Solar Panels ,

[Tony50]

We had 200 watts on the Motorhome , is 4 k/watt enough for a 2 bed bungalow using 200 k/watts of electric per month , mainly used on that Tumble dryer Grr.

On the house, if you have space, 6kwp should cover all your needs better than 4kwp. But even 4, will make a nice dent in that 200kwh a month.

Thanks for info , we have bee quoted for a 4 K/W £5448 ,plus £790 for scaffolding
and £7330 for a 6.7K/W system plus £790 for scaffolding .all subject to survey !!
As a option we can have a "Eddie"" supplied / fitted this is a device that will put excess electric via the emersion heater in the water tank to heat the water , which is usually heated by gas

4kw should be ok for you except for maybe darkest winter. We had 2 pylon lithium batteries to cover our use during the dark hours. Best to use power hungry appliances when the sun is out,

If you are located from Birmingham north, the 6,7kw makes more sense, and you will not regret it. Prices will only go one way. A diverter is nice to have, if you got immersion cylinder.
By the way, it’s a fair quote price.

I've just fitted 4kW to our house. We use about 200kW/month so over the past 3 weeks we've reduced our usage from £1.90/day to 60p/day @ 27p/kW on a fairly sunny period.
I DIY'd for a bit under £1k so not sure how competitive your quotes are.

Get a UPS fitted at the same time and you’ll save even more.

Did you buy all the materials from one supplier?
I am having trouble locating stuff especially roof rails.

At £1k the payback time is going to be pretty quick. Just wondering if the advice for anyone looking at paying a company to fit the panels might be only do so after you have insulated to a very high standard.

Me not savvy Electrical what is a UPS ?

Me not savvy Electrical what is a UPS ?

It’s an uninterruptible power supply. Initially introduced to provide emergency power to server rooms and the like in the event of a power cut. You have a battery bank that is charged from the mains and then powers systems if the mains fails. You can get a battery bank installed at home which is charged by PV/mains during the day and then releases power back to your home through an inverter

I am having trouble locating stuff especially roof rails.

I bought the main bits 2nd hand from ebay or facebook marketplace tbh - I mounted the panels myself on painted & treated timber rails rather than aluminium since I couldn't get anybody or any system to fit to existing (asbestos) roof fittings (couldn't drill panels) and I'm a cheapskate and figure they'll last quite a few years on my outbuilding roof and will be obvious enough if they want to fall off. All the leccy bits were off fleebay, screwfix, local wholesaler etc..

Panels are low ish level (outbuildings are work in progress)



I used two 2kW invertors on separate circuits for some redundancy



I grid-tied the system as the invertors won't work otherwise and had them OK'd by my electrician cousin. I had a new smart meter fitted this morning by British Gas and they were more than happy with the install so very happy at that, and can now see when I'm importing or exporting those precious watts (although they can't get the separate control box to sync so only have limited view of usage until they update something in July)

Insulation is a must nowadays . I'm planning to insulate the funk out of my project house, although solid brick walls and 18th Century construction will have it's challenges .
