And how many pounds does it contribute to the thousands you spent on the solar installation?
300W currently costs me about 7p per hour.

Your South facing panels must be facing in a strange direction.
Mine face due South.
In summer, at 6am, they see a little scattered light off the clouds, but the sun is actually falling on the other side of the roof.
My real-life, actual December generation varies between 2.3kWh and 4kWh daily average, varying by year depending on the weather.
My real-life, actual July generation varies between 10.6Wh and 19.2kWh daily average, varying by year depending on the weather.

mine are dual layer called hybrids/HIT back in the day - its old tech now, but they are designed to work well in cloudy days not just sunny days

They cost more and frankly probably not worth it.

Are you in Australia?
I've been recently wondering about adding in a solar system on our west facing roof - we're on time of use tariffs, so the electricity at that time of day costs us more to import, and we get a better price for selling it.
As someone said earlier - if you've an EV (if it's often there in daytime) or/and you have a house battery, or if you use electricity during the day, it makes quite a difference to the maths.
Solar and ASHP can also work well together, though again you've the issue that you're generating most power at the times when you generally need least heat.

No.
You are surprised.
http://solar-center.stanford.edu/AO/sunrise.html#:~:text=At the summer solstice, the,east and sets due west.
"Most people know that the Sun "rises in the east and sets in the west". However, most people don't realize that is a generalization. Actually, the Sun only rises due east and sets due west on 2 days of the year -- the spring and fall equinoxes! On other days, the Sun rises either north or south of "due east" and sets north or south of "due west."
Each day the rising and setting points change slightly. At the summer solstice, the Sun rises as far to the northeast as it ever does, and sets as far to the northwest. Every day after that, the Sun rises a tiny bit further south."
Something else to throw into the equation - TOU (time of use) outgoing tariffs. Octopus agile outgoing, for example, is paying between 19p and 44p per kWh for export today.

Solar power those things on roofs makes the area look cheap IMO. Thankfully none where we live. I have heard a roofer tell me about the problems with these pannels when vermin/pigeons etc get under them and leaks in roof being much more expensive to repair etc.
So not for us.

Most new builds have solar panels now and they can be fitted in flush mount form. Its also common to close the access with wire to prevent animals nesting. I wouldn't have them on the front one my house and couldn't see them from any angle on my old place.
Thank you.
It may be standard practie around where you live but I can recall it around our way re new build but then there is hardly any.
Re the way they fit them, I'm guessing that they not only less vulnerable to vermin as stated by me but possibly look better.
Anyways, not for me - If we were to go down that route it would be the rear of the house as it is south facing but imo its a con from what i read as the solar people/gov moves goalposts
To be very frank they make any street look naff and stick out like a sore thumb.
Are those prices you’ve guided including the installation?
Im considering the DIY route and installing myself…
Yes, and G98 application.
DIY will save you a fortune, but I'm not sure on the details for MCS certificates and the technicalities of exporting to the grid. People have done their own systems though.

The rent a roof schemes where a con as you are effectively leasing out part of your house and have performance obligation and penalties. If you have eyes on an EV and all of us will at some point and have a south facing roof of a decent size , south of London, its a no brainer really. The earlier adopters (me in my old house) got subsidised for generating electricity. That is because the business case didn't stack up otherwise (30 year payback). Now you can get ROI in 10 years through standard tariffs. With the current hike in energy costs, most PV installers are backed up until the winter.
A medium sized 10-12 panel install will get you around £700 worth of electric a year, payback in around 8-10 years.
@IT Minion the power wall is worth the money just because of the noise it makes [sounds like the love child of Knightrider's KIT and a Cylon, with a deep voice]
is that possible?
I was thinking about solar of some sort (our energy contract runs out in May)
I was thinking that a system which did not connect to the network might be possible DIY -but anything electric which connects to the house electrics has got to be notifiable??
Im looking into these options:
1) solar PV powering a immersion heater and using the hot water tank as a thermal store
2) solar pv with a power wall
3) solar thermal -with a dual coil cylinder
the problem is that doesnt solve the fact my heating is still gas central heating
