The service from the first call to the site visit and to installation was top notch. It was all very professional while also being focused on what we needed. I really appreciated the safety aspects the day of installation too. The final installation was neat and tidy and you would hardly notice it was there, the panel team and the electrician talked us through everything beforehand to make sure we were happy with it.

Fast professional installation of highly efficient solar panels abd batteries...for a really competitive price! Many Thanks.
Sales Technician Tommy who assessed the house prior to installation was Excellent: In and Out in 30mins, and, unlike several other companies, there was no bs from him.

I purchased 16 panels and a 5kw battery. Overall, not very happy with the result. It took three visits over six weeks to install the panels and five months before the App was working properly. I'm still not convinced the panels are connected and registered correctly as the electricity yield seems very poor. My bills haven't changed. They are very poor in after sales service.

Top class professionalism from all involved, Sales, Grants, and Installers.
Communication and information packs provided timely and user friendly.
15 panels, 9kW battery, EV charger installed in one day.
Very easy to set up App mySigen with my tariffs, and allow AI mode to work out the optimum use of battery, and export.

Really good from start to finish. No real issues or hiccups at all. Very good communication and process.
Just note that if you go with the OHK battery and inverter you have to use a website to adjust battery settings and view status etc not an app. It’s a little annoying but once you get logged in it works very well.

There is an App now for the OHK branded equipment now, I received a call about it which was great.

The panel installers and electricians showed up at the stated times and were safely equipped, fast and left everything very tidy. Very happy with the installation overall.

Top class installation workmanship and panels working very well

From the first visit from Mark Whelan to assess suitability and advise which system would work best for us to the site visit and installation we found the whole experience stress free. No problem contacting Mark for advice and clarification on any issues. Total professional. The installation of the system was seamless. Was particularly impressed with electrical installation, as they fitted a sub board beside outdoor meter which meant all of system is outside the house. Really neat and professional work ( and I am quite fussy). Then app. takes a little getting used to, but a phone call to OHK sorted out any questions I had. Not the cheapest company in the market, but not the dearest either. You get what you pay for. So far so good. I am confident their after sales serve will be as impressive ,if required. I have no connection with this company, this is an honest review of my experience with them.
I would highly recommend them. I had four different companies quote for the job, and I feel I chose the right company.

Very good and efficient installation team supported by a very responsive sales professional. They optimised the space available on the roof, the installation was clean and quick.

Registered interest on the OHK web site. Got a call from a guy a week later arranging to do a call. Organised to speak with him the next day at 18.00 and he never calls. Waited a further week and no call back. I moved on with their competition in the interim. Very poor customer service.

It's been a year now since Ohk Energy did our home energy upgrade. We are absolutely delighted with the results. The Solar Panel team were fantastic and had everything done in 2 days. The triple glazing windows and doors from Senator Windows are of the highest quantity and they were a great company to deal with. Attic insulation was perfect and completed in a few hours. RTS did the radiator replacements and Heat Pump installation and were absolute professionals and a pleasure to deal with. Having the team at Ohk Energy organise all of this and the SEAI grants under the One Stop Shop scheme made all of this seamless. We couldn't be happier with the whole experience and would highly recommend it. The difference to the comfort of our home and our energy bills has been huge.

Good communication, kept to deadlines, nice staff.
However we are still waiting for the app to be activated.......

People didn’t show up on time our days there were supposed to. No engineer showed up he said he did and looked through the window that’s not really acceptable.

Very good service from start to finish, kept informed every step of the way. Installation teams were on time, efficient and very neat. After sales service was excellent. Highly recommended.

You did evberything that you promised at the times that you promised. The lads who put up the solar panels were super efficient and professional and two days later two excellent electricians arrived. They worked a full day with minimal breaks and did an exceptional job.
Your pricing was good. Your agent was helpful and all in all.... top marks!
