    Wow! My solar is producing approx. 50% better after having my cleaning service. They were on time and highly communicative. They were efficient and extremely professional. They even took the time to educate me on what all the different numbers meant on my solar panel. 10/10 I would recommend this company to any one looking to have solar cleaning done. Thank you guys!

    I recently hired Postmil Solar Cleaning to clean my solar panels, and I couldn’t be happier with their service! From start to finish, the experience was professional and seamless. The team arrived on time, equipped with specialized tools and eco-friendly cleaning solutions that left my panels spotless without any risk of damage. The technicians were knowledgeable, explaining how regular cleaning can boost panel efficiency and answering all my questions about maintenance. They also took care to protect my roof and surrounding areas, leaving no mess behind. Pricing was transparent and competitiv

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

Its website also mentions warranty, but not in a sentence we can quote cleanly.

  • It posts on Instagram. A page that stopped posting years ago tells you something a listing will not.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

What we don't know

  • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
  • Google publishes no street address for this company, so we cannot say which town it is based in. Yucaipa is the area its listing was returned for, not an address we hold.
  • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
  • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
