For many people, home PV power storage systems are still a relatively new concept and product. While photovoltaic technology has been around for a long time and has been widely used in large-scale photovoltaic power plants and a variety of smaller devices such as solar water heaters and solar street lights, the popularity of home photovoltaic power storage systems has yet to reach impressive levels.
However, with the advancement of science and technology and the increasing emphasis on renewable energy, home PV power storage systems have gradually developed and matured in residential and commercial applications at home and abroad. In overseas European and American countries, such systems have become national-level equipment and are widely used for both residential and commercial purposes.
Home PV power storage systems utilize solar panels to collect solar energy and convert it into electricity. This electricity can be used for daily household use and the excess can be stored in batteries for emergency use. The emergence of such a system allows home users to use electricity in a more economical and environmentally friendly way, and also provides a certain level of protection in case of power supply interruption or failure.
In addition, the application of home photovoltaic energy storage systems also helps to promote the development and popularization of renewable energy. With the increasing government support for renewable energy and people's awareness of environmental protection, the market prospect of home PV energy storage system is very broad.
The energy saving of home photovoltaic power generation and energy storage system is mainly reflected in the following aspects:
1. Solar energy is a kind of green and clean energy, which does not produce any environmentally harmful substances. Compared with traditional fossil energy, solar energy is a renewable energy source that can be recycled almost all the time. Therefore, using solar energy for power generation can reduce the damage and pollution to the environment.
2. Home PV energy storage system can realize both energy storage and power supply, thus avoiding the pressure of electricity consumption and the trouble of power cuts caused by laddering power supply. In households with high electricity consumption, the use of such systems can greatly reduce the cost of electricity, while realizing self-sufficiency in electricity consumption and reducing dependence on the traditional power grid.
3. From the perspective of input-output ratio, let's take Lenercom's 10KW PV system as an example, it can generate 47 kWh of electricity per day and store 25.6 kWh. This means that this kind of system can realize 24-hour power supply for a family, thus greatly reducing the cost of electricity for the family.
4. The service life of a home solar power system can be up to 25 years or more, and even 40 years if properly maintained. The long service life of such systems allows for stable power generation and supply over a long period of time, thus increasing the return on investment of the system.
5. According to the current electricity price quotes, when synthesized, the cost of using a household PV power generation and storage system is relatively low, which can greatly reduce the household's expenditure on electricity. In addition, if the government's subsidy policy is considered, the rate of return of such a system can reach more than 15%, and the payback period can be within 6-9 years.
Is it safe to install a home PV power storage system?
The safety of home PV energy storage system is completely guaranteed. Nowadays, the home PV energy storage system has gone through many iterations and improvements, whether it is the PV device components at the power generation system end, or the batteries, inverters and energy management system at the energy storage end, all of them can guarantee the safety to the maximum extent.
First of all, the battery is the core component of the home PV power generation and energy storage system, and its durability and safety performance play a crucial role in the safety of the whole system. Most of the batteries used in high-quality home photovoltaic power generation and energy storage systems on the market today are A-grade lithium iron phosphate batteries. The stability of this kind of electric core is very good, can maintain stability at high temperature, not easy to decompose, so it has a high degree of safety. At the same time, its service life is also very long, can reach more than 10 years, so users can rest assured that the use.
Secondly, the current home PV energy storage system also realizes "AMS+BMS+APP" intelligent energy management. This intelligent management system allows users to understand the power generation, energy storage and power supply situation at home online at any time, and adjust and optimize the use strategy in time. In case of failure, the system can automatically repair the faults, thus ensuring the safety and reliability of users' power generation and energy storage.
In addition, the inverter is also an important part of the home PV power generation and storage system. The role of the inverter is to convert DC power to AC power to meet the demand of home electricity. Nowadays, the inverter technology is very mature, which can ensure stable operation under various conditions and also has high efficiency to maximize the role of solar energy.
To summarize, the safety of home PV power storage systems is fully guaranteed. From the hardware equipment such as batteries and inverters to the software technology such as intelligent management system, all of them provide a solid guarantee for the safety and reliability of the system.
Home photovoltaic power generation and energy storage systems have gradually developed and matured, and have become highly popularized equipment in some countries. With the continuous progress of technology and cost reduction, the popularity of this system in China will also gradually increase and become an important development direction of green energy in the future.
