The entire process, from the representative's visit to the actual installation of the solar panels, was smooth and hassle-free. The installers arrived on time and completed the job in just a few hours.

If like me you are looking to reduce the cost of energy and go green, then give Celtic Green a call. Quoted a reasonable price in a reasonable time. Fitted the system professionally and now my electricity bill has plummeted.
