I spent a bit of time trying to understand my solar pv, storage, immersion and backup options and contacted a few companies for advice and quotes. 21 Degrees were by far the most responsive and helpful to get a quote for what was a reasonably involved install. They scheduled the work and we worked through a battery supply chain problem. The install was quick and mostly snag free. The system was up and running next sun rise. I highly recommend 21 Degrees.

Battery system and inverter installed in a day. Its use during August and September reduced my electricity consumption by 90%. Nice people, quick installation, fantastic performance.

I wanted to leave a review for 21 Degrees after they installed a solar panel and battery system at our home. The team was a pleasure to work with from start to finish. They were professional and thorough during the planning and surveying stage, and the installation process was seamless. They arrived on time and the workmanship was impeccable. We are extremely happy with our new solar panel and battery system and highly recommend 21 Degrees for anyone considering solar
