BP Solar 3 Series 

The BP Solar 3 series models are advanced photovoltaic modules that incorporate polycrystalline cells using SiN coating to give superior efficiency compared with same rated modules from other manufacturers. All the solar panels have “ARC” glass, an anti-reflective coating with self-cleaning properties so that under normal conditions panels do not require cleaning. The modules are robustly constructed using BP’s clear anodised Universal frame and are offered with a warranty that will give you confidence in your system for many years ahead.

12V Solar Battery Charger 

The 3 series solar modules have a 12V nominal output and are ideal for battery charging applications such as off-grid homes and buildings such as stables and barns, remote telecommunications, navigation equipment, motorhomes & caravans, sailboats and other sites where low power is needed. Solar panels can be connected in parallel to increase power and are modular allowing the user the flexibility to build up a system over a period of time in line with budgets and power requirements. Connect in series to increase voltage to 24V, 48V etc.
