Key Components of a Suntech Kit
Typical kits contain:
- Solar panels (usually 250‑350 W each)
- Mounting racking system (rails, clamps, and brackets)
- String inverters or micro‑inverters
- Power cables, combiner boxes, and junction boxes
- Grounding equipment and safety disconnects
Installation Steps
Site Assessment
Check roof orientation, shading, and structural load capacity. Suntech panels perform best on south‑facing roofs with minimal shade.
Mounting the Racks
Secure the racking system to the roof or ground according to the manufacturer's torque specifications.
Wiring the Panels
Connect panels in series or parallel, then link to the inverter. Follow NEC or local code requirements for grounding.
Inverter Installation
Mount the inverter close to the electrical panel. Connect it to the combiner box and then to the main service panel.
Inspection and Testing
After installation, perform a safety inspection and run a performance test to verify voltage, current, and power output.
Cost Breakdown
Prices vary by kit size and region. A typical 5‑kW Suntech kit (15 panels) averages $6,000–$8,000 before tax credits.
| Component | Estimated Cost | Notes |
|---|---|---|
| Solar Panels (15) | $3,000 | $200 each |
| Mounting Hardware | $500 | Depends on roof type |
