Why a code and not just a link
Signature Solar's referral link on its own doesn't take anything off your order. The code is what gets you the discount, and it changes now and then, which is why this page exists: one address that always shows the current one. Bookmark it, or come back through the app.
If checkout rejects the code, it was just changed and this page is catching up — check back tomorrow. I earn a commission on orders placed through my link. Using it never raises your price; the code only lowers it.
