The following two conditions must be met, which can be compared for reference:
1. The roof must have sufficient sunlight
This is a very important question that you need to consider. The roof on which you want to install the photovoltaic installation must be oriented as south as possible. Additionally, obstacles such as trees, mountains, and tall buildings can block the amount of light reaching your solar panels. Therefore, you should think carefully before installation, otherwise there will be insufficient sunlight or obstruction, which will affect the power output of the photovoltaic plant.
2. The roof must have enough surface area to install solar panels.
In fact, the power of the photovoltaic energy production system largely depends on the surface area of the solar panels. you install. Because you need to install a certain number of solar panels so that your solar system produces enough energy. The specific quantity can be calculated by professionals according to your actual situation. (This answer is referenced by solar energy expert Guangdong Sunku New Energy)
The solar roof plan mobilizes the development enthusiasm of all parts of society through demonstration projects and promotes the implementation of relevant national policies. Strengthen the publicity of demonstration projects, expand their influence, increase market awareness, and create a good social atmosphere for the development of solar photovoltaic products; promote the implementation of policies such as sharing electricity prices on the grid, form policy synergies and amplify policy effects use photovoltaic applications in buildings as an important part of energy conservationenergy of buildings, actively promote their use in new buildings, energy-efficient renovation of existing buildings and urban lighting.
Advantages: It can save electricity: you can use the electricity produced by the home photovoltaic plant during the day, and you can save one payment item in your living expenses. It can make money: there is a! national subsidy of 0.42 yuan for each kilowatt hour of electricity produced (some places also provide local subsidies), and unused electricity can be sold to the national grid. In the past you spent money to use electricity, but now you earn. money by selling electricity, with a rate of return of over 10%! Sunshade: When photovoltaic modules and cells are laid on a large area of the roof, it can effectively reduce the temindoor temperature of the building 2 - 3 ℃, and also indirectly saves the power consumption of air conditioning. Ability to reduce emissions: A small distributed power generation system with an installed capacity of 3 kilowatts has an annual electricity production of 3,650 kilowatt hours and can generate 91,250 kilowatt hours in 25 years, which is equivalent to saving 36 .5 tons of standard coal, reducing carbon dioxide emissions by 94.9 tons and reducing sulfur dioxide emissions by 0.8 tons. The smog is so bad. Do you really want to pretend to be a good person and give yourself a chance to breathe fresh air?
