Of course you can, but you need to pay attention to a few things:
1 You need to make sure that the ownership rights of the residence belong entirely to you or that other co-owners sign for YOU. to install the electricity meter before the electricity supply office can install the meter for you. In other words, only villas and farms are more suitable. Small high-rise buildings require signatures from all owners downstairs (office buildings are suitable for commercial systems). ;
2. The photovoltaic meter installed by the power supply bureau is a two-way meter, and the unused electricity can be returned to the power grid and the power supply bureau will give you money according to the local situation. price of coal and electricity. Otherwise, whether you use electricity or send eelectricity in reverse, the ordinary electricity meter will be sent directly and the electricity supply office will charge you double
3. procurement office A solar system with a two-way meter installed enjoys national and local subsidies (provincial and municipal subsidies and district subsidies in Pudong, Shanghai. Only with subsidies can the cost be recovered in 5 to 6 years, otherwise the cost can be recovered). be recovered in 8 years.
4. Charging and storage + self-use is not economically feasible. The battery will be useless after 3 to 4 years. The cost of battery is 2-3 times higher than solar cells.< /p>
5. If there is no local grid electricity to be solved by solar energy, you can consider an off-grid system if you are used to installing solar energy but are unable to obtain approval fromthe power supply. office, you can install an anti-reflux system. The cost of this system is not low, around 5,000 yuan.
It's true. The current national policy provides for subsidies, and the subsidies are valid for 20 years. The total amount of electricity is approximately 0.80 per kilowatt hour, which varies among the three classification regions.
For self-used surplus electricity to be connected to the Internet, the state subsidizes 0.42 yuan per kilowatt hour, plus the electricity price per kilowatt hour in various places.
However, the current problem is that the final sale price of photovoltaic modules is relatively high, resulting in a longer payback period. Therefore, if the price of the modules does not fall, this investment is actually not very expensive. -efficient Of course, if you can get a complete system for around 6 yuan per watt and the return rate is d'around 20%, so it remains an investment.
