How does National City's climate affect this service?
National City solar cleaning splits between aging residential single-family arrays in the older Craftsman blocks and Filipino-American family neighborhoods, and commercial rooftop arrays along the Mile of Cars and I-805 corridor. Mild coastal influence keeps soiling moderate but traffic film from I-5 and I-805 is a steady factor.. We account for local conditions in every job.
Can you clean while we keep the array online?
Yes. Cleaning is performed with the system live in most cases. We use insulated tools and deionized water (which is a poor conductor when pure). For arrays over 600 V DC or any utility-scale site, we coordinate with your O&M for safe shutdown.
Do you provide insurance certificates?
The solar-cleaning pros we match are insured and carry general liability and workers' comp. Ask them for a current certificate of insurance before they start.
