Distributed generation Q & a center
Distributed photovoltaic power generation in particular in the vicinity of the user site construction, operation mode to the user side of spontaneous self use, excess power on the Internet, and in the distribution system to balance the characteristics of the photovoltaic power generation facilities.
Distributed photovoltaic power generation to follow the principle of local conditions, clean and efficient, decentralized layout, the principle of the nearest use, and make full use of local solar energy resources, alternative and reduce fossil energy consumption.
Distributed photovoltaic power generation refers to the use of photovoltaic modules, the direct conversion of solar energy into electrical energy of the distributed generation system. It is a new and promising power generation and energy comprehensive utilization. It advocates the nearest power grid, nearby, the nearest nearest conversion, using the principle of not only can effectively improve the power output of photovoltaic power plants of similar size, but also effectively solves the problem of loss of power in the boost and long-distance transport in.
Output power is relatively small.
Pollution is small, the environmental protection benefit is outstanding.
To a certain extent, to ease the tension of the local use of electricity.
Can be used for power generation
Installation capacity can be based on the size of your roof and usually use
electricity to help you estimate how much capacity to meet the needs of your
electricity.
According to the actual area of your roof can be used to calculate the actual area,
in order to 1KW, for example, the roof needs an area of 8 square meters; flat roof
needs an area of 10 square meters. If the increase in capacity, can be such a push.
Income consists of three parts: the use of electricity savings, state subsidies and local subsidies, as well as electricity to sell electricity to the electricity company's electricity income. Taking Shanghai city as an example, the formula is expressed as follows:
Spontaneous use: 0.977 yuan / kWh (such as electricity reached third) +0.42 yuan / kWh (state subsidies, 20 yuan / kWh (+0.4 years) Shanghai municipal subsidies 5 years =1.797 yuan / kWh)
Internet access: 0.477 yuan / degree (benchmark price) +0.42 yuan / degree (state subsidies, 20 years) +0.4 yuan / degree (Shanghai City, 5 years) =1.297 yuan / degree
If the system is 1 kilowatts of 1100 kilowatts of electricity a year to calculate, then a year of income between 1797 to 1426 yuan per kilowatt, of course, the more, the more close to 1976 yuan of the highest income.
Main equipment: solar panels, inverter, AC and DC power distribution box, photovoltaic
measurement meter box, bracket; auxiliary equipment: photovoltaic cable, communication
cable, pipe clamp, lightning arrester grounding and etc.. Large power plants also need
transformers, power distribution cabinets and other auxiliary equipment.
We provide a one-stop service, including program design, system equipment,
transportation, installation, and network technology support and after-sales
service, etc..
First, we need to collect your basic information, including the type of housing, roof
structure, roof area, the monthly electricity consumption, etc.. According to the above
information, we will design a set of the most economical and applicable system plan for
you, in order to realize the benefit maximization.
The impact is very small, because the photovoltaic system is related to solar
irradiance, not obvious shadow will not impact significantly on power system.
Also, a surface self-cleaning glass solar modules, namely in the rainy day,
the rain to the component surface dirt rinse. Therefore, the operation and
maintenance cost of PV system is very limited.
Photovoltaic component life in general in 20 years or so, we win products for
as long as 25 years customer service warranty for 20 years, no menace from the
rear. We will regularly check the special customer service maintenance service
personnel, because our entire system itself has intelligent detection function,
so the maintenance is relatively simple, the general is to remove photovoltaic
glass panels on the guano and leaves the shelter. In addition, PV modules are
modular closure, generally do not need maintenance, direct replacement on the
line, in the warranty period we are responsible for free replacement.
Off grid, also known as stand-alone photovoltaic power generation system, is not dependent on the grid and the independent operation of the system.
The power system due to geographical restrictions, is widely used, as long as the sunlight can be installed and used, so it is suitable for remote areas, without grid Island, fishing, outdoor breeding base, but also can be used as emergency power generating equipment often area.
This system is due to be equipped with battery, and occupied the power system 3050% cost. And the service life of the battery is generally in 3-5 years, and after the replacement, this is the use cost is increased. The economy, it is difficult to get a wide range of promotion and use, so it is not suitable for the use of electricity convenience.
But for the non grid area or frequent power outages in the region, but also has a strong practical. In particular, in order to solve the problem of power failure, the use of DC energy-saving lamps, very practical.
Therefore, off grid power generation system is specifically for non grid areas or frequent power outages in areas where the use of
Grid connected is the need to connect to the public power grid, which is the
solar power, household power grid, the public power grid together, it is nece
ssary to rely on the existing power grid to run the power generation system.
Is mainly composed of solar panels and inverter, solar panels generate electr
icity directly through the inverter converts 220V AC power and to power home
appliances, when the power output of the solar power more than the use of home
appliances, the excess electricity is transported to the public grid; and when
the power output of solar energy can not meet the use of household appliances,
it from the network of automatic. And this whole process is intelligent control,
do not need to open or close. This system can be exempted from the use of batteries,
greatly saving the cost of the system
Factory office building can be installed, as long as you have the idle roof area,
can make full use of it, how much you probably have the roof area, the monthly
electricity about how much, we can help you estimate how much capacity about
installation can meet your usual power required. Or you already have plans to
install more than the capacity of the.
The greenhouse can be installed photovoltaic power generation system, now the country
vigorously support agriculture light complementary, can make full use of resources
can not only meet the greenhouse roof, usually electricity required, and additional
revenue.
We photovoltaic components of the annual decay rate is very small, only 7 per thousand, but the power generation efficiency after 20 years to maintain 87.5%.
