Where does unused solar power go?

Solar power is a renewable energy source that has gained popularity in recent years due to its environmental benefits and cost-effectiveness. However, one question that often arises is what happens to the unused solar power that is generated by solar panels? In this blog, we will explore the answer to this question and shed light on the various ways in which unused solar power can be utilized.

To understand where unused solar power goes, it is important to first understand how solar panels work. Solar panels are made up of photovoltaic cells that convert sunlight into electricity. This electricity is then sent to an inverter, which converts the DC electricity into AC electricity that can be used to power homes and businesses. However, not all of the electricity generated by solar panels is used immediately. In fact, most solar panels generate more electricity than is needed during peak sunlight hours.

So, where does this excess electricity go? There are a few different options for utilizing unused solar power:

  1. Net metering: Net metering is a system that allows homeowners and businesses to sell excess solar power back to the grid. When a solar panel system generates more electricity than is needed, the excess electricity is sent back to the grid and the homeowner or business owner receives a credit on their electricity bill. This credit can then be used to offset the cost of electricity when the solar panels are not generating enough power.
  2. Battery storage: Another option for utilizing unused solar power is to store it in batteries. Battery storage systems allow homeowners and businesses to store excess solar power for use later when the solar panels are not generating enough power. This can be particularly useful during times of high electricity demand or when there is a power outage.
  3. Solar water heaters: Solar water heaters are another way to utilize unused solar power. Solar water heaters use the heat from the sun to heat water, which can then be used for showers, washing dishes, and other household tasks. This can help to reduce the amount of electricity needed to heat water, which can be a significant portion of a household’s energy usage.
  4. Electric vehicles: Electric vehicles are becoming increasingly popular, and they can also be a way to utilize unused solar power. By charging an electric vehicle with excess solar power, homeowners and businesses can reduce their reliance on fossil fuels and further reduce their carbon footprint.
  5. Community solar: Community solar is a system that allows multiple households or businesses to share the benefits of a single solar panel system. In this system, the excess electricity generated by the solar panels is shared among the participants, reducing the need for each individual household or business to have their own solar panel system.


There are several ways to utilize unused solar power, including net metering, battery storage, solar water heaters, electric vehicles, and community solar. By utilizing these options, homeowners and businesses can reduce their reliance on fossil fuels, save money on their electricity bills, and help to protect the environment.
