Solar power continues to expand in the central San Joaquin Valley, where projects in Fresno and Tulare counties are coming online. Today, PG&E symbolically flips the switch on three power stations near Five Points that will deliver enough solar energy to run 15,000 houses. Here is more from The Fresno Bee.

And here is a report on an interesting project a county away, where Dinuba officials will affix more than 4,700 solar panels to a landfill, and then use the 1 megawatt of power to operate the city's wastewater treatment plant. Typically, those types of facilities are among a city's biggest energy hogs.

Dinuba isn't the first city to use solar energy to decrease power bills at its water treatment plant, and likely won't be the last, as we reported in this blog that outlined similar projects in the Valley - and other possible uses for solar.

Solar is making its way onto rooftops, into agriculture operations and even onto roads. How much it expands remains to be seen, but the potential is sunny, considering California's 33 percent renewables mandate, the falling cost of residential systems and improving technology.

Just yesterday, folks at at UC Merced (oh, how we love UC Merced and its top-notch research programs!) announced a new kind of solar system that doesn't have to track the sun. Read more here in the Merced Sun-Star.

Maybe, Gov. Jerry Brown was right when he predicted a solar revolution in California.
