Solar panels are one of the smartest investments a Texas homeowner can make — but without the right care and attention, even the best systems can underperform.
While solar energy is low-maintenance, it’s not “no-maintenance.” Many homeowners unknowingly make small mistakes that shorten their system’s lifespan or reduce efficiency.
Here are the most common solar panel mistakes to avoid — and how to protect your investment for decades of reliable, clean energy.
1. Skipping Regular Cleaning
Texas dust, pollen, and rain residue can create a thin layer of grime on your panels. Over time, this buildup blocks sunlight and reduces output by as much as 20%.
Avoid it: Schedule professional solar cleaning at least twice a year. It’s the simplest way to boost energy production and maintain efficiency.
2. Ignoring Annual Maintenance
Many homeowners assume that if their panels are producing power, everything is fine. But small wiring issues, loose mounts, or inverter problems often go unnoticed until they cause major drops in performance.
Avoid it: Get a professional maintenance inspection every year to test electrical connections, mounts, and system health.
3. Using Unlicensed Contractors for Repairs
Electrical work on solar systems must follow strict Texas code. Hiring unlicensed or inexperienced contractors can cause safety hazards, void warranties, or even damage your roof.
Avoid it: Always choose licensed solar electricians who specialize in code-compliant repairs and maintenance.
4. Forgetting About Roof Condition
Your solar panels depend on a strong, watertight roof. Installing panels on an aging or damaged roof can lead to leaks and costly removals later.
Avoid it: Inspect and repair your roof before solar installation. Coordinate with licensed professionals who can prepare your roof for solar.
5. Not Monitoring System Performance
Most systems come with a monitoring app that tracks energy production — but many homeowners rarely check it. If your system output drops, you might not notice for months.
Avoid it: Check your app weekly. If production dips suddenly, call for a diagnostic check. Early action prevents long-term energy loss.
6. Assuming Rain Cleans Panels
Rain may rinse off loose dirt, but it also leaves behind streaks, pollen, and minerals that build up over time. This residue lowers light absorption and overall output.
Avoid it: Schedule professional solar cleaning with purified water and non-abrasive tools to keep panels spotless.
7. Neglecting the Inverter
The inverter is the heart of your solar system. When it fails or runs inefficiently, your panels can’t convert sunlight into usable electricity.
Avoid it: Check inverter lights regularly — green means all clear; red or orange signals a problem. Call a professional if warning lights appear.
8. Overlooking Shading Issues
Even small amounts of shade from trees, chimneys, or debris can lower system output dramatically.
Avoid it: Trim trees and remove obstructions seasonally. Ensure nothing blocks sunlight throughout the day, especially during peak hours.
9. Failing to Schedule Inspections After Roof Work
If you replace or repair your roof, your panels will likely need to be detached and reset. Failing to have them professionally reinstalled can cause leaks or wiring issues.
Avoid it: Always schedule a solar inspection after roofing work to verify safety and proper reinstallation.
10. Not Updating System Components
Technology evolves. Over time, newer inverters, monitoring systems, and panel models can increase efficiency. Sticking with outdated components may limit your system’s performance.
Avoid it: Ask your solar provider about upgrade options during maintenance visits to keep your system up to date.
