What are your procedures for ensuring a contactless installation process?

Solar is installed on the roof or on the ground, and we already observed social distancing procedures. Our crews wear safety equipment including Personal Protection Equipment to prevent the spread of COVID 19 not only to our clients, but also within our crews.

How is the sales process if we cannot meet in person?

With just a few pieces of information about your solar project, we can design an online solar proposal for your review. We then set a time to review the proposal by phone or Zoom to answer any questions you have. The financing process is paperless and contactless, any hard copies are sent by Priority Mail/FedEx. All of the contracts and disclosures are contactless using e-signatures.

How is the permit process contactless?

Many jurisdictions are starting to allow online permit applications and communication is facilitated by email. Final inspections are still completed in person, but social distancing and PPE is used to prevent the spread of COVID-19.

How do we ensure our installation crews are COVID-19 free?

Any of our installers that show up to work with an elevated temperature, coughing, fever or other sickness, they are sent home until the symptoms have subsided.

Where can I find more information about COVID-19 and the Solar Industry?

Please check with the SEIA (Solar Energy Industry Association) on all of the latest developments and safety protocols in the solar industry.
