The owner of the Farmers’ Market had a concern: when the sun comes out in summer, the room gets too warm because of the many windows.
We installed a solar-electric panel on the roof of the building, which uses solar energy to power a cooling fan. The air enters the room through the northern underground pipe. The speed of the airflow can be adjusted as needed.
The room stays cooler and the electricity bill does not increase because the solution is 100% solar powered.
