Solar Panel Cleaning in Lithia & Tampa

At Radiant Clean, we’re proud to help Hillsborough County homeowners get the most from their solar energy investment. Serving Lithia, Brandon, Valrico, Riverview, Apollo Beach, FishHawk Ranch, and the greater Tampa Bay area, we use a pure-water, water-fed pole system that safely and effectively cleans solar panels without any harsh chemicals or high pressure. This gentle and eco-friendly method restores efficiency, protects your panels, and keeps your property looking its best—all while maintaining a smaller environmental footprint.


Why Solar Panels Need Regular Cleaning in Tampa Bay

Florida’s warm, humid climate and coastal air can take a toll on solar panels. Over time, layers of pollen, dust, tree sap, sea salt, and bird droppings accumulate on the glass surface. These contaminants block sunlight from reaching the photovoltaic cells, reducing efficiency and energy output. Even a thin film of grime can noticeably affect performance.


Regular cleaning is essential to restore lost energy production and maintain your manufacturer’s warranty. Many solar panel warranties require periodic maintenance to ensure panels operate within their designed efficiency range. Clean panels also help your solar monitoring system track performance accurately, so any production dips reflect real mechanical issues rather than a dirty surface. By keeping panels clean, you not only improve efficiency but also extend the lifespan of the glass, frames, and seals that protect your investment.


Solar panel cleaning using water fed pole

What Is a Water-Fed Pole System?

A water-fed pole system uses ultra-pure, deionized (DI) water pumped through a telescoping carbon-fiber pole to a soft, solar-safe brush. The pure water acts like a natural magnet for dirt and debris, lifting contaminants away from the surface without leaving any residue. Because the water contains no minerals or impurities, it dries completely spot-free, eliminating the need for soaps or chemicals.


The use of purified water is what sets this method apart. Tap water leaves behind minerals that can create water spots and streaks as it evaporates. Deionized water, on the other hand, removes everything except pure H₂O. As it rinses, it bonds with dirt particles and lifts them away. The result is a crystal-clear, streak-free finish that restores maximum solar efficiency. And because there are no chemicals or detergents, it’s safe for your landscaping, pool areas, and the environment.


Safety and Care: Protecting Your Panels and Property

Safety and care are at the core of Radiant Clean’s solar panel services. The water-fed pole allows technicians to clean panels from the ground or lower rooflines, significantly reducing the need to walk on the roof. This protects your roofing materials and prevents unnecessary wear on shingles or tiles. The soft-bristle brushes are specially designed for solar glass, ensuring coatings and seals remain intact.


Unlike traditional pressure washing, which can force water under seals or cause damage to anti-reflective coatings, our method uses gentle rinsing power. Every Radiant Clean technician is fully trained and insured, following manufacturer-approved cleaning guidelines for both safety and panel longevity. It’s a smart, non-invasive way to protect one of your home’s most valuable energy assets.

The Radiant Clean Process

Each service begins with a careful inspection of your solar array and surrounding environment. We assess roof pitch, debris sources such as overhanging trees, and access points for safe positioning. Next, we use pure, deionized water to loosen dust and pollen. Our solar-safe brush gently removes stubborn spots like bird droppings, and pollen before a final DI rinse leaves the glass spotless. Once the panels are clean, we perform a visual inspection and, if requested, provide before-and-after photos or help you verify production improvements on your solar monitoring app.


How Often Should You Clean Solar Panels in Tampa?

In Florida’s subtropical environment, most homeowners benefit from biannual cleaning, typically in the spring and fall. Homes closer to the coast, surrounded by trees, or near construction sites may need quarterly cleanings to maintain optimal output. Major pollen seasons, heavy storms, or periods of high humidity can leave behind stubborn residue, so scheduling after these events is ideal. Many customers in Lithia and the surrounding area find that maintaining a regular schedule ensures peak performance during the brightest and longest days of the year.


The Payoff: Real Energy and Cost Savings

Clean panels allow more sunlight to reach the cells, which translates into higher efficiency and better return on investment. Even a modest improvement of 5–10% can make a noticeable difference over time. For example, a 7-kilowatt system in Lithia produces about 11,500 kilowatt-hours annually. If regular cleaning restores 5% efficiency, that’s roughly 575 additional kilowatt-hours per year—equivalent to nearly $90 in savings at current Tampa Bay energy rates. Doubling that to 20% efficiency recovery can add up to nearly $368 a year in regained value. Over the lifespan of your solar system, those numbers compound into significant savings—all from simple, consistent maintenance.


Recurring Cleaning Plans: Save More and Stay Efficient Year-Round

To make solar panel maintenance effortless and affordable, Radiant Clean offers recurring service plans that ensure your system always operates at peak performance. Our biannual plan saves you $50 per visit, while our quarterly plan offers $100 in savings per visit. These discounted rates make it easy to keep your panels spotless without worrying about scheduling or seasonal buildup.

With each recurring plan, you’ll also enjoy priority booking during busy seasons and automatic reminders before your next service. It’s the most convenient way to protect your investment, keep your warranty valid, and ensure your panels continue producing clean energy efficiently all year long.
