While batteries are not strictly necessary for most grid-tied solar systems, they can offer significant benefits.
Here’s a breakdown:
Grid-Tied Systems Without Batteries
Net Metering:
This is the most common setup. Excess solar energy is fed back into the grid for credits, offsetting future energy costs
No Backup Power: During power outages, your system will shut down to prevent backfeeding electricity into the grid, ensuring safety for utility workers.
Grid-Tied Systems with Batteries
Energy Independence: Batteries store excess solar energy for use during cloudy days or power outages.
Backup Power: With batteries, you can continue to use essential appliances even when the grid is down.
Peak Demand Reduction: Batteries can help you reduce your reliance on the grid during peak usage times, potentially lowering your electricity bills.
So, whether or not you need batteries depends on your specific needs and priorities. If energy independence and backup power are important to you, a battery storage system might be a worthwhile investment.
