À propos de cet audio
Solar & heat pumps can be a dream team or a challenge when time‑of‑use rates and sloppy sizing collide. Brent Davidson joins Ben Walker and Sam Myers to share a contractor‑first playbook: fix the enclosure, model the real load, then pair PV, storage, and controls so bills go down and stay down. We discuss home battery technology, how TOU windows change design decisions, and why rules of thumb (500‑sq‑ft‑per‑ton) still wreck outcomes. Brent also previews the US Heat Pump Summit happening in November 2025. This event is built to connect technical training with business systems so good work actually scales.
