Frequently Asked Questions: All You Need to Know About Solar & Battery Solutions with Sun-I Solar.

1. What are the benefits of adding a battery to my solar system?

Adding a battery provides backup power during grid outages, allows you to store excess solar energy for later use, and can lower your reliance on the grid, which can save on energy bills. It also makes your home more energy-independent.

2. How do I know what battery size I need for my home?

The ideal battery size depends on your energy consumption, the critical loads you want to support, and how long you want the backup to last. Our calculator can help you determine the best battery size based on these factors.

3. Can I add a battery to my existing solar system?

Yes, many batteries can be integrated into existing solar setups. Depending on your current system, a compatible battery and inverter may be required. Our team can provide a tailored solution based on your setup.

4. How long does a battery system last?

Most residential batteries last 10-15 years, depending on use and maintenance. Quality batteries often come with warranties covering up to 10 years. Our team can guide you on the best options with optimal durability.

5. What happens to my solar system if the grid goes down?

Without a battery, most grid-tied solar systems shut down during a power outage to protect utility workers. With a battery backup, however, you can keep essential loads running even when the grid is down.

6. Will a battery increase my home's value?

Yes, installing a solar battery can add value to your home by making it more resilient to outages and reducing utility costs. Potential buyers are often attracted to energy independence and the long-term savings associated with solar batteries.
