Perlight 300W Delta Mono PERC 54 Cell All Black MC4-EVO2 Solar Panel
Perlight 300W Delta Mono PERC 54 Cell All Black MC4-EVO2 Solar Panel
The Perlight Delta is an Monocrystalline silicon 158.75 × 158.75 mm solar panel. It delivers 19.9 % module efficiency from a 1,504 × 1,002 mm frame.
About the Perlight Delta range
The Delta range is Perlight's compact mono module, sized for small roofs, outbuildings and off-grid installations where a full-size panel will not fit.
At 1,504 × 1,002 mm it is a residential-format module, sized to fit the rafter spans and roof planes of a standard UK house. The black frame and dark cells keep the array visually quiet on a front-facing roof.
Why installers specify this panel
- −0.40 %/°C power temperature coefficient — output falls away more slowly as the modules heat up through the middle of the day.
- All-black appearance — a black anodised frame and dark cells, for domestic roofs where the array has to be discreet.
- Long-dated warranty — 30-year warranty.
