Navitas NS 250 250W Polycrystalline 60-Cell Solar Panel
Model NS 250 | Multi Crystalline | 60 Cell Module | Monofacial | 1500V System Voltage
Product Overview
The Navitas Solar NS 250 polycrystalline solar panel delivers reliable 250W performance for rooftop and large scale systems. This 60 cell module is engineered for stable output, long service life and consistent efficiency in varied Indian climates. Module efficiency reaches 15.39 percent at standard test conditions, giving strong energy density for residential and commercial roofs. A wide power range from 250 to 280 Wp is available in the NS series, supporting flexible system design and future expansion. The panel uses anti reflection coated glass to improve light capture and enhance performance in low light conditions. An anodized aluminium frame and tough 3.2 mm glass help the module handle demanding outdoor environments over many years. With best in class temperature behaviour and a nominal operating cell temperature of 45 degrees, energy yield stays dependable. The NS 250 polycrystalline panel from Navitas Green Solutions Pvt. Ltd. is an excellent choice for customers seeking bankable performance. It is designed and manufactured in India, supporting local projects, EPCs and installers with a proven, ALMM listed module series. Careful current binning improves string performance, helping inverters operate closer to their optimal working range through the day.
Key Benefits
Stable 250W power output: Rated power of 250 Wp provides predictable production for grid tie and off grid systems. It supports balanced string design across common inverter input ranges.
Proven multi crystalline technology: Polycrystalline cells offer robust performance and field reliability. They deliver solid energy yield across real world operating temperatures and irradiance levels.
Optimised temperature performance: Low temperature coefficient of power at -0.38 percent per degree Celsius limits losses on hot days. Output remains more stable in peak summer conditions and under strong sun.
Enhanced low light generation: Anti reflection coating glass improves light transmission in morning, evening and cloudy conditions. This helps extend the daily production window and increase annual energy yield.
Long term warranty protection: A 10 year product warranty is combined with a 25 year linear performance warranty. Power is warranted to 90 percent at 10 years and 80 percent at 25 years for long term peace of mind.
Rugged mechanical design: Anodized aluminium frame, 3.2 mm ARC glass and IP68 junction box increase durability. The module is engineered for outdoor exposure, harsh weather and long service life on roofs and ground mounts.
How It Works
Each Navitas NS 250 polycrystalline solar panel converts sunlight into DC electricity through sixty interconnected cells. When sunlight hits the multi crystalline cells, an electric field is created and current flows through the internal bus bars. The module operates at a maximum power point of 250 Wp, with 30.5 V Vmpp and 8.2 A Impp under standard test conditions. An anti reflection glass layer increases the usable light that reaches the cells, even under hazy or diffuse conditions. Generated current passes through three bypass diodes in the junction box, which protect the module during partial shading. DC power leaves the panel through pre fitted solar cables and MC4 compatible connectors and then feeds into the inverter. The inverter converts DC power into AC power that can be used on site or exported to the grid through net metering. Performance remains stable across an operating temperature range from minus 40 to plus 85 degrees Celsius. Over decades of operation, degradation is limited, backed by a linear power warranty and strict quality control.
Photovoltaic energy conversion: The multi crystalline silicon cells absorb photons from sunlight and free electrons within the material. An internal electric field directs these electrons to form a continuous DC current, which flows at the module operating voltage and current levels defined in the electrical data.
Maximum power point operation: The NS 250 module is designed to operate close to its maximum power point through inverter MPPT tracking. With power tolerance of 0 to plus 2 percent, actual field output can slightly exceed the nameplate rating under strong irradiance, improving overall system yield.
System integration and protection: The panel connects into strings sized for up to 1500 V DC systems, reducing cabling and BOS costs. Three integrated bypass diodes limit heat build up on shaded cell strings, while the IP68 junction box and robust frame protect electrical connections against dust, moisture and mechanical stress.
