Solar panels are a fantastic way to save money on energy while reducing your carbon footprint, but maintaining their efficiency over time is essential for maximizing your investment. For Rhode Islanders, the region’s unique weather and environment require a few extra considerations. Here are five things to remember to keep your solar panels running efficiently year after year.
1. Keep Your Panels Clean
Rhode Island’s coastal winds can carry salt, dirt, and debris, while seasonal pollen and bird droppings can build up on your panels, blocking sunlight and reducing efficiency.
How to Clean: Use a soft brush or a garden hose with clean water to gently remove grime. Avoid abrasive materials or harsh chemicals that could damage the panels.
When to Clean: Clean your panels every 6-12 months, or more frequently if you live near trees, experience heavy bird activity, or notice a drop in energy production.
Pro Tip: Coastal areas might require more frequent cleaning due to salt buildup from the ocean air.
2. Monitor Your System’s Performance
Regularly monitoring your solar system ensures it’s operating at peak efficiency and helps identify issues early.
Use Solar Monitoring Tools: Most solar installations come with a monitoring app or dashboard that tracks your system’s energy production.
Watch for Trends: A sudden drop in production, not related to weather, could indicate a problem such as shading, dirt buildup, or a malfunction.
Pro Tip: Compare your system’s current performance with the same period in previous years to spot anomalies and ensure consistency.
3. Trim Nearby Trees to Prevent Shading
Shading from trees is one of the biggest culprits in reduced solar panel efficiency. Over time, growing branches or new trees can cast shadows that block sunlight.
Prune Regularly: Trim back overhanging branches and ensure trees around your property don’t interfere with panel exposure.
Other Shading Sources: Keep an eye out for new construction or objects like chimneys and satellite dishes that may cause shading as the seasons change.
Pro Tip: Rhode Island’s dense greenery means regular tree trimming is especially important to prevent gradual shading over time.
4. Schedule Regular Inspections
Routine professional inspections can ensure that your panels and system components are in top shape.
Inspect for Damage: Rhode Island winters can be harsh, with snow, ice, and high winds potentially causing cracks, corrosion, or loose connections.
Evaluate the Whole System: Ensure inverters, wiring, and mounting systems are all in good condition and operating correctly.
Pro Tip: Schedule inspections every 1-2 years, and always after severe weather events like hailstorms or hurricanes.
5. Manage Snow and Ice Buildup in Winter
Rhode Island winters bring snow and ice that can temporarily block sunlight and reduce solar panel efficiency. While snow often slides off panels naturally, prolonged buildup can be a problem.
Remove Snow Safely: Use a soft roof rake or a snow removal tool designed for solar panels to gently clear the snow. Avoid sharp tools that could scratch the surface.
Prevent Ice Buildup: Panels with the proper tilt will allow snow and ice to slide off more easily, but make sure they’re installed at the right angle.
Pro Tip: Don’t stress over a light dusting of snow—panels will resume production as soon as the sun comes out and melts it away.
Conclusion
Keeping your solar panels efficient in Rhode Island requires a mix of proactive care and regular monitoring. Clean your panels, track their performance, trim nearby trees, schedule inspections, and manage snow and ice buildup to ensure your system continues to produce energy at peak levels. By following these five tips, you can enjoy the full benefits of your solar investment for years to come—no matter what New England weather throws your way!
