Assessing Your Home's Suitability
Begin by measuring roof area, orientation, and shading. South‑facing roofs with minimal obstruction yield the best output. Use a solar path calculator or a simple 30‑minute sun chart to confirm peak sun hours.

Choosing the Right Panels and System Size
For a small house, a 3‑ to 5‑kW system typically covers 70–90% of average monthly consumption. Thin‑film panels offer lower cost but need more space; monocrystalline panels fit tighter roofs while maintaining higher efficiency.
Planning the Mounting Structure
Rooftop racking is the most common method. Secure brackets to the roof deck, ensuring they are rated for the local wind load. For flat roofs, use ballasted or pier‑mounted systems that avoid roof penetrations.
Electrical Connections and Inverter Placement
Connect panels in series or parallel to match the inverter's voltage rating. Place the inverter near the main service panel to reduce wiring losses. Follow NEC Article 690 for wiring, grounding, and overcurrent protection.
Permitting, Inspection, and Incentives
Contact your city or county for permits and utility interconnection agreements. Many municipalities offer rebates or expedited reviews for residential solar. Verify net metering policies to estimate potential savings.
Installation Steps
1. Secure the mounting system.2. Install racking and fix panels in place.3. Run DC wiring to the junction box.4. Connect inverter and feed into the electrical panel.5. Perform a safety inspection before energizing.
Maintenance and Monitoring
Clean panels quarterly in mild weather. Use a monitoring platform to track output and flag performance drops. A yearly inspection of mounting hardware and inverter health keeps the system reliable.
