In ALFA electronics we are using the solar energy to power up devices who works away from the main electrical network.
We place solar panels which solar energy is converted into electricity. -Usually 12VDC or 24VDC-. If it necessary, placed accumulator (battery) so the system operation to be possible to work when the solar energy is not sufficient. The battery is charged automatically by the available solar energy. The devices that work by solar energy can be:
Lighting systems, lighting metering, reporting, vending machines, e.t.c.
