Solar power has become an increasingly popular source of renewable energy in recent years. With the rise of solar panels and battery storage systems, homeowners and businesses alike are able to generate their own electricity and reduce their reliance on the grid. However, one question that often arises is what happens to solar power when batteries are full? In this blog, we will explore the answer to this question and discuss the benefits and limitations of solar power with battery storage.
Firstly, it is important to understand how solar power and battery storage work together. Solar panels generate electricity from the sun’s rays, which is then converted into usable electricity by an inverter. This electricity can be used immediately by the home or business, or it can be stored in a battery for later use. When the batteries are full, any excess solar power is sent back to the grid, where it can be used by other homes and businesses.
So, what happens to solar power when batteries are full? The answer is that it depends on the type of system you have installed. In a grid-tied system, excess solar power is sent back to the grid and credited to the homeowner’s account. This is known as net metering and allows homeowners to offset their electricity bills with the excess solar power they generate. In some cases, homeowners may even receive a check from their utility company for the excess solar power they generate.
In an off-grid system, excess solar power is stored in batteries until they are full. Once the batteries are full, any excess solar power is wasted. This is because off-grid systems are not connected to the grid and cannot send excess solar power back to the utility company. Therefore, it is important to properly size your off-grid system to ensure that you have enough battery storage to meet your energy needs.

While sending excess solar power back to the grid may seem like a waste, it is actually beneficial for the overall health of the grid. By sending excess solar power back to the grid, homeowners and businesses are helping to reduce the demand for fossil fuel-generated electricity. This, in turn, reduces greenhouse gas emissions and helps to combat climate change.
In addition to the environmental benefits, solar power with battery storage also has financial benefits. By generating your own electricity, you can reduce your reliance on the grid and lower your electricity bills. In some cases, homeowners may even be able to eliminate their electricity bills entirely. Additionally, solar power with battery storage can increase the value of your home or business, as it is seen as a desirable feature by potential buyers.
However, there are also limitations to solar power with battery storage. One of the main limitations is the cost. While the cost of solar panels has decreased significantly in recent years, battery storage systems can still be expensive. Additionally, the amount of battery storage needed to meet your energy needs can vary depending on factors such as the size of your home or business, your energy usage habits, and the amount of sunlight your area receives.
Another limitation is the reliability of solar power with battery storage. While solar panels are a reliable source of energy, battery storage systems can be less reliable. Batteries can degrade over time, which can reduce their capacity and lifespan. Additionally, extreme weather events such as hurricanes or snowstorms can damage solar panels and battery storage systems, which can result in a loss of power.
Conclusion
Solar power with battery storage is a great way to generate your own electricity and reduce your reliance on the grid. When batteries are full, excess solar power is sent back to the grid in a grid-tied system, or wasted in an off-grid system. While there are limitations to solar power with battery storage, such as the cost and reliability, the benefits outweigh the drawbacks. By generating your own electricity, you can reduce your carbon footprint, lower your electricity bills, and increase the value of your home or business.
