Free Solar Battery Sizing Calculator | PUMA SUNERGY
As you can see, properly "sizing your battery" is the most critical step to making your investment as cost-effective as possible. Before we jump to the calculator, let''s get to know the
Selecting the optimal battery size for your solar energy system involves various factors that directly impact your energy storage needs. Understanding your energy consumption is crucial. Start by calculating your daily energy usage in kilowatt-hours (kWh). Break down your needs by listing devices, their wattage, and usage duration.
Here's what you should know about solar battery sizes. Battery capacity measures how much energy a battery can store, typically expressed in kilowatt-hours (kWh). For instance, a 10 kWh battery can provide 10 kWh of electricity under optimal conditions. To determine the capacity you need, calculate your daily energy consumption.
Suppose you consume 30 kWh daily. If you choose a lithium-ion battery with a usable capacity of 10 kWh and a DoD of 90%, you'll need at least three batteries to meet your daily needs. By understanding these components, you'll be equipped to choose the right size battery for your solar energy system, ensuring seamless and efficient operation.
Translate nightly kWh into a solar battery size with usable capacity (DoD × round-trip efficiency). Typical ranges: 10–20 kWh for essentials; 40–90 kWh for whole-home in tough climates. 1.
