🔋 What Are Solar Batteries, and Why Do They Matter?

Solar batteries store unused electricity generated by your solar panels during the day and release it when needed—at night, during outages, or when grid tariffs spike. They’re essential for:

• Backup power during blackouts
• Energy independence from grid fluctuations
• Maximizing self-consumption and reducing bills
• Time-of-use optimization in hybrid systems

⚙️ Types of Solar Batteries

Lithium-ion batteries dominate India’s residential market in 2025 due to falling prices, compact size, and better performance.
