What are the drawbacks of installing rooftop solar photovoltaic systems?
With the rapid development of photovoltaic technology, many households have installed photovoltaic systems on their rooftops. However, what are the disadvantages of installing solar rooftop power generation systems?
The concept of installing rooftop solar photovoltaic systems is very simple. Most installations involve drilling holes to mount solar photovoltaic brackets, and then placing the solar panels on top of these brackets. This typically requires the roof to face east or west so that it can follow the sun's path throughout the day. Additionally, if there are nearby obstructions causing shadows on the photovoltaic brackets, it can lead to energy loss in solar power generation.
When houses were built many years ago, the roofs were not designed to bear the weight of solar power systems. Installing a relatively heavy solar photovoltaic system on the roof could easily lead to overloading, causing damage to the roof. Therefore, if a rooftop photovoltaic bracket system is to be installed, proper load calculation must be done in advance.
Drilling holes in the roof also carries the risk of damaging it. When installing rooftop solar photovoltaic systems, drilling spaced holes throughout the roof can weaken the underlying structure, creating the potential for leaks in the future. If a leak occurs, it may take weeks, months, or even years for the homeowner to notice it. Additionally, mold and other risks may arise, leading to further costs.
