What are heterojunction technology (HJT) solar panels?
The HJT production concept was developed by SANYO Electric in the 1980s (SANYO was acquired by Panasonic in 2009).SANYO was the first company to commercially produce solar cells made of amorphous silicon (a-Si). This thin-film technology, most commonly found in pocket calculators, absorbs a wide range of the light …

Storage batteries are essential for standalone photovoltaic systems as electricity generation is not constant and is not controllable (i.e. depends on solar irradiance). With storage batteries, electricity generated by solar panels can be stored up and used to power the electrical loads when there is no sunlight.
