Project:
Gather information about solar light , solar water heating system and solar cooker.
Please answer

Answer 1

Solar Light :
A solar light uses energy from the sun to produce light. (Solar light can also refer to natural light coming from the sun.) ... During the day, they use solar energy to charge a battery, and at night, or when it's too dark to charge the battery, the battery runs a light.

Solar water heating system :
Converts the Sun ‘s energy to heat water

A sun-facing collector heats a working fluid that passes into a storage system for later use. SWH are active (pumped) and passive (convection-driven). They use water only, or both water and a working fluid. They are heated directly or via light-concentrating mirrors. They operate independently or as hybrids with electric or gas heaters.[2] In large-scale installations, mirrors may concentrate sunlight into a smaller collector.

Solar cooker :
Takes the Sunlight to slowly cook the meal places in its chamber . The time used for cooking via solar cooker is double the time used by cooktops or electric induction
