O&M Case Study – Sasonbi Solar
“A month after installing our Trinasmart system we got an alert in our email notifying us that there was a “Low PV string power.” I went to the portal and I noticed immediately one string was blackened and the voltages were all zero for all the panels in that string. Yet all the other panels were delivering throughput within expectations. So we reckoned right away that the problem was with that specific string only. Early the following morning, we inspected and found out that the fuse for that string was broken. We were able to fix it within a day of the incident thanks to the Trinasmart monitoring. The e-mail notification from Trina was such a great help in knowing the situation almost immediately.” - Dante Briones, CEO Sasonbi Solar

Trinasmart Gets You More Watts From Every Bin
• Modules in the factory are binned to a certain accuracy (generally +3%)
• An equal number of +3% modules will be found in a bin as 0% modules, but when strung together they all act like 0% modules
• With Trinasmart a +3% module will not get dragged down by a 0% module
• A +3% bin will effectively give the customer an additional 1.5% more watts
+ 3%
+1.5% Watts =

• Trinasmart can increase ground coverage ratio without sacrificing energy yield
• Inter-row shading is mitigated by panel-level MPPT
• In general modules can be placed 4% closer without compromising energy yield

Maximum Energy Harvest
Shade Affects 38 modules more than 50% Shade Affects 9 modules more than 50%
Traditional System
Causes of mismatch • Module output is limited
by the lowest string amperage
• One underperforming module can bring down an entire string
• Allows each module to operate independently
• The more mismatch in a system the more extra energy delivered relative to a traditional array
Shading ‐ Shaded modules drag
down others
Output variance ‐ In each power bin, a
+0W module will drag down by a +5W module
Degradation variance ‐ Faster degrading
modules drag down others as they age
Mismatch drags down a string Trinasmart corrects mismatch

Design Flexibility
Different roof angles on the same inverter MPPT
Inter-row shading is mitigated by panel-level MPPT
Maximum roof coverage on non-ideal sites
Uneven strings in parallel
Closer module placement without compromising energy yield

Losses from mean-shift degradation

Losses from variable component
• Module degradation is not uniform
• This creates module mismatch that grows over time: approximately 0.75% increase in standard deviation each year
• In year 5, this represents 1-2% additional losses, which grow to ~4% in year 10 and 12% in year 20

Energy Harvest Case Study – Tucson Electric Power
Location: Tucson, Arizona
System 1: 105kW w/ Tigo
System 2: 108kW w/o Tigo
Trinasmart’s technology was retrofitted onto a 12 year old system operated by Tucson Electric Power. Over the course of a one month trial comparing two systems next to one another the Impedance Matching Technology yielded 9.7% more energy per kW as compared to the normal array. “Having Tigo Energy optimizers installed
on half the array allowed us a unique view into system performance and how optimizers have been able to change the performance of the array. The difference in Performance of these side-by-side and nearly identical arrays was striking.”

Trinasmart – The Safest Solar Available
Module level arc fault detection and switch off
Module-level disconnect for maintenance and emergency response
Automatically when the electricity supply is switched off Or manual via the PV Safe button or remotely via the web
Low-voltage shutoff mode NEC 2014 fire code compliant
Expected Draft in October 2013 NEC 2014 article 690.12 (Expected 10/2013)

Safety Funtionality
Note: Trinasmart can deactivate modules for safety by:
1. Pressing the red button on the MMU
2. Turning off the AC breaker to a home (Trinasmart modules sense that the inverter and MMU is down and automatically switch off)
3. Manually turning it off online on the Trinasmart software
