Simplifying Solar PV System Design for Contractors & Engineers

Simplifying Solar PV System Design for Contractors & Engineers ☀️

Designing a solar PV system isn’t just about placing panels — it’s about precision, performance, and profitability.

For contractors and engineering teams, the real challenge lies in balancing technical accuracy with fast project turnaround. That’s where structured calculations and smart digital tools make the difference.

I help teams transform complex solar design calculations into streamlined, client-ready system layouts using automated Excel models and interactive dashboards.

🔎 Core Solar PV Design Calculations

1️⃣ Solar PV Array Sizing

• Daily Energy Demand (Wh) = Total Connected Load × Operating Hours

• Required PV Capacity (W) = Daily Energy ÷ (Peak Sun Hours × System Efficiency)

• Number of Panels = Required PV Capacity ÷ Panel Wattage

2️⃣ Battery Bank Design

• Battery Capacity (Ah) = Daily Energy ÷ (Battery Voltage × Depth of Discharge × System Efficiency)**

3️⃣ Inverter & BOS Sizing

• Inverter Rating = Peak Load × Safety Factor

• Charge Controller Rating = Total Array Current × Safety Margin
