Sharp ND-AC275 is a photovoltaic panel manufactured using polycrystalline cells. Two technologies dominate the market: polycrystalline and monocrystalline cells. Monocrystalline cells are usually more efficient, but more expensive to produce, and polycrystalline cells can be produced at an affordable price, but have a slightly lower performance. After all, it depends on the roof surface which technology will be more beneficial for you. If you have limited space, you can achieve the highest energy production with monocrystalline cells.

[1] STC = standard test conditions: exposure 1 000 W/m², AM 1.5, cell temperature 25 °C. Rated electrical characteristics are within ±10% of the indicated Isc, Voc and 0 to +5% Pmax (power measurement tolerance ±3%). The reduction in performance when changing from 1 000 W/m² to 200 W/m² (Tmodel = 25°C) is less than 3%.
[2] NMOT = Module operating temperature: 45 °C, at 800 W/m² exposure, 20 °C air temperature, wind speed 1 m/s.
