The Waaree ARUN series (WS-100 to WS-235) are silicon modules designed for stable operation in typical real-world operating conditions - from domestic installations to utility and off-grid applications. A key feature is polycrystalline cell technology, valued where predictable performance and a good quality-to-cost ratio of the entire system are important. In practice, this means easier design of installations with repeatable yields, without overpaying for solutions you don’t use.

A major advantage of the series is the wide range of power options and voltage configurations, enabling the modules to be adapted both to traditional rooftop installations and to battery systems, lighting, monitoring, or recreational facilities. Users gain greater design flexibility - it’s easier to match the number of panels to the inverter or charge controller, minimizing losses from mismatching.

This is an option for investors who expect proven construction and predictable operation, rather than marketing promises.

Common questions

6 answered
What's the difference between the polycrystalline technology used in Waaree ARUN panels and popular monocrystalline modules?
Polycrystalline cells in the ARUN series have slightly lower efficiency than monocrystalline (around 15.6%), but offer more predictable performance and lower cost per Wp. For installations where roof area is less critical than budget - such as residential or utility projects - this is a sensible trade-off. The power temperature coefficient is -0.39%/°C, a typical value for this technology.
What's the maximum power output in the Waaree ARUN series, and how do I choose the right variant for my system?
The series spans WS-100 to WS-235, with the most powerful modules reaching up to 220 Wp. A wide range of power ratings and voltage configurations (36-cell and 72-cell versions) makes it easy to match panel count to a specific inverter or charge controller - whether for a rooftop installation or a smaller battery-based system powering lighting or monitoring equipment.
What warranty applies to Waaree ARUN panels?
The manufacturer provides a 5-year product warranty covering material and workmanship defects, plus a 10-year power performance warranty. This is a standard level of protection for polycrystalline modules in this price segment, sufficient for most residential and utility installations, though shorter than premium series that offer warranties extending to 25-30 years.
Are Waaree ARUN panels suitable for off-grid and battery-based systems?
Yes, this is one of the series' main use cases. Thanks to the availability of lower power variants and different voltage configurations, ARUN modules integrate easily with MPPT or PWM charge controllers in off-grid setups powering lighting, monitoring, pumps, or recreational properties. The flexibility in power selection minimizes losses from mismatching the panel to battery capacity.
Do Waaree ARUN panels perform well in low temperatures and harsh weather conditions?
Yes, the modules are rated for operation between -40°C and 85°C, making them suitable for continental climates with cold winters. The design resists potential-induced degradation (PID), and tempered low-iron glass provides resistance to hail and snow loads. The panels also have confirmed resistance to salt mist and ammonia exposure.
Is Waaree a proven Tier 1 manufacturer, and is it worth buying panels made in India?
Yes, Waaree is classified as a Tier 1 manufacturer, meaning it meets the financial stability, production scale, and bankability criteria required by project financiers. The company is headquartered in India and is one of Asia's largest PV module manufacturers, translating into competitive pricing while maintaining quality standards comparable to Chinese producers.
