If you have solar panels, then yes, lots of sunshine is great.

Its the same with storage batteries - charge them up overnight at the cheap rate, and use them during the daytime (4pm - 7pm is best) or export if not needed.

However, there is (of course) one big issue here, which is why everyone isnt doing this.

It costs a lot of money to install solar panels, or storage batteries, or both (even with grants).
You may be saving on your actual energy bill, but it takes years of those savings to get back what you paid out.

Its the same with wanting everyone to use heat pumps.
Out of interest, I got a quote from Octopus last year for replacing my boiler with one.
For comparison, I also got a couple of quotes to replace my boiler with a similar model.
I have no intention of actually doing this as its only 3 years old, I just wanted to see the cost.

Even with grants, the heat pump was almost triple the cost of the gas boiler.
