Frequently Asked Questions

Q: How often should solar panels be cleaned on Cape Cod?

A: Due to salt air, coastal moisture, pollen, sand, and bird activity, most Cape Cod solar systems should be professionally cleaned every 6–12 months. Waterfront properties and high-pollen areas often require cleaning every 3–6 months to maintain peak efficiency.

Q: Does cleaning solar panels really improve energy production?

A: Yes. Dirty solar panels can lose 15%–35% or more of their energy output when coated with salt film, pollen, or debris. Professional cleaning restores maximum sunlight absorption, helping your system produce the power it was designed to generate.

Q: Is it safe to clean solar panels yourself?

A: DIY solar panel cleaning is not recommended, especially on Cape Cod roofs. Walking on wet roofs is dangerous, and improper tools or detergents can scratch glass, damage coatings, void warranties, and reduce system lifespan. Professional cleaning ensures both safety and proper performance.

Q: Why is salt air so harmful to solar panels on Cape Cod?

A: Salt mist sticks to solar glass and frame edges, creating a corrosive film that traps moisture and blocks sunlight. Over time, this can lead to permanent staining, electrical degradation, and reduced panel lifespan without proper maintenance.

How soon can I get on the calendar?

After an estimate approval, jobs are typically scheduled anywhere from 2-4 weeks out - depending on the season. We do our best to try and accomodate homeowners that are feeling the pressure from insurance companies giving them a 30 day notice. We recommend homeowners to call us for an estimate in early March if they want their homes clean and ready for Spring. 

Q: How much does solar panel cleaning cost on Cape Cod?

A: Solar panel cleaning costs vary based on panel count, roof pitch, access, and frequency. Wash Safe provides free, transparent estimates with no hidden fees and offers maintenance plans for long-term savings.
