Once your solar panels are installed, you might wonder: what comes next? Do they need regular maintenance? Should you be cleaning them? These are questions we hear often from homeowners across the country.
First things first: celebrate your smart investment in clean energy and the savings you'll see on your electricity bills! After installation, your system must pass a final inspection by local authorities to ensure everything meets safety codes. Your installer then handles the paperwork with your utility company to get Permission to Operate (PTO).
The timeline for PTO varies by utility and state—it can take anywhere from a few days to several weeks. Once approved, your system connects to the grid and you'll start seeing your solar production offset your energy usage on your monthly bills. The good news? Your installer typically manages this entire process for you.
Your utility company will adjust your billing to reflect your solar generation. Depending on your state's net metering policies, you may receive credits for excess energy you send back to the grid.
Do Solar Panels Require Technical Maintenance?
Generally, no. Solar panels have no moving parts, making them remarkably low-maintenance. When your system is installed, you'll get access to monitoring software that tracks your energy production in real-time.
If you notice a sudden drop in performance, contact your installer. They can diagnose whether there's a technical issue with the panels, inverter, or wiring. Most solar equipment comes with long-term warranties, so repairs or replacements may be covered.
How Do I Know If Something's Wrong With My Panels?
Most of the time, your solar panels work silently in the background. If there's a problem, you'll usually notice:
- A red light or error code on your inverter
- Unusual patterns in your monitoring app's production data
- Alert notifications from your monitoring system
According to the U.S. Department of Energy, checking these indicators regularly is the best way to catch problems early. If you do notice something unusual, reach out to your installer right away. They can often diagnose issues remotely and schedule service if needed.
Do I Need to Be Cleaning Solar Panels Regularly?
In most parts of the US, rain does the job of keeping panels clean. Solar panels are installed at an angle and have a special coating that helps dirt and debris wash away naturally.
For most homeowners, solar panel cleaning is minimal thanks to rainfall, but in dusty or coastal regions, you may need to schedule additional cleanings.
However, cleaning needs vary significantly by region:
- Desert Southwest: Dust and pollen can accumulate quickly. Consider checking panels every few months.
- Coastal areas: Salt spray may require occasional rinsing a few times per year.
- Northern states: Snow usually slides off panels naturally, though heavy accumulation might need gentle removal with a soft roof rake.
- Agricultural regions: During planting or harvest seasons, extra dust and pollen may warrant seasonal cleaning.
- Wildfire-prone areas: Ash and smoke residue may need attention after fire season.
- Urban and suburban areas: Generally require minimal cleaning thanks to regular rainfall.
If cleaning is needed, use a garden hose with plain water (ideally in early morning or evening when panels are cool). Never use pressure washers, harsh chemicals, or abrasive materials—these can damage the protective coating and void your warranty.
Some professional services are also beginning to offer specialized solutions for cleaning solar PV panels, especially for larger systems or hard-to-reach rooftops.
The Rise of Water Free Solar Panel Cleaning Robots
Water-free solar panel cleaning robots commonly searched for as ‘water free cleaning solar panel robots’ are being developed and tested in the US. While primarily used in large commercial installations today, this technology could become an option for residential systems as costs decrease—particularly valuable in drought-prone regions where water conservation is critical.
Some companies are even testing advanced options for cleaning solar PV panels, which could make maintenance easier for homeowners with larger systems or those in areas where water is scarce.
Should I Update My Homeowner's Insurance?
Roof-mounted solar panels are typically covered under standard homeowner's insurance policies as part of your home's structure. This usually includes protection against:
- Weather damage (hail, wind, storms)
- Fire
- Theft or vandalism
- Falling objects
Solar panels are built with tempered glass designed to withstand severe weather. We recommend:
- Notifying your insurance company about your installation
- Confirming coverage details and any policy adjustments needed
- Documenting your system with photos and keeping all paperwork
- Reviewing coverage limits to ensure they reflect your home's increased value
Most homeowners see little to no premium increase, and any small adjustment is typically offset by energy savings.
What About the Inverter?
Your inverter converts the DC electricity from your panels into AC power for your home. It turns on automatically at sunrise and shuts off at sunset. Since inverters generate heat during operation, installers place them in well-ventilated locations.
To maintain optimal performance:
- Keep the area around your inverter clear
- Don't cover it with boxes, coats, or other items
- Check occasionally that vents aren't blocked
- Be aware that inverters may need replacement during your solar panels' lifetime
Can I Change Electricity Providers After Installing Solar?
This depends entirely on where you live:
In regulated states (most of the US): You cannot choose your electricity provider—you remain with your utility company. Your savings come through net metering credits or other solar compensation programs your utility offers.
In deregulated states (such as Texas, Illinois, Pennsylvania, and parts of the Northeast): You can shop for electricity suppliers even with solar panels. When comparing providers, look at their solar buyback rates and how they handle net metering credits.
Federal and state solar incentives remain available regardless of your utility situation.
Maximizing Your Solar Investment
To get the most from your solar panels:
- Monitor regularly through your app to catch any issues early
- Shift energy-intensive tasks to daylight hours when possible
- Keep trees trimmed to prevent new shade on your panels
- Consider battery storage to increase energy independence (additional incentives may apply)
- Understand your utility's policies on net metering and time-of-use rates
Regional Considerations
Solar experiences vary across the country:
- Southwest states benefit from abundant sunshine but may need more frequent cleaning
- Northeast offers various state incentives and solar programs in many areas
- Southeast has growing solar adoption with improving incentive programs
- West Coast often leads in solar-friendly policies, though regulations continue to evolve
Your installer can provide specific guidance for your area's unique conditions and regulations.
