From the moment you add a solar battery to your solar system, eventually, you notice the changes in the performances of the system output between different seasons.
As the solar panels work harder and longer during the summer months as compared to winters. Your battery also works more efficiently in summers than in winters. It all depends and comes down as the amount of sun hitting the solar panels decreases.
During summers, since your panels will receive more sunlight so the panels will generate more electricity. This means that you will get the best performance as well as most output from your solar battery.
During winters, the solar panels will receive less sunlight which means it produces less electricity during days. So there will be less excess electrical power available for charging the battery.
As a result, batteries will be discharged and homes will be switching to grid energy for more electricity. Then the sunrise again the next morning and panels generate electricity again.
What does this mean for me?
If you are living in Perth, you will experience the difference in output between summer and winter. You don’t have to worry about it as these are pretty normal during the seasons.
The point to be remembered is that if you are adding a solar battery to your system, you are maximizing your use of solar power.
If you are adding a solar battery or not to your system, the panel’s performance will be the same. But, the difference is that how much solar energy is stored in the battery for further use.
