What is the working principle of solar street light1

Now the world's energy increasingly scarce, and the strengthening of environmental protection consciousness, the solar energy as a new source of green energy has been widely recognized, photovoltaic power generation technology has received the widespread attention, power controller used light volt generating system, in order to meet the needs of small and medium-sized power users, with independent solar street lamp system as an example, introduces the basic working principle of solar cells and lead-acid storage battery and characteristic, studied the tracking problem of maximum power point of solar battery, as well as the best charging the battery.

recharge converter designed a two stage method, combining the battery with a constant voltage, according to the engineering model of silicon solar cells, solar array is established the simulation model, and simulated the solar cell output characteristics of matrix, the two common disturbance observation method, tracking algorithm and incremental conductance measurement are simulated and compared, and understand the different algorithm to track the effect difference.

today completed the photovoltaic energy controller hardware design, the corresponding control procedures and algorithm using C language to write, and execute the lighting system of solar energy controller, the expected control function, load and discharge and perform overload protection, reverse connection protection and short circuit protection and other functions, and expected effect has been verified in practical application, the design the best solar street lamp, combined with engineering to deal with the key points that should be paid attention to in construction.

for guiding the design and engineering of solar street light has the very good reference value, now the application of the domestic solar technology, solar street light products of double advantage in protecting the environment and save energy appeared gradually, the application of solar street light is becoming more and more popular, the application of solar energy in the field of street lighting, gradually improve the urban public lighting engineering puts forward higher requirements, so it is necessary to continuously review the innovation and application.

as the solar street light is an important representative of solar photovoltaic applications received great attention, yet its application is limited by many conditions, such as limit the height of the street lamp itself the characteristics of the post is limited, the solar cell module installation method of limit is limited by environmental conditions and solar radiation conditions around, as a stand-alone photovoltaic solar street lights, solar street lamp design has its own characteristics.
