Made by SunPower – a name that has set the standard in solar for over 40 years – these are among the most advanced panels available to UK homeowners.
As one of the very few certified SunPower Elite Partners, Infinity Energy Services designs and installs the complete current SunPower range across the south of England.
There are two SunPower panels we install today:
- The flagship M Class, the successor to the legendary Maxeon range; and
- The high-value Performance range.
This page helps you choose between them in under a minute, then points you to the detail you need.
Which SunPower panel is right for you?
Both panels are premium, all-black, glass-glass and built for British weather. The simple way to decide:
- Choose the M Class if you want the absolute maximum performance, the longest warranty and the lowest lifetime degradation;
- Choose Performance if you want outstanding SunPower quality at a more accessible price point.

Solar panels manufactured with a conscience
Not all solar panels are made equally. SunPower panels are produced to high ethical and environmental standards, so you can invest with a clear conscience:
- Responsible manufacturing: a commitment to UN Global Compact principles across human rights, labour, environmental protection and anti-corruption.
- Sustainable operations: a long-standing focus on waste reduction, recycling and responsible lifecycle management.
- Cleaner materials: the M Class is manufactured lead-free and PFAS-free, meeting the strictest European RoHS and REACH-SVHC standards.
Add battery storage to your SunPower system
Most solar systems generate more electricity than you can use at any given moment, and the surplus is otherwise exported to the grid.
Pairing your panels with battery storage lets you capture that surplus, keep the lights on during a power cut, and store cheap off-peak electricity.
