Open market. Your data.

How SDL works with installers and engineers

SDL is a design tool. We sell it to solar professionals across the market: installers and engineers alike. Installers can design their own plansets in SDL; engineers can use it for their own projects and stamp work. That’s the product, and it’s the same product for everyone.

What this means for competition

Because installers can design their own plansets here, SDL is a tool that lets installers do work that engineering firms have traditionally done for them. We also market SDL to installers across the market, including installers who may already work with engineers who use SDL. An installer’s right to use our tool isn’t limited by who else they work with.

If you’re an engineer using SDL, you should expect that installers in the market, including ones you work with, may be SDL customers too. That’s the nature of an open tool, and signing up means understanding it.

What we will never do

We will not use your account data to compete with you. The installers, project details, volumes, and client information visible to us because you use SDL are off-limits as a source of sales targeting. We compete in the open market like anyone else, through marketing, referrals, and inbound interest, never by mining what we can see inside your workspace.

Your clients are yours. The open market is everyone’s. Your data is not our advantage.

One policy, everyone

This applies to every account on the same terms. Whether you signed up today or moved over from an earlier version of our tools, you’re a customer under this same policy, with the same promise and the same expectations. No special cases, no quiet exceptions.
