Q:Solar PV systems
Third to encourage all types of power users, investment companies, professional contract Energy Service Companies, individuals as a project unit, investment and construction and operation of distributed PV projects.
Q:What are the components of the solar photovoltaic system?
TPT: on the back of the solar battery cover of fluorine plastic film is white, the sun has reflection function, so the efficiency of components increased slightly, and because of its high infrared emissivity, can reduce the working temperature of the component, but also conducive to improve the efficiency of the component. Of course, the fluorine plastic film with the first solar cell packaging materials required for aging, corrosion resistance, air permeability and other basic requirements.
Q:Rooftop solar system
Solar power generation, per square meter of power generation in 120W or so, the cost per square meter in 1500 yuan, the greater the area the lower the price
Q:I want to install a full set of domestic solar heating equipment does not know how much money to spend, please.
This area of solar heating system is divided into 4 parts: solar panels. Thermal energy water storage device. Thermal converter. Auxiliary heating wall. This system can be added with winter heating of buildings above 50% hot heat as a heat source for heating indoor floor heating systems, the spring and autumn three season can use gas or not using gas assisted heating (heat storage water tank can not increase the gas heating can be all-weather hot water).
Q:Solar photovoltaic system
State subsidies for distributed PV policy: distributed generation price subsidies by 0.42 yuan / kWh (subsidies for a period of 20 years), distributed photovoltaic power generation system of power grid, power grid enterprises in accordance with the local coal-fired power by electricity (0.44 yuan /kWh) acquisition.
Q:Household solar photovoltaic power generation system connected to the grid, how much money?
Sold to the power supply bureau 0.45 yuan once, the state subsidy fee of $0.42, a year issued 3000 kwh.
Q:Solar power generation system how to choose?
Solar power generation technology is now very mature, the most important choice is to generate sufficient power, stable operation, reliable warranty and after-sales service.
Q:How to calculate the income of photovoltaic system
Photovoltaic panels can only generate electricity, storage batteries need to match. The peak power output of photovoltaic panels = peak wattage X local sunshine time X efficiency coefficient of general domestic parts of the sunshine time is 4 hours (per day), the efficiency of PV system with battery is about 0.7. That is to say, 1000W system, the average daily electricity is about 2800WH (2.8 degrees) or so in accordance with the distributed PV subsidy of 0.35 yuan / degree, solar photovoltaic power generation more than the Internet how exactly?
Q:Solar power generation system installation which precautions, ah, there is a need for special attention
7, the battery terminal to be strong (10 million can not be short circuit) to pay attention to the polarity of installation, to avoid the explosion and fire. 8, the controller has the corresponding distribution protection measures. But the wiring process should also pay attention to prevent polarity reverse, short circuit, etc.. Avoid unnecessary trouble. Pay attention to the angle of placing and avoid the rain. 9, with inverter system, inverter connected to be connected to the battery positive and negative poles. 10, the construction site must be open, in the installation of solar cells can not be tall buildings or other things blocking the sun. 11, the controller needs to choose low loss, good stability, long life controller. When the installation is clear that the controller is a common negative or common cathode design, so that the entire system connection, installation help.
Q:What is the system voltage of solar panels
Solar panels (Solar panel) is composed of one or more solar cells to form a solar panel. A solar cell is a semiconductor device that converts light into electrical properties, which can convert solar radiation energy on its surface into direct current
