From the moment a PV module is born
on the production line
it vows a 30-year linear power warranty—
a pledge to endure the test of time
Across its three-decade lifespan
what trials might “I” face?
I may confront the fury of blizzards, salt-laden hurricanes
and the scorching crucible of deserts
Yet the “extreme trials” endured in the lab—
wet leakage tests, hail impacts, PID under high heat and humidity
mechanical dynamic loads, static sandbag pressures
have already forged me into storm-defying steel
Act I Ballad of the Frozen North
Wilderness snow can crush steel towers, yet I must withstand assaults from “hail assassins.” In the lab, hailstones 35mm in diameter, each weighing 20.7 grams, strike 11 precise points on my surface at 27.2 meters per second. Only when my glass remains unbroken do I earn the title “qualified.”
During dynamic load tests, robotic arms like giant hands press upon me relentlessly—pressure oscillating between ±1000Pa and ±2400Pa, five times per minute, for 1,000 cycles. My aluminum frame creaks, yet the backsheet and cells cling tightly, unyielding.
Humans call this “unbreakable fortitude.”
ActII Life Adrift on Saline Seas
Should I stand by the seaside, the salty sea wind cuts like a blade. Yet humanity has prepared me well: under 1500V voltage and 25°C water, my insulation withstands damp leakage currents. Moreover, I must pass rigorous PID testing under high temperature and humidity, ensuring that over a 30-year marine lifecycle, my degradation never exceeds 3%, with an annual linear power decline of no more than 0.5%. Thus, I have earned TÜV certifications for ammonia resistance (IEC 62716) and double-glass salt mist corrosion (IEC 61701).
Act III Ode to the Desert
Under the scorching sun of tropical deserts, my every inch is baked as if in a furnace. But what you may not know is that humans expose me outdoors for relentless sunlight— 1 month of ultraviolet radiation. In the high-low temperature cycling test, I endure the polar freeze of -40°C and the blistering heat of +85°C, alternating every 6 hours for 200 cycles. Though my silicone material stretches and contracts repeatedly under thermal expansion and cold contraction, the solder joints in my junction box remain unshaken, steadfast as Mount Tai.
When I pass all trials, humans engrave my nameplate:
“30-Year Linear Power Warranty.”
And someday, I may journey to
snow peaks, remote islands, or desert wastes
to fulfill my three-decade destiny
