Top Notch Service

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.

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

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

Thank you for taking the time to leave us a review - we’re delighted to hear that your installation went smoothly.
I understand that my colleague from our Technical department has already been in touch with you to get you set up on the app.
At the time of launch, our OHK Battery & Inverter app was temporarily unavailable on the Apple App Store, but we're pleased to confirm this was resolved quickly and the app is now fully accessible. All system settings and monitoring features are now available through the app.
If you need any further assistance, please don’t hesitate to get in touch.

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.

OHK SOLAR PANEL REVIEW

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.
Milo White.

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.

A year later and still delighted with our OHK Energy experience

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.

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.

Hi John, This isn’t how we operate and it’s not the standard we expect. I’ve passed this to the relevant manager to investigate.

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!
