Solar power generation system suitable for home, how much is the cost of a set?
- Solar photovoltaic power generation is suitable for families but to look at your location and sunshine time, before the country without a policy or honest with general electric, energy saving is a national matter we the people pay so without savings
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.s
Rooftop solar system
- Now 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.s
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?s
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.s
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.s
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 currents
