ENGINEERING CHALLENGE & SOLUTION

Technical Execution Strategy

Challenge: Load Balancing

The tea processing facility operates 24/7 with peak loads during processing hours. Traditional grid integration could cause voltage fluctuations.

Solution

Implemented advanced DG synchronization with MFM (Metering Cum Monitoring) & CT (Current Transformer) integration. This ensures seamless load balancing between solar generation and diesel generators with zero grid export protection.

Challenge: Rooftop Constraints

Limited rooftop space with structural capacity concerns. Required optimal module placement without compromising facility operations.

Solution

Designed short-rail mounting assembly with mid & end clamps for flexible configuration. Used bifacial modules to maximize energy generation from ground reflections, achieving 15-20% higher efficiency.

Challenge: Weather & Safety

High humidity and monsoon rainfall in tea-growing regions. Required industrial-grade safety systems and corrosion protection.

Solution

Implemented SS304 safety lines, ESE lightning arresters, dual AC/DC chemical earthing, and EPDM shock absorbers with waterproofing. All cabling in UPVC conduit pipes for maximum protection.

Challenge: Operational Continuity

Zero downtime allowed during installation. Required minimal disruption to processing operations.

Solution

Phased installation approach with modular deployment. GI walkways with dedicated maintenance access routes. Live monitoring system provides real-time alerts, enabling predictive maintenance with zero unplanned downtime.

FREQUENTLY ASKED QUESTIONS

Project-Specific Information

Our zero-export device with MFM & CT integration automatically balances load between solar generation and diesel generators. During peak solar hours, the system prioritizes solar energy. When solar generation is insufficient, the DG seamlessly takes over without any interruption. This prevents grid export and optimizes fuel consumption.
The 460kW system is expected to generate 5.52 lakh kWh (552,000 units) annually, based on average solar irradiance in the region (4.2-4.5 kWh/m²/day). Actual generation may vary by ±10% based on weather patterns, module cleanliness, and operational factors.
Our system is designed for high-humidity and high-rainfall regions. All electrical components are protected with EPDM shock absorbers and waterproofing. Cabling is housed in UPVC conduit pipes. The system automatically handles variable cloud cover and rainfall, with DG taking over during extended cloud cover. Regular cleaning (2-4 times/year) optimizes performance.
Our Suraksha Plus plan includes comprehensive maintenance: professional panel cleaning (2-4 times/year), electrical system checks, inverter servicing, and monitoring system updates. Cost is ₹308,200/year (₹670/kW/year for 460kW). This covers 100% peace of mind with daily WhatsApp generation reports and monthly/yearly analysis.
With 5.52 lakh units annually and current electricity costs, the payback period is typically 3.5-4 years. Additionally, you benefit from 40% accelerated depreciation from Year 1 under Govt. of India policy, plus 20% additional depreciation for manufacturing units. This significantly reduces tax liability and improves ROI.
Yes, our installation includes premium solar insurance (5-year comprehensive warranty on equipment). Coverage includes manufacturing defects, workmanship issues, and weather-related damage. Panel warranty is 25 years with performance guarantee. We handle all insurance documentation and claims assistance.
Our live monitoring system provides real-time data through a mobile app. You receive daily generation and savings updates on WhatsApp, monthly performance reports, and yearly analytics. The system alerts you to any faults instantly, enabling rapid response. Data is logged every 15 minutes for detailed analysis.
Tea processing facilities may be eligible for: 40% accelerated depreciation (Year 1), 20% additional depreciation for manufacturing, state-specific subsidies (varies by location), net metering benefits, and GST benefits (5% on equipment). We assist with all subsidy documentation and approval process. Contact us for location-specific details.
