Mexico a Solar Energy Gold Mine

A new report out from Mexico’s energy department, SENER, delves deeply into the nation’s vast solar energy potential, which is well above that of current solar energy leaders Germany and Spain. The report, Solar Energy Sector has a ton of info on the solar potential of Mexico, but here are a number of key findings:

• Only 0.06% of Mexico (in land area) would be needed to power the entire nation from solar energy (according to 2005 usage rates).
• “Mexico’s average solar resources for PV (5 kWh/m2/day) are more than 60% higher than the best solar in Germany (5.4 GW of installed PV).”
• “PV installed in many cities across Northern and Central Mexico has an ‘energy payback time’ (EPBT) of less than two years.”
• “Northern Mexico’s Direct Normal Insolation is equivalent to the best in the U.S. Southwest and in the North African deserts.”

Of course, Mexico isn’t living up to its solar potential yet. “Mexico is seriously underdeveloped in terms of solar energy technologies like solar photovoltaic (PV), concentrating solar power (CSP) and passive solar thermal (i.e., hot water heating),” CalFinder Solar reports. “For example, as of a 2007-08 report – Mexico Solar Installations by Type – there are no concentrating solar power plants in Mexico, and 80 percent of the solar PV installations are not grid-connected. Moreover, 78 percent of the solar thermal installations are for heating swimming pools rather than residential wash water.”

With Mexico City signing historic climate change legislation last week and the “Renewable Energy Development and Financing for Energy Transition Law” (LAERFTE in Mexico) in place since November 2008, hopefully the country will be tapping into its solar resources a lot more soon.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it!! So, we've decided to completely nix paywalls here at CleanTechnica. But...
