You might be making some incorrect negative assumptions about energy requirements and renewable on new developments.

Have you checked what your local planning department policies are for new properties in your area?

Are you familiar with Part L of the Building Regs?

I'm not sure if I understand that?

Are there not tariffs that allow you to export back to the grid, and do they not measure how much you send back?

They can't measure how much you put back into the grid but they measure how much you generate in total and pay you a percentage of generated units. I send a reading in every quarter read off the generation meter, I have had my setup for a while now with batteries and as I have an electric always on cooker (like an Aga) I don't put as much back as most people but it makes no difference to the payback.

You learn something every day  :hi:

Well a quick Google indicates that -
Modern smart meters do measure how much you export to the grid
There are also dedicated export meters
Older Grandfathered "Feed in tariffs" assume that you export 50% of the solar

So basically it depends on your set up  :hi:

I have a feeling this might be because, you have an old system?

Smart Metering: Most smart meters (like SMETS2) measure electricity flowing in both directions. When your battery discharges into the grid instead of your home, the meter registers this outward flow as export.

@Blackpool Rock - you beat me to it  :hi:

Yes theri are but thay are very little.

Solar by itself isnt that wonderfull but add on storage and the abiliry to buy power in at the right price plus that you make, then it can be a very good thing.

It can be very good powering home Aircon after all when old Sun is out side cooking you then he can be cooling you.

You can DIY such systems as long as you don't mind roof work and got a mate who;s a scaffolder!..

I think you have to have any system (solar or batteries) installed by a qualified professional to be able to get it registered with your DNO in order to send electric back to the grid.

 :lol:

I read the regs when I have to, but usually in conjunction with a professional in a given area of expertise, quite a bit of it is open to interpretation.

In addition to the UK Buildings, several Local Authorities and County Councils have gone a step further and added their own requirements.

In summary, every new home already has to meet minimum energy and carbon emission performance requirements, a home has to be super energy efficient. There are high insulation requirements, rules to prevent thermal bridging, low u value requirements on windows, roofs and walls. Combine that with mandatory air pressure testing to measure leakage. The result is that you end up with a highly efficient home, and therefore the energy required to heat it is minimal, often negating the cost of installing solar.

For example if you have a Passiv house or even near Passive, you will use hardly any energy for heating, as it heats itself.

That all said, Solar is coming in as mandatory (for the majority of new builds) in the next update as part of the Governments Future Homes initiative.

Think its time to revert to cars
A mate of mine has ordered a Jaecoo
Seen a few of them around they look the dogs
Lurve the lights & the front grille
A lot of car for not a lot of money

This one looks supa

All black inside would look even better & not too dark with the [slideable] pano

I hate an all black interior, so depressing.

I have a panoramic roof on my current Disco, and I had it on an X5. Never use it, lost on me.

A massive 56 miles of electric range :(

The Jaecoo Omodo full electric looks like a smaller Range Rover and comes in at about 25K and a range of 267miles

OK, I suppose it was only a question of time! I do have a current smart meter but I guess it isn't used? Mine was installed in 2017 so I guess I have a legacy account?
