Putting in Solar Powered Attic Fans are quick and easy and usually take about half an hour to build by yourself. This is especially true for photovoltaic lights, solar powered garden lights and solar powered battery chargers.

Putting in photo voltaic powered attic fans irresponsibly carries the potential risk of fire or filling your attic with carbon dioxide. Just be certain there's enough absorption openings to circumvent that potential threat.

Many producers now offer solar powered attic fans to ventilate attics as well as help keep attics cooler. Solar powered fans rely on a small (typically 10- or 20-watt) solar panel to power a DC motor if the sun is shining.

The fans, which usually exhaust air at a rate around 800 to 1200 cfm, are installed with intake vents (for example soffit and gable vents) to provide high-capacity powered ventilation without electric working costs.

Most vents usually are mounted high on the roof, nearby the... [more]

There's no question that energy costs have increased dramatically and are only going to continue to rise. Combined with concerns about greenhouse gases and the environmental damage that is resulting, more homeowners are looking to lower their carbon footprints and save money on energy costs. Heating and cooling are among the most costly home systems with respect to energy usage and now technology has introduced the solar attic fan, an inexpensive and sustainable way to reduce the energy required to keep homes comfortable year-round.

As most are aware, hot air rises over cool air. As the sun warms the roof and walls during the day, this radiant heat builds and becomes trapped in the attic. This trapped attic heat creates an additional load for air conditioning in the home to keep it comfortable. An unventilated attic also creates high moisture conditions that provide an ideal environment for mold, mildew, and bacterial growth that can damage the structure as well a become a... [more]

Many people have started using attic fans to vent and cool their homes. The use of such fans also saves money and precious dwindling resources. One type of attic fan that people have chosen to use is a solar panel fan. This fan runs off its own solar panels, which are installed on the roof of the home. But in order to work more efficiently one more piece is needed. That piece is a solar power controller.

A solar controller is a piece of equipment that runs between the solar panels and the fan. The fan has its own batteries to store up energy to run at night or when cloudy. But those batteries can be overcharged and burn out on days when it is very sunny. This can cause damage to the fan as well as a risk of greater damage done to a home. The solar power controller senses that the batteries are getting fully charged and then can shut off the charging process.
