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
Q:I want to install a full set of domestic solar heating equipment does not know how much money to spend, please.
According to the annual use of 280 square meters of construction area of the average daily consumption of 11 square meters, energy saving rate of more than 50% of the total energy consumption of more than 11 square meters. Cost: 38000 yuan (excluding heating part); system design life: 20 years; saving ratio: 280 square housing annual use of wall mounted gas boiler is about 3000 cubic meters of natural gas per cubic, an average of 2.2 yuan, a total of 6600 yuan.
Q:Solar power generation system installation which precautions, ah, there is a need for special attention
Pay attention to the basic power calculation is not enough! The reality is not up to
Q:Solar photovoltaic system
Analysis of economic benefits: 50kW distributed photovoltaic PV power plant total operating period: 25 years of this project on average generating capacity: the annual average generating capacity of 200kWh: 73000kWh, 25 years of total power: 1825000kWh residential electricity price: 0.55 yuan /kWh local coal-fired power benchmark price: 0.44 yuan /kWh (the case): Total investment the total investment of about 450 thousand yuan, equivalent to 9 yuan / watt.
Q:Solar PV systems
Fifth distributed photovoltaic power generation implementation of self occupied, power over the Internet, the nearest consumptive, power regulation, operation mode. The power grid enterprise uses advanced technology to optimize the operation and management of power grid, and provides the system support for the distributed photovoltaic power generation operation. To encourage investment business entities with the same power supply area of the power users in power grid enterprise cooperation in a variety of ways to achieve the nearest consumptive distributed photovoltaic power generation.
Q:Solar power generation system suitable for home, how much is the cost of a set?
The use of solar power system has many parts, have the power of this parameter, he said 500W1000W is a parameter which kind of accessories, and electricity related degree is large, panels, solar power systems, accessories, solar panels for electricity generating capacity of the inverter board and the two parts of the largest correlation under normal circumstances, the board 1000W day power of 4
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: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:What are the devices needed for PV systems?
Solar cell array. The solar cell array is composed of a solar cell composite plate and a square bracket. Because the single voltage of solar cells is generally low, so usually they are connected in parallel and series solar panels have practical value, as an application unit, and then according to the power requirements of a plurality of application unit series and parallel composition of solar cell array. Solar panels (some semiconductor materials, mainly polysilicon and silicon and amorphous silicon, through a certain process to assemble) is the main component of the solar photovoltaic system, the highest value is also part of the solar photovoltaic power generation system. Solar panels in the light of the circumstances, the battery absorbs light energy, the two ends of the battery appears to be the accumulation of different charges, that is, the light generated voltage, which is the "photoelectric effect". Under the action of the photoelectric effect, the electromotive force is generated at both ends of the solar cell, and the light energy is converted into electric energy.
Q:What are the components of the solar photovoltaic system?
Frame: aluminum alloy frame with high strength, strong resistance to mechanical impact. Is also the most valuable part of home solar power. A device for converting direct current into alternating current. Since the solar cells and batteries are DC power, while the load is AC load, the inverter is essential. The inverter can be divided into independent operation inverter and grid connected inverter. The independent operation of the inverter is used for the independent operation of the solar cell power generation system, for independent load power supply. Grid connected photovoltaic power generation system for grid connected operation. The inverter can be divided into square wave inverter and sine wave inverter according to the output wave type. The square wave inverter has the advantages of simple circuit, low cost, large harmonic component, and the utility model can be used for a system with a few hundred watts and a low harmonic requirement. Sine wave inverter is expensive, but can be applied to various loads.
