What is a solar photovoltaic power generation system?

IMPORTANCE OF CHOOSING SUNPIN Solar photovoltaic power generation system is a new type of power generation system that utilizes the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy.

Can a photovoltaic system be connected to a building electrical installation?

Indeed, a photovoltaic system can be connected to the building electrical installation at different places: to the main low-voltage (LV) switchboard, to a secondary LV switchboard, or upstream from the main LV switchboard. These options, their advantages and drawbacks are discussed in this blog post. 1.

Are photovoltaic energy sources a challenge?

Buildings today are increasingly integrating renewable photovoltaic energy sources to supply power for the building loads. For those designing such an electrical installation, the integration of photovoltaic sources can be a challenge.

Can a photovoltaic inverter convert a solar panel?

If the conversion of the power produced by the solar panels is done by more than one photovoltaic inverter, it is recommended that the output of those inverters be grouped by connecting them to a secondary LV switchboard, which is then connected to the main LV switchboard at a single point.

Can a PV system be connected to a secondary switchboard?

In this case, connecting the PV system to a secondary or main switchboard would overload the existing electrical infrastructure and would require its modification, such as replacement of cables, switchboards, and protection equipment.

What is LV switchboard vs PV?

This approach is used primarily in existing multi-floor buildings, where the PV production, usually on the roof, is far from the main LV switchboard, which is usually at ground level. Indeed, in such situations, the cable length between the PV system and the main LV Switchboard can be considerable.
