A solar wall, also known as a Trombe wall, is a passive heating method that captures solar energy and stores it in a thermal mass, such as a brick or concrete wall. This energy is then gradually released into the room, providing supplemental heat during the day and night.
How it works:
Heat absorption: Sunlight shines through a glass surface, heating the air behind it.
Heat storage: The heat is then absorbed by a thermal mass (usually a brick or concrete wall) located behind the glass.
Heat release: As the temperature drops at night, the thermal mass slowly releases the stored heat, warming the room.
Steps to build a solar wall:
Choose the location: The solar wall should be placed on a house facade that receives as much direct sunlight as possible, preferably facing south.
Insulate the exterior wall: Make sure the exterior wall is well insulated to prevent heat loss.
Build the structure: Construct a wooden or metal frame to support the solar panel.
Install the solar panel: Cover the frame with a glass surface, such as insulating glass or plexiglass.
Add the thermal mass: Behind the glass, build a wall of brick, concrete, or other materials with a high heat storage capacity.
sure ventilation: Install adjustable openings at the top and bottom of the solar wall to control airflow and optimize system performance.
Materials needed:
Wood or metal for the structure, insulating glass or plexiglass, bricks or concrete for the thermal mass, thermal insulation, hardware, sealing materials.
