Hi Petunia. We have had solar panels since early 2012, and we recouped the outlay, much more quickly than forecast.
As to the batteries, I don't know the cost of them, but have been told they are expensive. DH thinks we wouldn't recover the cost of installing those.
We are 80 and 77!! Mmmm
As to having solar panels, I would have them again, although when we got ours, the Feed in Tariff was very good, but has now changed, but the installation costs are now lower I believe.
DH reckons that with the income from them, we receive more than the outgoings for Gas and Electricity , so are in profit.
