Utility Scale Needs

Win deals with low PPA’s

Accelerate construction

Simplify labor force & logistics

Maximize long term system yields

Maintain high quality and mitigate risk

Low Priced PPAs: Simple ballasted mounting and continuous

automated installation technology lowers system cost for any site

New project opportunities due to extruded concrete design:

Brownfields and Landfills: non-penetrating concrete rail

eliminates constraints posed by traditional posts

Corrosive and rocky soil: concrete rail, adhesives and coated

metal legs are highly corrosion resistant

High wind: permits construction on sites with high wind loads that

prevents the use of conventional racking

Excessive soiling: Low-cost SPOT robot technology for cleaning

mitigates output and cost risk related to projects near high pollutants

or in high dust areas

Soiling and Energy Loss

*Source: “Direct Monitoring of Energy Lost due to Soiling on First Solar

Modules in California” by J. Riley Caron and Bodo Littman, IEEE 2012

Problems • Limited data available

• Highly location dependent

• Energy loss varies from 1% to 40% or more

• Manual cleaning = high cost and few cycles

• Unpredictable weather can negate cleaning

June – Sept*: highest soiling levels

during months of highest energy value

MENA Experience:

"Its dust, dust and more dust! O&M companies need to develop a portfolio of tested and developed

tools and solutions from dry type to wet type cleaning.“

- Dr. Raed Bkayrat, KAUST, Jeddah, Saudi Arabia

SPOT is a key differentiator in MENA and other

markets with desert conditions

“For example, dust accumulated on photovoltaic panels

after six months in the Middle East can reduce their

effectiveness by 40 percent.”

- Jeff Munoz, Chevron Qatar PM
