I'll be straight with you: I don't publish battery pricing anymore, because every home is genuinely different — backup needs, panel compatibility, electrical configuration, and which rebates you qualify for swing the number by thousands. Ballpark for battery-only projects after incentives: $15,000-$18,000 per battery, but the SDCP rebate, CEA's $0-down program, and VPP payments can transform that math completely.
What I'll say with confidence: battery pricing is only going up. Materials are constrained, demand is exploding, and every VPP program launched makes storage more valuable. Adding a battery retroactively also always costs more than including it with solar. If a battery is in your future, the cheapest day to do it is today.
