Panel installers damaged roof!!

[binky]

But the "free electricity" is only of use if you understand how it works.

I removed and reistalled a set of panels on a house so the roof good be replaced. Talking to the tennants they had no idea what the solar panels could be doing for them and where putting appliances on overnight to get the cheapr off-peak tariff   :shakehead

So what we do, is make sure water heating, and all the big appliances like washing machine, dishwasher and tumble dryer are only ever done one at a time in the middle of the day.  And then we have a solar PV diverter that sends excess power to the immersion heater.  Just by doing this we self use 95% of what is generated.  This will reduce your electricity bill.

But if you don't know this, and are out at work all day and use the big appliances in the evening when you are in, then you won't be self using much of it and won't be saving much money.

 95% that's good going!
