    We’ve a south-facing roof, with no shade.

    1920s semi, two adults, two kids. Eight 300W panels, with a SolarEdge inverter for individual panel monitoring. No storage, but it’s battery storage-ready.

    Is solar a no brainer, or did I make an expensive mistake last night?

    It was a no brainer for me.

    High electricity consumption due to commercial requirements.

    3 phase power supply and lots of roof space, so put a 12kw system in.

    Worse case it should pay for itself in 7 years.

    A much better return than leaving £12k in the bank.

    Can I ask you how much you paid?

    It depends how much you paid, and how.
    Is the contract going to affect a future sale, or are you buying outright?

    It mainly depends how much you paid, assuming your supplier meets all the criteria for you getting the FIT payment. But there’s a possible catch with a 1920s semi, depending how many insulation upgrades it has – to get the 4p/kWh FIT payment, you need to have an Energy Performance Certificate showing that the house meets level D or better, see here

    We’re paying just under £7k for a 2.4kW system.

    It’s on finance, with a reasonable low interest rate and the option of overpaying a lump each year. The annual FIT ‘cheque’ will go to overpaying.

    I knew that there was a reason I asked on here! I don’t think the house a D or better 8 years ago when we bought it, but we’ve made some improvements since.

    That’s quite expensive. Have you had any other quotes? Those Solar edge inverter’s are expensive and “nice to have” but don’t really justify their extra cost. I was advised to just get a normal inverter.

    My panels were about £200 each and the inverters were about £500.

    I got 2 quotes and both broke down the numbers to show equipment costs and installation etc separate.

    The installer normally has a “tame” EPC assessor. 😉

    We also have 3 phase and loads of roof space…. so tempted to add a further chunk to our existing 4Kw installation.
