Correct Maintenance Will Also Have A Significant Impact On The

  •   How long can the Sealed Solar Battery last?

      There are two ways to answer this question. The first is to determine how long a Sealed Solar Battery can power your house. In many cases, if solar panels do not produce energy, a fully charged battery can keep your house overnight. In order to make more precise calculations, you need to know some variables, including how much energy your home consumes in a day, the capacity and rated power of solar cells, and whether it is connected to electricity, grid.

      To give a simple example, we will determine the battery size required to provide an appropriate solar plus energy storage solution based on the national average data of the US Energy Information Administration. An average American household consumes about 30 kilowatt-hours (kWh) of energy per day, and a typical solar cell can provide about 10 kWh of capacity. Therefore, a very simple answer is that if you buy three solar cells, you can operate at home all day long as long as the batteries support them.

      In fact, the answer is much more complicated. You will also use the solar panel system to generate electricity during the day, which will provide powerful electricity for approximately 6-7 hours of the day during peak sunshine hours. On the other hand, most batteries cannot operate at maximum capacity and will usually peak with a DoD of 90% (as described above). Therefore, your 10 kWh battery may have a usable capacity of 9 kWh.

      Ultimately, if the battery is paired with a solar photovoltaic array, one or two batteries can provide enough power at night when no panels are produced. However, if there is no renewable energy solution, 3 or more batteries may be required to power the entire home for 24 hours. In addition, if you want to install home energy storage equipment to disconnect from the grid, you should install a few days of backup power to solve the possible cloudy days.

      Sealed Solar Battery life

      The general range of Sealed Solar Battery's service life is 5 to 15 years. If the Sealed 12v Battery is installed today, it may need to be replaced at least once to match the 25 to 30-year service life of the photovoltaic system. However, just as the service life of solar panels has increased significantly in the past decade, as the market for energy storage solutions grows, solar cells are expected to follow suit.

      Correct maintenance can also have a significant impact on the life of solar cells. Solar cells are greatly affected by temperature, so protecting the battery from freezing or sultry temperatures will extend the life of the battery. When the photovoltaic cell drops below 30°F, more voltage will be required to reach the maximum charge. When the same battery rises above the 90°F threshold, it will become overheated and the charge needs to be reduced. In order to solve this problem, many leading battery manufacturers (such as Tesla) provide temperature adjustment functions. However, if the battery you purchased does not, you will need to consider other solutions, such as a grounded case. Quality maintenance work will undoubtedly affect the service life of solar cells.
