Solar photovoltaic modules must meet the following requirements.
(1) It can provide sufficient mechanical strength, so that the solar photovoltaic module can withstand the stress caused by shock and vibration during transportation, installation and use, and can withstand the impact of hail.
(2) It has good sealing performance, which can prevent the corrosion of solar cells from wind, water and atmospheric conditions.
(3) It has good electrical insulation properties.
(4) Strong anti-ultraviolet ability.
(5) The working voltage and output power are designed according to different requirements, and a variety of wiring methods can be provided to meet different voltage, power and current output requirements.
(6) The efficiency loss caused by the combination of solar cells in series and parallel is small.
(7) The connection between solar cells is reliable.
(8) Long working life, requiring solar photovoltaic modules to be used for more than 20 years under natural conditions.
(9) Under the condition that the foregoing conditions are met, the packaging cost is as low as possible.
