From solar-absorbing granite facades that help regulate indoor temperatures to photovoltaic-embedded limestone pathways that generate electricity, these innovations are transforming passive stone surfaces into active energy contributors.
All-in BESS projects now cost just $125/kWh as of October 2025 2. With a $65/MWh LCOS, shifting half of daily solar generation overnight adds just $33/MWh to the cost of solar.
FEOC rules are reshaping energy storage and the stakes are high. If your BESS supply chain includes restricted foreign entities you risk losing ITC eligibility.
