OHK SOLAR INSTALLATION

I had solar panels and battery system installed at the end of August by OHK From my initial contact with Gerard in sales right through to the installation the whole experience was seamless and stress free. The quote was competitive and the installation was professionally completed by Oisins and Shane, competent and understanding tradesmen. I am very happy with the service I received.

From first contact the experience was brilliant. From sales representative, James, very knowledgeable and answered every question, the roofer’s were very efficient and fast. 20 panels fitted in hour and a half. Tidied up after as well. Electricians were very good as well, nice lads and great at their job.
One small issue with the after care. It is being sorted today hopefully.
Zappi car charger and the harvi are not connected. Made a few efforts to solve it myself with prompts from companies but no luck. These things can happen but hopefully solved today.
Very happy with the system so far. 🤞

Excellent Service

Our experience with the sales assistant and installers was excellent. The installation of our 17 panels and 2 X 5kwh batteries was fast and the installers were careful when working on our property. They left the place in pristine condition. There was a small issue with connectivity between my phone and the App in the first few days but they returned promptly to replace the wifi dongle. Their app is very intuitive and informative. We are very happy with the installation.

Very poor communication within company- poor organisation. Sales rep does not know products they are selling and hence mis selling

To clarify, the battery installed is the same one that was included in your proposal and quotation. The installed battery is the Sigenergy SigenStor BAT 10.0. While the model's name includes "10.0", this is a product series designation rather than the battery's energy capacity. It identifies the battery as part of Sigenergy's 10-series modular range. The battery's usable energy capacity is 9 kWh, which matches the battery specified in your proposal. I understand how the model's name could cause some confusion, and apologies this was not clarified earlier.

OHKEnergy Solar Panels

The service from the Sales Rep was excellent.

Panel installers arrived on time, were very efficient and pleasent however they didn't sweep up and left small pieces of metal on the driveway.

The 2nd group arrived on time. They were very dirty workers, they drilled a hole in the bedroom ceiling/ wall and made no effort to cover anything and left plaster all over the bed and floor. The same thing happened in the hall when they drilled another hole.

They were unable to give any instruction etc. about the use of the app. They said they hadn't seen it before and told us to contact the technical department.Luckily enough we're both tech-savvy and worked it out for ourselves.

Lastly, they used the toilet and left it in a deplorable state. It was so bad we had to asked him to clean it up which was quite embarrassing.

I'm a bit disappointed with the app. I had to contact the Technical Department on two occasions as it was not working properly. Their response was good.

We chose this company based on a recommendation from my brother and based on my positive experience with the Sales Rep, I recommended them to a friend before my installaation took place. However due to the issues with the installers, we will not recommend the company to anyone else.

Hi, thank you for your feedback. We’re pleased to hear you had a positive experience with our Sales Representative and Technical Support team.

We’re very sorry, however, for the issues you experienced during the installation. The cleanliness of the work areas, condition in which your home was left and lack of app guidance fall below the standards we expect.

We completely understand your disappointment and have passed your feedback to our installation team for review. Thank you for bringing this to our attention and for giving us the opportunity to improve.

OHK installed 18 panels and 2 batteries for us over the summer. The process was seamless and we got an installation date 5 weeks after paying the deposit. Very happy with the installation just waiting to see how much we have saved on electricity. The app is easy to use and simplifies everything.

Run a mile

Run a mile. Do not use this company at all. Was told up to 8 weeks for install. After weeks of hearing nothing I called and was told an engineer needed to come out so i asked for a date. Weeks after that I rang again to find out when my install date was and they gave me one on the phone which was two and a half months after my initial deposit date. The scheduling team for this company are absolute joke. You need t odi all the chasing yourself. The day before install a truck turns up with a huge cherry picker and expects to just leave it on the road. No communication or prior arrangement from the company about this and as we live on a managed estate with allocated parking the cherry picker could not be left. Ohk are now refusing to do the install and it has now resulted in loss of earnings for my wife and myself. Ohk want me to arrange a different date with more loss of earnings and arrange with the management company to allow a cherry picker to remain in the estate for up to three days.
The installation manager on the phone was absolutely useless and kept blaming me for everything.
I would give these a negative score if possible

Follow up to reply. You offered no alternative date so gets your facts straight. You told me to find a date a cherry picker could be left and to get back to you. I got automated emails through the process. Not a single call from your company, I had to make all the calls to book engineers and an install date.

Hi Robert, thank you for your feedback. We’re sorry that your experience did not meet expectations.

We would, however, like to clarify that communication was provided throughout the process regarding the progression of your installation, and you were advised that a cherry picker would be required due to the property being three storeys high.

We do acknowledge that we should have made it clearer that the cherry picker was due to be delivered the day before installation, and we apologise for this communication oversight.

Unfortunately, when the cherry picker could not remain onsite as required, the hire company was unable to redeliver it early enough the following day to allow our team to safely complete the installation within the scheduled timeframe. As a result, the installation could not proceed as planned.

When an alternative installation date was offered, you instead requested cancellation and a refund, which has now been processed.

We regret the inconvenience caused and will use your feedback to improve how specialist equipment requirements and delivery arrangements are communicated to customers in advance.

I had an excellent experience with OHK Energy. From start to finish they were exceptional. The sales rep advised us on our needs and requirements. After this the communication was excellent. The panels were fitted in a morning and the following morning was wired up and we were up and running. The app was explained and every engineer was so pleasant. I would highly rate this company. One of the best companies I’ve dealt with for efficiency and quality of work. Delighted with our solar panels.
