The clarity of the technical explanations - much needed by this writer - and seamless installation from the courteous team was much appreciated.
Nothing was too much trouble with quick responses to any queries and the app impressive and logical even to this non techie mind.

 Trustindex verifies that the original source of the review is Google. We recently had Ecoefficient Solutions NZ install our new solar system and couldn’t be happier with the whole experience. From the initial consultation and advice right through to the final installation, the service was excellent. Communication was clear throughout, the team were professional and easy to deal with, and the quality of the workmanship is outstanding.

We were also really impressed with the quality of the products and equipment they use. The finished installation is extremely tidy and has been completed to a very high standard. It’s clear they take a lot of pride in their work.

We’re very happy with the system and wouldn’t hesitate to recommend Ecoefficient Solutions NZ to anyone considering solar.

 Trustindex verifies that the original source of the review is Google. We recently had a solar power system installed by Ecoefficient Solar and couldn’t be happier. The whole process was handled efficiently, professionally and with great communication.
As a novice, we’ve learned a lot about solar power and how to make the most of our investment. I would have no hesitation recommending and supporting this excellent local provider.

 Trustindex verifies that the original source of the review is Google. Exceptional service, great contact and communication.  Felt like what we were wanting to achieve was listened to and did not try to oversell us what couldn't be done, or we didn't need. On install days the team worked really well together and had good processes in place. We would be very happy to recommend Shaun and the team at Ecoefficient. Looking forward to learning our new Solar world :) Thank to Shaun, Laura and the team.

 Trustindex verifies that the original source of the review is Google. Shaun and the team have been absolutely amazing to work with. No question was too stupid, no issue was too small. From start to finish extremely happy with the solar set up we have. Looking forward to those long summer days now knowing that we are producing our own electricity. Local to Hawke's Bay was a big plus for us as well. Thanks Shaun and the team. Highly recommend Eco Efficient. 10/10

 Trustindex verifies that the original source of the review is Google. We are very happy with our system design and install.  Throughout the entire process communication was great and everything explained thoroughly.  Special mention to the install team who endured possibly the 2 coldest days of the year on our roof! The ongoing support available post install with meter changes and app help was a key in choosing eco-efficient and has been excellent.
