Unlocking Energy Independence With Battery Storage

As the demand for sustainable energy solutions continues to rise, homeowners with existing solar energy systems are increasingly turning to battery storage to enhance their energy independence. In this blog post, we explore why adding battery storage is a game-changer for those looking to maximize the potential of their solar investment.

How Does Battery Storage Work?

The energy generated by the solar panels is channeled to the inverter, where the direct current (DC) undergoes conversion into alternating current (AC). Initially, this produced energy is consumed within the home. Any surplus energy not used within the home is then sent to charge the battery If the solar system continues to generate an excess of energy and the battery reaches its full capacity, the extra energy is then fed back into the grid. In certain jurisdictions, this surplus energy exported to the grid may result in credits per kilowatt-hour, a practice commonly referred to as net metering.

During nighttime hours or periods when your solar system isn't generating power, in certain jurisdictions, youor can choose to either draw upon the energy stored in the battery or opt to useutilize electricity sourced directly from the grid. However, dDrawing from the grid ensures that the battery remains fully charged in case of an emergency. If you have net metering, this approach also allows you to use any accumulated credits that are available to you. Additionally, this approach enables you to make use of the credits accumulated through net metering.

During a power outage, all grid-tied solar systems are automatically deactivated to ensure the safety of utility workers conducting maintenance on power lines. Nevertheless, if sunlight persists during the outage, the solar panels will continue to supply energy to the battery backup. In instances where the panels cease to generate power, the house will exclusively draw energy from the battery. It's important to note that the battery has a limited capacity and can power select appliances, up to 30 amps, including items like the refrigerator/freezer, lighting, Wi-Fi, sump pump, and more.

Benefits of Battery Storage

There are two main benefits of adding solar battery storage to your system. They are:

  • Unleashing energy independence and resilience. Adding battery storage transforms your solar system into a 24/7 power source. By capturing excess solar energy production during the day, you break free from the constraints of daylight hours, ensuring a continuous and reliable power supply to critical appliances and systems in your home. This newfound energy independence is particularly valuable during grid outages or emergencies, when homeowners with battery storage have increased resilience.
  • Boosting financial viability and incentives. During times when their system isn’t generating power, homeowners with solar battery storage can maximize their investment by choosing to draw from their battery or directly from the grid, depending on when it’s financially beneficial to do so (to avoid costlier time-of-use pricing, for example). While the initial investment in battery storage may seem significant, numerous financial incentives and rebates are available. Explore government incentives and tax credits to make the economic transition to solar-plus-storage more feasible and cost-effective.

Choosing the Right Battery Technology:

Selecting the appropriate battery technology is crucial for optimizing your solar-plus-storage system. Lithium-ion batteries are a popular choice due to their high energy density, long cycle life, and relatively low maintenance. However, it's essential to consult with a professional to determine the best fit for your specific needs.
