Lead-acid solar batteries are one of the most widely used and cost-effective energy storage solutions for solar power systems. They store electricity generated by solar panels for later use, providing reliable backup power when sunlight is unavailable.
These batteries are known for their affordability, proven technology, and ability to deliver high surge currents, making them suitable for both residential and commercial solar applications. However, they generally have a shorter lifespan, lower depth of discharge, and require regular maintenance compared to modern alternatives like lithium-ion batteries.
