Benefits of Solar Power:

Now is a great time to go solar and harvest the power of the sun. Here is our top ten list of the benefits to installing solar power:

1, When installed, solar energy is free – no resources are consumed
2, Help to lessen our dependence on heavily polluting coal power stations
3, Fossil fuels can't last forever, future generations will appreciate the effort
4, You are gaining energy independence - add battery backup power for even greater energy security
5, The cost of electricity is only going to rise – insure against that rising cost
6, Quality solar power and water adds value and appeal to your home
7, Solar PV systems are easily upgraded in future - aim to make your house a net energy producer!
8, Solar panels offer a long lifetime of low maintenance service, maybe 30-40 years
9, Your friends will think you're great!

10, You'll feel great for doing your bit for the environment!

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?
Solar cell array. The solar cell array is composed of a solar cell composite plate and a square bracket. Because the single voltage of solar cells is generally low, so usually they are connected in parallel and series solar panels have practical value, as an application unit, and then according to the power requirements of a plurality of application unit series and parallel composition of solar cell array. Solar panels (some semiconductor materials, mainly polysilicon and silicon and amorphous silicon, through a certain process to assemble) is the main component of the solar photovoltaic system, the highest value is also part of the solar photovoltaic power generation system. Solar panels in the light of the circumstances, the battery absorbs light energy, the two ends of the battery appears to be the accumulation of different charges, that is, the light generated voltage, which is the "photoelectric effect". Under the action of the photoelectric effect, the electromotive force is generated at both ends of the solar cell, and the light energy is converted into electric energy.
Q:Solar photovoltaic system
State subsidies for distributed PV policy: distributed generation price subsidies by 0.42 yuan / kWh (subsidies for a period of 20 years), distributed photovoltaic power generation system of power grid, power grid enterprises in accordance with the local coal-fired power by electricity (0.44 yuan /kWh) acquisition.
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: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 how to choose?
Solar power generation technology is now very mature, the most important choice is to generate sufficient power, stable operation, reliable warranty and after-sales service.
Q:Solar power generation system installation which precautions, ah, there is a need for special attention
Solar power system consists of solar panels, solar controller, battery, inverter and other load. Solar power system installation note has the following 1, the battery plate array need to consider the installation azimuth angle, tilt angle. 2, to avoid blocking between the panels. Including the surrounding buildings (poles, building eaves, etc.). 3, stent placement stability and firmness. 4, the distance between the line and the bus box location. Try to walk a short distance and average. 5, related accessories to meet the system requirements (such as wiring column, with wire diameter etc.). 6, the terminal should be firm, to prevent the virtual connection or disconnection.
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.
