Testimonial's from our Customers
Just had solar panels fitted by Onboard Solar- absolutely brilliant service from start to finish. Great to speak to on the phone, quick to reply and Gary the fitter was fantastic- so professional and knowledgeable and really friendly and funny. Thrilled with it - amazing customer service at a very good price and would 100% recommend!
Was great to have my 640W system installed by Garry yesterday. He drove down from Nottingham to the K&A and was on task from before 09-00 and finished before midday..! Great thorough service and I thought a very favourable price too. I have become since then an avid watcher of the readouts on my new control box (yes I am a geek!)
