Solar panels are ‘wow’

I installed my solar panels 17 weeks ago today. 3 x 100 watt Biard panels on the roof.
Normally I’d recharge batteries with the gennie once every 3 days and it costs a tenner in petrol for the gennie each time.
So, 17 weeks is 119 days, that’s 40 times I’d have charged the batteries in that period, meaning, £400 of petrol.
However with having the panels, I’ve only had to charge the batteries using the gennie 5 times in that period, that’s £50. So I’ve saved £350 in petrol in that time.
The panels and all the associated bits cost just under £700, so in that 17 weeks I’ve already saved half the cost of them.
Wow is all I can say.
