Photovoltaic (PV) solar panels

Solar power works by converting light from the sun into electricity. This can be done using photovoltaic (PV) solar panels, which are the most common method for home solar power systems.

Photovoltaic (PV) battery storage

PV battery storage is a crucial component of a complete solar power system. It allows users to store excess energy generated by solar panels during the day and use it during the night, or during periods of low solar irradiance, such as on cloudy days or during certain seasons.

Remember, the right PV battery storage system for you depends on your energy consumption needs, the size of your solar panel system, your budget, and whether or not you're connected to the grid. We can help you make the best decision for your situation.

Here are some key features of PV battery storage systems:

  • icon

    Type of Battery

    There are several types of batteries used in PV systems, including lead-acid, lithium-ion, flow batteries, and more. As of my knowledge cut-off in September 2021, lithium-ion batteries are the most common type used in home solar storage systems due to their high efficiency, long lifespan, and decreasing costs.

    Capacity and power

    The capacity of a solar battery is usually measured in kilowatt-hours (kWh), and it tells you how much electricity the battery can store. The power rating, in kilowatts (kW), indicates the amount of electricity the battery can deliver at one time.

  • icon

    Depth of Discharge (DoD)

    This indicates the percentage of a battery's energy that has been discharged relative to the overall capacity of the battery. Some batteries cannot be fully discharged without damaging the battery, so understanding the DoD is important when comparing battery lifetimes.

    Round-Trip Efficiency

    This is the difference between the amount of energy used to charge the battery and the available energy that can be used afterward. A higher efficiency means you get more economical use from your battery.

    Battery Life & Warranty

    Over time, the battery’s ability to hold a charge will decrease. A battery's warranty will guarantee a certain capacity level for the duration of the warranty.

    Software & Connectivity

    Modern PV battery storage systems often include software for monitoring and controlling how the system operates. This can often be connected to the wider smart-grid, allowing for further cost savings by selling excess power back to the grid if your local regulations and grid infrastructure allow for it.
