Quotes for solar any good

crey

I am in the market for solar in an effort to mitigate the impact of the forthcoming rises and try to be a little greener.

My annual consumption is just over 3,000kWh.

I am gas fired heating and hot water. Everything else is electric.

The roof slopes face roughly east-west.

I have had several quotes all varying in price and specs.

Most seem to be looking at a 12 panel system of 2 strings of 6. One on each slope. With varying battery sizes from 4 to 8kWh.

I have also had quotes for 9, 10 and 16 panels. But 12 seems to be the sweet spot.

Most are quoting JA Solar Panels with one each quoting  Canadian and Hyundai. Project Solar use their own but prices were way off the rest.

All the 12 panel system design outputs are around 4.6 to 4.9kW with the Hyundai ones highest.

All are quoting Growatt Inverters and Batteries between 5.8 and 8kWh.

Prices are between £9495 and £11430 for all the 12 panel designs.

I'm not looking to go with the cheapest but the best value in terms of service, output, performance over time and after sales support.

There isn't a great deal between the prices but are they in the right ballpark? They all say prices will be rising imminently.

What companies have people used and found to be good? Reviews online seem to be mixed.

Just looking for rough guide to prices for the size I'm looking at and recomendations for any installers used.

I'm in Bedfordshire so and installers would need to cover this area.
