Solar SLD Template: What a Good One Includes

Published: June 4, 2026 · By Kaelan Taeni

Searching for a solar SLD template is a common starting point for installers who want to speed up their compliance paperwork. A template can help, but it has real limitations. Here is what a good solar SLD template includes, and a faster, more reliable alternative.

What is a solar SLD template?

A solar SLD template is a pre-drawn single line diagram, usually for a typical residential system, that you adapt for each job. The idea is to avoid drawing from scratch every time by editing a standard layout instead.

What a good template should include

  • The PV array with space to show strings and modules per string.
  • Inverter and its MPPT inputs.
  • DC and AC isolation and protection.
  • Metering and grid connection point.
  • Clear standard symbols and labelling aligned with AS/NZS 5033.

The problem with static templates

A fixed template works until a job is not standard, and many are not. Multi-inverter systems, mixed string lengths, added batteries or unusual protection all mean editing the template by hand, which is slow and error-prone. The bigger risk is the diagram drifting out of sync with the actual design, exactly the kind of mistake that undermines a compliance document.

A faster, more reliable alternative

Rather than maintaining and editing a static template, you can generate the SLD directly from your system design. Solar Proof's browser-based SLD editor auto-populates the diagram from your panel, inverter and string configuration, so it always matches the job, then lets you adjust and export a print-ready PDF. It is the speed benefit of a template without the risk of it being out of date.

The bottom line

A solar SLD template can save time on standard residential jobs, as long as it includes the array, inverter, isolation, metering and correct labelling. For anything non-standard, generating the SLD from your design is faster and far less error-prone. Learn the basics in how to draw a solar SLD.
