Why a PDF Guide Helps Your Solar Installation
A portable PDF consolidates all technical steps, safety checks, and local code references in one offline document, making it easy to share with electricians, inspectors, and homeowners. The format preserves diagrams and tables across devices, ensuring you follow the correct sequence from site survey to commissioning.

Preparing the Site
Start with a thorough assessment of roof orientation, shade analysis, and structural capacity. Use a solar pathfinder or a smartphone app to record sun hours, then verify that the roof can support the panel weight (typically 12–20 kg per panel). Document roof pitch, material, and any required reinforcements in the PDF's "Site Survey" section.
Choosing Mounting Hardware
Select rails, brackets, and fasteners that match your roof type—standing‑seam metal, shingle, or tile. The guide outlines the three most common mounting systems:
- Flush mounts for low‑profile installations.
- Tilted racks to optimize angle for latitude.
- Adjustable trackers for commercial arrays.
Include manufacturer part numbers and torque specifications in the table below.
| Mount Type | Ideal Roof | Typical Tilt (°) |
|---|---|---|
| Flush | Shingle, Tile | 0‑10 |
| Tilted Rack | Metal, Flat | 15‑30 |
| Tracker | Ground, Large Roof | Variable |
Electrical Wiring Basics
Run conduit from the array to the inverter, respecting local code distances (usually 1 m minimum from the roof edge). Use UV‑rated, 10 AWG cable for strings up to 600 V, and install a DC disconnect within sight of the panels. The PDF provides a wiring diagram that shows series‑parallel configurations, fuse ratings, and grounding methods.
Inverter Placement and Commissioning
Locate the inverter in a cool, ventilated area—preferably on the wall opposite the array to reduce DC cable length. Connect AC output to the main service panel via a dedicated circuit breaker, and program the inverter with the system's voltage, current, and expected production. The guide includes a checklist for final inspection, performance testing, and grid‑tie certification.
Safety and Maintenance Checklist
Before any work, shut off all DC circuits and wear insulated gloves and eye protection. After installation, verify that all fasteners are tightened to the specified torque and that the grounding system meets NEC or local equivalents. Schedule quarterly visual inspections and an annual cleaning routine to maintain efficiency.
