Photovoltaic (PV) cells, commonly known as solar cells, are at the heart of solar energy systems, converting sunlight directly into electricity through a series of precise energy transformations. At SGOB, we specialize in high-efficiency photovoltaic transformers and solar energy components that maximize power conversion and grid compatibility.

FAQ on photovoltaic energy conversion
A photovoltaic cell undergoes multiple energy conversions to produce usable electricity:
Solar Radiation to Electrical Energy (Photovoltaic Effect)
Sunlight (photons) strikes the semiconductor material (usually silicon).
Photons with sufficient energy dislodge electrons, creating electron-hole pairs.
Direct Current (DC) Generation
The internal electric field in the PV cell separates electrons and holes, generating DC electricity.
DC to AC Conversion (via Photovoltaic Transformer & Inverter)
The photovoltaic transformer adjusts voltage levels for grid compatibility.
An inverter converts DC into alternating current (AC) for household/industrial use.
Energy Storage (Optional)
Excess electricity can be stored in batteries or fed back into the grid.

✔ IEC 60076 & IEEE C57.12 compliant
✔ 20-year operational lifespan
✔ Lightning & surge protection
A: A PV cell first converts sunlight into DC electricity via the photovoltaic effect. The photovoltaic transformer then steps up the voltage to minimize transmission losses before the inverter converts DC to AC. SGOB’s transformers ensure maximum energy retention (up to 99% efficiency) by reducing resistance in long-distance power transfer.
