Oasis™ C1 | Power Plant

Maximized Production High-efficiency technology delivers more

MWh per hectare than a system based

around Conventional Panels1 mounted

on a fixed tilt system.

Higher Capacity Factor Industry-leading tracking technology

delivers capacity factors up to 25%

higher than conventional systems.

Faster Commissioning Pre-manufactured tracker and electrical

systems ensure the plant is quickly

permitted, constructed, and connected

to the grid.

Lower O&M Costs Superior technology and integrated

design reduces operations and

maintenance costs.

A Proven Performance Reliable technology with an unparalleled

track record minimises risk and ensures

project bankability.

SunPower™ Oasis™ C1 Power Plant A Ground Mount Solution For A Lower LCOE

The SunPower™ Oasis™ C1 Power Plant combines the best solar panels

and tracking technologies with a simplified, modular approach to deliver

reliable utility-scale solar energy. Engineered as a complete turnkey

system, the Oasis C1 Power Plant maximizes energy production and

requires less land to create the same energy output as conventional

solar power plants.

With more than 10 years of experience in the engineering, construction

and operations of utility-scale power plants, SunPower has transformed

power plant development from a piecemeal process into a streamlined,

efficient installation with the Oasis. Each Oasis C1 1.5 MW power block

features SunPower high-efficiency solar panels2 mounted on proprietary

single-axis trackers, DC collection, and a pre-configured AC inverter

station that includes a medium voltage transformer. The C1 power

blocks can fit numerous site topographies and are easily scaled from

10 MW to over 500 MW.

Providing reliable, long-term production, the Oasis C1 ensures that

customers enjoy a lower total cost of energy and a strong return on

their investment.

1.“Conventional Panel” is a 240W panel, 15% efficient, approx. 1.6 m2, made with Conventional Cells. ”Conventional Cells” are silicon cells that have many thin metal lines on the front and 2 or 3 interconnect ribbons soldered along the front and back.2.
