Step 2 — System Design

System Type

🏠

Residential

1–10 kWp

🏢

Commercial

10–500 kWp

🏭

Industrial

500+ kWp

Usable rooftop area 3,000 m²

Exclude tanks, HVAC — typically 60–70% of total roof

Panel efficiency 20%

Mono-PERC: 19–22% · TOPCon: 21–24% · Budget poly: 14–17%

Panel tilt angle 15°

Optimal ≈ latitude angle. Flat roofs typically 10–15°

Financial Parameters

Electricity tariff ₹7.0/kWh

Annual tariff escalation 3%

India average: 3–5% · Improves long-term savings

System cost per Wp ₹40/Wp

India: ₹35–55 · USA: ₹70–100 · EU: ₹80–120

Annual O&M cost (% of capital) 0.5%

Operation & maintenance: cleaning, inspections, minor repairs

Grid & Subsidy

Grid emission factor

Government subsidy 0%

India PM Surya Ghar: up to 40% · USA ITC: 30%

⚡ India tip: Under PM Surya Ghar Muft Bijli Yojana, residential systems get ₹30,000–78,000 subsidy. Set 20–30% for realistic Indian estimates.

Step 3 — Loss Modeling

🔬 Fine-tune system losses for accurate performance ratio. Defaults are industry-standard values (IEC 61724).

Temperature loss 4.0%

Higher in hot climates. India summer: 5–8% · EU: 2–4%

Inverter losses 3.0%

Modern string inverters: 2–4% · Microinverters: 2–3%

Wiring / DC cable losses 1.5%

Properly designed systems: 1–2%

Module mismatch losses 1.0%

Variation between panels in same string: 0.5–2%

Dust & soiling losses 3.0%

Dry/dusty (India): 3–8% · Humid/rain-cleaned: 1–3%

Shading losses 2.0%

Near-shading from trees/buildings. 0% if fully open sky

Panel degradation rate (per year) 0.5%

Premium panels: 0.3–0.5%/yr · Standard: 0.5–0.8%/yr
