Your Partner for a Green Future

With extensive experience in planning and implementing photovoltaic systems, we are committed to advancing the energy transition in Berlin, Brandenburg and beyond. We believe climate protection starts with individuals, so we make it easy for you to embrace renewable energy.

Customized PV Tailored to Your Needs

Every project is unique. That’s why we design your PV system based on individual requirements, ensuring every aspect of your property is taken into account. Unlike standardized online processes, our consultations and sales are conducted personally on-site. Even after installation, we offer ongoing support to keep you in good hands.

Complete Transparency From Start to Finish

Navigating the photovoltaic industry can be overwhelming, but not with sunday solar. We provide transparent pricing with no hidden costs, no advance payments and no unexpected charges. Our offers are independent of manufacturers, allowing us to fully meet your preferences. Most projects are completed within six weeks.

People and the Environment at the Core

We prioritize satisfaction — for both our customers and team. With flexible work models, fair pay and a 4-day work week, we foster a sustainable and motivating workplace. Our guiding principle is: “Live and let live.”

Our in-house teams ensure quality and efficiency without relying on subcontractors. Regional installation teams work locally, adhering to the latest standards for professional execution.

“Our journey began modestly: three colleagues who shared not only professional expertise but also a shared vision and values.

We wanted to create something meaningful and contribute to the energy transition through solar power. Recognizing challenges in the existing energy sector, we aimed to provide people with sustainable, independent energy alternatives.

Combining technical expertise, business acumen, and project management, we turned an idea into a thriving company. Our first success came sooner than expected, confirming our path.

Today, sunday solar embodies our vision and courage to innovate.”
