The working principle of solar photovoltaic products

sunlight as the energy, solar photovoltaic products by solar modules to accept solar radiation during the day, convert light energy into electrical energy, and under the management of the controller to the battery charging, when used, the controller in accordance with the procedure set electrical energy is released from the battery to the power supply equipment. Equipped with inverter with protection device, can have the function to communication equipment power supply.

solar photovoltaic products including solar lamp of the bell, solar controller, solar flashlights and solar power generation system. Several problems about the customer care

, how to select solar lamp light source?

solar lamp with high efficiency, energy saving light source in general. Currently applied in solar lamp light source ( The light bulb) Mainly has high efficiency dc energy saving lamps, super bright LED lamp, electrodeless electromagnetic induction lamp semiconductor ( LVD) And low pressure sodium lamp ( 有限合伙人) And high pressure sodium lamp ( HPS） And so on. At present, a lot of solar energy lawn lamp choose LED as light source; Commonly used solar garden light and V dc LED energy-saving lamp as light source; Solar street lamps according to the need of the actual situation, can be in V dc energy saving lamps, low voltage sodium lamp, high-pressure sodium lamp, the infinite choices electromagnetic induction lamp and other light source.

no matter choose that kind of light source, power is directly related to its brightness and light source. The same light source, the greater the power, the higher the brightness; The smaller the power, the lower the brightness.

how long can, solar lamp sunny weather lighting?

solar lamp lighting duration can be set according to user requirements. For the same location, with the solar energy battery components and battery is directly related to the ratio of choice. , under the premise of the confirmation of the light source power to choose solar energy battery components and battery capacity, the greater the power to ensure that the longer the illumination time, shorten conversely. The standard system configuration generally should guarantee every day ~ hours of lighting.

, solar lights in this rainy weather can use how long?

solar lamp in the guarantee of continuous rainy day time can be used according to specific conditions and the requirements of customers for the design. Normally, in case of continuous wet weather, should meet not less than days ( ~ hours a day) The illumination time.

and how long is the service life of the main components of photovoltaic products?

solar modules, controllers, batteries, lighting light source is solar lighting products of four main parts, the service life of their respective reference in the following table
