Our experience with Rockfrog has been outstanding. They had hurdles to overcome (we had a previous solar panel system) but did a phenomenal job getting our system installed and running. Customer service is exceptional! Our system has been running since March. We are now at the end of August and Zach has reached out to ensure we are happy and if we had any questions.

Daveand Evan from Rockfrog are Amazing! We have had Solar for awhile, but we needed an expert for the plan to hook it up to our new House/Church. They are detail oriented and stayed in close communication throughout the project. They also worked through a difficult time with the Power Company, but we're successful in achieving getting our 2nd inverter on. I would highly reccomend this group for your Solar needs!!!

Rockfrog was great to work with on our residential solar installation. They helped us design the system that met our needs. The installation was professional and smooth. Our system is performing exactly as we had hoped.
Response from the owner:Thank you Carol for the great review! We really enjoyed working with you to design a solar system around your home's energy needs. It's great to hear that the installation went smoothly and that the system is performing exactly as you had hoped. We put a lot of thought into making sure each system is properly sized and designed for the customer, so it's especially rewarding to hear that everything is working as expected. Thank you again for trusting Rockfrog Energy with your solar installation!

Had my a great experience with Rock Frog installing my solar panels plus batteries. Zach took the time to explain my energy needs. The crew was professional throughout installation. Would recommend them for any of your solar needs.
Response from the owner:Thank you Mike for the great review! It was great working with you on your solar and battery system. I’m glad I could take the time to go through your energy usage with you and help put together a system that made sense for your home. Our installation team takes a lot of pride in doing clean, professional work, so I really appreciate you recognizing them as well. Thanks again for choosing Rockfrog Energy, we really appreciate the recommendation!

Did a great job on a 33 panel 3 battery system. Good communication from Zack and it looks great. More importantly it seems to be generating about what we need and I am looking forwards to not paying Centerpoint as much. Folks it's an investment also. Rates keep going up and it also increases your home value.

Response from the owner:Thank you Don for the great review! It was a pleasure working with you on your 33-panel, 3-battery whole-home backup system. We put a lot of time into designing the system around your actual energy needs, so we're excited to hear that it's already producing about what you were expecting. We also appreciate you mentioning the communication and the finished look we take a lot of pride in making sure our installations are both well designed and cleanly installed. Hopefully that CenterPoint bill keeps getting smaller! Thanks again for trusting Rockfrog Energy with your project.

Rockfrog is amazing. Kudos to Zach for putting up with me! I had contacted him a year before I decided to actually do this and he still remembered me, updated my quote, and answered my millions of questions. He helped dial in what I need and helped me with all the stuff. The install team was fantastic, polite, and quick. I went with a battery back up and panels and so far its offset almost all of my daily use and its only been a few days. I would strongly recomend them for any solar project needs!

Response from the owner:Thank you so much Alex for the great review! It was a pleasure working with you, and I’m glad I could help you work through all the questions and options over the past year. We want every system we install to be designed around what the customer actually needs, so taking the time to get the right combination of solar and battery backup was well worth it. It’s awesome to hear that your system is already offsetting nearly all of your daily energy usage just a few days after installation. I’ll also pass along your kind words to our installation team, they’ll be glad to hear you had such a great experience. Thank you again for trusting Rockfrog Energy with your project!

Rockfrog was referred to us by our builder. Zach was incredibly knowledgeable about solar, batteries, panels, equipment, install and how to minimize costs while maximizing system value. He provided clear quotes, multiple options to chose from (depending on our specific needs) and clear breakdowns of energy costs versus what can be saved. Probably the best thing was his quote being truly “turn-key” which meant all electrical work, trenching (we had panels on the house and barn in our plan), and install is included in a single number. I didn’t quote around much, but using AI it was clear the quote was highly competitive. I don’t think you can go wrong with these guys if you’re looking for solar- good luck getting off the grid!
Response from the owner:Thank you so much for the detailed review! We really appreciate you taking the time to share your experience working with Rockfrog Energy. We believe in providing clear options, transparent pricing, and detailed information so customers can make an informed decision about whether solar is right for them. We're glad we were able to provide the information and options you were looking for, and we truly appreciate the kind words about our team and proposal process. Thank you again for considering Rockfrog Energy!

We had our system put in this past winter and are already reaping the benefits from it! All of our neighbors lost power awhile back and ours went on completely uninterrupted thanks to the batteries we installed. We also have already went from having a $950 Centerpoint bill to having a CREDIT with them this past month! As far as the service with Rockfrog, it was unmatched! We were highly impressed with everyone we came in contact with. They were extremely professional and helpful with all questions we had along the way. Even several months later if we have a question they are very quick to respond and provide support. If you are thinking of adding solar to your home I would highly recommend checking them out!

Response from the owner:Thank you so much Amber for the incredible review! We're thrilled to hear how well your whole-home backup system is performing, especially that your home stayed powered while your neighbors were without power. Seeing that kind of difference is exactly why we love what we do. It's also great to hear that you've already seen such a significant reduction in your electric costs and even received a credit from CenterPoint. We truly appreciate your kind words about our team and our continued support after installation. Thank you for choosing Rockfrog Energy and for the recommendation!

After getting tired of the cost of high electric bills, we started to look at solar options. Dave and Allen came to our home, developed a project quote and completed our project in a timely manner. Employees working to complete the project were polite and professional. We have not had any maintenance on our system. Our area has lost power since our system was installed and solar / battery backup kept our home running. The best part is that our electric bill has drastically reduced. Our lowest electric bill thus far has been 9 dollars. Going solar is definitely paying for itself. Would highly recommend ROCKFROG!
Response from the owner:Thank you so much Elaine for the great review! We're thrilled to hear that your whole-home backup system has already made such a noticeable difference in your electric bills and that you've been able to keep your home powered during outages. Reliable backup power and long-term energy savings are exactly what we aim to provide with our systems. We also appreciate you recognizing our installation team and their professionalism throughout the project. Thank you for choosing Rockfrog Energy and for the strong recommendation!

We started by requesting quotes from three solar companies. Two of them provided a response and estimate to provide solar and batteries for our house. Once we reviewed both quotes, we responded requesting that we not have any Tesla related equipment. Only Rockfrog Energy was able to work with us to meet our requirements for solar. We worked with them to refine our needs, and to better understand how our energy would be provided with the combination of solar and batteries. They are thorough and great to work with. They have good communication from the start of the project through the completion. They have followed up with us several times. Notably, they took the time to message all of their customers before the last snowstorm with information on how to ensure that the batteries are as fully charged as possible in case of an electrical service outage. These folks are top notch, and we appreciate the work that they did to provide us with a solar and battery solution that matches our energy needs.
Response from the owner:Thank you so much Bryan for the thoughtful and detailed review! We really appreciate you trusting Rockfrog Energy to design a whole-home backup system around your specific needs. We believe every system should be tailored to the customer, including the equipment that goes into it, so we're glad we were able to find the right solution for your home. We also take a lot of pride in staying involved after the installation, so we're especially glad our communication and follow-up have been helpful. Thank you again for choosing Rockfrog Energy, we truly appreciate your recommendation!

Response from the owner:Thank you Bryan for the great review! We're glad to hear you're pleased with the performance of your solar system and that our team provided a positive experience from start to finish.

I contacted Zach at Rockfrog and within four hours, he had emailed a plan and a proposal. In just over a month, the entire system was installed and working perfectly. If I have any questions, they are quick to respond to my inquiries. I highly recommend this company. On a side note, one of my friends hired another local company at about the same time and they are still getting excuses on why they have not started his project.
Response from the owner:Thank you Kurt for the great review! We really appreciate you trusting Rockfrog Energy with your solar project. We take pride in being responsive, keeping our customers informed, and moving projects forward efficiently, so we're glad that was your experience. It was a pleasure working with you, and we're happy to hear your system is up and running perfectly. Thank you again for choosing Rockfrog Energy and for the recommendation!

Full transparency...I'm an owner of Rockfrog Energy. We appreciate all the reviews here. We are blessed to have great people that do great work and the crew did a great job with our house. We designed and installed a Powerwall 3 system with an expansion battery and 16kW of solar in May of 2025. This was the first Tesla Powewall system we installed as a company. We wanted to install it and test it first on my home before we started installing them for others. We are an all electric house and we have paid $11.77 for each month since May (which is just the connection fee). Hope this information helps shed light on what is possible with solar and battery installed on a home.

Rockfrog did an amazing job installing my solar system! Dave, Zach, and Allen are super friendly and easygoing. They’re laid-back and great to work with. There was no sales pressure at all. They didn’t try to sale me anything I didn’t need or want. In fact, they suggested I go with a few less panels than I wanted. The software they used to analyze my property was way better than some others I’ve seen. The amount of data they were able to give me was the main reason I decided to go with them. I did a lot of research on my own before I contacted them, and I knew the equipment brands I wanted to go with. They had no problem with that. Some places only want to sell and install the brands they prefer. I couldn’t be happier with the system they installed for me. I chose to go with the Tesla Powerwall 3 with an additional Tesla DC Expansion battery, and Qcell solar panels. The system is even better than I thought it would be! I was their first customer for installing a Tesla Powerwall 3 after they got their Tesla certification and they installed it professionally. I highly recommend Rockfrog Energy for any solar application and installation!!! A definite 5 stars plus!!
Response from the owner:Thank you so much Tim for the incredible review! We really appreciate you trusting Rockfrog Energy with your solar and battery installation. We take a lot of pride in designing systems around what each customer actually needs rather than selling more equipment than necessary, so we're glad that came through in your experience. It was also exciting for our team to install our first Tesla Powerwall 3 after becoming Tesla certified. We're thrilled to hear that you're so happy with the performance of your Qcells and Powerwall 3 system. Thank you again for choosing Rockfrog and for the 5-star recommendation!

Our experience with Rockfrog Energy has been a pleasure. All the members of the team were knowledgeable, available to answer questions, and easy to talk to. Installation of our panels and batteries progressed smoothly and timely with no cutting corners. The entire process was stress-free. We spoke to two other local solar companies prior to Rockfrog and we were not impressed with their knowledge of their product or their desire to work with us on our project. The system has performed as expected. In the first full month of use (May 2025), we saved $223 off our energy bill. If you're interested in solar we highly recommend these guys.
Response from the owner:Thank you so much John for the thoughtful review! We really appreciate you trusting Rockfrog Energy with your whole-home backup installation. We're glad to hear the process was smooth and stress-free and that our team was able to answer your questions along the way. It's especially great to hear that your system is performing as expected and already helping reduce your energy costs. We truly appreciate your recommendation and are grateful you chose Rockfrog Energy for your project!

We have had a solar system with battery back-up by Rockfrog Energy for almost 4 years. It has been great having significantly lower electric bills and also having peace of mind knowing that we have a back-up system in case of power failure.  Rockfrog Energy was very professional, and they have great people working for them. You can know and trust a company by observing the way they handle and do things, and Rockfrog Energy is a very trustworthy company. They are the best!
Response from the owner:Good morning! Thank you for the review and the kind words. We also want to thank you for being a long-time customer. We're thrilled to hear your system is providing you with lower electric bills and peace of mind. Please let us know if there is anything else we can do for you.

Rockfrog gave us energy freedom through solar panels and a battery system. Our system has significantly reduced our electric bills and we've maintained electric when power was out for several days in our neighborhood due to ice and wind. In addition, we couldn't ask for better service from their employees. The peace of mind we have is priceless!

We absolutely love our solar system from Rockfrog Energy! We originally chose solar for the energy and cost savings, but also wanted the peace of mind that comes with having backup power. Last week, we lost grid power for 12 hours—and we never missed a beat! Our solar system kept everything running: refrigerator, hot water for showers, cooking at home—you name it. It worked exactly how we hoped it would. We also had a plug installed for an external generator as a backup to our backup, but we didn’t even need it! On top of all that, Rockfrog has really delivered a personal touch throughout the entire process. They’ve been incredibly responsive to any questions we’ve had—before, during, and after installation. It’s clear they truly care about their customers. Highly recommend Rockfrog Energy for their quality systems, reliability, and outstanding customer service. It’s one of the best decisions we’ve made for our home!
Response from the owner:Good morning, Holly! Thank you for the five-star review and kind words. We're happy to hear that the system was able to get you through the recent storms safely and without interruption. Please let us know if there is anything else we can do for you. We hope you have a great week!

We have had the Rockfrog Energy Solar/Battery systems at our Indiana home and our Florida home for 3 years. The savings have been substantial and the operation flawless. We were so impressed with the savings that we recently added battery capacity. The solar panels have stayed in place during hurricane winds in Florida and tornado winds in Indiana. I highly recommend the Rockfrog Energy System.
Response from the owner:Thank you for the five-star review and sharing the success you've had with the solar panels and added battery capacity. It's great to hear the panels and the system have been able to withstand Mother Nature. Please let us know if there is anything else we can do for you. Have a great week!

Let's Get Started!

At Rockfrog, our mission is clear: to democratize solar energy by making it accessible, cost-effective, and environmentally sustainable for the many, not just the few.
