PatioSun Duo

The two-panel PatioSun kit: 890W of bifacial panels against the same 800W microinverter and the Lite's single 445W panel. Same pre-installed steel mount and sold direct, at roughly £250 more than the single-panel Lite.

PowerXpress Plug-in Solar 920W

The 800W in Screwfix's listing title is the microinverter's AC output; the panels total 920W (2 × 460W), and both figures are correct and describe different parts of the kit. Sold with fixings for wall, floor or balcony mounting, but Screwfix's own spec table states a 1-year manufacturer guarantee, well short of the 10-year panel warranties common elsewhere in this catalogue.
