How To Identification the Quality of Solar Energy Battery Storage

Effect of Solar Energy Battery Storage


Solar energy as a new clean energy highly respected environmentalists, but when there is no sun, how should I do ? Solar energy battery storage case is to exist.PV off-grid power systems using the principle of photoelectric effect to convert solar energy storage battery to electrical energy generation system, usually consisting of solar modules, controller, battery, DC / AC inverter and other components.

 Plan, the role of the solar cell module is to convert solar energy into electrical energy and supplied to the load of work or to the solar energy battery storage pack; the role of the controller is a solar storage battery charge and discharge protection; battery for storing electrical energy; the role of the inverter the direct current is converted into alternating current. At night or rainy days, when the solar cell module does not work, powered by a battery pack to the work load.

Solar battery storage work can be divided into two recycling and the use of float. Often in frequent charging and discharging state, that is recycled; often in a state of charge of the float was used to make up for the loss of battery capacity due to self-discharge caused. PV system with VRLA batteries are recycled in a manner.


Best way to Identification the Quality of the Solar Energy Storage


By this standard, methods to identify, select solar absolutely wrong!Solar water heaters are large household durables, once it is possible to buy a home ten years does not change. Solar water heater materials, technology, technology is different from the life of 3 years, 5 years, there can be more than ten years. As on the roof of the hot water supply facilities, old and new solar energy does not affect the aesthetic appearance of the room, do not worry about upgrading problems. Therefore, from the perspective of the family investment, buy a life of more than 10 years of solar energy is the most cost-effective.

Valves, insulation, interior and accessories are the main factors affecting the life of the solar energy.Vacuum: vacuum tube solar water heater is the core component of its role is to absorb the solar energy into heat energy, and water pipe heating cycle. Quality vacuum tube directly determines the performance of the entire water heater.

Ordinary vacuum degree of vacuum is low, small power vacuum unit, exhaust time is short, the degree of vacuum only 10-1-10-2pa. Vacuum tube can not store heat for a long time, after a period of time in the outdoors, and thermal insulation performance is not pot. Coating technology backwardness, coupled with the technology, however, the emission ratio remains high, heat dissipation, the same sun day, half the amount of hot water are not high-quality solar energy.

 To make the battery system with high reliability, we must first correct choice of solar energy storage batteries, UPS batteries and communication in the design there are different: some have better battery cycle characteristics; some battery suitable promoter; some battery suitable for low-temperature environment; some battery suitable for low current discharge and so on.

In the selection of the solar energy storage batteries, the battery in the understanding of the various processes and the differences between the use is necessary, we must first fully understand the needs of users of the product itself. Such as back-up power system capacity needs, frequency of use, the use of the environment, the main purpose, service life, reliability, instantaneous discharge rate, rectifier solar energy storage batteries specifications and other relevant performance requirements.

We must understand the electrical performance of the solar energy storage batteries, including product design parameters (battery model, the appearance of size, rated capacity, rated voltage, the weight, the weight ratio of the energy, the volume ratio of energy, design life, the number of positive and negative plates sheet, positive and negative plates thickness ratio, the electrolyte density, type plates, grids and other materials), product electrical performance parameters, the actual life of the product, installation environment, the performance of different types and prices of different types of product warranty and so on.

December 26, 2014, the US electric carmaker Tesla released an updated version of the discontinued two years ago, the first generation model Roadster, the mileage of 644 km, 60% higher than the original.   Advances in battery technology to enhance the performance of the Tesla product, after Roadster Mileage is 393 km. Tesla CEO Musk said Tesla high-performance graphene battery, compared to the current capacity increase of nearly 70 percent. British scientists have invented graphene after 10 years, the application of the battery with great breakthrough. In early December, the Western media reported that Spain and the Spanish company Graphenano Cordoba University to develop graphene battery, a charging time of just eight minutes, can travel 1000 km. It is graphene researchers called "super cell." "We still understand the situation, the specific situation in Spain is proving such a battery, if this is confirmed, it is indeed a revolutionary c

When natural gas, coal, oil and other non-renewable resources, frequent emergency, energy is increasingly becoming a bottleneck for social development, the solar,wind and other renewable resources has become a new driving force for economic development. At the G20 summit, renewable energy issues, environmental issues will become the object of world leaders concerned, and as the organizer of China is more practical action to demonstrate its adherence to the concept of environmental protection,  solar power energy storage  technology also achieve a breakthrough, and further summit environmentally friendly match. Solar energy battery storage in the near future will occupy an important position in the world energy consumption, not only to replace part of conventional energy sources, and will be the subject of the world's energy supply. By 2030, renewable energy in the total energy mix accounted for more than 30%, while the proportion of solar battery storage in the world's tota

In addition, energy storage research also has multiple problems, such as foam cells, flow batteries to a variety of chemical materials, no one knows which technology will attract the most funds and research heat. Lux Research reports that the energy storage investment of more than 40 billion US dollars,  such as  solar power generator  and wind power,  the development of next-generation batteries, non-lithium-ion battery startups in the past eight years, an average of only 4 million funds, Tesla investment in lithium-ion battery factory Gigafactory invested 5 billion US dollars . R & D new battery material threshold is very high, just to build a small production line to study the details into production, it is necessary to 500 million US dollars, car manufacturers may also take several years to test the new battery system before deciding whether to purchase, if Your company has only $ 5 million in capital a year, making it hard to invest $ 500 million in manufacturing.
