Engineering notes from real NorCal projects.
Sizing guides, technical deep-dives and field notes from Northern California.
Sizing your solar: why the kW number matters less than you think
What actually drives system sizing under NEM 3.0 — and why your twelve-month usage history matters more than the headline kW figure.
Time-of-use rates and batteries: how the arbitrage works
How PG&E time-of-use pricing and a home battery interact, and how to think about charging off-peak and discharging into the 4–9 PM window.
Why TPO is winning commercial flat-roof replacement
How 60-mil TPO single-ply compares to built-up roofing on cost, service life and reflectivity — and what to specify on your next commercial re-roof.
Bidirectional EV charging is coming. Are you ready?
Vehicle-to-home is real in 2026. Wallbox Quasar 2, Ford Lightning, Cybertruck — what works, what is coming, and how to plan.
Service robots in hospitality: how to evaluate the case
How to think about service-robot deployment for hotels, hospitals and restaurants — where they fit, what to budget for, and how to build the business case.
The real cost of going solar in 2026 (NEM 3.0 update)
Cash, loan, and PPA side-by-side. What it actually costs in 2026 and what NEM 3.0 changed.
Day-one benefits of going solar: meter goes backwards.
From day one: start generating your own power, watch your meter go backwards, save money, reduce utility inflation, and start earning a high rate of return on your investment.
