Brand Guidelines v1.0 — April 2026
01 — Introduction

Brand Story

Hanergy makes solar energy management accessible and intelligent. Our platform integrates with Home Assistant to distribute surplus solar and wind energy across home devices, transforming how people consume renewable energy.

The Name

Home Assistant + Energy = Hanergy. A clear, functional name that communicates exactly what we do. No abstraction, no ambiguity. Smart energy management for the Home Assistant ecosystem.

Our Mission

To make solar energy management accessible and intelligent for every home. We believe surplus energy should never go to waste. Hanergy ensures every watt of solar or wind power is intelligently distributed where it matters most.

The Pixel-Art Aesthetic

Our pixel-art identity represents the digital, grid-based nature of energy management. Each pixel square mirrors the modularity of solar panels, the granularity of energy data, and the precision of load balancing. The 11×11 grid is our foundation — structured, systematic, and unmistakably digital.

03 — Color

Color Palette

Our palette centers on Solar Gold — a warm, energetic amber that represents solar power. It is supported by sustainable greens and a sophisticated neutral system built on deep navy.

Accessibility Notes

Contrast Ratios: Solar Gold (#F6B215) on Deep Navy (#0F172A) passes WCAG AA at all sizes. Gold on white requires 18px+ bold or 24px+ regular for AA compliance. Always use Burnt Amber (#936A0D) for gold-toned text on light backgrounds.
04 — Typography

Typography

Two typefaces work together to balance technical precision with readability. Space Grotesk for headings and UI elements, Inter for body text and documentation.

Primary — Space Grotesk

Used for headlines, UI labels, buttons, and navigation. A geometric sans-serif with a technical, modern feel that pairs with our pixel aesthetic.

05 — Grid System

Pixel Grid System

The 11×11 pixel grid is a core brand motif derived from the logo. Use it for backgrounds, patterns, illustrations, and spacing decisions.

11×11 Brand Grid

The sunburst icon fits within an 11×11 pixel grid. This grid can be abstracted into decorative patterns, data visualizations, and layout foundations.

Spacing Scale

Base unit: 4px. All spacing derives from multiples of the base unit. Use this scale for margins, padding, gaps, and component sizing.

Pattern Applications

The pixel grid can be used as a subtle background pattern, section divider, or decorative element. Keep it understated — use Pale Gold or 5-8% opacity of Solar Gold on backgrounds.

06 — Icons

Iconography

Product icons use the Lucide icon set for consistency with the Home Assistant ecosystem. Brand illustrations follow the pixel-art style established by the logo.

Product Icons — Lucide

Use Lucide icons at 24px default size, 1.5px stroke weight. Match icon color to the text context. Use Solar Gold for interactive/highlighted states.

Lucide icons: lucide.dev — MIT License. Already integrated in the Hanergy product.

Pixel-Art Brand Icons

For brand materials, marketing, and illustrations, create pixel-art style icons matching the logo aesthetic. Use whole-pixel alignment on a grid.

09 — Voice & Tone

Brand Voice

Hanergy communicates with technical clarity and accessible language. We are smart and direct — never corporate, never condescending.

Voice Principles

Technical but Accessible
Explain complex energy concepts in plain language. Use precise technical terms when they add clarity, but always define them on first use.
Smart and Direct
Get to the point. Respect the reader's time and intelligence. Lead with the most important information.
Sustainability Without Greenwashing
Talk about real energy savings with real numbers. No vague claims about "saving the planet." Focus on measurable household impact.
Community-Oriented
We are part of the Home Assistant ecosystem. Acknowledge the community. Use collaborative language ("we," "together") over corporate speak.
