Rooftop solar power system

Japan rooftop solar panel power generation system renderings

In Japan, as long as you install solar power equipment at home, you can get a large amount of subsidies from the central government to local governments at all levels. If this equipment has a slight surplus in power supply, you can also sell the surplus power to the power supply company, and the selling price is twice the market price. You can recover the cost of this set of equipment in about 10 years, and you can still enjoy the income from "selling electricity" every year thereafter.

A glimpse of the actual installation in the Japanese community

This house is equipped with a large-capacity "lithium ion battery", which can store the electric energy generated by the solar panel on a sunny day for use in rainy weather. LED energy-saving lighting equipment is used in the house, and a wind speed sensor is provided outside the house to remind the homeowner whether to open the window and turn off the air conditioner according to the outdoor wind speed. Solar power generation equipment can also specifically charge electric vehicles. To a large extent, this kind of house can achieve energy "self-sufficiency".

Changes in the energy structure

Due to the large-scale development and utilization of fossil energy over the years, resulting in a series of difficulties such as resource shortage, environmental pollution, climate change, etc., the importance of energy structure reform is becoming increasingly prominent!

The world's attention has gradually turned to nature's beneficiary "green energy", such as solar energy, wind energy, water energy and other clean and renewable energy. With the goal of "mainly clean energy, supplemented by fossil energy", with the country's vigorous support for development, step by step is being realized. However, because green energy such as wind energy and water energy has relatively high requirements on site conditions and natural conditions, solar energy is more suitable for urban development. Only roof and sunlight can generate electricity, which is definitely the best choice for home power station!

Save money and make money

Is there anything good in this world that kills two birds with one stone? Home distributed photovoltaic is just that!

First, start from the perspective of saving money. Computers, water heaters, air conditioners, cooker hoods, LCD TVs ... this is standard equipment for ordinary household appliances. Naturally, large power consumption is inevitable. After installing the photovoltaic power station, household electricity is taken from solar energy, which greatly reduces the electricity bill.

Secondly, how can we make money? That is thanks to the considerable subsidies that the state strongly supports. At present, household distributed photovoltaics generally adopt a "spontaneous and self-use, surplus electricity online" model. As long as 20 years of subsidies, the state subsidies are 0.42 yuan / degree. Coupled with local subsidy policies around the country, the rate of return is about 15%, and the return is indeed considerable! The monthly or quarterly electricity income and subsidies that ordinary people care about will be paid by the grid company and directly entered 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 the endothermic properties of the solar panel itself ensure that the roof itself is not exposed to sunlight, then the house maintains a relatively cool constant temperature, which achieves a real power saving effect. Therefore, in the summer of 35 degrees high temperature, with distributed photovoltaic insulation, the indoor temperature instantly fell to 30 degrees. Save the air-conditioning charges of large power-consuming households, and the monthly bills can be considerable in a flash.

Change environmental pollution

With the emergence of extreme weather in recent years, haze and sandstorms have raged. Environmental problems are becoming more and more issues that we cannot ignore! Coal power, as the main force of energy for many years, has caused a lot of damage to our environment. And a good industrial economy will certainly form a broad and deep cluster effect. For example, fat papers all over the world are losing weight, so industrial economies such as gyms, vegetable salads, and low-fat milk will be particularly prosperous.

The same is true for the corresponding photovoltaics. It has changed the long-term energy structure of mankind, cut off the dominant position 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 positive energy resources not be sought after and used!

How much impact can that small photovoltaic panel have on the environment? Yatanxin can speak with data! For example, a small distributed power generation system with an installed capacity of 3 kilowatts has an annual power generation of 3,650 degrees, and can generate 91,250 degrees in 25 years. It is conceivable that when solar photovoltaics prop up the roof of our city, the sky corresponding to it will be more blue!

Standard on the roof

In the past, in the design of family buildings, people often pursued the European style with exquisite structure and complex shapes, and always blindly pursued the luxurious retro style when decorating. However, as the minimalist style and the style of glass windows became more and more popular, new home building design standards began to emerge, such as the renovation of the rooftop solar power system.

In foreign countries, the buildings are basically single-family houses. The surroundings are relatively empty and there are no shelters. Therefore, the roof area of the building is used to the maximum extent. After considering the environmental protection and energy saving, people began to gradually reform the roof design. The inclined roof or flat roof has begun to completely replace the European-style multi-roof window roof, which provides the most basic space for the installation of solar power systems.

This trend of fashionable decoration has also blown to China across the ocean. More and more families are choosing solar power system as the standard roof. The distributed photovoltaic roof not only promotes the owner's green environmental protection concept, but also demonstrates the owner's fashion taste.
