Editor’s Note: The is a guest contribution by Edward Fenster, CEO and co-founder of SunRun. This is the fifth post in a series from the CEO’s of major solar companies. You can follow the complete series here.

As solar power and other renewable energy sources grow, so does awareness and debate about the role of renewable energy certificates (RECs). As the CEO of SunRun, which is the [...]

It’s easy to think that solar panels can do no wrong— after all, they will help lead us out of our energy crisis, right? Unfortunately, these shining beacons of hope produce toxic e-waste just like cell phones, TVs, and computers. A report released today by the Silicon Valley Toxics Coalition admonishes the solar industry to face its e-waste problem head on or risk “repeating the mistakes made by the microelectronics industry.”

Solar energy is necessary for our transition to a sustainable economy, but a recent study in Geophysical Research Letters suggests that the industry may be harming the environment. Nitrogen Triflouride (NF3), a greenhouse gas used by the semiconductor industry to clean the chambers where silicon chips are produced, has 17,000 times the globe-warming capacity of CO2. Now researchers believe that emissions of the gas are up to 4 times higher than previously thought—perhaps as high as 16 percent.

The Solar Electric Power Association (SEPA) has outlined four easy steps to a thirty fold increase in the size of the US solar power industry between 2009 and 2016, leading to over $230 billion worth of investment and the creation of 440,000 permanent jobs.

John Sedgwick is the Co-founder and Vice President of Solaicx, a company that manufactures silicon ingots and wafers for solar electric (PV) panels. They are then supplied to solar panel manufacturers across the globe.

Solaicx began production at their new manufacturing plant in Portland, Oregon at the end of 2007. While current capacity of the plant is 40 MW, production will increase to 180 MW in the future.

CleanTechnica: What kinds of general trends have you seen in the solar industry as a whole?

John Sedgwick: The general objective of the entire industry is to reduce costs. What we see in markets across the world is, as you lower the levelized costs of solar electricity down to the levelized cost of traditional electricity, the markets just go vertical. When you look over time, the industry is doing dramatically well at reducing costs.That’s even when you take into account some significant challenges, things like polysilicon shortages and other shortages that have popped up as a direct result of a market that has been growing at 35%, 40%, and 50% a year have caused shortages that have increased some costs in the chain. Yet, because of manufacturing efficiencies, conversion efficiencies, and economies of scale, the industry has been able to hold the line on any cost increases and has done pretty well at reducing costs.
