What are the proven results of Renew solar systems?
The easiest way to answer this is to look at a real system.
Below is real, lifetime data as of December 2025 from a Renew solar and battery system installed in early 2024. These numbers come from the system itself, not estimates or predictions.

What actually happened?
Since it was installed, this home has:
Generated 24.8 MWh of electricity from the sun
Used 19.0 MWh to power the home
Exported 11.8 MWh back to the grid
Imported 7.6 MWh from the grid
Used its battery to store and reuse energy 7.0 MWh
In simple terms, the home has made more electricity than it used and shared the extra with the grid.
How does this save money?
The savings come from three simple ideas.
1. Generating your own solar instead of buying electricity
When the sun makes electricity and the home uses it, that’s electricity you don’t have to buy.
Over its lifetime so far, this system has done that enough to save approximately:
£2,500
2. Getting paid for extra solar
When the home has more solar than it needs, the extra goes back to the grid and the homeowener gets paid for it.
So far, that has earned:
£1,168
3. Using the battery
The battery is used differently through the year:
Spring to summer: it mostly stores surplus sunshine for later, factored into saving in 1.
Autumn / winter: it is charged overnight when electricity is cheap and used later when electricity is expensive.
Using the winter charging from the grid amounts to around: £400
So what is the total saving so far over the life time of the system (approx 18 months)?
Add those three together:
Using solar instead of buying power: £2,500
Export payments: £1,168
Winter battery savings: ~£400
