Preparation and Site Assessment
Begin by confirming that your roof can support the weight of Zamp panels and that it receives unobstructed sunlight for most of the day. Check local building codes and obtain any required permits; many jurisdictions require electrical inspections for solar installations. Measure the roof area, note pitch, and identify any shading from chimneys, trees, or adjacent structures, as these affect panel placement and output.

Gathering Tools and Materials
Typical kits include the Zamp panels, mounting rails, clamps, inverter, wiring, and grounding equipment. You will also need a drill with appropriate bits, torque wrench, multimeter, safety harness, ladder, and personal protective equipment such as gloves and eye protection. Having a detailed inventory before starting prevents delays.
Mounting the Rails
Secure the mounting rails to the roof according to the manufacturer's layout diagram. Use lag bolts or roof anchors that match the roof material—metal, shingle, or tile. Space the rails to match the panel dimensions, ensuring a level line across the array. Properly tightened fasteners reduce wind‑uplift risk and maintain panel alignment.
Typical Fastener Schedule
| Roof Type | Fastener | Spacing |
|---|---|---|
| Asphalt shingle | Stainless steel lag bolts | 24‑30 in |
| Metal standing seam | Self‑tapping screws | 20‑24 in |
| Tile | Tile‑specific anchors | 24‑30 in |
Check each anchor for a secure seal to prevent water intrusion.
Panel Installation
Lift each Zamp panel onto the rails using a suction lift or helper straps to avoid dropping. Align the panel's mounting holes with the rail clamps, then secure with the provided bolts. Keep a consistent gap—usually 2‑3 mm—between panels to allow for thermal expansion. Verify that the panel orientation matches the planned tilt and azimuth for maximum sun exposure.
Electrical Wiring and Inverter Connection
Run the DC wiring from the panel junction box to the inverter location, following local code requirements for conduit and wire gauge. Connect the positive and negative leads using MC4 connectors, ensuring polarity is correct; a reversed connection can damage the inverter. Install a DC disconnect switch within sight of the inverter for emergency shutdown. Once the inverter is mounted, link its AC output to your home's breaker panel, again respecting amperage limits and using a dedicated circuit.
Safety Checks
- Use a multimeter to confirm no voltage present before handling connectors.
- Ground the mounting framework and inverter according to NEC guidelines.
- Verify all connections are tight and free of corrosion.
Commissioning and Performance Verification
After wiring is complete, power up the system and monitor the inverter's startup sequence. Check that each panel reports expected voltage and current values; discrepancies may indicate shading, wiring errors, or defective modules. Register the system with Zamp's monitoring portal to track production over time and receive firmware updates.
Maintenance Tips
Inspect the array twice a year for loose bolts, debris buildup, or cracked seals. Clean the glass with a soft brush and mild soap solution—avoid abrasive materials that could scratch the anti‑reflective coating. Periodic thermal imaging can reveal hidden hotspots that affect efficiency.
