Solar energy may not be as prominent as wind energy in Texas, having an installed capacity of 589 MW which puts Texas on tenth rank nationally. This can power 63000 homes. Nevertheless, growth of solar capacity was 65% in 2015 with a 48% increase of investment over that year. Installed solar PV system prices dropped 12% from 2015 and 66% from 2010.
In its Long Term System Assessment Update for 2016, ERCOT expects solar energy to grow from approximately 2% in 2017 to 17% in 2031. (ERCOT is the Electricity Reliability Council of Texas responsible for generation, transmission and frequency regulation in the electricity market of Texas).
