750 KW Solar Project for Vicco Laboratories

Vicco Laboratories Advances Sustainability with 750 KW Rooftop Solar Installation

Vicco Laboratories, located at S-89, MIDC Hingna, Nagpur, Maharashtra, is one of India's most trusted and iconic Ayurvedic brands with a legacy of over 70 years. Known for creating the world's first Ayurvedic face cream Vicco Turmeric — the company has been a pioneer in promoting natural, herb-based personal care products across India and globally.

The Nagpur facility houses quality control labs, testing and analytical instruments, and research operations that run continuously throughout the year, requiring reliable and uninterrupted electrical power. With escalating electricity bills and Nagpur receiving over 300 sunny days annually, Vicco Laboratories made a strategic decision to invest in rooftop solar energy.

Chirayu Power Pvt. Ltd. proudly collaborated with Vicco Laboratories to execute a 750 KW grid-tied rooftop solar power plant at their MIDC Hingna facility.

Technical Specifications

• Total Capacity: 750 KW (Kilowatt)
• Solar Panels: Rayzon Solar 585 Wp (N-Type TOPCon Technology)
• Total Number of Panels: 1,282
• Inverter Brand: SolarEdge (Optimisation Inverter)
• Inverter Configuration: 100 KVA × 6 Units

Why Rayzon Solar 585 Wp N-Type TOPCon Panels?

• Higher Energy Yield: N-Type TOPCon technology delivers up to 5–7% more generation than conventional P-Type panels
• Bifacial Design: Captures reflected and diffused light from the rooftop surface — increasing effective yield by 5–15% over monofacial panels
• Better High-Temperature Performance: Lower temperature coefficient means less efficiency loss during Nagpur's peak summer months (45°C+)
• Lower Degradation Rate: Less than 0.4% per year — ensuring higher output over the full 25-year panel lifespan
• Half-Cut Cell Technology: Reduces resistive losses and improves performance under partial shading conditions

Why SolarEdge Optimisation Inverters?

• Module-Level Monitoring for real-time panel-by-panel tracking via SolarEdge portal — accessible on mobile and web
• Power Optimiser Advantage: SolarEdge S1200 ensures each panel pair operates at its individual maximum — one underperforming panel does not reduce output of the entire string
• Partial Shading Protection: Eliminates the 'weakest link' problem common in traditional string inverter setups
• 25-Year Optimiser Warranty: Industry-leading warranty on the S1200 power optimiser
• Enhanced Safety: Arc fault detection and remote shutdown capability for safe operations
