Sonne & Wärme
Sonne & Wärme is a regional solar energy provider that quickly grew into a nationwide company with multiple branches across Germany. Their mission is to make photovoltaic solutions accessible, reliable, and tailored to the needs of each customer.
To support this vision, Sonne & Wärme needed a brand identity that not only reflected technical expertise but also conveyed warmth, security, and accessibility.
hetadev partnered with Sonne & Wärme from day one, delivering a full-service branding package including corporate identity, website, and customer-facing video production. Our focus was on building a brand that radiates trust and approachability, while maintaining a professional and modern aesthetic. The website was designed to highlight key selling points such as guaranteed timelines, long-term warranties, and expert installation teams.
By aligning clear communication with strong visual storytelling, we helped establish Sonne & Wärme as a trustworthy solar energy brand—capable of expanding from a regional startup to a nationwide player.
"We are Sonne & Wärme Solartechnik. We commissioned hetadev to create a new website for us as part of our company's rebranding. We booked a complete package with image videos, reference videos, and photo material, and we can truly say that our external presentation has improved by 110 % thanks to hetadev.
Regarding the new website, we have received nothing but positive feedback from our customers. A big thank you to the entire team for the fantastic work! We are extremely grateful and very satisfied with the accessibility, the outstanding quality of the work, and the creation of such an individual and standout concept.
We can wholeheartedly give a more than clear recommendation!"
