Aloha! I am whitney and i am heath and we are the proud owners of naughty cat farm and this is our RES success story. We saved our entire lives to finally buy our farm in South Kona. We are completely off grid. Solar was the obvious choice for our needs. We had never lived on solar power and were very over whelmed by the technologies available and the sea of installation companies to choose from. This was a steep learning curve with no margine for error. We could only afford one shot at this and we needed it to work the first time. We spent 8 solid months doing a completely exhaustive scrutiny of every single solar energy provider on island. We spoke to and met with everyone from the humble one man operations up to the largest company with the biggest fleet. At the end of the eight months of searcgi g it was 100% clear that RES was hands down the best choice. They have the most experienced technicians in all Hawaii. The father and son who run the company have technical working knowledge and credentials that rival NASA engineers. To that same end they are the only company on the island that is offering the latest in cutting edge technologies. From our first meeting on they were professional, transparent, and PUNCTUAL! They worked with us to determine our energy needs and quickly provided us with a list of options that would work for us and explained the technologies in a way we could understand. Their price estimate was clear, simple, itemized and very competitive. They also outlined exactly how much we would benefit from the huge state and federal tax credits! The installation crew was a group of extremely polite, intelligent and hard working technicians who obviously new what they were doing. They had the complete system up and running in less than 48 hours and left the job site cleaner than it was when they arrived. It has been 1.5 years now and we have not had one single problem! We have put the system to the test, powering our home and farm. The equipment is working perfect and completely maintenance free. I don't normally take the time to proactively write up reviews on companies who services i use. However, i am telling you right now. We did the hard leg work of investigating and researching every single solar company on BOTH sides of the Big lsland, and we chose the experts at RES. Do yourself a favor and call them before you make your final decision on who to trust with your money and your families safety. read more

My husband and I just bought our first home in South Kona. The property is completely off the grid and very challenging to access even with a 4x4. We spent many long hours researching all of the solar vendors and contractors on the island. We met with and received quotations from no less than six separate companies from both sides of the island. After our exhaustive search it was very clear that Renewable Energy Services was the best choice. Here is why: The President of the company Peter and his sons Roland and Tally are hands down the most knowledgeable, experienced and professional team we met. This was not their first rodeo. Roland helped us determine our capacity requirements. He made sure we had enough capacity that we did not set ourselves up to fail but did not try and up sell us with things we did not need. RES offers only top quality equipment and was the only company on the island that offered a new cutting edge battery system that is completely maintenance free. Roland's communications throughout the entire project where clear, concise and timely. We were provided with a detailed project proposal as well as a itemized cost sheet. The documents were easy to understand and outlined all aspects of the deliverables including installation dates and timelines. RES sent a crew of three trucks and eight men to do the installation. They showed up on time each day and worked very hard the full day through. The crew was professional, experienced, polite, patient and pro-active. The entire job was completed ahead of schedule and within the budget I was promised. The crew left our home just like they found it. When they arrived the home had no power of any kind and when they left I simply walked in and turned on the lights to find my easy to read wall display show me that my batteries were fully charged and everything was working just like they said it would. All that is left to say is: RES did an amazing job for us. They are easy to work with and very reliable. I have no regrets at all and would recommend RES to anyone looking to add solar to their energy portfolio. read more

Our experience with RES and their crew was exceptional. Their professionalism, enthusiasm and efficiency were above and beyond what is normally expected. Whenever possible we prefer doing business with local companies that help support our communities. Thank you Roland, Joe, Troy, Wayne, Jakon and Charles for your hard work, laughter and Malasadas. read more
