Get ready to be cold and poor in 2025

Like I said, not very good.

"In average UK weather conditions, you can expect one kilowatt of panels to generate between 700 and 900 units (kilowatt-hours, kWh) of electricity per year."

That's just over 2 units per day. (Equivalent to the panel being in full sun for 2 hours per day.)

If you're outside a city, and have a decent sized garden, you may get better ROI with a wind turbine.

You must have a poky house 20m is hardly big. I have a shed that size.

so 2700kw on 3kw or 4500kw on a 5kw array.

Enough for a normal family home

• Domestic systems tend to range from 1 kilowatt (kW) to 5kW in size.
• A 1kw system can produce around 850kw per year, a 2kw system 1,700lw per year, and a 5kw system 4,500kw per year.
• The Energy Saving Trust (EST) estimates that a typical three-bedroom home in the UK will use just over 3,000kw per year. So, a 4kw or 5kw system would cover this.

20m?

The panels are cheaper than they used to be but it will still take several years to recover the cost of the system.

3000kWH/year = £600/year

--------------------------

You have to have your BS detector on when looking at this alternative energy stuff.

Stories abound of people being sold wind turbines to put on their roofs in cities. Or OAPs being sold solar systems where they'd be long dead before they recovered the cost.

Mini-nukes from RR should do the trick

I really like the idea of a dirty nuke bomb just outside my house. Especially if I lived in Swansea.

How much does a solar PV array cost?


Prices collected from the MCS scheme (see below) in early 2020 show an average of about £1,500 per kilowatt for small installations. So a domestic array of 3.7kW (about 25 square metres) would cost about £5,500. Larger systems, of 10 to 50 kW, have an average cost of about £1,000 per kilowatt.

so £4.5K /£600 is 7.5 years break even. Assuming a lifetime of 30 years that is 22.5 years of profit (£13.5k) not a bad return.

It's not about annual production, it's about how much you can use. If you don't have a way to sell your surplus, you could be wasting most of what you generate if it's an erratic supply.

They should make PVs with built in mining hardware that runs when they're not under load.

Most of the PV panel controller have the ability to read the output and house usage. You just need to connect up and then ramp up and down the mining rigs with some software.

The heat generated can then heat up your private indoor swimming pool

As mentioned before, storage heaters, immersion heater, electric car, powerwall and still get your surplus payments if on the original fit.
