Waaree Arun Series are advanced photovoltaic modules utilizing n-type TOPCon cell technology, which significantly increases energy conversion efficiency in challenging lighting conditions. They focus on effectively solving the problem of power loss at high operating temperatures, which translates to more stable yields on hot days. The use of larger silicon wafers combined with high bifacial efficiency ensures that these panels generate additional energy from both sides of the module, maximizing the yield from every square meter of surface area. By using high-transmittance glass with an anti-reflective coating, this series handles the Polish, often cloudy sky perfectly, capturing more diffused light than standard solutions. It is an optimal choice for projects such as utility-scale solar farms and demanding business installations, where lowering the LCOE is key. Importantly, the Arun series shows minimal susceptibility to LID-type degradation, which, combined with heavy-duty mechanical resistance to extreme weather phenomena, places it at the forefront of premium products in terms of longevity and investment security.

Common questions

6 answered
What is the maximum power output of the Waaree Arun Series panel?
Arun Series modules reach a maximum power of 235 Wp thanks to n-type TOPCon cells. This provides a reliable base for stable installations where predictable energy yield matters, even at the high module operating temperatures typical of Polish summers. Lower thermal losses let the panel maintain higher efficiency than comparable modules built on older PERC technology.
Are Waaree Arun Series panels bifacial (double-sided)?
No, the Arun Series consists of monofacial modules — energy is generated only from the front side of the panel. However, the high-transmission glass with an anti-reflective coating improves diffuse light capture, boosting yield on cloudy days even though there is no rear-side power generation.
What warranty comes with Waaree Arun Series modules?
The manufacturer provides a 5-year product (materials) warranty and a 10-year power output warranty. Waaree is a Tier 1 manufacturer, meaning proven financial stability and bankability — an important factor when applying for loans or subsidies for PV installations.
How does TOPCon technology in the Arun Series differ from standard PERC cells?
The n-type TOPCon cells used in the Arun Series have a lower temperature coefficient than classic PERC cells, meaning smaller power losses at the high module temperatures reached in summer. They also show lower susceptibility to LID degradation, helping the panel maintain its rated efficiency for longer over its service life.
Will Waaree Arun Series panels perform well under Poland's frequently overcast skies?
Yes, thanks to high-transmission glass and an anti-reflective coating, Arun Series modules effectively capture diffuse light, which dominates in Poland for most of the year. Combined with the low temperature coefficient of TOPCon cells, this results in a more stable energy yield regardless of weather conditions.
Is Waaree a proven, bankable solar panel manufacturer?
Yes, Waaree Energies is an Indian Tier 1 manufacturer with a long-standing presence in the global PV market. Tier 1 status confirms the company's financial stability and its ability to honor long-term warranty commitments, which matters when financing an installation through a loan or subsidy program.
