Sanyo high performance modules are more expensive, but perform up to 10% better than other modules. They are also power dense, which means that they squeeze in as much power as possible into a given roof area. This is particularly beneficial when trying to maximise a smaller roof space.

Solar Century C21e Tiles and Slates are ideal in a new build or when a re-roof is needed. They blend in with the roof tiles, which makes them the first choice for when aesthetics are a key priority for an installation.

Solar Century M185s are entirely black with a black frame. These modules look great and are also of a superior efficiency to alternatives.

Day 4 modules utilise an anti-shading technology, great for roofs that have shading issues.

Sharp modules are assembled in the UK and are a good, all-round, solid performer.

Yingli modules are affordable, robust and come in a wide range of sizes for all needs.

BP Solar are very high quality modules with a good performance, from one of the world's most experienced solar panel manufacturers.
