Five Questions You Need to Clarify before Installing PV Power Plants

Five Questions You Need to Clarify before Installing PV Power Plants

More and more people want to install a photovoltaic power station  on their idle roof, but if you want to install a photovoltaic power station, you need to pay attention to these problems:

1: Did you build your own house? Is it a community of the city? Or villa area?

If your home is self built and the house property right certificate is complete, you can directly bring the original and copy of your ID card, household register and real estate certificate to the power grid company to submit the grid connection application. After the grid issues the grid connection scheme, you can buy the photovoltaic power station for installation. If your home is an urban community, because the roof of the community belongs to the collective ownership of the owners, you need to communicate with all the owners of the building in addition to the property, obtain their signature and consent, and then bring relevant certificates to the power grid company to submit the grid connection application. If your home is a villa area, you need to communicate with the property. The property may not agree to the installation because it does not understand the photovoltaic power station and is worried about damaging the overall beauty of the villa area. However, through reasonable communication and explanation with the property, the general property will agree to install. In many cities such as Shanghai, the roof of villas has been gradually installed. Another thing you need to pay special attention to is that if your villa area belongs to a high self managed villa area, it may be installed with photovoltaic power stations, which can only be used spontaneously and can not be connected to the national grid.

  1. Is it possible to install photovoltaic power plants with idle roofs?

When installing a photovoltaic power station on the roof, the bearing capacity of the house and the surrounding conditions need to be considered. The photovoltaic power station will be used for more than 25 years after construction, so it is necessary to ensure that the roof of the house has a service life of more than 25 years and has corresponding bearing capacity. In addition, the most important problem in the construction of photovoltaic power station is the shielding problem. If there are parapets on the house or solar water heaters installed, or there are trees, poles and other objects nearby, you must avoid the shadow position of these objects, which needs to consider the annual shadow of the objects. Before the installation of photovoltaic power station, scientific measurement and design are required, which can not be installed in an idle position. A small shadow will greatly reduce the power generation of photovoltaic power stations. Don't be greedy.

  1. How much does the photovoltaic power station need to invest? What are the benefits? How soon can I get back?

 According to the current market price of photovoltaic power station, it will cost about 40000 to 50000 yuan to install a 5kW (covering an area of about 50 square meters) photovoltaic power station system. It seems that the investment in the early stage is a little high. However, the state currently gives 0.37 yuan / kWh subsidy to household photovoltaic power generation projects, and there are initial installation subsidies and local kwh subsidies in some regions, which greatly reduces the return cycle of photovoltaic power stations. A 5kW photovoltaic power station can generate about 5400 ~ 9100 degrees of power a year. If all of them are used for their own use, they can save about 4698 ~ 7917 yuan of electricity for a year and recover the cost in 6-10 years according to the 5 gross electricity charge per kilowatt hour of municipal electricity and the state subsidy of 0.37 yuan / kWh.

  1. How many years is the shelf life of photovoltaic power station? How many years can it be used? Is the post maintenance cost high?

The core of photovoltaic power generation system is photovoltaic modules. At present, most enterprises have 10-year product warranty and 25-year linear power warranty (no less than 80% of nominal power in 25 years). In addition, the overall photovoltaic system brand will provide 5-year warranty for the overall system. A set of photovoltaic power station can normally generate electricity for more than 25 years. If qualified products are purchased and high-quality installers are selected for standard construction, it can basically ensure that there is no additional maintenance cost in the later stage. In addition, the current inverters of photovoltaic power stations are equipped with monitoring modules. The daily power generation and whether the power station fails can be checked anytime and anywhere through the monitoring system to analyze the cause of the failure, which greatly facilitates the after-sales operation and maintenance.

  1. Will photovoltaic power plants be damaged in extreme weather?

At present, most brand products are strictly tested before leaving the factory. As long as the products are qualified and the construction standards are met, the photovoltaic power station can withstand general rainfall, snowfall, hail, gale and other bad weather.    

It is recommended that the owner purchase the corresponding power station insurance when installing the photovoltaic power station. In case of similar natural disasters, the insurance company can provide corresponding compensation services. In short, we must conduct investigation in the early stage of the installation of photovoltaic power station, select reliable brands and installers, and ensure the products and after-sales service, so as to ensure that you can obtain long-term and stable income.
