Market Value of Thin Film in Solar Panels

Market Value of Thin Film in Solar Panels

Prices of thin film solar panels are decreasing each year compared to their crystalline counterpart. Avg. price of thin film panels are around $1.40.

Thin film panels are getting more efficient in converting light into energy.

Thin film solar panel production is much cheaper than crystalline solar panels.

Solar Market ExpansionSolar Market Expansion

“No. 1 solar energy country Germany will install 9.5GW worth of PV systems in 2011.”

“The United States will install the third largest total of PV systems in 2011, at 1.9GW, up 79.3% from 1.1GW in 2010.”
