Lessons from PV Tech’s unscientific Section 201 straw poll at SPI

The results of our first (last) ever attempt at polling are in and they are very much predictable. But regardless of popular opinion, it's worth considering the views of those not speaking up. While the industry is largely against Section 201 trade measures, that alone is not the most likely reason the ITC might choose not to recommend hefty tariffs come November.

The Value Proposition of Using High-Efficiency Mono-Si PERC Modules

In the past the value proposition of solar modules has been primarily about the lowest price ($/Watt) via the lowest manufacturing costs of conventional multi-Si modules. In the last few years, PV system cost has decreased significantly. In the meantime, PV module costs had dropped at a faster pace than Balance of System (BOS) costs, resulting in PV modules accounting for a smaller and smaller percentage of overall PV system costs.

SPI 2017: Solar modules pushing the bar on performance

Updated: With the solar industry transitioning to high-performance products backed with innovation, Solar Power International 2017 in Las Vegas is showcasing an ever increasing portfolio of solar modules exceeding 300 watts in the standard 60-cell format. However, 72-cell modules exceeding 360 watts are also entering the mainstream and 400 watts is just around the corner. Driving the high-performance wave is PERC (Passivated Emitter Rear Cell), bifacial and the migration to 5 busbars and beyond, whether with multicrystalline or monocrystalline wafers. The growing use of half-cut and multi-cut cells that reduce cell to module losses, boosting overall performance are also becoming mainstream as well as heterojunction (HJ) modules.
