A solar system without batteries only works when the sun is shining. Battery storage allows you to capture excess solar energy during the day and use it at night, during outages, or peak tariff periods.\n\nThere are two main battery chemistries used in residential solar: lithium-ion (LiFePO4) and lead-acid (typically tubular). Lithium batteries are lighter, last 4-5 times longer, charge faster, and although more expensive upfront, offer the best value over their lifetime.\n\nChoosing the right battery capacity depends on your nightly energy usage and how independent you want to be from the grid. Our engineers perform a detailed energy audit to size your battery bank correctly.\n\nWith the right storage, you can enjoy uninterrupted power and complete peace of mind.
