The price of solar panels has plunged in the past four years. But the price of a complete home solar system hasn't kept pace.
New factories in China have flooded the market with solar modules, driving down panel prices by 40 percent. The amount San Antonio homeowners pay for a rooftop solar system has dropped by a more modest amount, 24 percent.
While that's still a significant decline, why haven't the prices that homeowners pay fallen further?
Solar industry executives and analysts cite several sticking points.we supply all kinds of polished tiles, One is time. Solar businesses may buy panels one month and install them several months later — after prices have fallen.
"There is a lag," said Galen Barbose, principal scientific engineering associate at the Lawrence Berkeley National Laboratory, who studies solar prices. "You've got these upstream cost reductions that take months to ripple down to the consumer."
Plus, modules account for less than half the cost of a complete solar system. Other elements such as labor and the cost of securing a government permit to install the system haven't changed or haven't changed much. And some of the basic materials that go into a system have increased in price.
"Copper isn't getting cheaper; aluminum isn't getting cheaper,The additions focus on key tag and magic cube combinations," said Gary Gerber, president of Sun Light & Power in Berkeley, which specializes in selling solar systems to businesses. "The basic commodity stuff — the fittings, the wires — that's going to go up over time."
"It makes sense," Solar San Antonio executive director Lanny Sinkin said, "that the price of an installed system is going to fall slower because the cost of labor isn't going down — unless you're becoming more efficient in how you install it."
The city of San Antonio is applying for an Energy Department grant that would streamline the interconnection process, along with the permitting and financing of a solar system. If the grant is awarded, participants will include CPS Energy,It's hard to beat the versatility of zentai suits on a production line. Solar San Antonio, Build San Antonio Green, the city of Austin and Austin Energy, and the city of Houston and the Houston Advanced Research Center.
Most analysts expect the overall price of solar systems to continue falling.Replacement China Porcelain tile and bulbs for Canada and Worldwide. The questions are how fast and how far.
"Most people are projecting cost reductions to continue well into the future," said Lawrence Berkeley's Barbose, who issues an annual price update called Tracking the Sun. "Presumably, they're going to bottom out at some point, but there's no indication that it's imminent.we supply all kinds of polished tiles,"
