Caldor Solar Avis 

excellent workmanship on the installation. really nice guys and very clean after they finished.
would recommend them .

Call out service when something goes wrong is useless. Last year I had an issue and it took several weeks before someone came out. I had just had it serviced and a week later it went wrong. It was not connected at all so it was costing me money. I had paid for service and then had to pay for the callout. I am currently without hot water. The boost unit is gone and I have paid out 250 for a new one but callout time is 10 to 12 weeks. I have no hot water. The immersion was disconnected when this was put in. If I hadnt an electric shower I would have no way of showering. I am totally disgusted with service. There should be an emergency team available when issues like this arise. It is totally unreal to think it cannot be sorted for 3 months. Totally dissatisfied with it.

Kamil is very professional and I am super happy with the company and their work. I recommend it to everyone!

Very Helpful experienced staff member Carl, helped with technical support in a warm professional manner. Went above and beyond with follow up calls to ensure that system was operating correctly and happy with service provided.

From our very first encounter with Kamil, the system design and subsequent installation, and then in the months that have followed, we cannot recommend Caldor Solar and their team more highly.

We were so impressed with their advise, their approach to us as customers and the integrity of their entire workforce. They informed and briefed us with great patience. They listened to our concerns and requests. They installed the entire system flawlessly, with their professional, hard-working and friendly team. They were so adaptable to the complexity of our own home.

What was crucial in our decision to go to Caldor Solar, was this: they had clearly listened to previous review issues and had found workable solutions. Their experience in Ireland really shows.

It is now 3 months since our system was installed and we are very impressed with it, performing exactly as we were told. The software ap is very informative and we are beginning to see some great results.

So a big shout out to Kamil and his team and to the staff at Caldor Solar. Thank you

Kamil is very knowledgeable and gave me assurance that all my needs were met. Caldor installed my panels last week, everyone was highly professional and corteous. Ivan wen't above and beyong to make sure all my concerns were addressed. Did a good tidy job in no time. I am very happy with how the install turned out. I highly recomment this team!

Install was fast and they fit a large number of panels on our roof. However, they contacted us a year later to say our system had been offline for three months and that they would need to come out and service it. We waited three more months for them to come out and they fixed the problem in 5 minutes. They said maybe the rain had caused the panels to overload (what??). Next year, we contacted Caldor to disconnect our panels for a roof repair; they took four (4!!) months to come out and do 30 minutes of work. When the roof was repaired, they said it would be another "few" months before they could wouldn't re-install the panels because they weren't sure the new roof would work correctly (huh?). We re-installed them ourselves and they're working fine.

From the get- go Caldor stood out from other companies we called and priced for a home system. After sales service, advice and general all round high quality product deserve an ‘excellent’ level review. And a recent battery upgrade has been flawless and excellent price/ value.

This review could go on forever but I’ll try keep it short.

We dealt with Cameron, he missold us a timeclock, we already had one. Had to have it removed from the quote. We also feel he misled us on lead times, with us having to follow up and complain in order to get a date for installation set in stone. It was eventually done after 14 working weeks, Caldor said it was 12 working weeks as they close for 2 weeks in August which was never advised to us. We were also told 2.5kWh battery would be plenty for us and our usage, it’s not.
We had many back and forth with the managing director trying to get it resolved or to refund us, they didn’t want to refund us the 30% deposit.

We brought up the black trunking on the outside of the house being the cheapest, flimsiest option and also that they didn’t install a fire board, just plasterboard. All of which Eoin, the managing director, without seeing pictures (we offered to send them on) said they were within regulations. Regulations or not, what else have they skimped on with the bare minimum in the install?

We advised Eoin the whole way we were not happy with the customer service and it would reflect our review.

Caldor were not the cheapest option by a long shot, but we went with them based on reviews / a personal recommendation.

Shoutout to Sarah in customer service though, she has been amazing with any queries I’ve had for her.

Overall, would not recommend Caldor and if we had the chance to do it again, we would go with another company. I’ve attached pictures of the trunking and plaster board the battery is sat on.

The system itself works perfectly.

I contracted Caldor Solar to install 14 solar panels at our new home near Dublin. After much consideration, I wanted to share my experience to help prospective solar panel buyers make an informed choice when selecting a company for their project.

The Positives
The initial consultation process was efficient and professional. A representative from Caldor Solar visited our property, assessed the roof using a drone, and provided guidance on the number of panels, layout, and expected energy output. The installation itself was completed in a single day.

Areas of Concern
Unfortunately, my concerns began with the placement of the inverter. It was installed in an unfinished attic, with all cabling laid directly on or embedded in the wool insulation. This decision significantly complicates any future attic conversion, making it impossible unless the inverter is relocated.

When I raised this issue with Caldor Solar, their initial response was that the installation complied with regulations, and they refused to consider relocating the inverter. While compliance is important, I believe a good installation should also account for practical considerations, such as maintaining property value and future renovations. Furthermore, Caldor Solar claimed that the inverter’s location had been agreed upon during the initial visit, yet I have no recollection of this discussion—something I am certain I would remember, given its significance.

Upon further investigation, I discovered that three other contractors working on identical homes in our estate had all opted to install the inverter outdoors to avoid the exact issue I encountered. After consulting one of these contractors, I was informed that placing the inverter outside was a deliberate decision to ensure future attic conversions would not be hindered—a solution that, in my view, demonstrated greater foresight and consideration.

Eventually, after persistent discussions, Caldor Solar agreed to relocate the inverter. However, they refused to cover the cost, meaning I had to pay again for a decision that, in my opinion, should have been made correctly from the outset.

Another concern relates to the external cabling. The flexible conduit running from the roof to the lower ground floor is of a very basic and inexpensive quality. On installation day, my wife raised this with the electrician, who verbally agreed to return and install a proper casing. However, Caldor Solar later reneged on this commitment, stating that they do not stock such materials. While this may be true, sourcing a suitable five-meter casing would have been a minor effort and a reasonable customer service gesture. The lack of willingness to accommodate even this small request was disappointing.

Notably, the other three contractors in our estate installed more aesthetically pleasing and better-protected cabling, making Caldor Solar’s approach stand out negatively in comparison.

Summary of My Experience
Pros:

Polite and professional staff.
Responsive to emails and phone calls.
Cons:

Poor aftercare service.
A reluctance to acknowledge or take responsibility for installation decisions, citing regulatory compliance as a defense.
Lower attention to detail compared to competitors.
I will leave it to prospective buyers to decide whether Caldor Solar is the right choice for their needs. However, I hope this review provides useful insights for those considering their options.
