OTI was punctual and attentive during the quotation process – didn’t harass us but returned all calls. We were unsure as to whether we needed micro-inverters or optimisers and they did a great job in explaining their recommendation; in person, not just by phone/email (we went with optimisers). We were happy with the quality of all materials they used. Installation occurred on the designated day, without dramas, and the team were great; obviously knew what they were doing but asked appropriate questions as they went. Wiring was really tidy; panels worked immediately as per the app, which we love!
