Three reasons SES Power recommends that your solar power system needs to be equipped with a battery energy storage system

　　Solar power generation has become very popular, because it has the advantages of easy installation, mature industry chain, reasonable price, etc., and with the influence of factors such as global turmoil and local climate intensification, solar power generation in recent years has almost become a popular search on Google word.

　　Although SES Power is a manufacturer with lithium battery products as its main business direction, we often match customers' lithium battery products with solar photovoltaics, inverters, UPS, smart chargers, etc., such as lead-acid replacement products (iron phosphate Lithium battery 12V100Ah, 12V200Ah), UPS high voltage lithium battery system (up to 860V), 3Kw~20Kw off-grid, grid-connected, island-type lithium battery energy storage system, wall-mounted home energy storage system 48V100Ah, 48V200Ah, base station communication backup battery system ( standard 19 inches) and so on.

　　We recommend that your solar power system be equipped with a lithium-ion battery energy storage system for the following three main reasons:

　　Reason 1: Use power from your solar power facility when you need it most (even on cloudy days)

　　Most utilities offer commercial and industrial (C&I) customers time-based tariffs, meaning customers pay more for electricity when the grid is powered at peak capacity. For utilities during the summer peak, it's usually the late afternoon that makes the most money.

　　By deploying a battery energy storage system in conjunction with a solar power generation facility, a portion of the solar power generation facility's electricity can be stored when electricity prices are low, and discharged when electricity prices are high to meet power demand during peak periods. This is called energy transfer, and it's a great way to improve the return on investment of a solar power facility.

　　In the image above, commercial and industrial users with higher electricity bills between 4:00 p.m. and 9:00 p.m. use solar power facilities to charge their battery storage systems from 7:00 a.m. to noon. The battery storage system feeds the stored electricity to the grid later in the day, which can delay the supply of electricity from the solar generation facility until peak electricity demand, thereby reducing the overall cost of electricity, as shown in the blue part of the upper right quadrant of the graph above.

　　Reason 2: Expanding the power generation scale of solar power generation facilities

　　In the case of a utility with a large-scale solar facility and no associated storage systems, there is a limitation: the solar facility can only generate as much power as the transmission lines and grids that are in use can accommodate it.

　　The same is true for commercial and industrial users who have installed solar power generation facilities, only to use as much electricity from solar power generation facilities as possible. There is also a limit, which means that electricity from the grid is still required for a certain period of the day, and those users may prefer to use their own low-cost clean energy.

　　By adopting battery energy storage systems, it is possible to store power generation beyond the capacity limits of the grid, so there is an opportunity to install larger solar power facilities and get more value from their investment.

　　Reason 3: Management outages and grid outages

　　Electricity can travel at almost the speed of light, which means that if it is not stored, it will be used or wasted at the same moment it is generated. Therefore, the production and use of electricity must be balanced. If not, the imbalance between supply and demand can cause voltage dips and spikes in the grid, which can damage many of the electrical equipment used in industrial manufacturers.

　　Solar power generation may have reduced power generation due to weather problems. If the power demand is not reduced, it may affect the load operation.

　　The combination of solar power facilities and energy storage systems can be adjusted for weather-related declines in power generation. The process of managing deviations in solar power generation due to bad weather is called "smoothing solar power generation".

　　A battery energy storage system can also disconnect a user's facility from the grid and keep its equipment running for a predetermined period of time.

　　If users need electricity when the solar power generation is low, they can benefit from the battery storage system of the solar power generation facility. This measure is a form of "energy curing," the process of maintaining the amount of solar power generated for a desired period of time. In other words, it ensures that enough power is always available when the user needs it.

　　It is for these three main reasons that SES Power recommends that your solar power facility be equipped with a battery storage system. Of course, the price of lithium battery energy storage system is not cheap. If you want to get professional advice, you are welcome to contact us.
