As global demand goes up for energy, more and more countries are increasing their solar power production.

Solar Power Taking Off

Solar power is on the rise! According to the Worldwatch Institute, global production of photovoltaic cells increased 51 percent in 2007 to 3,733 megawatts. Germany leads the charge, producing 1,063 megawatts of solar power cells in 2007. China came in second with 820 megawatts and Spain in third with 425 to 650 megawatts. Meanwhile, here in the U.S., production rose 48 percent from 2006 to 266 megawatts. That's an admirable percentage rise but a fall from grace; the U.S. once led the world in photovoltaic cell production. There is hope however—U.S. manufacturers are focused on the "next wave" of solar production by accounting for two-thirds of global thin-film production, an advanced technology trend. With the cost of production consistently falling, it is predicted solar electricity will become cost-competitive with conventional power in many parts of the world in the next several years.

Solar Power panels are still too expensive

08/29/2008 11:42 AM mjdonovan

I recently investigated adding solar panels to my home and was less than impressed with the costs.

There are a couple of websites that actually provide online tools to aid in calculating roof solar panels and associated hardware for your specific home needs/goals.

Using these tools, I determined it would take about 30-35 years to break even on the investment, however the warranty on the panels was around 25 years.

In my opinion the ROI is too long, and the warranty needs to be at least as long as the time it takes to recover the costs.

Solar panel technology is improving and I think it is an excellent complementary source of power to the home. However, prices still need to drop before this market really takes off.
