eSolar is a US based Solar Thermal Technology Startup which has managed to raise $182 million from top VCs and investors and managed to win contracts to build solar power plants using its properietary Power Tower Technology in the US,China and India.Note like Brightsource Energy,eSolar is one of the most promising CSP startups which has managed to get funding and contracts,it now needs to execute to deliver on its potential.
Solar is using the Power Tower Technology same as Brightsource Technology which differs from the parabolic trough mainstream CSP Technology.Note Parabolic Trough Technology is used by most of the established Spanish players like Abengoa.It is also the Technology used in the 392 MW largest solar thermal plant in the US built in the 1980s by Luz.In this technology thousands of heliostats (mirrors) reflect the solar light onto a “Power Tower” where water or salt is heated up.This heat energy is then transferred into Electrical Energy through standard Steam Turbines and Generators used in Gas,Nuclear and Thermal Power Plants.
