Solutions
Engineering-led solar design for every project
Every Firefly system is designed by licensed engineers. Precision engineering, APEGA-stamped drawings, and custom designs that maximize performance and ensure code compliance.
Technical Excellence
At a Glance
Firefly Solar's in-house engineering team designs every solar system from scratch — no generic templates. From structural analysis to electrical design to utility interconnection, our licensed engineers ensure your system is built right, approved fast, and produces optimally for decades.
APEGA-Stamped Design
Every system designed by licensed engineers and stamped by APEGA where required. Professional engineering ensures code compliance and permit approval.
Structural Analysis
Detailed load calculations for your roof or ground-mount structure. We verify your building can safely support a solar array before installation begins.
Electrical Engineering
Single-line diagrams, load calculations, and utility interconnection documentation. Everything your municipality and utility need for approval.
Custom System Design
3D modelling and shade analysis to maximize production. Every system is designed around your specific roof geometry, orientation, and energy goals.
Our Process
Engineering Process
A methodical, engineering-first approach to every solar project.
Understanding Your Property
We begin with satellite imagery, utility bill analysis, and a site visit to understand your roof geometry, structural capacity, electrical infrastructure, and shading conditions.
For commercial projects, we review architectural drawings and conduct detailed structural assessments. For residential, our advanced tools capture precise measurements remotely.
