The Good

  • Full-Service Solar Installer
  • Solar Battery Solutions
  • EV Charger Solutions
  • Solar Diagnostics and Monitoring
  • Solar Repair and Replacement Services
  • Free Solar Quote

Full-Service Solar Installer

1Solar prides itself in being a full-service installation company, meaning that the company will oversee and handle all aspects of the solar installation process from permitting to post-installation monitoring. Some solar installation companies outsource work to third-party contractors, allowing them to have a wider geographic reach to serve more customers, but often at the cost of efficiency; the more parties that are involved in the solar installation process can result in miscommunication, which can slow the process down significantly.

In addition to a more efficient solar installation process, the fact that 1Solar is a full-service installer offers several other benefits, including the following:

  • Seamless experience — 1Solar handles everything, reducing the complexity and stress often associated with coordinating multiple service providers.
  • Single point of contact — 1Solar customers have a single point of contact throughout the entire project, simplifying communication.
  • Quality control — As a full-service company, 1Solar maintains control over every step of the process, ensuring consistent quality standards.
  • Integrated services — 1Solar provides integrated services including site evaluation, system design, permitting, installation, and interconnection. This integration can potentially minimize delays and the chance of miscommunication.
  • Streamlined permitting and approvals — 1Solar handles all the necessary paperwork and interactions with local authorities, utility companies, and other regulatory bodies.
  • Customized solutions — 1Solar can provide more customized solutions tailored to the specific needs of each customer.

Solar Battery Solutions

1Solar offers solar battery services as part of their comprehensive solar energy solutions. These services are designed to complement their solar panel installations, providing customers with greater energy independence and resilience.

As a licensed installer of Tesla Powerwall, Enphase, SolarEdge, and Fortress battery backups, 1Solar ensures high-quality products that can assist you in taking advantage of excess energy generated by your solar panel system. This excess energy can be used to power your home at night when your solar panels aren’t generating power, or in the case of a power outage.

It’s worth noting that 1Solar is also a WattSmart partner, providing you with the opportunity to take advantage of the WattSmart battery rebate.

EV Charger Solutions

In addition to its solar system and solar battery installation services, 1Solar offers EV charger solutions and installation services.

There are many types of EV chargers available in the market and 1Solar can help you choose the best one for your home and vehicle. 1Solar’s team of licensed electricians can install EV chargers from Tesla, ChargePoint, Autel, Lectron, and more. 

It’s important to note that 1Solar EV charger installations are done by licensed electricians. The EV charger installation process can be complicated, including specific permitting and paperwork, but also requiring specialized electrical work — most EV chargers require heavy gauge wiring running between your service panel and EV charger, and it’s important to ensure that all wiring is completed by a professional electrician.

Solar Diagnostics and Monitoring

Once your 1Solar solar system is installed, you’ll want to make sure that all components are functioning properly and that your system is consistently operating at peak performance. To assist in system monitoring, 1Solar provides an app through which you can monitor your system. If you notice any system issues or errors through your app, you can contact 1Solar and a company technician will work with you to diagnose error codes and fix your system.

Solar Repair and Replacement Services

1Solar has a specific solar service and solar repair department that can help any customer, regardless of whether or not you’re a 1Solar customer. When you call 1Solar for repair and/or replacement service, a member of the 1Solar service department will be sent to your home to diagnose your system and determine next steps to get your system back up and running. If possible, 1Solar’s technicians will fix electrical problems on the spot; however, some problems may require more time and/or resources.

Free Solar Quote

1Solar doesn’t provide any specific service pricing on its website. However, because the company is a full-service and integrated installer, you may be able to secure competitive pricing, especially when compared to larger solar companies, such as SunPower or Tesla.

If you’d like a personalized estimate of your solar installation, you can request a free quote on the 1Solar website. Your price quote is subject to change, but it can provide you with an idea of what type of budget you’ll need for your solar project.

The Bad

  • Limited Service Area
  • Availability of Advanced Technologies
  • Solar Installation Speed
  • Limited Warranty and Financing Information

Limited Service Area

1Solar is a solar market leader in the Mountain West and currently has service areas in the following five states:

  • Arizona — Phoenix, Tucson
  • Colorado — Colorado Springs, Denver, Fort Collins, Pueblo
  • Idaho — Idaho Falls, Pocatello
  • Nevada — Las Vegas, Reno
  • Utah — Logan, Ogden, Farmington, Orem/Provo, Salt Lake City, St George

As noted above, 1Solar’s service area doesn’t necessarily cover all areas in all states listed above. Thus, it’s important to confirm whether or not 1Solar services your area of residence. Unfortunately, if you don’t reside in any of the states/areas listed above, 1Solar’s services may not be available to you.

Availability of Advanced Technologies

While 1Solar offers high-quality solar panels, their range of advanced technologies like battery storage and smart home integration might be less extensive compared to industry leaders like Tesla or SunPower. Customers looking for the latest in solar tech might find 1Solar's offerings somewhat limited.

Solar Installation Speed

A 1Solar solar project, from consultation to system activation, can take approximately 90 to 120 days. Compared to the industry average speed of 30 to 60 days, 1Solar has a significantly long installation timeline. It’s important to note that no matter which solar company you work with, timelines will vary and you could experience delays. However, 1Solar’s installation timeline is much longer than you may see with other companies in the industry.

Limited Warranty and Financing Information

1Solar doesn’t provide any warranty or financing information on its website, making it difficult to know whether or not you might be able to afford a solar system installation and what kind of protection your system would have.

1Solar does indicate that warranty information is provided on the purchase and installation agreement, but it can be helpful to have that information upfront. In most cases, solar companies offer 25-year warranties that typically include coverage for equipment and workmanship.

It’s unclear which financing options are available to 1Solar customers. Common solar financing options include outright purchase, solar loans, solar leases, and power purchase agreements (PPAs).

The Bottom Line

When compared to other solar companies, 1Solar stands out for its customer-centric approach and competitive pricing. Companies like SunPower and Tesla might offer more advanced technologies and wider geographic coverage, but often at higher price points. 1Solar's transparency and quality installations make it a strong contender, especially for customers prioritizing affordability and service quality over the latest technological innovations.

While there are areas for improvement, particularly in increasing solar installation speed and providing clearer warranty and financing information, 1Solar's strengths in customer service, pricing, and installation quality make it a viable installer option in the solar market.

Steven McIntyre

Rather than save money, I chose to go big with a system that provides 150% of my power, as well as batteries in the garage, and a SPAN panel to manage power draw during an outage. The install was an excellent adventure, but 1 Solar navigated the permits and inspections for me, so it was pretty smooth sailing. There were a couple of bumps, but nothing that they couldn't iron out in a timely manner. The install crew was amazing, and made sure that everything looked good, and worked well. I was always advised of what the next step was throughout the process, and I even got AC installed as part of the deal! The system looks good, and works great. I've exported 563.8 kwh so far, which will cover snowy/cloud covered days. We've also kept power through 3 power outages so far, and I couldn't be happier.

Reps were always available and returned communication quickly. Our project was delayed for quite a while (not 1solar’s fault) and we ended up having to start payments for the solar system before it was installed. The point of installing solar was because the solar bill would be cheaper than our electricity bill, so paying both at the same time was rough.

We have two houses that we want solar on. Our primary residence is in Golden and we have been on-line with our solar system there for two months now. The whole process was smooth, supported by communication and professional crews. We are moving forward on the other house now. Solar1 has my full support.

The installation was reasonably timely, the crew was polite and expeditious on the days they were present. The apps to monitor the system are fairly self-explanatory. It is reasonably easy to get in touch for customer servive if it is needed.

The sales member, Alex T, was very informative and was able to answer all my questions. The team that handled all the permits and paperwork took the burden off of me so I could work my regular job and not devote a bunch of time to setting this up. The installation team was respectfully of my property. So far I’ve had the solar panels up and working since March and have had a zero $ Xcel bill!

The install went smoothly and very timely. Everything happened when we were told it would happen. Everybody that we worked with was very nice and knowledgeable. We haven’t had one issue with the panels. We needed something updated for the app to work appropriately and that was taken care of and the app works great!

I wish 1solar was my first contact with solar companies. My first company, lumio, was great at first and got my back panels put on and working quickly, but 1solar was even better with my front system, and they are the ones who actually got my electric bill down to $0.00! Polite and professional all the way through the process!

I have rated this company 8 as I overall had good experience with a couple of hurdles. Needed some paperwork which took me two days to get those but ultimately I received it and had a smooth installation. So far I have been able to reduce my bill from $200.00/ month to $130.00 now. Hoping to reduce more in the future. I would highly recommend Onesola,

Stay vary far away from this company. The installers missed 60% of the truss anchors that hold the panels to the roof, On top of that they LEAK. They have no workmanship warranty at all. If you read this and still work with this company. YOU DESERVE EVERYTHING COMING TO YOU. ALL OF IT. THIS IS A REAL WARNING TO HELP PROTECT THE CONSUMER. Check out every review of every company you get quotes from, and do it in front of them and talk to them about it. Then you'll know the real P.O.S. sitting in front of you or not. Good luck for you all, your gonna need it.

Don’t do it, Don’t do it, Don’t do it! This is by far the worst experience with a company I have ever had. I’ve been dealing with solar1 since April… solar panels still not operating and it’s September! I’ve talked with several customer service reps, Michelle H and Matt S and still NOTHING! Nobody can give me answers! This is ridiculous. I’m about to start paying through my loan and panels are not operational….. Again since APRIL. The absolute worst communication. My friends and neighbors went with other companies and as an average they had their panels up and running within 4 weeks. Not solar1….we are going on 5 months!!! 100% unacceptable! Do not go with 1solar! If I could leave negative stars I would.

Disappointed customer Las Vegas, NV

This company is an absolute deceiving nightmare! I would never ever use them if I had the opportunity again! It started off with their sales person Craig S., he came off as the best guy in the world, turns out he was the biggest liar in the world! They tell you that you are going to get a ton of money back from your income tax return because of the solar panels... Which is part of their trick to lure you in...& in reality you don't even get a 10th of it back! When they installed the solar panels... They literally broke over a 100 roof tiles, They refused to replace all the tiles that they broke even though I had surveillance cameras on my house in it shows them breaking the tiles! They failed the 1st city inspection.. They are the worst company I have ever dealt with in my life! If you getting solar panels beware! And now I'm looking at the submit button for this review, and the only option is to hit the word amazing! So just info for you... I do not find this company amazing at all, it's just another one of their tricks!

I have not see any change in my electric bill. I honestly do not believe my pana S were installed properly . It’s that or they didn’t install enough panals for my home. Also it harder for me to get someone to respond to me in this issue. So now I am paying for an install that doesn’t even work so to make a long story short instead of savings all I have done is add another bill to my already financial low status.

They keep dropping the ball over and over again forgetting to schedule me. The build has been completed since January and they forgot to schedule the final inspection. They finally got the final inspection done 2 weeks ago and it failed. Haven’t heard from anyone about getting the electrician out to fix the problem. I signed nearly a year ago. This is a joke.
