Household photovoltaic power plants for the roof

This photovoltaic power generation the most important source of energy is the sun. In order to facilitate the generation, General installation according to the location of the house and select the best lighting direction. Regardless roof bungalows or buildings, lighting and the best place. The majority of people live on the top floor in the city do not have time to take care of the roof, it sitting there. It sounds very unfortunately - instead it idle, it is better to put it utilized self-built home photovoltaic power plants.

Household photovoltaic power plant requirements for the roof, the most important thing is to know Xiaoqi Cheng weight capacity, especially the top of the European spire house. Solar panels can not be directly shelving roof, only through the bracket. And the roof load capacity of the wind turbine inverter are different, there may be fixed to the phenomenon of regional overweight. Build power plants, we must first find out own shingle below the load-bearing walls or reinforced concrete load-bearing beams exact location and roof panels bearing parameters.

These data can be obtained by residential property, get this data, you can accurately know the roof plane load-bearing capacity of the regional distribution, and what needs to be installed solar panel bracket, where not directly binding bracket. Different power, different types of solar panel Battery weight of each type. Any the HL appliance station solar panel power is 3 kW, with an average weight of 25 kg each block. The roof of the outermost layer is not thick laminates, cracking, once the overload is not impossible.

In addition to the load-bearing, wind load capacity of the roof is also a need assessment an important indicator of one. Beijing in early March has just suffered the baptism of the eight winds, summer and autumn, the southern city of Typhoon destructive power is not really small. This is often most overlooked small problem, REN Kai in the interview he was repeatedly raised. Case of total destruction of the house is small, but not small local destructive action of the wind. Of solar charge controller installed on the roof and brackets also belong to the roof of the local, occasional high winds struck it is not impossible.

In addition, solar panels and brackets security risks can not be ignored. Today, for aesthetics, most of the roof of the house are curved plate group or triangular pressure coefficient inconsistencies. Before installing the power plant, it should find the property inquired about the wind load capacity, then appropriate adjustments to the position of the solar panel. If you do not live on the top floor, then you can think about other places, such as the small yard or improvement of the balcony.

REN Kai converted house will be open on the second floor and the third floor balcony became enclosed sun room, glass selected amorphous silicon thin film batteries to power generation material, building integrated power mode. He felt that the possibility of power compared to the rooftop, sun room mode is more suitable for the majority of households in the city. As long as the glass part, if light can be converted into such power generation mode. However advantages and disadvantages: direct sunlight on the roof of a more vertical angle, the average conversion efficiency of 15%, while 7.5% of the conversion rate of the glass wall.
