Previously mainly centralised solar power generation, rooftop solar power generation is now the mainstay.

As one of the mainstays of distributed photovoltaic power generation, idle industrial and commercial rooftops are being fully utilised. At the same time, many residents have also installed rooftop solar power stations on their own roofs.

When building a home solar power system, how do you estimate the load-bearing capacity of the power station? How is the weight that the roof can carry calculated? This is an issue that should be considered carefully at the outset of the design of a power station.

Here's an example: a 3KW home rooftop solar power station requires 12 280W solar panels, the weight of the 12 panels is 216kg and the floor space is 21 square metres, so the pressure of the solar power station equipment on the roof is calculated to be 10kg/square metre. Domestic roofs generally have a load-bearing capacity of over 30KG or more, so there is no problem installing a solar power station on them.

In general, professional PV companies will take the above factors into account when designing rooftop solar power, so users can install and use rooftop solar power with confidence.
