My solar is what helps me.
What I don't use I export to the grid, and Scottish Power pay me for it. That payment is applied to my account, which pretty much wipes out my bill. To within a few pence I get my energy for free.
The repayment on the panels is £105 a month. Prior to the panels i was paying £130 a month on DD for gas and electricity, so straight away I'm 25 sheets better off.
On top of that I get the Feed in Tarrif paid to me every quarter, a couple of hundred sovs to spend on bike gear.
So, free energy and 7 or 8 hundred quids worth of cycle gear a year, and a 25 quid monthly bung for cake. We need a feeling smug avatar.
