Roland and his team at Renewable Energy Services, Inc. (RES) have earned my trust for reputable work and service. When installing my system a decade ago, I selected RES from among other cheaper companies because of the design/installation details they implemented that stood out from their competitors. I am not interested in cheap. I am interested in performance and quality of work and service. When manufacturing defects in the solar panels compromised the operational integrity of the system, they did their best to satisfy me at their expense, even though the fault was with the solar panel manufacturer. I recently replaced the faulty solar panels with new panels, again relying on Roland and his team at RES to do the job. I would not have had it any other way as RES has earned my complete trust as a company that will do things the right way from the start, and continue that promise and practice for years to come. It comes down to a single, simple word. "INTEGRITY". And RES exemplifies it!Daryn

I have researched and spoken with all the companies who do business in the Kohala region of the Big Island. RES is without doubt the best at recommending robust reliable equipment. Moreover their service is prompt and professional. They are the standard in this community.

We contacted Renewable Energy Services to replace our envoy solar monitoring system. Not only did we get extremely quick service, but the professionalism of all the employees with whom we worked was outstanding. We had choices of different companies that provided the same service, and we are so happy we selected Renewable Energy Services. We highly recommend this company!

We had an off-grid project collapse before installation when a lower-priced vendor ran into business difficulties. RES stepped in, took over the permit, and showed tremendous flexibility in getting our project re-started, with an improved design. They have been, start to finish, knowledgeable, easy to talk to, easy to work with, and thoroughly professional. They do what they say they are going to do, when they say they are going to do it, and the crew have been nice people to have around. They don't publicize themselves aggressively, but if you've found your way to them, you have done very well.

RES replaced an older solar setup with new classier panels and upgraded equipment. We couldn't be happier with the results. The system meets our needs well and the batteries charge very quickly. The best part was dealing with a team of true professionals that know their business and deliver a great product. Excellent communications. No BS. No surprises. And they have a reputation as the best on the island. Give them a call.

We had our first photovoltaic system installed by RES 23 years ago as we were building our home. At that time we didn't even have a roof on which to install solar panels. Having never lived off grid before, we were very pleased over the years with their continued support and advice.When it became necessary to update our system, from the initial assessment by Roland, to the presentation of contracts by Joe, and the accounting support by Diane, we found all arrangements to be made with professionalism and compassion. ALL our questions were addressed and answered completely.When the time came for installation, everything was handled with efficiency, and the utmost consideration. They were on time, respectful, listened to our questions, were as concerned about aesthetics as we were, and went above and beyond to make certain everything was installed the best it could be. It was quite obvious the professional team of installers worked very well together, enjoying what they were doing as well as each other. Charles, the electrician, handled hooking everything up even better than we thought possible. These people really know what they are doing and explain everything as well.We are amazed with the technological advancement of our new system and are so pleased with its efficiency and ease of operation. We highly recommend RES...you will be thrilled with the results.

Purchased my entire Solar Electric Panel system from Renewable Energy Services, Inc. several years ago, it works great! Now I'm seeking to add panels because of my higher electric consumption due to addition of A/C units in the house. My inquiry was promptly answered and I appreciated that.B. MooseHonokaa, Hawaii

We have worked with Renewable Energy Services on two projects at our home. Initially, we installed photovoltaic panels and recently we installed a backup battery system. These systems are not inexpensive; however, they are the prudent thing to do, especially while there are State and Federal energy tax credits available. Roland and his team were very professional, and thorough during the planning, design, permitting and installation phases. Their work crews are courteous, knowledgeable and very efficient in getting the work done. We wholeheartedly recommend that you give them an opportunity to work on your next energy project.

RES installed a grid tied self supply system on my home on the Big Island. They did a fantastic job managing all aspects of the project while I was off island. The quality of their install work was excellent. One of the panels had a rare manufacturing defect which revealed itself after the installation. RES responded by replacing the panel, despite the logistical challenges of working during the pandemic.This is great local company, and I would happily do business with them again.

I received a prompt reply to my initial inquiry..They provided good information about lithium batteries in an understandable form. Prices were right on with prices from the manufacturer and installation was reasonable. They also removed and recycled my lead-acid batteries the same day at a reasonable cost. They have answered all of my followup questions promptly and thoroughly. The crew arrived on time and worked efficiently even while answering my questions. They are knowledgeable as well. The accounting department was very efficient and timely. I can highly recommend Renewable Energy Service for solar installation. Our system is off-grid and providing all our energy needs.

Renewable Energy FAR exceeded our expectations! From our 1st inquiry to the completion of the project, the team was so incredibly helpful, responsive and knowledgable. Joe answered all our questions, helped us make a good decision for the long term with our solar needs, and got back to us immediately each and every time we had a question. They finished our project ahead of schedule and communicated throughout.The office staff was courteous and treated us like family. We spoke with 5 different solar companies and none were even in the same league with RES. Thank you! I highly recommend!
