Forms of solar projects

There are majorly three types of solar power station, including rooftop solar, ground-mounted solar and floating solar.

Rooftop Solar:

A rooftop PV system is a photovoltaic system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure.

Comparing to the other types of solar system, rooftop solar are usually smaller with capacities in the megawatt range. Rooftop PV systems on residential buildings typically feature a capacity of about 5 to 20 kilowatts (kW).

 

Ground-Mounted Solar:

Ground-mounted solar is usually the most common choice for developer or homeowners with enough ground space. It requires infrastructure that will excavate an area to install the mounting structure that will support the panels.

Due to its scale, which is usually larger than the other types of solar system, ground-mounted panels typically produce more power, but is also not as cost-effective as rooftop solar.

Floating Solar:

Floating solar refers to a solar power production installation mounted on a structure that floats on a body of water, typically an artificial basin or a lake.

The main advantage of floating solar plants is that they do not take up any land, except the limited surfaces necessary for electric cabinet and grid connections. Their price is comparable with land-based plants, but they provide a good way to avoid land consumption.
