Best Businesses in Arizona

Working with Semper Solaris was a pleasure. Dennis walked us through all our options for the system. He made everything very understandable and let us know what to expect every step of the way. The rest of the Semper Solaris team also communicated very well and kept us updated on the project. They handled all the paperwork and made the entire process very simple.Thank you Dennis and the Semper Solaris team!

As a techie who is HVAC savvy, I was impressed when Dave the sales representative arrived at my house to do his estimate. He spent 3 hours taking measurements, crawling in the attic, and running tests. He was the only Rep out of the 3 estimates I received to take this much time and effort. Then he took all his data back to the office and crunched the numbers before returning with his estimate which was significantly higher than his competition. He recommended higher end equipment with a 10 year warranty on parts and labor.  We set an appointment for the following week and when the installers arrived, they went right to work putting down heavy runners to protect my carpet, and got straight to work removing my old equipment. The house was just beginning to cool down as my wife returned from work. The installers were both friendly and knowledgeable, and it was a joy having them in my house. Dave also made sure that I got the forms for the rebates from my electric company. They were terrific!

I was having trouble with pigeons nesting under my solar panels, really glad I eventually found this company. Tyler was very professional to deal with, carefully explained the different services he provided and their prices, and did excellent work getting rid of the birds, setting up barriers to prevent them from returning, and cleaning the panels. Would definitely recommend.

Everything about my dealings with the Nergy team from start to finish was helpful and informative. I didn't realize how big of a decision I was making upon first interest into solar and these guys were awesome in answering all my questions honestly and thoroughly.

Great people to work with job went well and all the crew doing the install did a great FAST job.

I talked to Shane on the phone and he got me set up with an appointment within 5 mins! Next thing you know they were at my house. This company has been helping save money and time, and i value both of those things!

Great company--say what they do and do what they say. Very professional and polite electricians. We did a service panel upgrade along with some circuitry. So far, the work is excellent. We are going to contract with them to a a full ground-based solar upgrade.

Great company to work for just make sure that before you get your sign on bonus they have a chat with you about what you need to do for that they didn't do that with me and I got cheated out of my $500 sign on bonus which I was very furious about they don't pay you drive time or overtime the staffing is amazing they're great people they pay for your schooling which is great but as far as working for them I don't think I would recommend it or make sure you have tons of solar experience before you do

Being that this is the busiest time of the year for RV service, I found D & R's professionalism unmatched by most big shops in the Phoenix area. I had options as many of do, but if you want a boutique shop, this is the best option. Basically, Ron-owner, makes it a point to personally review and quality control the overall service. To me, his genuine interest to deliver the highest level of service and quality is my experience. I highly recommend this shop...

Kayo Energy installed the solar panels. Extremely professional, and provided valuable information.

Update- with all do respect, everything you've listed below with your response is incorrect but thx for your feed back.
The most important scenario is cust svc especially a NEW cust and existing.
Never the less your rant is incorrect, I've left you a VM as you did me while I was working as you are now closed~ no one is being non responsive, I'll await your contact @ the Oregon/Washington number that is valid. Not everyone moves and changes their contact number.
We've relocated a company to help us with our owned solar needs on the home we own in Maricopa.
Thx you for your CEO/Owner addressing the matter so promptly and professionally, us customers even NEW ones that are not in your data base appreciate it.
This person, myself is not fraud however if that is what makes you feel as your addressing this situation as a company professionally SO BE IT.
I'll await your professional contact, thx again

Thx Diane, I'll be calling another company thx to you and hanging up on me then dening that you did so.
Go on vacation, their are plenty of ppl looking for employment and would be happy to have your position, RUDE
To think I called you first because you had almost 5 stars google but Yelpers feel otherwise smh~ don't allow me to interrupt your day or whatever you were doing with a new customer inquiry

Years ago Heliocol put solar hot water and pool solar on the roof. I was later told they should not have sold me the water heater solar, as I was on gas and the backup for their system is This will be in parts in Twitter due to limited number of characters.

Years ago Heliocol put solar hot water and pool solar on the roof. I was later told they should not have sold me the water heater solar, as I was on gas and the backup for their system is electric, much more expensive and reduces significantly any savings.
Five years ago all sort of green material coming through my faucets, shower heads ruined and all had to be replaced. Big expense I paid. Found out the rod in the tank completely disintegrated. Likely due to the hard water in AZ, but they should have known this since they are in AZ. Anyway, put in a different rod and seems to be fine.Told me to service every 4-5 years. I have called and left messages for service to call me back twice over the last ten days and sent an email request for service. Never even the decency to call me. Finally, reached Melody last Friday, explained the situation and she "promised" to get back to me Monday to arrange a service call. She never called, I called and left another message and still did not have the courtesy of calling me back. Do you really want to buy their products and not be able to get them serviced?
Horrible company!
In regard to the solar for the pool. Over time the small tubes spring leaks. Bad for the flat roof and the elastomeric coating. Each time I would call for a repair it would take two to three weeks for them to come out. In the meantime I had to turn off the solar so it did me no good. Finally, went on the roof with my pool guy and learned how to repair it ourselves. Stupid of Heliocol, now they lost all that money which I gladly paid when they did come out.
The company is horrible, they sell you things they should't, they don't return calls or come out to do the necessary service. ZERO STARS. Need I say more?

If this is posted they are really stupid and really don't care about their customers, since I was nice enough to send a copy of the above to their main office with a note to please have someone of a managers level or above call and rectify this situation. I have given them a week to respond and they must have decided not to......

The system was installed, after long delays on May 2021. It stopped generating power by the end of July. Requests for information from the company have been ignored. They and their subcontractors simply do not communicate at all with customers. I've called several times and received promises of callbacks with followup information, but have yet to receive any. APS bills are through the roof and Sunrun is continuing to bill although the system is producing no electricity.  The best outcome would be to have them remove their non-functioning installation from my house, repair the roof,  and refund payments for the months when no power was generated. The frustration of dealing with this company is literally making us sick.  I am sufficiently frustrated that I am filing a consumer complaint with the Arizona Attorney General's office. Appalling business ethics as well as non-existent customer service.

Run from this company, they will lie, cheat and steal your money, that's what they're great at nothing else. Run Run Run and fast from them for your mental well being !!
