Few places in the country enjoy as much sunshine as Southern Utah. Clear skies and long summer days make it an excellent location for solar power, while hot weather drives up air conditioning use. A well designed solar system can reduce your energy bills, provide backup power and help you make the most of the region's greatest natural resource.
Why Solar Makes Sense Here
Solar panels produce the most energy on bright, clear days, and Southern Utah has plenty of them throughout the year. Summer is when air conditioners work hardest, and it is also when solar production is strongest. Even in winter, clear days provide useful production. Over a full year, a well designed system can cover a significant share of a typical home's electricity use.
Know Your Utility
How much you save with solar depends heavily on your utility's rules. St. George and several nearby communities are served by city owned utilities, while other parts of the state are served by a large investor owned utility. Each sets its own policies for connecting solar systems and crediting energy you send back to the grid. In recent years, many utilities have moved away from simple net metering toward export credit rates that value excess energy lower than the electricity you buy.
Before signing a contract, ask your installer to explain exactly how your utility will credit your system, what fees apply and how these rules affect your expected savings. A trustworthy installer will model your savings using your actual utility and rate plan.
Your utility can explain its current solar interconnection process, credit rates and any application requirements. It is worth confirming these details yourself before you commit.
Start With Your Energy Use
Gather a full year of electricity bills to understand how your use changes with the seasons. Many Southern Utah homes use much more electricity in summer because of air conditioning, pools and outdoor equipment. Knowing your pattern helps size a system that meets your needs without paying for capacity you do not use.
Before installing solar, consider simple efficiency upgrades. Sealing ducts, adding attic insulation, shading west facing windows and upgrading to an efficient heat pump can reduce energy use, allowing a smaller and less expensive solar system to cover more of your needs.
Batteries and Backup Power
When utilities credit exported energy at lower rates, storing solar energy for your own use becomes more valuable. A home battery stores excess energy produced during the day so you can use it in the evening, when air conditioners are still running and the sun has set. Batteries also provide backup power during outages, keeping essentials such as refrigerators, lights, fans and internet running.
Discuss with your installer which circuits you would want to keep running during an outage and how long you need backup to last. A battery designed around your priorities provides the best value.
Check Your Roof First
Intense sun and heat age roofing materials, so check your roof's condition before installing solar. If your roof is nearing the end of its life, replace it first to avoid removing and reinstalling panels later. Tile roofs, common in the area, require specialised mounting techniques, and some installers replace tiles under the panels with flashed mounts or other materials. Ask how the installer will protect your roof and how the work affects your roof warranty.
Heat, Dust and Performance
Solar panels lose a little efficiency as they get very hot, so good airflow beneath the panels helps. Dust and occasional dust storms can leave a film that reduces output. Rain often cleans panels naturally, but during long dry spells, gentle cleaning with water and a soft brush can restore performance. Never walk on panels, and consider a professional cleaning service for roofs that are difficult to reach.
Choosing Equipment
Ask about the brands, efficiency and warranties of the panels, inverters and batteries being proposed. Microinverters or optimisers allow each panel to work independently, which helps if part of the roof is shaded or faces different directions. Make sure the system meets current electrical and fire codes, including rapid shutdown requirements.
Buying, Financing or Leasing
Paying cash usually provides the best long term value. Solar loans allow you to spread the cost while still owning the system. Leases and power purchase agreements reduce upfront costs, but you do not own the equipment, which can complicate selling your home. Federal and state incentives for home solar have changed in recent years, so ask which programmes are currently available and how they apply to each option.
Be cautious of door to door sales pitches that promise free solar or rush you to sign. Take time to compare proposals and read every contract carefully.
Permits and Interconnection
Solar installation requires building and electrical permits, an inspection and approval from your utility before the system can be switched on. Homeowners associations may also have design guidelines. An experienced installer manages this paperwork and keeps you informed at every step.
Planning for the Future
Think about how your energy use may change in the coming years. An electric vehicle, a pool, a home office or a switch from gas appliances to electric can all increase electricity use. Design your system with room to expand, and make sure your electrical panel can support future additions. Planning ahead now can save the cost of upgrading equipment later.
Monitoring Your System
Most modern solar systems include an app or online dashboard that shows how much energy your panels produce and how much your home uses. Check it regularly, especially after storms or dusty periods. A sudden drop in production can signal dirty panels, a tripped breaker or an equipment fault that should be checked. Comparing production month to month also helps you understand how the seasons affect your system.
Solar and Your Home's Value
An owned solar system with a strong warranty can be an attractive feature for future buyers, particularly in a sunny region with high summer cooling costs. Keep records of your installation, permits, warranties and production history so you can share them when you sell. Leased systems require buyers to take over the agreement, so understand the transfer process before you sign.
