had to dig this thread out as didn't want to start a new one but possibly looking at solar panels and wondering if anyone has recently had them fitted, see loads of adverts.in social media but not sure I trust them so obviously recommendations is always a good thing, also are they worth it as in when do you get in profit with them?
Had them fitted in Nov 22. 9 panels, but split 6 on & 3 due to design of roof. Means we get sun all day in summer, but we're never getting full capacity from the 9.
We've had over 10,000kWh from them, so at 25p/kWh to buy electric, around £2.5k in 3 years. As ever, not that simple and all depends on your set up.
We've also got battery back up, which we've increased since the original install, and I'd definitely recommend getting batteries. With them, pretty much all of the electricity we use is bought overnight at 7p. The solar recharges the batteries during the day but once full, feeds into the grid, which we now get 15p/kWh for. Take the ability to move virtually all consumption to overnight and the feed in tariff and I'd say they've been worth a lot more than the £2.5k above, although I've given up trying to calculate the savings.
Find a decent installer and they will give you a reasonable estimate, although takes a bit of time to compare, as different systems, batteries etc. I've seen there are premium panels available which increase production, although not sure of the cost difference. We used askrenewablesolutions based in Wigan and were really happy with them from their initial contact and quote through to undertaking the work, including having to replace a panel that was damaged when they took it off the pallet.
My suggestions based on our experience:
- Work out your rough daily electricity consumption and aim for at least that in battery capacity, as on cloudy winter days you'll generate virtually nothing, so need the batteries to cover everything.
- Get a larger inverter (5kW, I think) as ours is only 3.5kw, so if you have the oven and kettle on, you can go over the inverter meaning you have to take power from the grid regardless of solar production or size of batteries.
