At Sunfield Solar, we design and professionally install high-quality solar energy systems for people who want to take control of their power. Whether you’re building a new countryside home, upgrading your existing property, or powering a remote business location, we’ll guide you to the right off-grid or hybrid setup,  tailored to your needs and built to last.

Solid systems built by solid people

Founder Steven Sonneveld brings years of experience as a certified installer of electrical systems (NEN 3140 VP, Netherlands) and has been working together with his team across Portugal since 2023, helping clients in Alentejo and beyond to  become fully energy independent . Our projects range from off-grid family homes and eco-friendly holiday retreats to agricultural facilities and small businesses that want reliable, independent power.

Future proof systems, easy to monitor and maintain

We believe energy freedom should be as reliable as it is sustainable. That’s why we work exclusively with components from brands known for long-term performance. Our preferred partner is Victron Energy, a global leader in off-grid technology, trusted in solar installations worldwide.
