The right solar panel for a UK home depends on your roof, not on a ranked list.
A standard pitched tiled roof calls for maximum efficiency per square metre; a shaded roof needs back-contact cell technology that handles partial shade without losing a third of its output; a small roof may need a high-voltage panel just to turn the inverter on in winter. Spirit Energy’s design team specifies panels based on roof type and constraints first, and across more than 6,000 installations across England, that approach is what separates a well-performing system from an average one.
