Renewables MMI Up, Silicon Seeing a Boost From Solar Adoption

by on

The Renewables MMI got a boost from increasing steel prices and resilience in solar silicon to increase 3.8% to 54 this month.

This is likely not related to the broader rally in metals prices as renewables are fairly niche and this sub-index is still trading well within the low range we’ve seen it inhabit for most of the last year. Many renewables aren’t even publicly traded and we have long lamented the effect government incentives have on hiding and keeping prices low for metals and end products subsidized at several points in the supply chain such as silicon.

So, to get a real feel of what’s going on out there it’s sometimes necessary to look at other metals used in the end products. For solar panels, that’s our precious/industrial friend, silver.

The average solar panel actually uses about two-thirds of an ounce of silver. That might not sound like a lot, but at around $15 an ounce on the MetalMiner IndX, U.S. silver contributes more to the cost of a crystalline photovoltaic silicon solar panel than it does to most other industrial products that use silver. Laptop computers use way less than half-an-ounce of silver while a cell phone contains a minute 200-300 milligrams of the shiny metal.

Silver Breaks Out

Silver has broken out from the lows of 2015 and has joined its precious cousin gold in seeing its value increase exponentially this year. Unlike gold, though, silver has a ton of renewable applications. The solar industry uses about 5% of the world’s annual silver supply, or an estimated 52.4 million ounces.

Demand Effect

Some might say an increase in the price of silver doesn’t have any direct correlation to the rise in silicon prices or any real connection to solar adoption, either. While this has a grain of truth to it, such a healthy increase in a related component metal can’t entirely be discounted. Silver is actually the primary ingredient in PV cells, and 90% of crystalline silicon PV cells use a silver paste. As a regularly tracked commodity, silver’s demand is relevant. Not just in the U.S. but in massive solar adopters China and India, as well.

That being said, a big price spike in silver could keep adoption of the technology low, too, but that spike would still be a better indicator of loss of demand than some of the prices of subsidized metals. That and, of course, the undeniable rally in steel products being used in all of those wind turbines and solar panels.

Actual Renewables Prices

Silicon increased to $1,876.16 a metric ton from $1,846.41 in March, a jump of 1.6%. Chinese steel plate jumped from $360.13 per mt last month to $435.70 per mt this month, a leap of 21%. Korean steel plate increased to $402.20 per ounce this month, up from $331.14 an ounce in March, another 21% increase.
