Sun Services USA Services and Installation

Sun Services provides just the basics when it comes to services, including solar panel installation and solar monitoring, so customers looking for more customization options might need to turn elsewhere. The installation process is relatively smooth, although some customers have complained about delays along the way.

Solar Installation Experience

The installation process is similar among most solar installers, with some minor differences. Below is a breakdown of what you can expect when hiring Sun Services to complete your solar panel installation.

Step 1: Fill Out the Company’s Contact Form

Your first step is to provide Sun Services with some basic contact and property information via the contact form on its website (there is a separate choice if you’d like a quote for a new roof). A project management representative will connect with you shortly thereafter to confirm the details and get some additional information.

You should be prepared to discuss the appliances and electronics in your home, your average monthly energy consumption (which can be found on your past electric bills), shading on your roof from trees and buildings, your HVAC (heating, cooling and ventilation systems) and more. The rep will then explain the entire process of installing solar and walk you through the next steps.

Step 2: Design and Approval Phase

A solar panel system designer from Sun Services will then get to work to design the system that suits your home best. This tech will connect with you to approve the design, discuss solar needs and expectations, estimate your savings and more. The phone call or video chat should last twenty minutes to a half-hour.

Step 3: Permitting and Installation

Once you approve the final design, Sun Services will begin pulling permits required for the work. As soon as permits are approved, your representative will connect with you to schedule an installation date, and the installation team and electricians will install your system according to the plan and specifications.

Step 4: Commissioning Your System

The final step of the process will be commissioning (turning on) your system. Once the solar panels are producing energy, you can begin saving money on your electric bills!

Sun Services USA Customer Service

Generally speaking, Sun Services maintains a great reputation for customer service. Most customers are pleased with the communication, honesty and transparency the company provides, although there are some negative customer reviews stating that communication was lacking throughout the process.

Post-installation customer service seems to have the same reputation, with most customers satisfied but some claiming warranties are hard to take advantage of if there are issues.

Sun Services USA Costs and Financing

The price of solar panels in Arizona will always be high, but Sun Services is a great option for keeping costs down. The overall price of photovoltaic equipment from this company is around average, and the quality of service and the products provided for that price are excellent.

The average cost of solar panels in AZ is around $3.01 per watt, although prices can vary based on the equipment you choose and the size of the system you need. Most Arizona residents will find their system totaling between $18,963 and $31,605 after the federal solar investment tax credit (ITC) is considered. Sun Services typically falls around the average based on solar system size.

Financing Options Through Sun Services USA

Sun Services accepts cash purchases and solar financing options through Dividend, Mosaic and Sunlight Financial, but it doesn’t accept solar leases or power purchase agreements (PPAs). Most customers will be able to find a solar loan that works for them and fits within their budget. You can find some basic information on the different solar purchase and financing options below.

Positive Sun Services USA Reviews

Below are some of the positive reviews that capture the general consensus reached by countless other reviews.

“Great price and outstanding value. Communication was great and the project was executed ahead of schedule. I couldn’t be more satisfied. Matt Nam (the sales rep) was very thorough and did a great job articulating our options. Excellent communication, coordination, and follow-up after the sale. It is definitely worth giving this company a look if you are in the market.” — Jeff via Google Reviews

“I had a solar system installed on my home in Prescott, AZ. We had 21 panels installed and couldn’t be happier. Team 3 did a great job with the installation. They were respectful and clean. The AZ Sun Services staff was very informative and kept me up to date as things changed and progressed. From the start we were happy with the services that were provided. I’d like to add that if you need a roof, they can help you with that as well.” — Anthony via Google Reviews

Negative Sun Services USA Reviews

As is the case with any company, there are some negative reviews of Sun Services online. Most of them concern slow installation timelines, and a few state that there are issues with communication between Sun Services and the panel manufacturers, leading to slow fixes.

“Seven months since I signed the contract. It took them four months to get the permits. Month five they finally installed the breaker panel on the second try after a no-show/no-call. Tore up the stucco and concrete and have not fixed it yet. […] Took them eight months to finally install my system (took them two days), but now the Cellular Monitoring keeps losing connection. […] Talk about poor customer service.” — Mike via Google Reviews

“The service is excellent, however they do not have a clue how to make my system work. Tech has over 40 hours of troubleshooting and is getting no support from the manufacture[r]. At this point it is still not working five months after the initial install. They came out again today [and] installed what the manufacturer said was the fix. Guess what it’s not working. Great service and no support does not work.” — Alex via Google Reviews
