Retrofit Solar and Battery Site Plans, SLD’s and Structural Engineering
Solar Plans Canada now offers full structural engineering services tailored for residential retrofit solar building permit applications. This service includes the preparation of a Schedule-B letter, an insurance certificate, elevation drawings, solar attachment details, rail layout plans, and digitally stamped and sealed documents for online-only permit applications. Our detailed shop drawings, combined with elevation drawings, solar attachment, and rail layout, ensure precise fabrication and installation, meeting all structural and regulatory standards. These comprehensive services are designed to minimize delays and facilitate a smoother, more efficient approval process.
Key Features
Custom Site Plans
Detailed layouts specific to each project, ensuring safety and approval readiness
Single Line Diagrams (SLDs)
Essential for utility applications and permits, clearly depicting electrical pathways.

High Acceptance Rate
Minimize costs and stress with a high first-time acceptance rate and unlimited revisions at $50 each.
Prepare for Your Order
Please prepare your solar roof layout and gather the following documents for upload: product datasheets, architectural drawings, rough site plans, and draft single-line diagrams (which can be simplified).
For an efficient process, create a rough site plan that marks the electrical components: use a snapshot from Google Earth and indicate the locations of the Electricity Meter, Main Breaker Panel, any sub-panels, solar disconnects, inverters (if string), Batteries, and BMS (if
applicable). Include voltage and amperage details for each device, aiming for accuracy, especially for commercial projects.
You do not need to specify wire sizes; we handle those calculations. However, if necessary, mention wire sizes and the number of conductors (rather than conduit types like EMT & TECK90), as this simplifies Utility approval.
For City Building permit applications, ensure structural engineering is completed before placing your order. Attach your structural report, ensuring it complies with roof setbacks and includes a penetration diagram. We will incorporate this information into the drawings accordingly. Ground-mounted systems are also included in the below pricing.
