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.

All the workers from Celtic were very professional, polite and clean workers when installing our Solar Panels. The electrician who worked in the house wore overshoes whenever he came indoors.
