Residential solar economics have tightened dramatically, with the average LCOE in California reaching $0.07 per kWh in 2023 while system costs, incentives, and storage add-ons continue to move in different directions. Lease demand also slid to 20% in 2023 from 75% in 2015, even as more homes pair solar with batteries and pursue financing. The result is a dataset full of tradeoffs that look simple on a bill but get complicated fast when you price real hardware, soft costs, and utility rules together.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
