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?
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.
Q:Solar power generation system suitable for home, how much is the cost of a set?
Configuration of a household solar power system is about ten thousand to $twenty thousand
Q:Rooftop solar system
Recommended to buy solar water heater price per price in the 150-180 yuan, including in accordance with the material and other costs, buy a good look at whether there is a reliable after-sales
Q: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 low
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?
To choose the right, we must first understand the composition of the system and the core of the power generation. Solar power system consists of solar panels or solar module, inverter, bracket, distribution box, cable and other accessories. The core components are solar modules and inverters, which directly determine how much electricity is generated and how many years to come. 5KW system, in the summer when the maximum amount of light radiation can be issued 23 days a day or so.
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:How to calculate the income of photovoltaic system
Hypothesis: 1 my peak electricity price of 1 yuan / degree, the flat price of $0.7 / degree, the local coal desulfurization unit benchmark price of 0.4 yuan / degree. 2 my home at noon to 1 points solar power generation of 90 degrees, power consumption of 40 degrees; in the afternoon from 5 to 6 solar power generation of 10 degrees, power consumption of 60 degrees. Results: 1 according to the total solar energy power generation and the total energy consumption calculation two times my solar power electricity is 100 degrees, 100 degrees, more than electricity difference is zero; so I save electricity 85 yuan, receive subsidies 35 yuan, the total revenue of 100kWh * [(1 + 0.7) /2 + /kWh = 0.35 yuan) 120 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
