Custom Solar Design & Upgrades

Home Battery & Storage

Correctly sized storage keeps your home running through a blackout and captures surplus solar before the grid can. Integrated, not bolted on.

Sized to your roof and your consumption, not a default kit. CEC-accredited design, precise string layouts, and clean cable runs from panel to inverter.

Level 2 EV Charger Installations

Switchboard Upgrades

Solar, batteries, and EV chargers demand a certified, high-capacity switchboard. We upgrade the backbone before we add the load.

Fast home charging matched to your vehicle spec and your switchboard capacity. Mounted cleanly, wired correctly, certified on completion.

+ Designed as One System

Solar, battery, and charger — built to work together.

Most installers treat solar, storage, and EV charging as separate products. We size and integrate all three from the first design session so they share capacity, not cables.

One accredited team. One design. One install. No subcontractors, no system mismatches, no finger-pointing when something doesn't balance.
