Q: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 price
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: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:What is the system voltage of solar panels
Solar panels are the most basic components of photovoltaic power generation systems and products. Its main role is to convert solar energy into electricity stored in batteries.
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: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 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: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:What are the components of the solar photovoltaic system?
Photovoltaic system is composed of solar cell array, battery, charge and discharge controller, inverter, AC distribution cabinet, automatic solar tracking system, automatic solar module dust removal system and other equipment. The equipment is in the light (either sunlight or other light generated by the light) case, battery to absorb the light, the two ends of the cell appeared heterocharge accumulation, namely "photo voltage", which is "photovoltaiceffect". Under the effect of the photovoltaic effect, both ends of the solar cell produce electromotive force, which converts light energy into electrical energy, which is an energy conversion device. Silicon solar cells are generally divided into monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells three
