U.S. grid electricity prices have risen 31% in five years, while solar+battery systems cost $20K–$50K+ to deploy and still underperform — with only 30–60% of solar directly consumed and batteries oversized by 30–100%. Solar, batteries, EVs, and smart devices operate in silos, adding 20–40 hours of engineering per installation and leaving homeowners without a unified intelligence layer to coordinate all energy assets.
