What Is Bess Battery Energy Storage System?

Scenery complementary street light accounts for 41% of the proportion of the completed street lamp, accounted for 33% of the length of the road lighting have been completed, we can calculate a year it can power saving 500000 KWH, can save 186 tons of standard coal, 439 tons of carbon dioxide emissions, less reduce sulfur dioxide emissions 56 tons, reduce carbon 21 tons, environmental effect, presumably scenery complementary street lamp price is very expensive. Don't look at it, however, so energy conservation and environmental protection, in the aspect of building scenery complementary street light is not so expensive. With 10 years of investment, for example, if on the way to a certain city about 40 scenery complementary street light, need to install the required investment cost is slightly higher than that of traditional street lamp, but new energy scenery complementary street lights maintenance is 37% of the ordinary street lamp, 10 years, street construction, operation cost, new energy scenery complementary street lamp will be 33% lower than that of ordinary street lamp. Therefore, prices are still very relevant scenery complementary street lamps, and with the maturity and development of scenery complementary street lamp technology, construction scale in street lamp the proportion will gradually increase, and in the face of conventional energy decreases, and need to improve for renewable energy utilization, will be large-scale application of renewable energy sources such as solar energy, wind energy, technology, the natural scenery complementary street lamp price also will decline.

solar panel manufacturers - — Guangdong energy technology co. , LTD. For different types of photovoltaic system, the overall design goal is different. For grid photovoltaic systems, all work is focused on the whole photovoltaic power station output the maximum amount of electricity throughout the year to the grid. Therefore, the design is the overall goal of the energy loss minimum, so that pv systems throughout the year can achieve maximum power. For off-grid system independently, however, due to the application of photovoltaic system associated with the local meteorological conditions, the same load applied at different locations, the required capacity is also different. Pv systems throughout the year can get the biggest generating capacity is usually not the best choice. At the same time, the cost of photovoltaics are still relatively high, thus to build a reasonable perfect off-grid pv system, must carry out the optimal design of science, make the off-grid pv system can completely meet the demand of load, and can achieve the minimum capacity of photovoltaic module and storage battery, achieve the best combination of reliability and economy. Hybrid pv systems are basically used for off-grid power supply. Photovoltaic power generation system with wind turbine hybrid photovoltaic system is relatively high due to the cost of photovoltaic power generation. In order to reduce costs, ensure the quality of power supply, the optimized design in the right position, give full play to the complementary advantages of the solar and wind power. Therefore, in the design, the proportion of photovoltaic power generation and wind power should be reasonable, in order to make up for the inadequacy of single energy.
in order to improve power supply reliability and reduce the system cost.
in the diesel engine for standby power pv/diesel hybrid systems, should give full play to the capacity of photovoltaic system, was launched only winter solar radiation is lower as supplementary power diesel engine. This requires strict optimization design, the rational allocation of photovoltaic system, diesel engine power and battery capacity.

solar energy is an inexhaustible nature, an inexhaustible, pollution-free green energy, but it has the characteristics of randomness and intermittent. It is estimated that the earth each year about 7 x 1017 kilowatt-hours of energy from the sun, land for about 1 every year. 3 x 1016 KWH of solar energy. Due to the latitude and longitude of different parts of the earth, the Chinese average sunshine time and amount of sunlight in different areas of the difference is very big. China's average sunshine amount in 2. 6 KWH/m2 to 6. Between 4 KWH/m2, the sunshine amount between 1000 and 3300 hours of solar energy power supply system by solar modules, solar controller and battery ( Group) Composition. Inverter can also according to the actual need to be configured. Solar energy is a new clean and renewable energy, in people's life and work plays a wide role. One of them is to convert solar energy into electric energy. Divided into solar-thermal power generation and photovoltaic solar power. In general, solar power generation refers to the solar photovoltaic power generation, it has no moving parts, no noise, no pollution, high reliability, etc, in remote areas of communication power supply system has a good application prospect.

solar street lights and solar garden lights in the storage battery charging and discharging control is very important, mainly by the solar controller to control the implementation.
1, avoid transition charge high-energy battery charging current is twice that of an ordinary battery, large current charging are available, and can in the limited time in the day will be filled with battery. When battery monomer voltage reached 2. 25 v, voltage limit of 2. When 40 v, if it easy to form large current charging the battery still water loss. Therefore, require battery arrived at set of charging voltage, can automatically convert ChengJuan flow ( Small current) The control voltage precision of charging, charging for & plusmn; 0. 1V。
2, over discharge protection under the condition of different depth of discharge battery operating life spans are not the same. After the battery over deep discharging will form a permanent damage. In order to ensure the use of the storage battery become old, yea, should avoid deep discharge, when the battery voltage drops to a discharge point should be timely block load, continuous light. Discharge cut-off voltage shoulds not be too low, for single cells is about 1. 80 - 1. 85V。 Battery intermittent discharge, the voltage will gradually rise, finally can arrive in 2. About 2 v. Protection circuit is action, it is necessary to ensure the battery does not automatically restore discharge before without charge from the start.
3, temperature compensation control points is as the environmental temperature and battery voltage changes, so the solar energy lamp system should have a reference voltage by temperature control. When the temperature of the battery in T1 = between 15 ℃ and 35 ℃ T2 = without temperature compensation, but when the temperature is not in the range demand according to the type ( 1) Determine the float charging voltage UF = UFO + ( T- T0) C type, ufos and T0 datum of voltage and temperature, respectively; C for voltage temperature coefficient. 【 The above content of the solar street light for you publish 】
