Solar Panel Novice

lucylou32

I’ve read thru the Martin Lewis recommendations and did the calculator thing, but the results of that, look miles away from the quote I’ve received. I just can’t compare the 2 to see if they’re a good idea for us.. 

can anyone help, see if I’ve done it right…

our postcode is TN9 2HH. We have room for 12 panels, I’m home all day, we’re looking at having 2x batteries 3.2 storage. Roof is 44 pitch, 17 degrees from south. 4.68kWp size, shade factor 1, estimated SAP production 5,208.84. Price includes bird protection enviroguard and scaffolding. £10k. Total. The quote says we should break even in 8-10yrs. But the calculated here says we’ll only save £400 on energy bills each year, so that’s over 20 yrs to break even ! 

Thanks for any help or guidance offered.

Go with an estimate that you will use half of what you generate (some will go into the batteries and out again and you'll lose 20% of it but let's not complicate things)

Calculate how much you will save from not buying electricity, using half of predicted output and the cost in pence/kWh you are being charged for electricity.

The other half of your solar output will be exported. Calculate in p/kWh how much you'll be paid for it (you can look up SEG payments and decide which company to go with)

Add the 2 together and you have a fairly rough idea of how much you'll save in a year.
