About product

Trina Solar 415W is a PV module that uses 144 half-cut cells manufactured using proven by time technologies. The model’s reliability, high efficiency, PID resistance and high wattage make it a good choice for commercial and industrial use, but residential clients can also reap the benefits it has to offer. Among the model’s strong sides are BOS costs reduction and improved low-light performance.

  • Power Output: 415 Watts
  • 144 Cell, Monocrystalline
  • 35 mm silver frame, white backsheet
  • 1500 Volts Max Voltage

Outstanding 20.4% Efficiency

Trina Solar 415W is a monocrystalline module with a 20.4% efficiency, which is a long stretch ahead of what conventional panels have to offer. Trina Solar 415W has a low temperature coefficient of -0.36%, which means that the module’s efficiency decreases just 0.36% for every 1.8°F above 77°F. This helps to maximize the final energy output.

A panel that will weather any storm

This model is certified to work under harsh conditions. Its front side can resist a load of up to 5,400 Pa and the rear has been tested for 2,400 Pa. Special coating makes the modules resistant to salt, acid, sand and ammonia.

Product and performance warranty

With this panel, light induced degradation is less of a threat: you can expect an output drop of up to 1.9% in the first year of use, but starting from the second year it won’t exceed 0.6%. Finally, after year twenty five the panel will perform at 83.1% of its nameplate capacity or slightly better. The manufacturer also offers a 12 year product warranty.

I have them installed in Sacramento Valley. The sun is very active here and they generate a lot of power. I plan to add more of these to my setup in the future

Great customer service! I bought them for a project I’ve been working on since spring. They were bulkier than I expected but true to the dimensions on the website. I’m satisfied with the quality, but the panels could be smaller

I bought 12 of these for ground mounting on a farm. So far so good. The modules arrived in time and undamaged. It was a pleasure to deal with you guys

Yes, the panels are good both for ground mounted and rooftop projects.
How are half-cut cells better?

Among other things this technology reduces resistive losses, helps with the hot spots and improves low-light performance.
