Tesla lithium solar battery installation.


The installation of the Tesla lithium solar battery system was completed in a little over a day and was mated to a roof mounted solar panel system previously installed by Igloo Environmental five years ago. Igloo Environmental staff handled the job with superb professional skill, the site was left in pristine condition. The company Igloo Environmental is a solid reliable business and we would highly recommend them to any prospective future clients. Well done lads 10/10

Faultless on all fronts


Following a recommendation by friends we contacted Igloo and were pleased to learn they covered Norfolk. Their surveyor was so professional and recommended a system of panels and a storage battery that was just perfect for our needs. The installation was faultless and carried out in one day. Their surveyor even checked that we were happy and the system was working as it should be while he was on holiday! Fantastic service and a brilliant price.

Professional, communicative and patient


The Igloo team installed a solar and battery system for us over the summer, having beaten the quotes we had received from a larger supplier. The project manager was communicative and helpful throughout and maintained the support when the inverter decided not to behave (we have a slightly atypical setup). The installation team stayed in touch and on the case until the system was up and running. I would happily recommend them to anybody.
