Five reasons to install a home rooftop solar power system
With the gradual popularity of solar photovoltaic, people gradually understand and recognize this new thing. Pieces of blue roofs are propped up, slowly spreading to all corners of the world's territory. What is the magic of distributed photovoltaic roofs that can take the world by storm? OFweek tells you, five reasons to install solar power systems on the roof of your home !
1. The transformation of energy structure
Due to the large-scale development and utilization of fossil energy over the years, a series of difficulties such as resource shortage, environmental pollution, and climate change have been caused. The importance of energy structure reform has become increasingly prominent!
The eyes of the world have gradually turned to the “green energy” blessed by nature, such as solar, wind, and hydropower and other clean and renewable energy sources. With the goal of "clean energy as the mainstay and fossil energy as the supplement", with the country's strong support and development, it is being realized step by step. However, green energy such as wind and hydropower has relatively high requirements for site conditions and natural conditions, so solar energy is more suitable for urban development. Only the roof and sunlight can generate electricity. This is definitely the best choice for home power stations!
2. Save money and make more money
Is there any good thing in this world that can kill two birds with one stone? Home distributed photovoltaic is!
First of all, start from the perspective of saving money. Computers, water heaters, air conditioners, range hoods, LCD TVs... These are standard appliances for ordinary households. Naturally, large electricity consumption is inevitable. After the installation of photovoltaic power stations, household electricity is derived from solar energy, which greatly reduces electricity bills.
Secondly, how can you make money? That would benefit from the considerable subsidies strongly supported by the state. At present, household distributed photovoltaic generally adopts the mode of "self-generated and self-use, surplus electricity goes online". For a 20-year subsidy period, the state subsidy is 0.42 yuan/kWh. Coupled with the local subsidy policies in various places, the rate of return has reached about 15%, and the benefits are indeed considerable! The monthly or quarterly electricity fee income and subsidies that ordinary people care about will be paid by the power grid company directly into the owner's bank card, which is very worry-free and reliable!
In addition, home distributed photovoltaic has an additional invincible skill-cooling and heat insulation. Because of the heat-absorbing properties of the solar panel itself, the roof itself is not exposed to the sun, so the house also maintains a cooler constant temperature, achieving a real power saving effect. Therefore, in the summer of 35 degrees high temperature, with distributed photovoltaic insulation, the indoor temperature instantly drops to 30 degrees. It saves the air-conditioning fee of the large electricity-consuming households, and the monthly bill is quite a lot in an instant.
3. Change environmental pollution
With the emergence of extreme weather in recent years, haze and sandstorms have raged. Environmental issues are becoming more and more issues that we cannot ignore! As the main force of energy for many years, coal power has also brought a lot of damage to our environment. And a good industrial economy will surely form a broad and in-depth cluster effect. For example, fat papers all over the world are losing weight, so industrial economies such as gymnasiums, vegetable salads, and low-fat milk will be particularly prosperous.
The corresponding photovoltaic is the same. It has changed the long-term energy structure of mankind, cut off the dominance of coal power, and achieved a completely zero-emission clean standard, so that the entire planet will not be polluted by various gases and harmful substances. How can such a resource full of positive energy not be sought after and used!
How much impact can a small photovoltaic panel have on the environment? Speak with data! For example, a small distributed power generation system with an installed capacity of 3 kilowatts has an annual power generation of 3650 kWh, which can generate 91250 kWh in 25 years, which is equivalent to saving 36.5 tons of standard coal, reducing 94.9 tons of carbon dioxide and 0.8 tons of sulfur dioxide. It is conceivable that when solar photovoltaic supports the roof of our city, the sky corresponding to it will be more blue!
Fourth, the standard configuration of the roof
In the design of family buildings in the past, people often pursued the European style with exquisite structure and complex shape, and always blindly pursued the luxurious retro style when decorating. However, as the style of minimalism and glass windows became more and more sought after, new home architectural design standards began to emerge, such as innovative roof solar power generation systems.
In foreign countries, buildings are basically single-family houses with relatively open surroundings and no shelters. Therefore, the roof area of the building is used to the largest extent. After considering both environmental protection and energy saving, people began to gradually reform the roof design, covering a large area. The sloping roof or flat roof began to completely replace the previous European-style multi-roof roof, which provides the most basic space for the installation of solar power systems.
This trend of stylish decoration has also blown to China on the other side of the ocean, and more and more families choose solar power generation systems as the standard on their roofs. The distributed photovoltaic roof not only promotes the owner's green environmental protection concept, but also demonstrates the owner's fashion taste.
The distributed photovoltaic power station project of Shanghai Huating Xinyuan Villa was connected to the grid in June 2016. The total installed capacity of the project is 20.754Kwp, the total investment is about 180,000 yuan, and the annual power generation is about 22,819 kWh. The total revenue of the power station in 25 years is about 1.02 million yuan.
5. New investment methods make the cost lower and the risk lower.
If the large-scale investment in the early stage is the last stumbling block to the popularization of distributed photovoltaic households, then photovoltaic financial leasing is the pioneer to clear the last obstacle.
Maybe you are still a little unfamiliar with this new investment method, here is an example for you!
The Lao Wang next door recently wanted to install a solar power system on the roof of his factory to reduce the cost of electricity bills, but self-investment required hundreds of thousands of funds at once. Lao Wang's wife felt distressed, so she found a company with a financial lease license. A, I hope that company A can pay to install this system on its roof, and then lease it to Pharaoh. Pharaoh will pay company A a rent of principal plus interest on a quarterly basis.
In this way, Lao Wang next door used the solar power system only for rent, and Company A’s funds were also used for investment. After the lease period, Company A can choose to sell the system to Lao Wang or to other people. This method is a financing behavior for Lao Wang, and Company A indirectly provides Lao Wang with development funds.
