Report
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

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.

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

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.

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!

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
