Where AC Supply Runs Short, Solar Attic Fans Can Fill The Gap

Spare parts are in short supply for air conditioning units. Keep your AC unit running longer with a solar attic fan.

For over 90 per cent of the world, there is no relief from extreme summer heat with air conditioning. Solar attic fans are uniquely positioned to bridge this cooling gap.

Currently, only eight per cent of the world’s population has regular access to air conditioning in their homes. Income inequality, especially in developing nations, continues to keep air conditioning out of reach for many. Even amongst those who can afford air conditioning, the local supply in some countries continues to lag far behind demand. Air conditioner rental businesses have sprung up to meet demand, but at times they too can run out of stock

Particularly in countries with extremely hot summers, interior cooling can literally mean the difference between life and death. Worse, the demand for air conditioning is expected to continue growing. Researchers estimate that about 70 per cent of the population in many countries will require air conditioning by 2050.

Solar attic fans like iSolar Solutions’ patented FLEX line of fans, are quickly proving to be a cost-effective retrofit to this growing global problem.


Studies have shown that the extra ventilation provided by solar attic fans can lower indoor temperatures by as much as 10C. They work by augmenting existing passive vents in homes. Passive vents are often enough to meet the minimum standards of building codes. However, they often fail to achieve adequate ventilation as they lack mechanical parts. When air isn’t circulating in a home’s roof, solar attic fans switch on automatically to give these passive vents a much-needed boost. 

Powered solely by the sun’s rays, solar attic fans can cool homes even in places where there is no connection to the local electrical grid. They add nothing to a home’s electricity costs. As a bonus, they produce zero emissions. 

Solar attic fans also help homeowners avoid hefty maintenance bills down the road. Compared to more mechanically complex air conditioning units, iSolar Solutions’ FLEX line of solar attic fans have fewer moving parts and require substantially less maintenance. These considerations are especially important given the ongoing spare parts shortage affecting the air conditioning sector.

Even for homes with air conditioning, a solar attic fan can cut down on the need for its use. They can trim electrical bills over the summer by as much as six per cent.


Because they lack complicated wiring, you can install a solar attic fan without an electrician in as little as 15 minutes. Most general contractors and roofers can handle the job of installing one in your home. The solar attic fans offered by iSolar Solutions fit into most existing vent holes. For added peace of mind, they come with a limited 20-year warranty. In addition, iSolar Solutions maintains a network of trusted installation partners who thoroughly understand the science of proper building ventilation.
