Advantages of rooftop photovoltaics

Advantages of photovoltaics on a roof :

1) Green energy. The integration of solar photovoltaic buildings produces green energy, which is the application of solar energy production, and will not pollute the environment. Solar energy is the cleanest and free, and there are no ecological side effects in the process of development and use. It is also a kind of renewable energy, which is inexhaustible and inexhaustible.

(2) No possession of land. PV arrays are generally installed on passive roofs or exterior walls without additional land ownership, which is particularly important for urban buildings where land is expensive; summer is the peak season for electricity consumption and happens to be the period when the amount of sunlight is the largest and the PV system produces the most power, which can play a role in peak regulation of the electrical grid.

(3) The integrated solar photovoltaic building technology adopts a grid-connected photovoltaic system, which does not need to be equipped with a battery, which saves investment and is not limited by the state of charge of the battery, and can make full use of the electricity that produced by the photovoltaic system.

(4) Play the role of energy saving of the building. The photovoltaic array absorbs solar energy and converts it into electricity, which significantly reduces the overall outdoor temperature, reduces the wall heat gain and the cooling load of the indoor air conditioner, so it can also play a role in building energy conservation. Therefore, the development of solar PV building integration can "save energy and reduce emissions."

Are rooftop solar panels harmful to the human body?

Rooftop solar projects, currently in developed countries, the United States, Germany, Japan and Australia have more than 100.000 sets of installations. If there is a breakdown, national counterparts are not allowed.

The solar panels are of static energy generation and the inverters and other devices comply with the relevant safety and electromagnetic compatibility regulations. Unless there is a fire and other special conditions, the AC and DC are not disconnected in time and the firemen continue the roof or there is a risk of electric shock, but there are also new regulations and installation method for protection.

Overall, regular manufacturer solar roof products are installed by qualified personnel according to specifications, without physical damage.

Are solar panels expensive?

In fact, PV plants are divided into off-grid and grid-connected systems. The most common is a grid-connected system, a system that is integrated into the grid and the electricity produced by the photovoltaics can be loaded into the grid without having to install batteries. Off-grid systems only need batteries During the day, electricity generated by photovoltaic plants is stored in batteries for emergency situations. This system is often used in applications such as non-electric areas, remote mountainous areas, islands and street lights.

Study confirms PV inverters should operate fault-free for around 15 years
