Sun City Solar Warranty

Sun City Solar Warranty-Five Years-Best in the Industry

When considering a solar power system, Sun City Solar Energy’s number one concern is the performance and aesthetics of your system.

Separate Components

Critical to understanding the warranty on your solar power system is realizing that a solar power system is made up of separate components, each of which carries its own separate manufacturer warranty terms. The typical residential solar system consists of (1) the solar panels, (2) the batteries (Off Grid or Emergency Battery Backup)  (3) the power inverters and (4) the mounting system.

Solar Panels

Solar Panel cells are placed in and protected by a tempered glass case which is framed by non-corrosive aluminum. Because solar panels are exposed to the elements they are typically very sturdy and built to withstand rain, hail and other weather-related threats. In addition, the photovoltaic cells that make up the panel have very little break down over time, similar to computer chips. Sun City Solar chooses solar panels that are rated to withstand 1” size hail.

Sun City Solar Energy also selects only solar manufactures that offer a full warranty of their solar panels for 25 -30 years. Solar panel warranties are tied to power output. The warranties guarantee that the panels will operate at a minimum of 80% of their original peak power output in 25-30 years.  In addition, we select manufacturers that have a separate guarantee at 90% of peak power output, typically 10 years. “Peak power” is usually defined as the solar panels operating under certain optimum conditions.

In addition to the output warranty, Sun City Solars’ manufacturers will offer a limited warranty for “materials and workmanship.” The typical warranty under these circumstances is usually 5 years and basically protects consumers against defectively manufactured panels.


Battery based solar systems come with batteries installed to store the electricity produced by the solar panel system. The good news is that solar power batteries do not have moving parts and absent a manufacturing defect, they is very little to go wrong with solar system battery. Most manufacturing warranties on the batteries we choose are between 5 and 10 years despite the fact that their useful life can be as much as 15 -20 years.

Power Inverters

Power inverters in solar systems can be one of the most expensive parts of your home solar power system. Inverters convert the electricity produced by the solar panels into electricity that is usable in your home. Power inverters are either mounted outside your home near your electric meter (string inverters) or under your panels (micro-inverters).  As a result of this, the power inverter is the most likely component of a home solar power system to fail.

When considering a residential solar system, make sure you do not skimp on a power inverter as it can save you money down the line by avoiding replacements. As a result, cheaper power inverters will have manufacturer warranties that are short, around 2 years. Sun City Solar uses only top brand inverters which have warranties up to 10-15 years. In fact, our most common install, Enphase Energy micro-inverters, are top of the line and come standard with a 25-year manufacturer warranty.

Mounting Systems

Mounting Systems come in a variety of options. Sun City Solar uses only metal structures for long lasting, high wind durability.  Mounting systems are typically rated to 120 MPH.  Unirac, IronRidge, DPW and AET are just a few of the mounting systems  we install. All are certified and rated for wind and weather.

Solar Installer Workmanship Warranty

In addition to the manufacturer warranties that make up the component parts of your home solar power system, you will also receive a parts and labor warranty from Sun City Solar Energy.  Sun City Solar Energy, a premier solar installer, offers a workmanship warranty of five years.
