Our Story

Over Easy Solar embarked on an impactful journey as a solar startup. Throughout the year, we achieved significant milestones, receiving crucial grants, submitting two patent applications, and proudly showcasing our prototype at prestigious institutes. Our unwavering dedication to innovation and sustainability solidified our position as pioneers in the renewable energy industry.


Over Easy Solar proudly showcased its solar innovations with ten real-world pilot installations at locations in Norway and three other European countries. Recognized as Solar Startup of the Year by SolarPower Europe in March 2022, our presence at Intersolar Munich in June also marked a bright beginning. Over the year, we expanded our team to seven members and connected with important partners both for manufacturing, sales and distribution.


Over Easy Solar started the manufacturing of the product and went through necessary certifications and tests, importantly, the wind tunnel certification that confirmed our system to be ballastfree under most relevant conditions. Several new pilots came up in the first half year, and our first full-scale installation of 45 kWp on a green roof in Oslo came up in June. Later in the year, we delivered to a 102 kWp installation in Oslo and several smaller projects in Norway and other EU countries.
