Design That Fits Your Workflow
Lyra is a fast and powerful residential PV solar design tool and permit package generation platform.
Create and export permit-ready design plans of any complexity.
How it Works
Create a code-compliant design in a few quick steps
Trace individual roof faces or import a full roof plan and then design a system that is compliant with adopted electrical, fire, and other codes. Create a concept design that is permit-ready in just a few minutes.
Highlights
Create a PV system design for an on-demand permit package
With Lyra, you can choose the degree of detail that works best for you workflow and meets your client's needs–from layout-only to complete permit-ready designs.
Flexible Site Definition
Define individual roof faces or complete roof plans
Quick and Flexible PV Concept System Design
Create a design in as little as a few minutes
Generate a default layout that’s optimized to maximize coverage, then easily customize it as much as you want. Individual modules can be repositioned and rotated for highly customized mixed portrait/landscape layouts. The tool generates fire code-compliant ventilation setbacks and fire access pathways that can also be modified with ease.
Design the layout you want
Generate a default layout that’s optimized to maximize coverage, then easily customize it as much as you want. Individual modules can be repositioned and rotated for highly customized mixed portrait/landscape layouts. The tool generates fire code-compliant ventilation setbacks and fire access pathways that can also be modified with ease.
Comply with fire codes
Lyra generates fire-code compliant ventilation setbacks and fire access pathways that can also be modified with ease. The intelligent design creation is based on the adopted fire code, roof edge types, PV module placement, and the location of the nearest street and driveway.
Create electrically-valid module strings
Our intuitive yet powerful interface makes your life easy by supporting conventional string inverters, microinverters, and inverters that require optimizers. While stringing modules isn’t required for a minimally viable concept design, Lyra makes it quick and easy while ensuring that stringing conforms to adopted electrical codes and product manufacturer requirements.
Energy production estimates
We use the latest version of PV Watts to reliably model estimated energy production. Lyra allows you to fine tune system loss parameters.
Add an energy storage system
Add an energy storage system to the design. Just as with PV module strings, Lyra makes it easy while ensuring the PV + ESS configuration conforms to adopted electrical codes and product manufacturer requirements.

Design with confidence, knowing that Lyra stays up to date on the latest building codes
Upgrading a concept design to a permit-ready design is a quick two-step process. It’s simple to add racking hardware, disconnects, combiners, transition boxes, OCPDs, conduit, and conductors. Lyra will ensure the design complies with the applicable electrical codes.
