"long store but please read if you have a tesla charger install by them or electrical work. had a tesla charger installed by them last year 2019 few months after the install the charger stop working i use the tesla model X on the weekends only and charger 1-2 times a month so probably use it less than 15-18 times when the charger stopped working i gave Aztec solar a call and one of the installer came by a week later to fix the issue. and the issue was the breaker caught on fire and burnt that was very dangerous and its a large 80 amp breaker luckily my house didn't burn down any ways their tech replace the breaker and assure me this will not happen again he also made some adjustment to the tesla charger saying the charger is the cause (which is strange because if the charger was the issue by over charger or some thing it will trip the breaker but not cause it to burnt but he knows more than me so i didn't' question him just happy it was fixed) and last month the charger stopped working again i remember the first time the same thing happened so i went to the main panel and check the breaker the breaker is still in the ON position and i can small a bit of burn plastic so i turn it to off then back to on position and i can hear arcing sound from the breaker i immediate put it to the off position again and left it there i gave Aztec solar a call told them the charger stopped working and have the same issue as last time and few days later they called me back and told me the warranty has passed and the service call is 130 dollars plus 70 dollars a hour and gas fee plus part cost. i told them the same issue they try to fix last time was not done properly and the breaker they installed has caught on fire again. they said we still have to charge you even if the problem was not fixed properly last time when the install was still in warranty. if you value your house and don't want to put your family at risk do not use these guys i had another electrician come by and he open the panel and below are the picture of the burnt breaker again the issue was the clamp on the breaker they installed is too far apart and not making good connection on the main panel so it's like a welder getting hot every time i charge and finally just caught on fire luckily this time it didn't burn down my house just have to replace this breaker with the correct one and replace the surrounding breaker that was burn by this one."

With many years of experience, our goal at RCI Solar, Inc., is to offer each and every customer the best possible service and quality available. We look forward to working with you soon on your next project and thank you for your interest.
"Needed 10 year old solar panels removed and reinstalled to accommodate a new roof job. Rick and his crew at RCI are INCREDIBLE! The bid was very fair (compared to the original installer who wanted to rip us off); the work was completed as promised and Rick even initiated a warranty claim for 2 micro inverters we didn't even know were not functional. Rick is probably the most professional, ethical, and knowledgeable business person we've dealt with in quite some time. RCI was referred by a roofer we ended up not using, yet RCI still came through for us! Rick's team even spent significant time to fix the bad wiring job from the original installer at no extra cost I am thankful we switched from our original installer to RCI. HIGHLY RECOMMEND!"

The average cost to install solar panels is around $26,600, and most homeowners pay between $4,500 and $53,000. Keep in mind that these prices don’t consider the federal investment tax credit (ITC), which can effectively reduce those costs by up to 30%. The price you can expect to pay for solar panel installation depends on the size of the system, where you live, the type and brand of panels, and the labor costs. Get price quotes from at least three solar companies in your area to find the best deal.
In most states, solar installers need to be licensed and insured as solar professionals, although some states don’t have specific requirements for installers. You can use our state licensing tool to check if an installer you’re considering hiring holds the proper licensing. No matter where you live, a member of your solar panel installation company must be a certified electrician to connect your panels to your home and the electric grid.
There are a few qualifying questions you should ask a local solar panel company before hiring them:
Will you handle permits for the installation?
Does your total price include the equipment and labor?
How long do you expect the installation process to take?
What kind of workmanship warranty do you include with your installations?
Who should I contact if I have a problem with my system after installation?
Do you install the panels or outsource the work to third parties?
Will you file for solar incentives for me?
In most cases, yes, solar panels are well worth the investment. Going solar with your home’s energy is expensive, but, in most states, the panels will pay for themselves by reducing your electric bills. Solar panels don’t produce greenhouse gasses or other pollutants, meaning you can feel good about using this renewable energy source to power your home. Plus, installing solar panels can boost your home value, helping your profit off your next home sale.
Yes, solar panel installation will require permits. The required permits will depend on where you live, as some states and cities have solar-specific permits, while others only require electrical permits to connect to the grid. In either case, it’s best to hire a reputable solar installer in your area, as a representative should handle all of the necessary permitting for you and will include the cost of the permits in your initial solar estimate.
