Is solar energy a cost-effective power generation system?
Solar thermal power, however, still has the advantage that it can store power. The technology differences are moot, however, since both solar technologies are currently much more expensive than other sources of renewable energy. Therefore, at present, solar energy is not a cost-effective power generation system. © Andrew Danowitz.
