❓ Frequently Asked Questions
Q1. Can BESS work with solar panels?
Yes, BESS can be integrated with solar power for maximum savings. This combination allows you to store solar energy during the day and use it during peak hours or power outages, further reducing your electricity costs.
Q2. How accurate is this calculator?
It provides tentative estimates based on standard parameters. Actual costs may vary slightly depending on location, specific equipment chosen, installation requirements, and actual usage patterns.
Q3. How long does a BESS last?
Typically, 10+ years with more than 6000 charge-discharge cycles. Modern lithium-ion batteries used in BESS can maintain 80% of their original capacity even after 6000 cycles.
Q4. What about warranty?
BESS comes with a minimum 5-year replacement warranty at no cost. Many manufacturers also provide performance warranties ensuring the battery maintains a certain capacity percentage over the warranty period.
