From the initial consultation with Suzie and David to the helpful updates and answered queries from Suzie (at any time of the day) right up to and including the fitting I couldn’t fault them.
The fitting service from John and Fergal was excellent. Their work was really neatly done, both on the electrical side and the panel installation side. Both absolute professionals and very much passionate about their work. They make their job look easy but they work really hard. I was having issues getting a roofer after the storm and Fergal really helped me out by repairing broken tiles.
I am over the moon with the install and look forward to the savings for the years ahead.
I would have absolutely no reservations whatsoever in recommending start solar to anyone looking to install a new solar system to their home or business. A great example of fantastic customer service .
On the day of installation, the team was punctual, efficient, and very courteous. They worked diligently to ensure everything was set up properly, and it was evident that they were highly skilled at what they do. The entire process went smoothly, and the team made sure to keep me informed every step of the way.
What truly stood out was the amazing customer support after the installation. The staff at Start Solar made sure everything was working perfectly, and they were always available to answer any follow-up questions or provide assistance whenever I needed it. It’s rare to find a company that offers such high levels of service before, during, and after installation.
I highly recommend Start Solar to anyone looking for reliable solar solutions. Their professionalism, expertise, and commitment to customer satisfaction really set them apart from other companies in the industry. Thanks again to Andrew and the whole team for making this such a pleasant and stress-free experience!
We got a survey done, with suggestions as to the layout of the panels and position of inverter, battery and car-charger. Everything was clear and well presented. The prices were very competitive. I went for 5kW of panels and a 5kWh battery. The installation was fast, efficient and neat. They sent a team of two men - one is a roofer who fits the panels, and the other is an electrician. I had recently had our house re-slated, so I am a bit precious about my roof, but I needn't have worried - the guys clearly know what they are doing. Minor snags were rectified quickly and the response to any emails or phone calls was quick and useful. As for the system itself, the performance appears to the spot on. I was particularly attracted to the fact that the inverter, battery and car-charger are all the same brand (Givenergy) - so they work well together and are all in the one app. There is also a very good web app. The car charger seems good too - once set up correctly, you can plug-in for excess solar power to top up your car, leave it plugged in to charge overnight on off-peak rates, or tap the key-fob to charge immediately at max power.
Overall, I am very pleased with our installation and would not hesitate to recommend Start Solar.
All work was neat and tidy and the workers were excellent. I have no problem recommending Start Solar to anyone considering installing renewable energy.
