Solar panel advice

Considering solar panels as we are doing double storey extension which have scaffolding.

Have got an estimate from Joju but it seems rather expensive:

System Specification

17 x Aiko 465W N-Type ABC, 54 Cell, Black Frame, Gen 2

Solis S6 6.0kW 2MPPT Inverter 1PH

On-roof mounting system

Peripherals included

Scaffolding Not Included

Immersion Controls: No

Bird Protection: No

Export Limitation Meter: No
£9,460

Battery is another £8,5k

Panels would go on pitched roof facing SW and SE in West Midlands, no shade, annual consumption 3kWh

That's just not good value no matter how you slice it! Here's a great example of a superior quote I've seen just last week from installers I use:

17 X Sharp 425W black panels (25/30 year guarantee)
17 X SolarEdge optimizers (25 year warranty)
  1 X SolarEdge 8kW inverter (20 year warranty)

~£8K installed. Bird netting & G99 included. Larger more capable inverter, optimization, longer warranties and much better component brand reputations.

I'd recommend squeezing in a few more panels if the surveyor shares they will fit on your aspects. I don't believe you need a battery with low annual consumption of 3000 kWh but if you insist, you can have a GivEnergy All in One installed for £6.5K, which will allow access to the lucrative Intelligent Flux tariff. 

You can do way better!

Thanks, which supplier do you use?

I use 4 across the UK now, in what I can only describe as a pro bono cause to help others embrace quality renewables at lower prices. (Not charging a commission helps!) The installer I recommend depends on requirements like budget/ brands required/ location etc. Each is unique but what in universal is their obligation to deliver a great result for the end user.

I've saved thousands over my half decade on MSE forums, so if I can help give back to the community, I view it as a great privilege. Feel free to DM me if I can help!
