SunPower have released their new higher efficiency A-Grade Maxeon Gen III solar cell which is now used in all PremiumPlus Panels giving them some serious advantages over tradition solar panels.


The Gen III cells not only produce 25-35% more power compared to other conventional cells, they’re also more efficient in high temperatures and low light. Maxeon cells also have superior strength and durability allowing them to survive extreme conditions year after year.

When protecting the incredible technology that is the Maxeon Gen III cells, the solar panels have a top layer of ETFE (Ethylene-Tetra-Fluoro-Ethylene). ETFE is a high-strength fluorine polymer that is corrosion and stain resistant, non-stick, self-cleaning, and retains its clarity (and therefore light transmittance) ensuring long service life for solar panels.

ETFE will not discolour or degrade from exposure to environmental pollution, UV light, harsh chemicals or extreme temperature variations.  The textured surface offers an extra layer of protection and robustness and provides a small increase in efficiency due to its anti-reflective properties, which means more light passes to the cells. The ETFE top layer gives the panels a pronounced, tough, textured and robust surface.

The advantages noted above are important to consider when choosing a slimline solar panel, especially when it’s to be fitted to your pride and joy for life. It is also important to understand that when a solar panel gets hot, it will begin to lose efficiency. Being that the PremiumPlus panels start off being at least 25% more efficient, you can be sure to have a solar array that is producing good power when temperatures are high.

The PremiumPlus advantages in power, energy and durability set the benchmark for slimline solar panels. If you’re looking for a lightweight, quality slimline solar panel that guarantees return on investment, the PremiumPlus range ticks all the boxes.
