Solar Icons

Solar is a sprawling, 7,404-icon collection released by 480 Design, distributed under CC BY 4.0. What makes Solar distinctive is that every concept ships in five coordinated visual styles in the same release: linear, broken, bold, bold-duotone, and outline. That means you can mix expressive duotone icons in marketing pages and use the same library's linear set inside a dashboard without losing visual cohesion. The icons cover a wide topical range — interface, e-commerce, finance, weather, transportation, and more — and are sized on a 24×24 grid with carefully tuned strokes. Because the license is CC BY rather than MIT, you do need to attribute the authors when redistributing the assets, but commercial use is permitted. Solar is a good choice when you want range, range of style, and a coherent visual language across the entire site.
