There are different solar technologies already available: Solar photovoltaic panels in a wide variety of solar cells to produce electricity, Solar collectors to produce warm water, heating and cooling as well as Concentrating Solar Power (CSR) with dish engines, power towers and CSP linear concentrators. Through further research & development all these technologies could be improved and enhanced. The sunlight radiating to earth is more tan enough to satisfy all our energy needs sustainably.
