Q:What are the main features of solar photovoltaic systems
Compared with the commonly used thermal power generation system, the advantages of photovoltaic power generation:No danger of depletion; safe and reliable, no noise, no pollution, absolutely clean (pollution-free); not subject to geographical distribution of the resources, can take advantage of the building roof; for example, areas without electricity, and complex terrain area; no fuel consumption and the erection of transmission line can be on-site power supply high quality energy;; users emotionally receptive; the construction period is short, get energy to spend a short time.
Q:Solar PV systems
Fourth administrative department of energy of the State Council is responsible for the distributed photovoltaic power generation planning guidance and supervision and management; the local competent department of energy under the guidance of the State Council department in charge of energy, to supervise the construction of distributed photovoltaic power generation planning, the area; the national energy administration agencies shall be responsible for the supervision of the area of distributed photovoltaic power generation planning and policy implementation, network operation, the market fair and safe operation.
Q:How about the price of solar power generation system
At present, the domestic solar power generation system installed capacity, investment is also different, generally less than 30 thousand yuan in the 3KW, 5-10KW more than $9 per watt, for example, about 8KW or so. Solar power generation system consists of components, inverters, stents and other components, components can be found Yingli, Trina these, inverter Hefei sunshine, Foshan de nine for you to answer.
Q:What are the devices needed for PV systems?
Controller。 Device for regulating and controlling electric energy.
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: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: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:What is the system voltage of solar panels
System voltage refers to the number of solar panels composed of a solar power generation system, the maximum DC voltage of the power system.
Q:Solar power generation system suitable for home, how much is the cost of a set?
As a new type of clean energy, solar energy has been in a state of high cost due to the purification technology and the price of silicon, but it can not be used in the case where there is no way to connect with electricity
Q:What are the advantages and disadvantages of small-scale solar power generation system?
There are intermittent and random ground application, power generation and climatic conditions in the night or rainy days have little or no power; lower power density, under standard conditions, the solar radiation intensity on the ground received for 1000W/M^2. Large scale use, the need to occupy a larger area; the price is still more expensive, for conventional power generation 3~15 times, the initial investment is high.
