What Our Client Say

Here’s what our clients say about working with us.

Installation completed promptly and as per schedule without any delays. Being a busy office, we were very appreciative of being asked when was a suitable time for any noise or disruption, and often worked around various meetings and room availability.

Very fast and efficient service. The process only took 6 weeks from my initial enquiry to having a working system fitted and producing solar power. Installation was handled by professional and friendly fitters who explained the whole system to me.

We contacted them about a solar and battery system and they replied within 24 hours. Good clear explanation of what they would do and they helped us with our concerns about solar panel pro's which was excellent. Friendly manner and after sales support is fantastic. I would highly recommend Solent renewables to anyone that needed solar
