QR codes for electricians, solar installers and service stickers
The next person to open the electrical panel, maybe the homeowner or another contractor, wants to know who worked on it and when. A service sticker with a code that opens your contact page and the job summary is useful for years.
For solar installers, the same code can open the system's monitoring page, warranty information and your support line.
This is a dynamic QR code: $3 once, and you can change where it points at any time without reprinting. How that works
What should a service sticker QR code open?
Information that stays valid and helps the next visitor.
- Your company name, phone number and how to book a repair.
- Date and type of the work, in general terms.
- Warranty terms and how to claim.
- A link to the manufacturer's manual or support page.
Are there safety rules about stickers on electrical equipment?
Yes, and they vary by region and by the product. A sticker must not cover labels, warnings or ratings, and it should not be placed where the manufacturer or local rules forbid it. Check the rules for your area and follow your own standards. We make the code, not the compliance decision.
How do I use QR codes for solar installations?
Put a code on the inverter or the meter box that opens the monitoring login and support page. Do not link to a customer's private account page from a public code. Link to your general support page and let the customer log in there.
Where else do electricians put QR codes?
On estimates and invoices (booking and reviews), on the van and on a leave-behind card that explains what to do after a power cut.
