Solar Photovoltaic (PV) technology allows to convert sunlight directly into electricity. Here is how it works.

“Photovoltaic” comes from the process of converting light (photons) to electricity (voltage). PV technology was discovered in 1954 when scientists found that silicon (an element contained in sand) created an electric charge when exposed to sunlight. Today, Solar PV is a proven technology which provides electricity to millions of homes and businesses worldwide.

Our solar PV systems are made in Germany and include the following components:

Inverter. An inverter converts Direct Current (DC) into Alternative Current (AC) which is fed into the PUC grid. The number and size of inverters depends on the total capacity of the PV system. Residential PV systems typically require a single phase inverter of 3 to 5kWp, while large PV systems for industrial use may require several three phase inverters up to 25kWp each. A typical inverter measures 500 x 500 x 200mm and weighs between 25 and 60kg. Inverters can be fitted with communication devices to monitor production remotely via internet

Tip. In addition to converting DC power to AC power during the day, an inverter also monitors the voltage and frequency of the PUC Grid. If there is a PUC power cut, the system will shut down even if the sun is shining. This is a safety requirement so that no power is fed into the grid while PUC maintenance crews are working on the power lines. If you live in an area plagued by power cut you may want to consider a PV system with batteries.
