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:Home solar heating products can not mature?: Solar panel power generation, then the proposed size of the proposed group, mainly the power substation and storage of electrical equipment is very expensive, the highest conversion rate in the 17%-20% efficiency is very low, not as good as plant photosynthesisNow the national clean energy, photovoltaic power generation policy is more than 10kW can be free of charge, but the price of electricity recovery is very low, cumbersome procedures.Buy solar water heaters, the first proposal to consider the local climate, installation conditions, economic prices and durability

Q:How to make better use of solar energy: The first stage (1900~1920 years) at this stage, is still the focus of solar power plant solar energy research in the world, but the spotlight by diversification, and began to use the flat plate collector and low boiling point device, gradually expanded, the maximum output power of 73.64kW, with the objective clear, cost is still high.

Q:As a new energy solar energy has attracted more and more attention has been paid more and more practical application at home and abroad, I really want to know what are the solar energy application is very hope that we put forward their own views and even science fiction book that I want to do research on solar solar energy market in the military and political life etc.: Power utilizationClear new energy in the future large-scale use of solar energy is used to generate electricity. There are many ways of using solar energy to generate electricity. Has been used mainly in the following two.1, the light - heat - electricity conversion. Heat generation by solar radiation. The utility model is characterized in that the heat energy absorbed by the solar collector is converted into the working substance steam, and then the steam driven turbine drives the generator to generate electricity. The first process is the conversion of light and heat, and the latter is the conversion of heat and electricity.2, optical electrical conversion. Its basic principle is to use the photovoltaic effect to convert solar radiation directly into electrical energy.

Q:Buy solar water heater mainly look at what?: Buy solar water heater mainly look at what?CDR | outside browse 976Recommended 2016-07-10 11:21:15 best answerBuy solar water heater, the four attention"First, the three components is the key to buy solar water heaters, analysis of production strength is very important. The strength of the enterprise is reflected in many places, and the key components are the most important. Three components include: vacuum tube, insulation layer and liner. The vacuum tube and the insulation layer determine the temperature rise and thermal insulation of the water heater, and the inner liner determines the life of the water heater, so these three parts are the core of the solar water heater. First, in accordance with national standards, the vacuum tube must be relatively high cost of high borosilicate 3.3 glass material, so as to ensure its light transmission and compression, anti-corrosion, impact resistance.

Q:30MW solar thermal power plant total investment: 0MW total investment in solar thermal power plants:Solar thermal power generation units at home and abroad to invest 1.5~3 yuan /kW range, so 30MW power plant is currently estimated to invest 5-9 billion yuan RMB.

Q:Solar energy application technology, there is no prospect: However, from a policy point of view, there is no industry like solar energy so much attention by the country. Compared with the traditional fossil energy, solar energy has obvious advantages. Therefore, the prospects are good.In a word, the future is bright, the road is tortuous!!

Q:Solar electric vehicle charging device: Performance characteristics of solar charger for electric vehicle:1 suitable for 36V, 48V configuration of the electric vehicle voltage conversion2 unique electric vehicle battery repair function, because of its continuous battery to supply electric power to prevent and remove the battery plate sulfide, recovery of battery capacity, prolong battery life, reduce the economic burden of the users.3 using the level of intelligent tracking system, the use of a new track concept, to achieve a day in the system of the sun's automatic tracking, improve the photoelectric conversion rate, increase the power supply to the battery.4 unique overvoltage protection technology to ensure the safety of charging equipment.

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:PV solar products market sales: According to the State Administration of taxation policy released last year, from October 1, 2013 to December 2015 3l, according to the 3% levy rate calculation. In Takamatsu as an example, if a month sales of 30 thousand, that he should pay the tax is 30 thousand x 3% x 50%=450 yuan.Residents issued 1 kwh of electricity, the state subsidy of 0.42 yuan; the national standard for the purchase of electricity from the desulfurization of residents with endless self generating electricity, the price is $0.42 per degree. To install and use a set of distributed photovoltaic power generation system with an average of 1 kilowatts of installed cost about 10 thousand yuan, if the 8 kilowatt system daily generating capacity of 30 degrees, 5 degrees every household consumption (no more than a price of 0.52 yuan), about 8 years to recover the investment

Q:Outdoor solar energy products, how can we do the process of IP65 level, the design of the water which should be noted that what? Beg enlighten heroes!: Sub form to be simple, the need to seal the place where the seal can not add the province.Second, is the protection of components, internal structure should pay attention to water and diversion, it is best not to enter the water.
