just asking genuine guidance if anyone has solar installed in their house and would appreciate knowing;

Has it been of benefit with our cloudy sky most of the year

How efficient is it for you, does it cover 100% of your needs

Has it had any faults and what was the after sales service like if so

What is your payback period

How do you clean the panels if on the roof.

Any other comments related to solar.

Thanks in advance.
