Store More, Save More, Stress Less
Battery storage isn’t just about saving power—it’s about peace of mind. With the right setup, you can run key appliances during blackouts, avoid high peak rates and get better value from your solar system year-round. Modern batteries are built to last, with smart monitoring, slimline designs and fast response times.
We’ll help you understand how much storage you really need, how it integrates with your current system, and what it can do long term. Whether you’re adding to an existing solar system or starting from scratch, it’s important to get the size and configuration right.
We tailor every install to match your energy use, layout and goals—so you get the most out of your investment without paying for features you don’t need.
How does solar battery storage work?
Battery storage systems collect excess power generated by your solar panels during the day and store it for use later—like at night or during blackouts. Instead of sending unused solar back to the grid, the energy is saved for your own use. This helps reduce reliance on the grid, lower energy bills and provide backup power during outages.
Most modern systems use lithium-ion batteries with smart energy management software that controls when and how the stored energy is used.
Do I need solar panels to use a battery?
Not necessarily. While solar panels and batteries are commonly paired, you can install a battery on its own as a backup energy source. Some homeowners choose to add a battery first and install panels later, or vice versa.
However, combining both from the outset often provides better long-term value and efficiency. If you’re considering standalone battery storage, it's best to speak with an expert to assess how much you'll benefit.
How long do solar batteries last?
Most modern solar batteries last around 10 to 15 years, depending on the brand, usage and how well they’re maintained. Over time, battery capacity will reduce slightly—this is called degradation. Good quality batteries typically retain around 70–80% of their original capacity after a decade.
Some systems include monitoring tools that help track battery health and usage over time, so you can plan for upgrades before performance drops too far.
