Solar installation in NW required

35 Posts


Like many I’m seeing a benefit in going down the domestic Solar PV and battery route.
I’ve seen lots of information on YouTube and online, so have an idea what I want. Problem comes with finding an installer.
Just had Project Solar round to quote, requested 90mins to measure and quote, which turned into 4hrs. Sales rep only had info on the roof panels and guarantees, nothing about the inverter or batteries. Even when calling the technical helpline they didn’t know much more. Wanted £28k and couldn’t understand why I wouldn’t sign up on the spot. Said he wouldn’t be able to come back if I decided to accept, despite being available 1day after requesting a quote.
Reminds me of a SafeStyle double glazing salesman from the 1990s.
Still need to find a quote and reputable installer. The PS quote was for 33 panels on 3 aspects, which was more than I expected. I’d asked for 23 panels on 2 aspects, 17 south and 8 east. The main roof is south and whilst I didn’t think shading was an issue the salesman thought the chimney would reduce effectiveness by 25%? I would couple this with a 9.5kwh battery and 6kw inverter.

I’ve used the Great Homes calc and based on other installation costs have a rough idea on payback period.
I’m located in the North West of England.

2.72kWp PV facing SSW installed Jan 2012. 11 x 247w panels, 2.5kw inverter. 28MWh generated, long-term average 2.6 Os.
1) With such a large roof surface area for PV, is a battery something you will actually benefit from (vs. selling at 0.15p/ kWh minimum)?
2) Chimney shading can reduce yield, so it's best if you went with optimizers to mitigate this (we did too). Was the third aspect West facing? If so, I would agree that coverage across all 3 aspects can be especially lucrative for generating during the whole day (vs. peak generation during the mid day).
Best to go with a local installer who will supply quality brands at non-extortionate prices. They do exist.
- 40% of panels in an East/ West rooftop orientation.
- Viessmann 200-W on Advanced Weather Comp. (the most efficient gas boiler sold)
2. I need some advice on optimisers as I’ve seen some conflicting information about whether the whole string goes down when one panel is shaded or not. The 3rd aspect faces north, so one I’d be less inclined to use.
The search for a local supplier continues. Good to see a few recommendations in this responses.
The chimney is approx 3-4ft plus the pot another 2ft.
