There's a lot of physics at play with a photovoltaic panel. Two examples:
- The conversion of solar radiation into electricity.
- The constant gravitational downward pull on prices.
Actually, scratch that last one. After several years of a steady and often free fall decline that has squeezed industry profits and led to, prices rose last month.
At least that was the case in Europe, which imports many of its panels from China.
"The average selling price for Chinese crystalline silicon PV modules shipped to the European Union increased by 4 percent in March, the first monthly rise since January 2009," market research firm IHS iSuppli says in a press release. "Prices are set to rise by another 1 percent in April and by an average of 4 percent during the next three months."
IHS attributed the climb to "a number of factors" including booming demand in China and Japan, which helped eliminate oversupply. It also cited theagainst China. The EU has proposed tariffs on Chinese product but has not yet implemented them, as the U.S. has.
This could be a catch-22 for the solar industry. Vendors of solar gear might appreciate the potential relief to their balance sheets. But that relief might never come if consumers who are accustomed to falling prices decide that panels are now too expensive.
