Who is eligible for the rebate and how do you apply?

It is a federal program delivered with state participation. Eligibility often includes an existing or new solar system, an accredited installer, and VPP-ready hardware. Check your state’s program site for the latest rules, caps, and required documents. Apply through approved installers who submit compliance paperwork.

What battery size suits a typical home?

Most households target 7–13 kWh to cover evening and early morning use. Larger homes with electric heating, pools, or EVs may consider 10–15 kWh. Start with your annual kWh, peak times, and tariff. Aim to discharge most nights without frequent emptying, leaving headroom for VPP events if you plan to join.

How do virtual power plants affect savings and battery life?

A VPP can add bill credits by discharging during peak events. That may improve payback versus standard feed-in tariffs. Extra cycling can add wear, so choose plans with clear dispatch limits and warranties that cover VPP use. Set a minimum state-of-charge to protect backup needs and everyday self-consumption.

What risks should households weigh before installing?

Check installer capacity, hardware lead times, and grid approvals. Review tariffs, VPP terms, and metering or integration fees. Confirm warranty length, cycle coverage, and service support. Model savings under realistic usage rather than perfect days. Ensure the system is expandable if you plan to add an EV or more solar later.
