We contracted Cole Diamond to install our 12kW Solar System in Beamsville, ON. It was a very pleasant, no issue experience. Diamond Energy is a highly professional and technical solid company. I can only recommend to call Cole Diamond to install your solar systems.Christoph Arnold

Great experience working with Cole and the Diamond Renewable Energy staff. Cole's attention to detail was 2nd to none. it was a pleasure working with DRE.

We had Diamond Renewable Energy install our solar panels in October 2020 - a 12.4kWp system on our roof. We were also having a metal roof installed at the same time which required coordination between contractors. Cole did a fabulous job communicating with the roofer and making life easy for us. The panels were installed on time and the work was top-notch. The customer service was excellent and we have high standards in this area. He was pleasant, professional and very helpful. He has also been very responsive to questions etc as recently as this past week...nearly 2 years after the job was complete. I have no hesitation recommending them for your solar installation.

Cole was a pleasure to deal with. He knows his trade very well and his re-install was professional and efficient. I am very happy with his work and have no problem in recommending his services,

Highest of recommendations!!!! From start to finish this company is the most amazing company I have ever had the pleasure of working with!!! they looked after everything and there was no stress at all in such a big project. My house included a complete roof replacement on top of the solar panel installation and they were on site almost everyday helping to ensure that both the solar and roof warranties would remain in tact. Day, evening and weekend total dedication. I would never go to another company!

Excellent group to work with for our 11kW net-metering solar installation with battery back-up system. Expert people, great products, fabulous responsiveness and service. Highly recommend Cole and his team at Diamond Renewables!

We hired this company to do our solar install and we are very happy. Cole walked us through every stage of the install and addressed every concern we had. There we no issues, no surprises. We are considering putting a second system in. If we decide to, we will be hiring Diamond Renewable Energy for that project.
