Your solar panels work hard in Temecula’s 275+ sunny days each year, but dust, pollen, and bird droppings can steal up to 25% of their efficiency. Clean panels don’t just look better—they produce significantly more electricity, which means lower energy bills and faster payback on your investment.
Professional cleaning restores your panels to peak performance. You’ll see the difference immediately in your energy production monitoring app, and you’ll feel it in reduced monthly electricity costs. Most Temecula homeowners notice their panels producing 10-25% more energy after a thorough cleaning.
The math is simple: cleaner panels equal more power, more savings, and better protection of your valuable solar investment.

Our solar panel cleaning service includes thorough cleaning of all accessible panels, inspection for damage or wear, and removal of all debris including stubborn bird droppings that rain can’t wash away.
In Temecula’s climate, we typically recommend cleaning every six months—spring and fall work best. Properties near vineyards, construction sites, or with heavy bird activity may benefit from quarterly cleaning to maintain peak efficiency.
We serve all of Temecula and surrounding areas, working with both residential and commercial solar installations. Every job includes our satisfaction guarantee because we want your panels producing maximum energy for years to come. Our eco-friendly approach protects both your investment and the environment.
In Temecula’s climate, solar panels should be cleaned at least twice a year—typically in spring and fall. This schedule removes accumulated dust from dry summers and debris from occasional winter storms.
However, your specific location may require more frequent cleaning. If you live near vineyards, agricultural areas, or have many trees around your property, quarterly cleaning may be beneficial. Properties with heavy bird activity also need more frequent attention since bird droppings can block sunlight completely and won’t wash away with rain.
The best indicator is your energy production monitoring. If you notice a drop in output, it’s time for cleaning. Most Temecula homeowners find that staying on a regular schedule prevents major efficiency losses and keeps their systems producing optimal power year-round.
Yes, studies consistently show that dirty solar panels can lose 15-25% of their efficiency, with some cases reaching even higher losses. In Temecula’s dusty environment, this efficiency loss can happen faster than in other climates.
The problem compounds over time. A thin layer of dust might only reduce efficiency by 5%, but as pollen, bird droppings, and debris accumulate, the losses become significant. Bird droppings are particularly problematic because they create complete shadows over cells, blocking all sunlight in those areas.
Professional cleaning typically restores 10-25% of lost efficiency immediately. For a typical residential system, this translates to hundreds of dollars in additional energy production annually. The investment in regular cleaning pays for itself through increased power generation and extended panel life.
We strongly recommend professional cleaning for rooftop solar installations. Climbing on roofs is dangerous, and working with water near electrical equipment requires proper training and safety equipment.
DIY cleaning also risks damage to your panels. Using wrong tools, harsh chemicals, or tap water can scratch panels, leave mineral deposits, or even void manufacturer warranties. Many panel manufacturers specifically require professional cleaning methods to maintain warranty coverage.
Ground-mounted systems can sometimes be safely cleaned by homeowners using a garden hose and soft brush, but even then, using the right water and techniques is crucial. Professional cleaners use pure water systems and specialized tools that ensure optimal results without risk to you or your equipment.
We use manufacturer-approved cleaning methods with vehicle-mounted pure water purification systems. This removes all minerals and impurities from water, preventing spots and residue that can reduce panel efficiency.
Our specialized brushes are designed specifically for photovoltaic surfaces—soft enough to prevent scratching but effective at removing stubborn debris. We never use harsh chemicals, high-pressure washing, or abrasive materials that could damage panels or void warranties.
The pure water method is recommended by major solar manufacturers because it leaves panels completely spot-free without chemical residue. This approach is both effective and environmentally friendly, ensuring your panels stay clean longer while protecting your investment and the environment.
Solar panel cleaning costs vary based on system size, accessibility, and specific cleaning needs. Most residential systems in Temecula range from reasonable service fees that quickly pay for themselves through increased energy production.
The key is viewing cleaning as an investment, not an expense. If dirty panels are reducing your efficiency by 20%, professional cleaning that restores full performance typically pays for itself within months through increased energy savings.
We provide free estimates and transparent pricing with no hidden fees. During our assessment, we’ll evaluate your specific system and provide exact pricing along with recommendations for optimal cleaning frequency based on your property’s unique conditions and energy production goals.
Professional cleaning using manufacturer-approved methods will not void your warranty—in fact, many warranties require proper maintenance to remain valid. We use only recommended cleaning techniques and pure water systems that meet manufacturer specifications.
DIY cleaning with improper methods, harsh chemicals, or abrasive tools can void warranties. Some manufacturers specifically prohibit certain cleaning products or high-pressure washing. Our professional approach ensures compliance with all manufacturer requirements.
We’re fully insured and trained in proper solar panel maintenance procedures. Our methods are designed to clean effectively while protecting your warranty coverage and extending panel life. We can provide documentation of our cleaning methods if needed for warranty purposes.
