Things to Consider before Installing a Rural Solar Power Station


A solar power generation system is not a standardized product. The same configuration may not be suitable for all users. A solar power generation system needs to be designed and configured according to the user's situation. Many customers know little about it. So, for users who intend to purchase solar power generation systems, what considerations should they make before purchasing?
 
Considering the objective environment of the place of residence
Usually, individuals applying for grid connection of solar photovoltaic power stations do not need many qualifications except for clarifying the right to use the roof. However, apart from policy regulations, some objective factors need to be considered before installing solar photovoltaic power stations. It is recommended to consider the installation location and area of photovoltaic modules. Generally speaking, south roofs or east-west facing roofs are more suitable for installation. In addition, families with yards or balconies can also consider installing sun sheds, car sheds or sunshades.
 
A kilowatt photovoltaic power generation system can generate about four kilowatt-hours of electricity per day on average per year. Flat laying requires a roof area of 10 square meters, while inclined laying requires about 7 square meters depending on the angle. Users can roughly estimate how big the photovoltaic power generation system they need based on electricity consumption and available area. At present, villas, townhouses, remote areas and a house not sharing an entrance with others in rural areas are more suitable for solar photovoltaic power station projects. If it is a residential area, the procedures may be cumbersome, requiring the signature of 2/3 of the owners of the entire unit before installation.
 
Considering personal economic factors
Although the personal distributed photovoltaic power generation project has a large investment, it is a long-term and environmentally friendly investment. According to calculations, taking the current sunshine situation in Shanghai as an example, every 10,000 RMB of equipment can generate 1,200 kilowatt-hours of electricity a year. Assuming that 100% of the equipment is integrated into the national grid and all subsidies are given, each kilowatt-hour of electricity can conservatively get about 1.3RMB. The subsidy of the current electricity price in Shanghai far exceeds this. The annual income is 1560 RMB, and the cost can be recovered in 6.41 years. The service life of photovoltaic equipment is generally about 25 years, and the money you make in the next 18 years is net profits.
 
How to choose the grid connection mode?
The State Grid adopts an encouraging and cooperative attitude towards the application of distributed photovoltaic power generation, and allows owners of photovoltaic power stations to adopt a payment model in which surplus power generated for self-use or all electricity consumed is connected to the grid. Which of the two grid-connected modes is more profitable? According to the calculations of industry insiders, if the electricity consumption is not too great and the electricity price does not exceed the first grade, the full-pay online mode is more appropriate in terms of current income. If the power consumption is particularly great and reaches the third-grade electricity price standard, it is recommended to use the self-generated and self-used surplus power grid mode, which is more appropriate. From the perspective of the national strategy, it is natural to encourage home users to adopt the mode of surplus electricity for self-use, which is also in line with the characteristics of the distribution.
 
Choosing installers
A photovoltaic power generation system mainly includes photovoltaic modules, inverters, various wires, meters and monitoring devices. Once the quality of the equipment is not good, it will not only affect the safety of its electricity, but also affect other users. It is recommended that you choose regular and high-quality photovoltaic modules and related equipment when purchasing to avoid worries.
 
The above are some factors that need to be considered before installing a solar photovoltaic power station. I hope it can be helpful to you who have needs in this area.
