Solar Energy Essays

INTRODUCTION Solar energy, radiant light and heat from the sun, is harnessed using a range of ever-evolving technologies such as solar heating, solar photovoltaics, solar thermal electricity, solar architecture and artificial photosynthesis.[1][2] Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, …

Solar-powered water heaters use solar energy (sun’s energy) to heat water. There is no electricity required in the process even though it may be used to pump water to the tank or reservoir for subsequent use or heat storage. Solar-powered  water heaters  is a recent improvement in the technology of …
