How to Build Your Own Solar Air Conditioner

What You'll Need
Plastic tubing
Copper tubing
Cable ties
Circulation pump
Cooling fan
Solar panel
Evaporative cooler
Spade or shovel

 Using a solar air conditioner  is a convenient way of saving energy cost. Approximately 20 percent of all electricity in USA is used by air conditioning units. It is possible to make one that uses solar panel which is an inexpensive and efficient source of power.

Step 1 – Get Necessary Materials

Buy materials to be used for building a solar air conditioner in a hardware store that specializes in solar products. Other tools and equipment can be obtained from rentals.

Step 2 – Build Ground Source Cool Fan

Inspect the ground outside the house and locate aposition to dig a location for the source cool fan. Decide where to position the air cooling conditioner in the house too; this makes it possible to locate the point which the cooling fan will be connected to the rest of the equipment in the house. It can be through a wall or a window. Make sure it is as close to the house as possible and avoid interfering with the foundation.

Use a spade or shovel to dig at least two meters into the ground.

Step 3 – Position Plastic Tubing

Obtain the coil of plastic tubing and bury it below the ground. This provides consistent average temperature of around 11.5 degrees Celsius all year round. Make sure it is well covered.

Step 4 – Connect the Tubing

Locate the best position to connect the plastic tubing to the rest of the house. Drill a hole through ventilation block or use some space through the window. Pass the tubing through the opening and connect it to the fan located in the house.

Step 5 – Prepare the Fan

Wrap the copper tubing around the back of the fan in a spiral; secure it to the grills using cable ties. Obtain anti-freeze which is to be pumped around the system. It acts as a coolant and does not freeze during winter. 

Step 6 – Install Solar Panel

Locate the best place to mount the solar panel and attach it to the roof. Secure it with stainless steel lags provided in the installation kit. Connect a power inverter and storage battery.

Step 7 – Install Circulation Pump

Install a circulation pump at the a few inches away from where the plastic and copper tubing are joined. Make sure it is secure and connect it to the solar power batter for it to start working.


Make sure to buy a circulation pump that has low power consumption. A 12 V unit can work effectively.
