===[[Solar Energy]]===

'''[[Solar photovoltaic (PV) systems]]''' use photovoltaic panels to convert sunlight directly into electricity. These panels can be installed on rooftops or ground-mounted, and the generated electricity can power household appliances, lighting, and heating systems. Excess electricity can be stored in [[battery systems]] or fed back into the grid through [[net metering]] arrangements.

'''Solar thermal systems''' capture the sun's heat to warm water or air for domestic use. [[Solar water heaters]] provide hot water for showers, washing, and other household needs, while [[solar air heaters]] can be used for space heating.

'''[[Passive solar design]]''' is an architectural approach that optimizes the use of natural sunlight for heating, cooling, and lighting. By incorporating features such as south-facing windows, thermal mass materials, and shading devices, passive solar design can significantly reduce a home's energy requirements.
