What are the advantages and disadvantages of small-scale solar power generation system?
- Solar energy inexhaustible, the earth's surface to accept the solar radiation energy, to meet the global energy demand 10 thousand times. As long as the installation of solar photovoltaic systems in the world's 4% deserts, the power can meet the needs of the world. Solar power is safe and reliable, does not suffer from the energy crisis or fuel market instability impact; solar energy everywhere, to the nearest power, do not have to avoid long distance transportation, long distance transmission line loss; solar energy without fuel, the operation cost is lows
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 prices
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
Solar PV systems
- Second distributed photovoltaic power generation refers to the user in the vicinity of the site or the construction of the operation, to the user side of the spontaneous use of their own, the excess electricity and the balance of the distribution network system for the characteristics of the photovoltaic power generation facilities.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
How about the price of solar power generation system
- Photovoltaic power generation system can not buy cheap, cheap product quality is not good to use expensive. Photovoltaic power generation system can be used to invest in financial products, general household photovoltaic system 7~9 can recover the cost of power system can be used for more than 25 years, 25 years after the power attenuation of about 20%, if the poor quality of the products are generally 2~3 years can be reduced by 20% and must keep their eyes open several more formal manufacturers so when buying light V system, quality quality assurance production factory.s
Solar power generation system how to choose?
- Inverter in the northwest power plant used more, but the Northwest Power Plant aunt groups of regular cleaning, and northwest power station construction in the warm sun where no human habitation, not what influence the efficiency of the system. Micro inverter system is more suitable for villas or single family houses, but the price is more expensive than the centralized inverter, such as Yu APS system efficiency of 95.5%. The United States is the best enphase, but the price is higher than 50%, the individual feels more than the amount of power generation, to buy domestic energy can be enough.s
I want to install a full set of domestic solar heating equipment does not know how much money to spend, please.
- Save 50% equivalent to an annual savings of more than 3300 heating projects; water consumption in accordance with an average of 200 liters a day, remove the winter has been deducted 120 days, the remaining 240 days probably with hot water total: 48 tons, natural gas energy is calculated according to the cost of the cheapest words per ton of hot water heating costs 15 yuan, annual water savings of 720 yuan. Two of the total savings of 4000 yuan, according to the energy prices coefficient is estimated at less than 10 years to recover the full investment, another ten years of savings more than 40 thousand yuan.s
