As the input battery energy solar photovoltaic system unstable, it is generally required to configure the battery system to work, solar lamps is no exception, you must configure the battery to work. Lead-acid batteries generally, Ni -Cd batteries, Ni-H batteries, their reliability and system capacity options prices directly affect the system.
Choice of battery capacity generally follow the following principles:
First, to meet the night lighting under the premise of the energy as much as possible during the day a solar cell module stored, but also capable of storing electrical energy to meet the continuous rainy days night lighting needs. Battery capacity is too small can not meet the needs of lighting at night, the battery capacity is too large, while the battery is always in a state of loss of electricity, affecting battery life, while wastage. Battery selection also depends on the solar cells, the load is determined, let's be introduced in the system design.
?Load solar lighting products to energy-saving advantages, of course load to energy saving, long life. We generally use LED lights and 12V DC energy saving lamps and low pressure sodium lamp. At present, most lawn use LED as a light source, LED long life, it can reach more than 100,000 hours, low voltage, very suitable for use in solar lawn.
Garden lights generally use 12V DC energy saving lamps, energy-saving lamp voltage DC to DC, no inverter, convenient and safe.
12V DC energy saving lights generally use low pressure sodium lamps and low-pressure sodium lights high efficiency (up to 200LM / W). However, due to the low-pressure sodium lamps are expensive, use less.
?The shell we collected a lot of information on foreign solar lights, aesthetics and energy between the two, most have chosen to save energy. Exterior lighting requirements not high relative utility line. There are many manufacturers look very pretty, with stainless steel housing. But the performance in the end what? This brings us food for thought! Solar lighting system design a good product, the key lies in the system design, what is the rational system design? Let us first look at a few important factors which affect it!
