The BP SX20 solar panel provides cost-effective power for DC loads with moderate energy requirements, and is suitable for applications including remote telemetry, instrumentation systems, security sensors, signals, and land-based navigation aids. With 36 multicrystalline cells in series, it charges batteries efficiently in almost any climate. Cells are laminated between sheets of ethylene vinyl acetate (EVA) and high transmissivity low-iron 3 mm tempered glass.

BP SX20 modules are available in the M and U configurations, which includes the heavy-duty universal frame and a high-volume junction box with dual-voltage output. The large (411 ccm) junction-box of the U modules is raintight (IP54 rated) and accepts PG13.5 or 1/2” conduit or cable fittings. With its six-terminal connection block, it enables most system array connections (series or parallel configurations) to be made in the junction box itself. The BP SX20U junction box may be field-wired to provide 12 V or 6 V nominal output. The BP SX20M has a fly lead and a slightly thinner multimount frame. 6V modules are intended to support 6V loads, and are not recommended as series elements in higher voltage arrays.
