Q:Rooftop solar system
Solar panel power generation, then the proposed size of the proposed group, mainly the power substation and storage of electrical equipment is very expensive, the highest conversion rate in the 17%-20% efficiency is very low, not as good as plant photosynthesis
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
Fifth distributed photovoltaic power generation implementation of self occupied, power over the Internet, the nearest consumptive, power regulation, operation mode. The power grid enterprise uses advanced technology to optimize the operation and management of power grid, and provides the system support for the distributed photovoltaic power generation operation. To encourage investment business entities with the same power supply area of the power users in power grid enterprise cooperation in a variety of ways to achieve the nearest consumptive distributed photovoltaic power generation.
Q:What are the devices needed for PV systems?
Battery pack. The utility model is used for storing the electric energy generated by the solar array when illuminated by the light and can supply power to the load at any time. In the grid connected solar power generation system, the battery can not be added
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: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: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?
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.
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
