James C  Winsley
6.30 kWp Array - 3.68kW Inverter - 5kWh Battery
Predicted annual production 6000 kWh

Using AI algorithms, the system predicts household energy needs and optimizes when to use, store, or export power, based on Octopus Flux’s variable tariffs and real-time electricity prices. This intelligent setup helps households prioritize self-consumption, reduce grid dependency, and benefit from lower rates during peak production. Additionally, the AI can interface with smart home devices to align energy usage with times of high solar output, ensuring energy is used most cost-effectively throughout the day.

Thomas L  near Bath
7.05kWp Array - 3.68kW Inverter - 7.5kWh Battery
Predicted annual production 6700 kWh

"After researching a myriad of solar panel suppliers, we gave up due to need for multiple contractors, exorbitant quotes and lack of confidence of those we spoke to. Then, through word of mouth, we came across John Boyce and his team at 8minuteenergy. What a revelation! Not only extremely reasonable on cost but a demonstrable expertise of the subject and ability to layout the system ideally suited to our needs and position. Couldn’t have been easier, more trustworthy, and installed up and running more quickly than we could imagine. We have absolutely no reservation in recommending 8minuteenergy to anyone seeking the ideal solar solution for their needs. We couldn’t be more pleased with the outcome!"

"We are delighted that 8 Minute Energy developed our solar system earlier this year. From day one they made sure we were making informed decisions and that the installation was suitable for our business needs.


8 minute gave us the confidence that they were not just installers but were keen to understand what our aims were. They helped us throughout the process making sure we understood what was going on and making sure we understood the detailed technical aspects of the project too


There seems to be a great deal more than just an installation as the systems are more sophisticated these days and 8Min Energy have been with us along this journey to establish the most efficient use of our solar electricity production."

Nicky S-P Bradford-on-Avon
7.65kWp Array - 3.68kW Inverter - 7.5kWh Battery

"We had quotes form other suppliers but they just wanted to sell us an off-the-shelf system and were very pushy.  John took a great deal of time to explain everything in detail and whilst they were not the cheapest, 8 Minute were definitely our first choice!"

Edward T Bradford-on-Avon
15 kWp Array - 11kw Inverter, 13.5 kWh storage 
Predicted annual production 13,000 kWh

After fantastic reviews from my local community I enlisted the services of 8 Minute Energy to undertake the installation of a set of batteries to store the electricity produced by my existing solar array. They identified that I could increase the number of panels on my roof by 5.1kWp meaning the batteries could be charged faster. The installation of two inverters, the extra panels, the 13.5 kWh batteries and a Bi-Directional meter was hassle free and quick. The ongoing assistance since installation in providing all the documentation required for my energy supplier and all the question answering has been handled efficiently resulting in the whole project being seamless. I can’t recommend 8 Minute Energy enough.
