Lunar Energy

ID

Lunar Energy, a home battery start-up, partnered with Daylight Design to create their company branding, industrial design and app design. I worked closely with Lunar's engineering team, evolving the product from concept to production and overseeing significant internal and external design changes as the product went into production.

A story of day and night

The lunar battery stores energy generated from solar panels during the day and powers the home at night. This cyclical usage pattern drew graphic parallels with lunar/tide charting.

The logo

The duality of "day and night" inspired the double semicircle logo, representing both the sun and moon as well as the cyclical power usage cycle.

Battery Design

The logo is applied vertically on the battery unit. This protruding "lunar wave" creates a dynamic shadow across the battery's surface that shifts throughout the day.

App Design

Similarly the app displays fluctuating energy units with a background scene synced to the lighting outside.

The lunar battery stores energy generated by solar panels during the day and powers a home at night. This core concept of the brand is anchored on the two semi-circled logo (inspired by the sun and moon) which represents the batteries charging and discharging cycles. This brand concept was applied in the industrial design in the form of the "lunar wave" which flows up the front face of the battery.

Concepts

Early concepts explored how a battery unit could aesthetically integrated into a home. Modular and expandability were a key design feature that would allow users to configure their battery unit to fit their individual home’s power needs.

Selected Design

Our design was inspired by the dynamic shadow produced on sand dunes as the sun moves through the sky. The battery modules allow for one person to install the battery, lowering the installation cost. The Lunar Arc flows up the battery creating visual cohesion out of the modular stack.

Manufacturing

A reversible cover design allowed a single tool part to create a dynamic battery cover while also minimizing production costs. I oversaw a significant design change, switching materials from aluminum to plastic, due to supply chain constraints.

Details

Working closely with Lunar engineers, I detailed ventilation, emergency power switches, communication lights, antenna placement, conduit entrances.

Prototypes

We worked with domestic and international vendors to prototype the battery, and evaluate proportions, paint textures and interactions.

Color Material Finish

Battery units offered in Midnight Blue and Moon Grey reflect the Lunar brands light and dark duality. A light texture and matte finish on both the logo and powder coat bring out the Lunar Arc’s two toned lighting effect.
