Voltaic.

A brand identity for a home-battery company.

I built the whole identity on one mark: a yellow core held inside slate-gray brackets, drawn to show power moving from one home to the next.

I put the mark on the hardware: battery, inverter, and EV chargers in one slate-bracketed family, each badged Voltaic and edged in the same yellow.

02Overview · The brief

The brief, and the idea I answered it with

The brief asked for a brand around three ideas: sustainability, empowerment, and innovation, for homeowners aged 35–55 and a younger 22–34 group. I answered with a single mark. The yellow core is built from a leaf, a lightning bolt, and a turbine; the slate-gray brackets around it stand for the grid, and the rounded corners read as power given and taken back.

The matrix is the full inventory: 19 artifacts, from the first logo drawing to the ads and stationery.

The Voltaic lockup applied across cream, yellow, violet, teal, and dark swatch tiles, plus a photo of the white mark on a wall-mounted EV charger on a wood-slat wall — the one mark holding across every ground.
The same mark on white, Harmony yellow, and black.

I built one mark and applied it unchanged, from the logo to the printed utility bill.

03Process · The system

Building the mark

Three movements: the mark drawn on a measured grid, the type chosen to read from a phone to a billboard, and the mark set on a dark ground.

Movement 01 · The construction

The mark, on a measured grid

The Voltaic logomark construction on a dark ground: the two offset rounded forms and corner brackets laid over a grid with yellow pixel callouts (300, 500, 260, 160, 100, 60, 50 px), labelled Logo Mark and Energy Grid Exchange.

The Voltaic logomark in three colour treatments: charcoal-and-yellow on white, solid black on yellow, and yellow-with-white-brackets on dark. The mark is two offset rounded squares inside corner brackets.

I ran the system through four colorways, cream, Harmony yellow, Space violet, and Cerulian teal, then onto a wall charger at product scale.

Movement 02 · The type

Choosing the type

I set the headlines in Deuterium and the body in Allumi. The audience is a whole community, so I needed type that holds up at small sizes on a phone screen and at large sizes on a street-side board.

The brand in use

Three ad scenes, a four-storey billboard, and a utility bill. The figures on it, 75 kWh, $27, and 4.5★, are the concept’s own, not real results.

Three ad scenes
A Voltaic ad: a row of wall-mounted inverter and battery units in a modern garage, one unit framed in yellow with greenery, beside a white panel carrying the VOLTAIC lockup.

A Voltaic ad: a hard-hatted installer mounting a solar panel in front of a timber chalet home, the panel framed in yellow, beside a white panel with the VOLTAIC lockup.

A Voltaic ad: an aerial of a suburban neighborhood with one teal-roofed house framed in yellow, beside a white panel with the VOLTAIC lockup; the community sharing one grid.

A branded Voltaic construction-site billboard under a crane: a large ‘Power your way’ board with the VOLTAIC lockup, a secondary ‘Clean Energy / Solar / Community / Wind’ panel, and a wall-charger photo at the right.

The utility bill

I designed the homeowner’s statement to carry the numbers: 75 kWh given back to the grid, a $27 average monthly bill, and a 4.5-star grid-contribution score.

The bill is the last piece I designed. These figures are the concept’s own, not real results.

What it taught me

Voltaic taught me restraint: I drew one idea once, then held it steady across four colorways, a slide deck, the ads, a billboard, and the utility bill.
