1, what is distributed photovoltaic power generation?
Distributed photovoltaic power generation refers specifically to the use of photovoltaic modules, the direct conversion of solar energy into a distributed power generation system. It is a new type, with broad prospects for the development of comprehensive power generation and energy use, it advocates the nearest power generation, near the grid, the nearest conversion, the nearest use of the principle, not only can effectively improve the same size photovoltaic power generation capacity, Effectively solve the power in the boost and long-distance transport in the loss of the problem.
2, the benefits of photovoltaic power generation?
Economic and energy saving: the general spontaneous use, the excess power can be sold through the national grid to the power supply company, when the power supply from the grid, since the savings can also get subsidies;
Thermal insulation: in the summer can be insulated cooling 3-6 degrees, winter can reduce heat transfer;
Green environmental protection: distributed photovoltaic power generation projects in the power generation process, no noise, there will be no light pollution, there is no radiation, is the true sense of zero emissions, zero pollution of static power generation;
Beautiful personality: the architecture or aesthetics and photovoltaic technology perfect combination, so that the whole roof looks beautiful atmosphere, strong sense of science and technology, and enhance the value of the property itself.
3, the roof is not south of the words, is not it can not install photovoltaic power generation system?
Can be installed, but the power generation is slightly less, according to the direction of the roof power generation is subject to change. The words of the south are 100%, and it may be between 70-95% of the east and west, and 50-70% in the north.
4, need to control their own hands every day?
Completely unnecessary, because the system monitoring is fully automatic, it will start their own off, no need to manually control.
5, I sell electricity and how to get the benefits of subsidies?
Before the network, the power supply bureau needs you to provide the bank card number, so that the local power supply station monthly knot / every month knot once; grid will be signed with the power supply company power purchase agreement; and network, the power supply bureau will take the initiative to settle with you.
6, light intensity is my photovoltaic system power generation?
Light intensity is not equal to the local PV system power generation. The difference is that the power generation capacity of the PV system is based on the local light intensity, multiplied by an efficiency factor (performanceratio), the actual use of photovoltaic power generation system, the efficiency of the system is generally 80%, close to 80% System is a relatively high quality system. In Germany, a better system could achieve 82% system efficiency.
7, rainy days or cloudy words on the power generation impact?
Will be affected. Power generation will be reduced, because the light time is reduced, the light intensity is relatively weakened. But we measured the average annual electricity generation (such as 1100 degrees / kW / year) is able to achieve.
8, rainy days, photovoltaic power generation is limited, my home will not be enough?
This worry does not exist, because the photovoltaic system is connected with the national grid power generation system, once the photovoltaic power generation at any time can not meet the needs of the owners of electricity, the system will automatically remove the electricity from the national grid to use, but the family from the full reliance on electricity The national grid became part of the dependence.
9, if the system surface dust or garbage, the power generation impact?
The impact is very small, because the PV system is related to the irradiance of the sun, not the obvious shadow will not cause significant power generation system impact. Also, the glass of the solar module has a surface self-cleaning function, that is, on rainy days, the rain can rinse the dirty surface of the component. Therefore, the PV system operation and maintenance costs are very limited.
10, photovoltaic system light pollution?
does not exist. In principle, the photovoltaic system is the use of anti-reflective film of the tempered glass, as far as possible to increase light absorption, reduce reflection to increase power generation efficiency, there is no light reflection or light pollution. The traditional curtain wall glass or automotive glass reflectivity of 15% or more, while the first-line components of the photovoltaic glass reflectivity of 6% or less. So lower than the glass reflectance of other industries, there is no light pollution.
11, how to ensure efficient and reliable operation of photovoltaic systems for 25 years?
First, in the product selection on the strict control of quality, we must choose the first-line brand components manufacturers, so as to ensure that the source of components from the source 25 years without any problems:
① component power generation power warranty for 25 years to ensure component efficiency
② have a laboratory (with the production line strict quality control system)
③ large scale (the greater the capacity, the greater the market share, the more obvious economies of scale)
④ goodwill strong (brand effect is stronger, the better after-sales service)
⑤ whether only focus on solar photovoltaic (100% of the PV companies and only the business of photovoltaic companies to do the industry's persistent attitude is different) in the system configuration, we must choose a better compatibility of the reverse device, , Lightning protection module, distribution box, cable and other components to match. Second, in the system structure design and the roof of the fixed, choose a more appropriate fixed way, try not to damage the waterproof layer (that is, not in the waterproof layer on the expansion of the bolts on the fixed way), even if the repair is the existence of future leakage of hidden dangers. The structure must ensure that the system strength enough to deal with hail, lightning, typhoons, snow and other extreme weather, otherwise the roof and property safety are 20 years of hidden dangers.
12, my roof is a cement tile structure, is it able to withstand the weight of photovoltaic systems?
The weight of the photovoltaic system does not exceed 20 kg / square meter, generally as long as the weight of solar water heater can withstand the weight of the roof are no problem.
13, how to install the system after the completion of power supply acceptance?
System design and installation should be a professional installation company to assist you to the local power supply bureau (or 95598) to apply for the appropriate installed capacity, the owner of the basic information and personal distribution of photovoltaic applications to start construction, after completion of the notice to the power supply Bureau, Power companies will send technical personnel on-site acceptance of the project, and free replacement of photovoltaic two-way meter, power generation measurement, in order to follow-up subsidies to pay.
14, how to deal with home photovoltaic power generation, how to deal with lightning, hail, leakage and other issues?
First of all, DC converters, inverters and other equipment lines have lightning protection, overload protection. When the occurrence of lightning, leakage and other abnormal voltage, it will automatically turn off, so there is no security problem. And all the metal borders and brackets on the roof are all grounded to ensure the safety of thunderstorms. Second, the surface of our PV modules are made of ultra-impact resistant tempered glass, through the EU certification have been harsh test (high temperature and humidity), the general climate is difficult to hurt the PV panel.
15, how to do home photovoltaic power generation system?
First of all, we want to collect your basic information, including housing type, roof structure, roof area, monthly electricity and so on. Based on the above information, we will design a more affordable system for you to achieve greater benefits.
16, what services to provide?
Provide one-stop service, including program design, system equipment, transportation installation, and technical support and after-sales service.
17, distributed photovoltaic power generation which equipment?
Main equipment: solar panels, inverters, AC and DC distribution box, photovoltaic meter box, bracket; auxiliary equipment: photovoltaic cables, AC cables, pipe cards, lightning protection and lightning protection grounding. Large power plants also need transformers, power distribution cabinets and other auxiliary equipment.
18, distributed photovoltaic power generation installation area is how much?
According to the actual area of your roof can be used to 1KW, for example, inclined roof area of 8 square meters; flat roof area of 10 square meters. If the increase in capacity, such a push.
