Are there any updates to this? It was starting to get interesting ……

I filled in the PVGIS which shows summer max of 1200 kWh and winter low of 200 kWh. I’m presuming that this is an average for the month so some days would be higher and some lower. it’s quite complicated but at first glance the simulation shows 20% loss on a 10 kW system. does this fit in with anyone else’s experience?

Sorry Steamy what is PVGIS please?

So getting back to the question - solar pv is not viable in the winter as an alternative?

Well that doesn’t sound very promising then. most electric used in the winter for space heating if it is so bad in winter why is the Country bleating on about renewables? Seems we have to have pv for the sunny days, wind for the windy days and try and live by the sea for the wave power. thanks for the replies

So I’m looking at pv with the hope of being self sufficient with battery back-ups. is this just a pipe dream?

It would be interesting to hear from anyone who has actually used a multi foil product to see how it performs in the real world. when I last built a house in 2009 my BCO would not accept multi foil at all as it was a fairly new product. most ‘sensible’ people seem to be of the opinion that it is all smoke and mirrors but it would be good to hear real life experiences good or bad.

We are off mains gas so very high consumption of electricity 13000 kWh Even taking a loan payback would be less than five years and still be cheaper than our electric bill. Most of it for space heating and laundry in a small business in the summer excess units returned to grid at 5.5p could be worth about £3 per day why am I hesitating?? don’t know the contractor don't know the system don’t have £16000 quid lying idle in the bank etc etc i appreciate on costs for running a company so was just looking for some typical costs as a guide may look at a ground array and see if it would be cheaper? thanks for the replies very helpful

Hi all just had a quote for a pv system with battery backup. 24 x 375 W panels and two batteries. All fitted and turnkey by Go-Energy £14750 + VAT with maybe some shaving to be done. £600 if I want to be part of selling any surplus back to the grid. i know it can be done cheaper DIY but it’s not for me. anyone had a quote from any contractors for anything similar?

Situation is barn will not be done anytime soon. When it does get converted it will be to maximum insulation standards! We are 85% electric for energy with some lpg for van heating. Our electric bill is estimated at over £3K this year. We use a lot for laundry and space heating for customers visiting our beauty salon. It is a modern steel frame barn with a south facing roof of 22mtrs x 4 mtrs with a pitch of about 11 degrees. We also have large grounds where we could mount a floor based system. I'm looking to replace the grid as much as possible rather than obtain an income. Is there a good starting point such as book or recommended supplier? I'm starting with eBay suppliers and found several supplying 4-6Kw systems with battery storage from £4K Be nice to know who/what to avoid Thank you for taking the time to share your knowledge.

thanks for the advice ?

OK so just got a shock with my new electricity deal as my fixed term has ended. Tried Uswitch - after registering etc etc comes up with NO DEALS AVAILABLE I am now considering installing PV panels. We are doing a barn conversion and living in a static on site. Most of out consumption is during the day as we run a business from the site as well. My estimated usage is 13000 Kw per year mostly in the winter as used for space heating and drying as there is no mains gas. Does anybody know any options before I call installers for a quote?

we are looking at this just now and trying to decide whether to have engineered wood or tile or vinyl. Wood always looks nice but all these options add extra layer of finish and therefore cost. Has anyone polished their concrete screed to achieve a finished surface or I am being stupid? What are the downsides of polished concrete?

Is this the intellectual equivalent to 'come outside and say that?'
