Power When You Need It
Solar panels catch sunlight, but batteries make it useful—storing power for dark nights or cloudy days. In Solar Basics on Bharatkiran, we’re explaining how these “power banks” keep rural India running—no grid, no worry!
What’s a Solar Battery?
A solar battery is like a bucket—it holds electricity from panels. Made of chemicals (usually lithium or lead-acid), it stores energy as a charge. Small ones (10000mAh) fit in hubs; big ones (12V 100Ah) power homes.
A charge controller guards it—stops overcharging or draining too fast, keeping it safe.
How Batteries Charge
Panels send DC electricity to the battery—electrons pile up inside, building a charge. In 6-8 hours of sun, a 10000mAh battery fills—enough for 3-4 phone charges or a night of lights. Bigger batteries take longer but store more.

Using Stored Power
When you flip a switch or plug in, the battery releases its charge—DC for phones, AC via inverters for fans. A full battery runs steady; as it empties, power drops—recharge it daily for best results.

Battery Life and Care
Lithium batteries last 3-5 years, lead-acid 5-10—don’t over-drain (below 20%) or overheat them. Clean terminals, store cool—simple care keeps them going. Myth it’s fragile? Read Solar Power Myths Busted.
