Cleaning Solar Panels: Why It Matters and How We Do It
Professional solar panel cleaning service in Washington State. Improve efficiency, extend panel life, and keep your home eco-friendly.
Solar panels are an excellent investment for energy savings and sustainability, but to perform at their best, they need to be kept clean. In Washington’s climate, with frequent rain, pollen, and moss growth, panels quickly collect dust, grime, and organic buildup. Without regular solar panel cleaning, efficiency can drop by 20–30%, meaning you’re losing energy and money.
Why Cleaning Solar Panels Is Important
- Boosts efficiency: clear panels allow maximum sunlight absorption.
- Protects your investment: prevents buildup that can cause micro-scratches and long-term damage.
- Improves durability: regular care extends the lifespan of your solar system.
- Enhances appearance: clean panels add to your home’s curb appeal.
Our Solar Panel Cleaning Process
We use safe, professional techniques and equipment to deliver spotless results without harming your panels. Our process includes:
- Inspection of panels for dirt, moss, and bird droppings.
- Gentle washing with purified, de-ionized water to avoid streaks or mineral deposits.
- Soft brushes and non-abrasive tools to remove buildup without scratching glass.
- Final rinse and efficiency check for maximum sunlight absorption.
Unlike DIY cleaning, our method avoids harsh chemicals and high-pressure water that could void warranties or damage your panels.
How Often Should You Clean Solar Panels?
For most Washington homeowners, we recommend solar panel cleaning at least 1–2 times per year. If your property is surrounded by tall trees, near construction, or close to the coast, more frequent service may be needed. Seasonal cleaning before summer ensures your panels deliver peak performance during the sunniest months.
