Solar panel advice

mse1234

Morning all,

I've been thinking about installing solar panels as we need to do some minor roof repairs and will have scaffolding for that (makes sense to do any solar at same time).

I'm based on the south coast (hampshire) and we have had the rear extension built now (not showing on Google satellite map yet). The house is South East facing so front gets morning sun and back evening.

Currently use around 6000kwh electricity annually, but this may increase as I'm also considering AC units for 3 upstairs bedrooms. 2 of us work from home, so energy use is constant from about 7am through to 11pm. No electric cars and no plans for them.

From reading other posts I'm sold on the Tesla powerwall 3 battery and ideally would want to get as many panels as the roof would take and be worthwhile generation wise.

Anyone recommend any installers or point me towards what I could do here/should look for?

thanks in advance

I could be wrong but is the roof in question under the #38 in the Google Earth diagram?

If so, looks like more roof surface area is SW facing? Given the extension has a flat roof, it looks to me that you will be able to fit:

2-3 X Eurener 500w bifacial panels on the SE aspect

6-7 X Eurener 500w bifacial panels on the SW aspect 

6-8 X Eurener 500w bifacial panels on the flat roof. 

All paired to the Tesla PW3. The installers I use to help others quote < £13K for this including a 10 year workmanship warranty and bird netting. 

Hope this helps!

Thanks - do you know installers that cover this area or should i use this as a guide and contact someone from mcscertified for quotes: seems a lot of companies, but many seem to be fairly new and no/not much companies house history

Always happy to do what I can to help all MSE forum members! 

This phenomenon is quite common - loads of cowboys in Solar PV. I'd recommend checking companies house to see how long they've been trading (ideally 7+ years) , carefully reviewing Trustpilot scores and Google Reviews, and make sure they offer a 10 year workmanship warranty alongside quality PV brands.

I used Orangesolar, based in Southampton. They've been around a while. Our install is about 3 years old and no issues. They came back and fitted some more panels and bird netting last year when we had jackdaws nesting under it.
We just took what was offered at the time but I'm sure they could source any manufacturers equipment.

Just a suggestion - I have no-one else to compare them against!
