BYD 280W 24V HALF-CELL PHK-30-SERIES-5BB 275-285W Polycrystalline Solar Panel

The BYD PHK-30-SERIES-5BB 275-285W  280W 24V Half-Cell polycrystalline module is a 144-cell Half-Cell polycrystalline module manufactured by one of the leading manufacturers of BYD photovoltaic solutions. This  BYD solar panel has a 10-year product warranty and a 25-year linear power warranty, with efficiencies hovering around 80% to 97.5% over the age of 25. The newhigh-efficiency BYD PHK-30-SERIES-5BB 275-285W panelesare designed with 144 split cell technology, which prevents power loss and contributes to maximum performance even when the module is affected by partial shadows.

The 280W BYD PHK-30-SERIES-5BB 275-285W BYD solar panel is a high-quality polycrystalline module, ideal for solar self-consumption solar installations and industrial applications that need to produce maximum energy performance. Lightweight and resistant solar plate, made of polycrystalline silicon with anodized aluminum frame.

BYD PHK-30-SERIES-5BB 280W and 144 cell solar panels can be combined with state-of-the-art lithium batteries as well as traditional lead-acid and GEL/AGM batteries with their corresponding charging regulator. In Supplies of the Sun we offer world-renowned solar panels as well as all their components, both in their solar inverters, solar panels, charge regulators and batteries for solar installations.
