Solar radiation
Provided that the photovoltaic power plant has a certain energy output, the amount of energy generated depends on the intensity of the light, and the amount of solar radiation is directly proportional to the electricity production of the photovoltaic plant. In other words, the more sunlight there is, the higher the electricity production will be.
How to install solar photovoltaic modules
If the lighting conditions in the same area are the same, but the tilt angle of the installed solar photovoltaic modules is different, the amount of solar radiation received by the photovoltaic panels will be different. The amount of radiation can be increased by adjusting the tilt of the photovoltaic panels or adding tracking equipment.
Depending on the solar lighting resources and the longitude and latitude of where the photovoltaic modulesare used, install the tilt of the photovoltaic panel according to the following conditions.
When the latitude is 0 to 25°, the tilt angle of the solar photovoltaic module is the same as the latitude.
When the latitude is 26 to 40° , the tilt angle of the solar photovoltaic module is latitude + (5 -10)°
When the latitude is 41-55°, the tilt angle of the solar photovoltaic module is latitude + (10-15)°
When the latitude is >55°, the tilt angle of the solar photovoltaic module The tilt angle is latitude + (15-20)°
Power attenuation of photovoltaic modules
Power attenuation of photovoltaic modules refers to the output power of photovoltaic modules as the lighting duration increases, followed by of a decreasing phenomenon. This is linked to the characteristics of the photovoltaic modules themselves, such as power attenuationance of modules caused by aging of photovoltaic modules, power attenuation of modules caused by destructive factors, etc.

Matching photovoltaic modules in series and parallel connection
Any series connection will result in current loss due to the current difference of the components; will cause current loss due to the current difference of the components. Voltage differences cause voltage losses;
Some components of photovoltaic power plant equipment are blocked by various factors, such as trees, dust, buildings. , etc. Some of the blocked components can easily cause hot spot effects and affect the power generation of the power plant. According to estimates, dust losses in power plants could reach 6%! According to the circuit principle, when the components areconnected in series, the current is determined by the smallest component. Therefore, if there is a shadow on a component, it will affect the power output of that component. Therefore, components should be cleaned and wiped regularly to reduce dust. Line losses are mainly line losses in the DC and AC circuits of the system. To use wires with good electrical conductivity, the wires must have sufficient diameter. No shortcuts are allowed in construction. When maintaining the system, special attention should be paid to the connection of plug-ins and the safety of wiring terminals.
