              1. Keep ventilation

              Regardless of the components or the inverter, the distribution box should be kept ventilated to ensure air circulation. For the components of the rooftop photovoltaic power station, it is important not to arrange the modules of the photovoltaic power station unreasonably in order to generate more power, which causes mutual shielding between modules and affects heat dissipation and ventilation, resulting in low power generation.

              2.Clean up debris around the photovoltaic power station in time

              To avoid affecting the heat dissipation of the photovoltaic power station, it is necessary to ensure that the around of photovoltaic modules, inverters, and distribution boxes are wide open, and if there are debris accumulation, clean up in time.

              3. Shade the inverter distribution box

              Inverters are generally ip65 protection grade, with a certain degree of wind, dust and waterproof.  However, when the inverter and distribution box work, they must also dissipate heat, so when installing inverters and distribution boxes, it is better to installed in shades and shelters. If it is installed in the open air, the inverter and distribution box must be protected from direct sunlight. Avoid overheating the inverter and distribution box and affect the power generation. 

              4.Regular inspection and cleaning is essential

              After the PV power station is built, the operation and maintenance can't be sloppy. Especially in the summer, it is best to conduct regular inspections to ensure that the PV power station has good heat dissipation and air circulation, remove all of weeds and obstructions that affect heat dissipation. Only in this way, the power generation and operation of the photovoltaic power station can be guaranteed.

              At the same time, if the photovoltaic panel is not cleaned for a long time, a large amount of dust will accumulate on the surface. Even after rain, dust will accumulate on the lower part of the photovoltaic panel because the installation Angle of the photovoltaic panel is not very big. Therefore, artificial cleaning is required. Rinse with water first, then wipe with a cloth mop. 

              Don't underestimate the maintenance work of photovoltaics. Take care of these details, and you'll be able to add up to an extra 1 kilowatt-hour of electricity each day. Over time, these increased electricity bills are considerable.
