First, the energy structure changes
As the large-scale development and utilization of fossil energy over the years, leading to resource shortages, environmental pollution, climate change and a series of dilemmas, the importance of energy structure change is becoming increasingly prominent!
The eyes of the world gradually turned to the grace of nature "green energy", such as solar, wind, water and other clean renewable energy. "Clean energy, fossil energy, supplemented by" as the goal, vigorously support the development of the country, a step by step is being achieved. But the wind energy, water and other green energy because of the site conditions and natural conditions require relatively high, so more suitable for solar energy in urban development. Just roof and sun can generate electricity, this is definitely the best choice for home power station!
What is good in this world do both? Home Distributed PV is!
First, from the perspective of saving money to start. Computers, water heaters, air conditioners, range hoods, LCD TV ... ... This is an ordinary household electrical standard. Naturally, a large amount of electricity is inevitable. Installed photovoltaic power station, the home from the solar power, greatly reducing the electricity bill.
Secondly, how to make money? It will benefit from substantial subsidies to support the country. At present, the family distributed photovoltaic commonly used "spontaneous use, more than electricity online" model. Up to 20 years of subsidies, state subsidies 0.42 yuan / kWh. Coupled with local subsidies around the policy, the yield reached 15%, the income is indeed substantial! People concerned about the monthly or quarterly electricity receipts and subsidies, through the grid company on behalf of payment, directly into the owner of the bank card, very worry-free and reliable!
In addition, the family distributed PV there is an additional invincible skills - cooling insulation. Because the solar panel itself, heat absorption properties, to ensure that the roof itself from the sun exposure, then the house will maintain a cooler thermostat, to achieve a real power saving effect. So in the summer 35 degrees high temperature, with distributed photovoltaic insulation, indoor temperature instantly dropped to 30 degrees. Saving large air-conditioning power consumption, instant monthly bills and considerable.
Third, change the environmental pollution
With the emergence of extreme weather in recent years, haze, Shacheng storm raging. Environmental problems are increasingly becoming a problem we can not be ignored! Coal and electricity as the main force of energy over the years, to our environment has also brought a lot of damage. The good industrial economy will be the formation of extensive and in-depth cluster effect, such as fat paper in the world are losing weight, so the gym, vegetable salad, low-fat milk and other industrial economy will be particularly thriving.
The corresponding PV is also the case, it has changed the human energy structure for a long time, cut off the dominance of coal power to achieve a zero-emission clean standards, so that the entire planet will not be a variety of gases and harmful pollution , So the energy is full of resources can not be sought after and how to use it!
That small photovoltaic panels can have much impact on the environment? Speak with the data! For example, an installed capacity of 3 kilowatts of small distributed power generation system, the annual generating capacity of 3650 degrees, 25 years can generate 91250 degrees, equivalent to saving 36.5 tons of standard coal, carbon dioxide emissions 94.9 tons, 0.8 tons of sulfur dioxide emissions. Can imagine, when the solar PV hold up the roof of our city, with the corresponding sky will be more blue!
Fourth, the standard roof
In the past in the family building design, people tend to pursue the construction of sophisticated, complex European style, in the decoration is always blind pursuit of luxury retro style. But with the minimalist style of wind and windows more and more sought after, the new home building design standard began to produce, such as the roof of the solar power system.
In foreign countries, buildings are basically single-family houses, surrounded by relatively open, there is no shelter, so the roof area of the building to get the maximum range of use, people from environmental protection and energy saving considerations, began to gradually change the roof design, Of the oblique roof or flat roof began to fully replace the European multi-roof roof roof, which for the installation of solar power systems provide the most basic space.
This share of fashion decoration has also blown the wind across the ocean in China, more and more families have opted for solar power systems for the roof of the standard. Distributed PV roof not only to promote the house owner's green concept, but also highlights the owner's fashion taste.
Shanghai Hua Ting Xin Yuan Villa distributed photovoltaic power plant project in June 2016 and the network. Project total installed capacity of 20.754Kwp, a total investment of 180,000 yuan, the annual generating capacity of about 22819 degrees. 25 years total revenue of about 1.02 million yuan power station.
Fifth, the new investment means to lower the cost, lower risk
If the early large-scale investment is to block the spread of the family of the last stumbling block of photovoltaic, PV finance lease is to clear the last hurdle of the pioneers.
Perhaps we have for this new investment means some strange, which for everyone to illustrate!
Pharaoh recently want to own the roof of the plant to install solar power systems to reduce the cost of electricity costs, but since the need to throw out hundreds of thousands of funds at once, Wang wife feel bad, so to find a financing lease license business A, hope A company can pay for their roof to install the system, and then leased to Pharaoh to use, Pharaoh is in accordance with the quarter to the A company to pay the principal plus interest on rent.
So that next door Pharaoh only rent out on the use of solar power systems, and A company's funds are used in the investment, after a lease period, A company can choose to sell the system to Pharaoh, can also be sold other people. This way for Pharaoh is a financing behavior, and A company is indirectly provided development funds for the Pharaoh.
Through this example, we should have the image of PV finance leasing understanding of the bar! PV finance lease not only solve the large amount of investment of the previous owners, more do not require the owners in the entire financing lease to provide any mortgage.
Home solar power system maintenance manual
I. System Description: Grid-connected solar power generation system consists of solar cell array, solar inverter, the United States and Sri Lanka music grid distribution box, photovoltaic racks and meters and other components.
1, solar cell matrix: the total power of solar panels 10KWp, by the 40 250Wp panels; divided into two square, each square of 5000Wp, each panel has a control panel switches and anti- Lightning system, the matrix in parallel together, connected to the inverter input, the inverter issued by the electricity meter measured after delivery to the load.
2, the solar inverter power is 10KW, PV input capacity of 10KWp, the technical parameters refer to the product manual.
3, solar inverters are the core components of solar energy systems, solar modules that it sends out the DC into the load can make some three-phase AC power supply. When the grid power outage or no sun at night, it will automatically stop working, in standby mode.
