How to Select the Best Batteries for Solar Street and Outdoor Lighting

Calculating Your Capacity Requirements

You need to pick the right battery for your solar lights. First, find out how much power your LED bulbs use. Multiply this by how many hours your lights will be on each night. For example, a 5-watt LED used for 8 hours needs 40 watt-hours each day. Add 20–30% more to cover cloudy days and when the system is not perfect. This extra amount helps your battery store enough energy.

The battery type you choose changes how much energy you need. Lithium-ion batteries hold more energy in less space. They can use more of their stored energy. Lead-acid batteries need to be bigger because they cannot use all their power. If you use a 40-watt light for 14 hours, you need 560 watt-hours. A lithium-ion battery system needs only 623 watt-hours. A lead-acid system needs 2240 watt-hours. This shows why lithium-ion phosphate batteries are the best for most solar lighting.

Tip: Make sure your solar panel is big enough for your battery. If your panel is too small, your battery will not charge fully in winter.
