YOUR GARAGE IS COSTING YOU MONEY (EVEN WITH SOLAR!) 

At Solar Topps, we focus exclusively on premium solar installations, but we’ve helped thousands of Arizona homeowners understand how their entire home’s energy ecosystem affects their solar investment. Your garage plays a MUCH bigger role than you might think! 

WHY YOUR GARAGE TEMPERATURE MATTERS FOR SOLAR SAVINGS 

Your attached garage shares walls with your air-conditioned living spaces. When that garage heats up to extreme temperatures, it creates a massive heat transfer problem. How to keep the garage cool in summer According to Energy.gov, this heat transfer forces your cooling system to work harder and longer, significantly increasing energy consumption. 

Even with a top-quality solar system pumping out electricity, an overheated garage means you’re wasting precious solar power on unnecessary cooling. Our SolarTopps customers who implement garage cooling strategies typically see 15-20% better solar ROI in the first year alone! 

THE ARIZONA GARAGE COOLING SOLUTION GUIDE 

While SolarTopps specializes exclusively in solar installation (not insulation or HVAC), here are the proven methods our customers use to maximize their solar investment through smart garage temperature control: 

GARAGE RADIANT BARRIER INSTALLATION 

Radiant barriers installed in your garage attic space reflect heat rather than absorbing it, dramatically reducing temperatures. The U.S. Department of Energy reports that properly installed radiant barriers can reduce cooling costs by up to 10% in hot climates like Arizona. 

When combined with solar power, this means your system can cover more of your essential electricity needs instead of wasting production on excessive cooling demands. It’s a one-two punch for energy efficiency! 

MINI-SPLIT AC OR VENTILATION SYSTEMS 

Many of our SolarTopps customers choose to install dedicated cooling systems for their garages, from simple exhaust fans to mini-split air conditioners. Unlike traditional homes, solar-powered homes can run these systems virtually FREE during daylight hours! 

The National Renewable Energy Laboratory found that solar-powered mini-splits offer some of the highest efficiency ratings possible for cooling, with SEER ratings over 20, making them perfect companions to your solar system. 

GARAGE DOOR AND WALL INSULATION 

Simple insulation upgrades can have remarkable effects on garage temperatures. According to Energy Star, an insulated garage door can reduce the temperature transfer by up to 40° compared to non-insulated doors. 

Our SolarTopps customers report that combining insulated garage doors with solar installation creates a noticeable difference in their home’s overall comfort AND their monthly energy savings! 

SOLAR MAKES YOUR ENTIRE HOME COOLER (NOT JUST THE GARAGE!) 

Your SolarTopps solar system doesn’t just generate electricity – it helps cool your entire home in multiple ways: 

Solar panels absorb sunlight that would otherwise directly heat your roof surface. UC San Diego researchers found that solar installations can reduce roof temperatures by up to 38%, creating a natural cooling effect for the entire building. 

This passive cooling benefit reduces attic temperatures significantly, which in turn reduces the heat transfer to your living spaces. Your air conditioner works less, and your solar system covers more of your remaining energy needs! 

With a properly sized SolarTopps system, you’ll generate plenty of power to run garage cooling devices during peak heat hours. And with battery storage, you can even power these systems overnight using your own stored solar energy!
