How do solar cells work? Photovoltaic cells explained

A solar module comprises six components, but arguably the most important one is the photovoltaic cell, which generates electricity.The conversion of sunlight, made up of particles called photons, into electrical energy by a solar cell is called the "photovoltaic effect" - hence why we refer to solar cells as "photovoltaic", or PV for short.

DC/AC ratio: How to choose the right size solar inverter?

If you choose a peak power equal to the nominal power, you''ll get an undersized solar field. It means you can get the same energy yield with less inverters —or producing more energy by installing more modules. If you choose a peak power higher than the nominal one, you''ll get an oversized PV plant. This will saturate the inverters over the
