Disadvantages of solar photovoltaic power generation

1, the early investment is large

Installing a PV system is expensive - at least up front. An average family's monthly electricity bill is about 100 to 200 yuan, if the installation of 20KW photovoltaic system on the roof of the house needs to spend about 80,000 yuan. If a production enterprise installs a 500KW distributed photovoltaic power generation system on the roof of the workshop, the cost is about 1.75 million.

2, occupy the ground area

Centralized ground photovoltaic power stations often cover thousands of acres, of course, the land is originally unused, at least for now.

The industrial and commercial distributed photovoltaic power station chooses the roof bracket structure to build the power station, because it uses the roof of the building and idle space.

3, not all buildings can install photovoltaic systems

Some of the roofs are too narrow to find space to build photovoltaic squares. Others are blocked from getting the sunlight they need to generate enough energy.

While there are technologies like shadow optimizers and tracking axes to mitigate these issues, they can only improve some projects' revenue.

If you don't have a place to put solar panels, then developing a photovoltaic system will be a real challenge. At present, photovoltaic carport and photovoltaic sunlight room are relatively mature cases of photovoltaic building combination.
