Solar Lighting Manufacturers, For the design of solar lamps, success and failure often depends on the charge and discharge control circuit success and failure. There is no good performance of a charge and discharge control circuit, it is impossible to have a good performance of solar lamps. Charge and discharge controller must have the following characteristics: 1, anti-charge control 2, anti-overcharge control 3, anti-over discharge control 4, temperature compensation. 3, solar batteries As the solar photovoltaic power generation system input energy is very unstable, so the general need to configure the battery system to work, solar lighting is no exception, you must configure the battery to work. Generally there are lead-acid batteries, Ni-Cd batteries, Ni-H batteries, their capacity selection directly affect the system reliability and system prices. The choice of battery capacity generally follow the following principles: first in the night to meet the premise of lighting, the daytime solar cell components as much as possible to store the energy, but also to be able to store to meet the continuous rainy night lighting needs. Battery capacity is too small to meet the needs of night lighting, battery capacity is too large, on the one hand the battery is always in a state of loss, affecting battery life, while causing waste. The choice of battery is to look at the solar cell, the load to determine, this aspect in the system design for the introduction. 4, the load of solar energy products to energy saving and environmental protection for the advantage, of course, load to energy, long life Generally use LED lights and 12V DC energy saving lamps and low pressure sodium lamps and so on. At present, most of the lawn light selection of LED as a light source, LED long life, up to 100,000 hours, the working voltage is low, very suitable for use in solar lawn light. Garden lights generally use 12V DC energy-saving lamps, LED lights, DC energy-saving lamp voltage for the DC, no inverter, convenient and safe. Street lights generally use LED lights, low pressure sodium lamp, low pressure sodium lamp high luminous efficiency (up to 200LM / W), but because the price of low pressure sodium lamp is relatively expensive, with less. 5, solar lighting shell between the beautiful and energy-saving between the two are generally selected energy-saving. Lamp appearance requirements do not be very high, relatively practical on the line. At present there are many manufacturers look very beautiful, the option with stainless steel shell. 6, solar lighting system design a good solar lighting products, the key lies in the system design, how is a reasonable system design? First, look at the impact of the system several important factors, 1, latitude, 2, solar square surface of the total annual radiation, 3, the longest day without sunshine, 4, daily power consumption, 5, the average daily peak sunshine Hours. Imagine: if the solar cell charge less than the daily discharge will happen? If continuous for several times, http://www.cn-solargardenlights.com
