The Origins of OptimaSolar
OptimaSolar was founded by Wim Seijdel, who has decades of experience in the secondment of technical staff. In 2015, as the demand for technical staff in the solar industry grew, Wim decided to explore the market more deeply, researching products and providers. His conclusion was clear: there was a real need for professionalization within the sector. A challenge he was ready to take on. This led to the creation of OptimaSolar! Today, OptimaSolar focuses on marketing, sales, and after-sales services, with multiple assembly teams working on-site. The energy transition is driving businesses and individuals alike to become more sustainable. Solar energy, when combined with a home battery, Energy Management System (EMS), and potentially a charging station, air conditioning, or heat pump, offers an effective solution with immediate results. At OptimaSolar, we are committed to providing professional and safe advice and installations, ensuring we meet the growing need for sustainable energy solutions.
