Installation of Rooftop Solar Panels on Science Building

Prepared For: College Sustainability Committee, Govt Graduate College Burewala
Date: 26 October 2025
Authors: Energy Management Task Force

1. Introduction

Objective: Assess viability of installing 50 kW solar panels on Daud Science Block roof.
Driver: Reduce grid dependency and align with Green Punjab Initiatives.
Scope: Technical, financial, and operational feasibility over 5 years.

2. Methodology

Evaluation Criteria:

Data Sources:

• Punjab Energy Department solar maps
• Structural audit report
• Vendor quotations (SolarPak, SunraysEnergy)

3. Findings

Options Analysis (Written Summary)

Option A: Monocrystalline Panels

• Financial (ROI): 14% annual return (exceeds 12% threshold)
• Technical Fit: Optimal - No structural modifications required
• Installation Time: 10 days (aligns with winter break)
• Maintenance: 3 hours/month
• Risk: Low hail resistance (mitigated by insurance policy)

Option B: Thin-Film Panels

• Financial (ROI): 9% annual return (below 12% threshold)
• Technical Fit: Partial Reinforcement - Requires roof strengthening
• Installation Time: 14 days
• Maintenance: 2 hours/month
• Risk: High degradation rate (1.5%/year reduces long-term efficiency)

Option C: Building-Integrated PV (BIPV)

• Financial (ROI): 6% annual return (below 12% threshold)
• Technical Fit: Major Retrofit - Full roof reconstruction needed
• Installation Time: 6 weeks (disrupts academic activities)
• Maintenance: 1 hour/month
• Risk: Complex repairs requiring specialized technicians

Key Comparisons

Technical Fit Details

• Option A: Roof load capacity (35 kg/m²) supports panels (28 kg/m² required)
• Option B: Requires +15% steel reinforcement (₨4.2 lakh additional cost)
• Option C: Full roof demolition needed (6-week closure of Science Building)

“Option A delivers Punjab's best cost/kW ratio (₨6.16 lakh) while Option C's aesthetic benefits don't offset its 300% longer payback period.”

Financial Analysis (Option A)

4. Discussion

Key Advantages:

• Exceeds ROI threshold (14% > 12%) with fastest payback period
• Roof load capacity (35 kg/m²) supports panels without reinforcement
• Winter break installation avoids academic disruption

Critical Risks:

• Monsoon Output Drop: 15-20% June-August (solved by grid hybridization)
• Hail Damage: 5% annual probability (₨8,40,000 insurance recommended)
• Regulatory Delays: MEPCO approvals take 30-45 days

Punjab Colleges Benchmark:

5. Conclusions & Recommendations

Verdict: Feasible (Score: 92/100)

Recommendations:

1.   Approve Option A (Monocrystalline) - meets all technical/financial thresholds

2.   Claim Punjab Solar Scheme subsidy before March 2026 deadline

3.   Allocate ₨ 8,40,000 annually for hail insurance

Implementation Timeline:

Success Metrics:

• ≥200 kWh daily generation (non-monsoon)
• 25% reduction in Science Building's grid dependence
• ₨4,20,000 monthly savings

Attachments:

• Structural integrity certificate
• SolarPak quotation (Ref: SP/Q/1526)
• Punjab Solar Scheme guidelines 

"This project transforms our Daud science block into a clean energy hub – paying for itself in under 4 years while reducing carbon emissions equivalent to removing 42 cars from Burewala roads annually."
