Features of Complete Solar System
Solar module:solar battery module(also called photovoltaic battery module)in series or in parallel according to the system requirements,the solar energy will change into electrical energy in the light of the sun and then output,it is the core component of solar photovoltaic system.
Controller: solar power controller is an important part of the solar power system, System of charging and discharging and load work automatically by its intelligent control and protection. Its performance directly affects the reliability of the system. Especially the battery life, overcharge or over discharge will be cause damage and even lethal damage for the battery.
Inverter: in solar photovoltaic power supply system, if it has the AC load, it is necessary to use the devices of the inverter. The direct current generated by solar modules or the battery release of DC into AC for load.
Battery:Stored up the electricity produced by the solar cell module produce,When illumination is insufficient or night or load demand is greater than the power produced by the solar cell module.Stored energy will be released in order to meet the load demand of energy,It is the solar energy photovoltaic system energy storage unit.Currently solar pv system commonly used is lead acid battery,For higher requirements of the system,Usually adopt deep discharge vrla battery ,deep discharge suction fluid type lead-acid battery,etc

- 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?
- 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: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.
- 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: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.
- 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 photovoltaic system
- To search and collect profit (in all spontaneous terms): the average recovery of funds on average generating capacity = * (distributed generation electricity subsidies + residential electricity price =200* (0.42+0.55) =194 were the first year of the recovery of funds = daily recovery funds *365=194*365=70810 yuan investment recovery period = total investment / average recovery of funds is about =450000/70810=7.06 years. 6.5 years 25 years average annual net income = recovery funds * (20 -6.5) + daily average generation price *365 * electricity days *5 years =70810*13.5+200*0.55*365*5=1156680 yuan
- Q:What are the devices needed for PV systems?
- Controller。 Device for regulating and controlling electric energy.
- 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: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.
