The biggest solar power system in the Pacific Northwest is ready to be switched on.

Portland General Electric announced Monday that it had finished a $14 million solar project it began in March. The array, spread out over the roofs of seven distribution warehouses, comprises 2.4 megawatts of panels.

"This installation shows the potential for cultivating the rooftop real estate of Oregon to generate clean, renewable energy," Energy Trust of Oregon’s director of energy programs, Peter West, said. The trust is supplying more than $2 million in incentives for the project.

This isn’t the first time Oregon has been in the news for solar energy. Solexant, a San Jose, California-based solar panel manufacturer, announced last week that it would build a panel assembly facility in Gresham, a town near Portland. The Portland Tribune quoted Gresham’s mayor, Shane Bemis, as saying that the town was "tremendously excited" to welcome Solexant.

The uptake of solar power in Oregon shows that solar can work almost anywhere. Even in Oregon – which has a much cloudier climate than California or Arizona – generating energy from the sun is possible.
