Stion Saves $138M vs Chinese Panels on Proposed Wall Prototypes

Just this week, the US Customs and Border Protection Agency awarded contracts to four companies to build prototypes for the proposed solar border wall, which is expected to cover 1,000 miles of the U.S. border with Mexico.

A solar border would benefit both the U.S. and Mexico by powering cities on either side in an environmentally safe and cost effective manner. The wall has been designed so that 9,823,256 Stion modules would affix to the mid-section and top of the border wall for a total of 1.5GW, more power than would be provided by a nuclear facility. 1.5GW would create over 1000 factory jobs at Stion’s manufacturing facility in Mississippi. With Suniva and SolarWorld AG’s recent insolvency, Stion is one of only three USA MADE options left, should they integrate solar into the border wall design while heeding President Trump’s executive order to “Buy American.”

PVsyst performance comparisons demonstrate that a Stion array would out produce a Chinese panel array by 5%, resulting in $186M more in savings compared to a Chinese system over 25 years.  Over a 25 year period a Stion array would generate $4.2B in savings whereas the wall is expected to cost at least $8B, according to Congress.*

A 1.5 GW Stion solar wall system would produce 2,926 GWh of electricity per year, which is 129 more GWh per year in comparison to a Chinese panel system.

Stion’s frameless modules are ideal for the solar border wall due to our industry leading temperature coefficient and excellent performance in the hot regions of the SW US. The frameless design of the modules also minimizes cleaning as there is no debris buildup, which will help minimize operations and maintenance costs.

Stion module efficiency vs. Chinese module efficiency:

Stion modules outperform Chinese modules due to an industry leading temperature coefficient of -0.26% / °C, durable glass on glass module structure, minimal degradation in extreme weather conditions, leading up to a 5% better performance advantage in hot climates.

Chinese c-Si modules are designed with a less durable polymer (plastic back sheet) and have an average temperature coefficient of -0.4% / °C.

*Stion calculated 25 years of savings using an annual electric inflation rate of 2.9%.
