5 vs 10 Solar Panels with Battery from Octopus – Advice Needed for Future EV & Heat Pump
Comments

At £140 a month is it even worth it?
I assume you on a standard rate 25/kWh.
When you get an electric car you could switch to some of the cheap 6p overnight tariff, especially with heat pump running on that rate your bills will significantly go down (as well as savings).
Why they estimated bill £240? Well to hype the savings, £200 saved a month shows that system pays itself back in 5 years, if you save £70 a month then we're talking 10+ years.
If you want to be green then you could consider investing in renewables like Bluefield Solar, Greencoat UK Wind etc. they pay close to 9% back (probably what your system would earn you).1 -

But that again costs you about £1000 as that's what you could stooze over 2 years.QrizB said:Screwdriva said:

This is what I did. Effectively I'm using the savings on the electricity bill from the solar to pay off the cost of installation via minimum monthly repayment on the credit card. Been going 3.5 years now. If 0% deals keep cropping up for transferring the capital, then it will eventually pay for itself!QrizB said:Screwdriva said:

^ I would try to achieve the lowest price possible for the system and then use a 0% loan from a credit card (not Amex - installers don’t accept it) or a green mortgage type loan from a bank (eg Nationwide).

So long as that sort of price is actually on offer. I found that actual quotes came out a good 30% higher that the "shouldn't cost more than" figures bandied about on here. Or "no bid". Ultimately you have to choose from installers actually working in your area, and not pay too much attention to "shouldn't cost more than" figures from the other end of the country.12 X 500W Eurener bifacial panels + Tesla PW3 = £11K installed. Why pay Octopus more for less?0 -
What I have shared above is valid for anyone in England/ Wales with a reasonably accessible roof, within a couple hundred quid.

Thank you. I am now more inclined to get the bifacial ones with the Tesla powerwall 3 but I still have a few questions pleaseScrewdriva said:

12 bifacial panels (or more) if the installer can fit them. I'd ask your installer to paint the invisible area behind the panels with reflective white paint to maximize albedo gains, as most light passes through a bifacial panel.Sam3007 said:If the space on my roof is limited , Is it better to space 10 bifacial panels with gaps to boost rear-side gain, or just install 12 panels close together (6 on each side)?
I'd do it all at once to save on installation cost and put it on the 0% credit card and use the earning/ savings from the intelligent tariffs to pay off the credit card payments. That said, finances are a personal thing - you know your situation best.Sam3007 said:

None that I know of sadly. The Solar industry is very disjointed, brimming with cowboys selling poor quality components. This is a big part of why I do what I do.Sam3007 said:What’s the best website to search for competitive solar quotes where I can pay by credit card if 0% instalments are not available?- 10 x 400w LG Bifacial + 6 x 550W SHARP BiFacial + 2 x 570W SHARP Bifacial + 5kW SolarEdge Inverter + SolarEdge Optimizers.
