Photovoltaic power generation is by physical action, the solar energy directly into electrical energy directly to the process, does not produce any pollution and noise in the middle. Photovoltaic module is the core component of photovoltaic power generation systems, photovoltaic inverter is to produce direct current into alternating current (ac) devices, also is the important components of power systems.
According to whether the power grid, can be divided into two types of access, off-grid and interconnection. Off-grid belongs to the independent power supply system, from the power supply network; And photovoltaic power grid is the grid application way. Now, grid are the major ways of using photovoltaic (pv) power grid and can be divided into the ground power station and distributed.
Off-grid system consists of photovoltaic module, controller, inverter, battery and so on several parts. Have sunshine power generation, and the electricity is stored in the battery, the output electricity back on.
General large hydropower station on the ground, installed on the ground of large area, direct power grid; General installation and distributed power station in the family or the roof of the industrial and commercial buildings, is relatively small, hooked up to the grid at the same time, also for the building electricity. This two ways, the government subsidy standard is also different.
- Q: What is the difference between photovoltaic products and solar energy?
- But in general, as many of the world's oil and gas production areas of political and economic instability, many governments are taking active measures to reduce dependence on foreign energy sources. Solar energy provides an attractive power generation program, and will not form a serious dependence on foreign energy. In addition, the increasingly serious environmental problems and fossil fuel power and political reasons of climate change risk formation, prompted the government to implement the aims to reduce carbon dioxide and other greenhouse gas emissions reduction strategy. Solar energy and other renewable energy sources contribute to the solution of these environmental problems.
- Q: How to choose a good use of solar energy
- Water capacity of water heaterAccording to the number of people, to determine the size of the solar water heater capacity, three of the family at least choose the volume of more than 100L, in general, the larger the size of the solar water heater tank, the better.Domestic solar water heaters to buy the first to determine the volume of solar water heaters. The general situation of the shower, according to the volume of 40-50L/ people to determine the volume of products to be purchased; the general bath needs about 35kg - 50kg hot water (45 degrees Celsius). Because solar non conventional energy in rainy days can produce hot water heater, so choose twice daily water consumption, the sunny hot water thermal storage to be used in rainy days. In the case of two consecutive days, you can choose to use dual-use photoelectric, to ensure all-weather, all year round hot water use
- Q: Solar products must be in the sun
- Other light sources can be used to meet the needs of the product (e.g., solar watches can be recharged by other light sources)
- Q: Product category and comparison of solar thermal utilization
- Why choose a new type of efficient flat plate solar water heater (device) system?In recent years, the use of solar thermal products in China has been rapid development. In the solar water heater manufacturing, use and market share, China has far ahead. However, due to the use of solar thermal products in domestic vacuum tube based, in full swing in the development of the industry, but also exposed a lot of worrying problems.
- Q: Solar energy products, that is, I would like to open a home solar products Daquan
- Photoelectric, two large blocks of light and heat, I think it will be a complete. But a lot of financial strength to do it
- Q: How to do a good job of solar water heater marketing?
- Two, energy saving (cost savings): the impact of solar water heater life components. About the use of solar water heaters for heating homes, can save daily for heating water electricity, gas costs 90%, can reduce household expenses, to the society, can reduce our province limited energy resources consumption, the energy and ancillary facilities for agricultural and industrial production, have greater social benefits.
- Q: What is the difference between the expensive solar energy and the cheap one?
- Cohesive light film vacuum tube is used their thermal power generation technology, positive negative light, heat, warming faster, higher water temperature, which is unique in the world (Himin patent, ultra cold polar tube, Antarctic expedition team designated products, 40 degrees below zero still out of hot water, hot water is not broken; they are equipped with low winter) the temperature of the water level sensor, accurate induction, automatic operation of the whole system, you don't have to worry about is not water ah, can bathe ah; not only that, once the hot water machine what, their customer service staff will serve you within 48 hours. This is not high price but not expensive, is the value for money, or even value for money?
- Q: What are the functions of the new vehicle negative ion solar charging humidifier?
- Brown vehicle negative ion solar charging humidifier, in addition to negative ions and solar charging function, but also can be used as car fragrance, you can add essential oils.
- Q: Solar panels with single crystal silicon or good thanks
- Single crystal or polycrystalline good?Many of my friends would ask is good or good crystal crystal, we many people buy just as ordinary lighting and small system to watch TV, to tell the truth this is really no need to care about the single crystal or polycrystalline, regardless of the need is a power is enough, two is the price is good!
- Q: Solar energy items in daily life
- Solar ice pad, solar panels, solar street lights, etc., are living in the solar green energy-saving products.
