These solar-powered skylights open and close to allow fresh air inside. They have a built-in solar-powered fan that moves air in and out of the room. This is good because it helps the room stay cool. It also reduces the need to use air conditioning. Ventilated solar skylights improve the air quality of a room. This is important for rooms like kitchens and bathrooms that need to be aired out. These ventilated skylights have sensors that check the weather. They close automatically when it rains. This prevents water from coming inside and keeps the skylight safe.
Solar Tubes
These are also called tubular skylights. They are smaller than regular skylights and are used in places where space is limited. Solar tubes are good for lighting tight spaces like stairwells and small bathrooms. They capture light from the sun and spread it in the room through a reflective tube. Solar tubes are easy to install. They can be put in without having to change the roof.

When choosing a solar-powered skylight for a specific application, several factors should be considered. These are;
Consider the Type of Skylight
There are three main types of solar-powered skylights. Choose a type suitable for the intended application.
Solar-powered ventilating skylights are ideal for areas that need natural ventilation and daylighting. These include kitchens, bathrooms, and living rooms. On the other hand, solar-powered tubular skylights are suitable for areas with limited roof space or small rooms. They provide daylighting without requiring ventilation. Additionally, solar-powered fixed skylights are perfect for areas that need additional daylighting without ventilation needs. They are ideal for hallways and staircases.
Consider the Size and Placement
The size and placement of the skylight affect the amount of natural light and ventilation. Choose a size that is proportional to the room. Also, consider the placement to maximize natural light. For example, a skylight placed close to the roof ridge will provide more light than one placed lower down. Also, consider placing the skylight where the sun hits most, such as the south or west-facing roof.
Consider the Climate and Orientation
The climate and orientation of the building affect the performance of the solar-powered skylight. In warmer climates, choose skylights that open to provide ventilation and reduce heat. On the other hand, in colder climates, opt for fixed skylights that maximize heat. Additionally, consider the building's orientation. For instance, south-facing skylights capture more sun in the winter, while north-facing skylights provide consistent light throughout the year.
