Christian Gyr erstellte, zusammen mit seiner «SolarEcos GmbH», im Herbst 2023 in unserm Einfamilienhaus in Bettingen eine Photovoltaikanlage. Die Technik im Kellerraum, ausgestattet mit einer Batterie, ist sehr platzsparend und sauber montiert. Auf dem Dach fanden 32 Module von insgesamt knapp 60 m² Fläche Platz. Er erbaute die ganze Anlage mit grosser Fachkenntnis in kurzer Zeit. Seit Beginn weg läuft sie absolut problemlos. Christian Gyr erleben wir als sehr hilfsbereit. Bei Fragen oder Unklarheiten seitens der Bauherrschaft, kümmert er sich jeweils, ohne gleich jede Zusatzleistung in Rechnung zu stellen, klärend darum.
