Solar Quote

askandlearn1

I have been quoted the follow for solar panels, battery and EV charger.

12 445W panels + 10kwh enphase battery + 12 enphase microinverters + (scaffolding, everything needed for the install + ev charger) = £11,675

12 445W panels + 5kwh enphase battery + 12 enphase microinverters + (scaffolding, everything needed for the install + ev charger) = £10,877

Panels are J A Solar 445. 

Not sure if I need the extra battery but to add it on does not seem too bad. 

I will probably use  circa 5000kwh a year now that I have an EV. Without it was using 2500kwh a year.

Do quotes that seem reasonable  ??

Thank you.

Looks like an Octopus Energy quote? Installers I use to help others can do better!

12 X Eurener 500W bifacial panels (6kWp)
  1 X Tesla PW3 (13.5kW) with Gateway 2
  1 X Zappi EV charger 

~£11.5K full installed. Birdnetting, 10 year workmanship warranty all included. Hope this helps give your perspective!

Enphase is decent kit, JA Solar panels are a budget brand. The quote with the larger battery sounds better, although without the EV you're not really using enough electricity to benefit from a battery.

(Even with the EV, if you're planning to use an EV tariff you might not really need a battery.)

Screwdriva would tell you that for about £14k you can have a system with premium panels and a Tesla Powerwall 3, which I'll agree is a more capable system but whether you think the extra cash is worth spending is entirely up to you.

Should be able to do it for less than quote 1, while offering the PW3's additional storage and higher panel performance! 

A SolarEdge system should be £5.5K without a battery but no Intelligent Flux tariff then!

Thank you both for your thoughts which help greatly. 

I agree battery might not be needed as the overnight charging tariffs work well and are adequate for my current needs. Though think that adding batteries in future may be more costly so maybe worth taking them up now. 

Cost does play a part so need to balance this with the options available including finance.

Very grateful for your input. Thank you

Bear in mind that you can charge the battery at EV overnight rate as well, specially useful in Winter when you'd otherwise be using full price electricity during the day.

That is a very good point Qyburn. Thank you.
