6 FAQs about [About the attenuation law of photovoltaic panels]
How to determine the attenuation rate of performance factors of PV panels?
To obtain the attenuation rate of performance factors, the experimental platform is used to test and record the power generation performance of PV panels, including output power, irradiance, voltage, current, etc. The output power curves of six dust pollutants under eight irradiance with five levels dust concentration are shown in Fig. 7. Fig. 7.
Does irradiance affect the attenuation rate of PV panels?
Combining the influence of irradiance on the attenuation rate of PV panels output performance indoor low irradiance dust accumulation simulation experiment, the saturation irradiance point of each pollutant is obtained and a DC-PCE theoretical model considering pollutant types, irradiance and dust concentration is established.
What is the relationship between density of mass and power attenuation?
By fitting the data, it is found that the relationship of density of mass satisfies P=P0 exp ( -km ), where P0 is maximum output power of the solar cell when the surface of the photovoltaic glass is clean, and k is the power attenuation coefficient.
Does dust affect power in photovoltaic modules?
It reveals the essence of the influence of dust on power in photovoltaic modules. Through optical and electrical experiments, it is found that transmittance has more explanatory power, because the reflectance decreases by about 1.1% in the range of density of mass from 0 to 10 g/m2. In comparison, the transmittance decreases by about 35.0%.
Does dust affect transmittance change of PV glass with different density of mass?
Transmittance change of PV glass with different density of mass was studied. The influence of dust on incident light is mainly the shading effect. The relationship between key parameters of PV module and density of mass was found. The essence of the influence of dust on the power of PV module was revealed.
