Go Greener Tips

When it comes to energy usage these days lots of people are searching for alternative vitality sources and as such photo voltaic power is very much coming into vogue. At its current level of technological evolution, solar power is a helpful means of powering small engines to run simple devices. Fans are one such easy device and you will many instances where using a solar powered fan makes more sense than a fan powered by typical means.

Many manufacturers now supply solar powered attic fans to ventilate and help keep attics cooler. If there’s inadequate ventilation in the attic and poor sealing between the attic and the other rooms in the house, attic followers powered by electrical means can probably draw air from the home into the attic. Not only does this compromise energy effectivity but it will probably also increase the risk of moisture problems in the attic.

Solar powered fans rely on a small photo voltaic panel (typically 10 or 20 watt) to power a DC motor when the sun is shining. The followers are installed with consumption vents to provide high-capacity powered ventilation without electric operating costs. Most vents are mounted high on the roof near the ridge and are mixed with soffit or gable vents for balanced intake and exhaust air streams. Ventilation is just provided when there’s ample sunshine to power the fan motor. The highest fan speed will are inclined to coincide with the best heat from the solar and consequently the greatest need for attic ventilation. By decreasing attic temperature, attic fans might help reduce summertime cooling masses while on the same time providing ventilation without the added utility load.

Using solar power to power air vents in your attic means you eliminate the necessity for electrical wiring in this a part of the home and as a photo voltaic ventilator uses no electricity you’re also avoiding any ongoing operating costs. You will discover that the equipment prices for a solar powered attic fan are higher than those of a conventionally powered fan (around $200 more) but this will often be offset by the money you save in not having to increase electrical wiring into the attic. In addition to attics additionally, you will find photo voltaic powered fans used in greenhouses, outhouses, garages, sheds, out-buildings, and paint rooms.
Retail prices for solar powered attic fans vary from about $350 to $600 depending on ventilation capacity, the manufacturer, and optional features such as a thermostat.

In instances of new construction, roofers will often install powered ventilating units. If these models are photo voltaic powered roof vents there might be no want for an electrician to tough and finish wire the units. For retrofit projects, a roofer or do-it-yourselfer will be able to install a solar-powered attic fan using standard tools and techniques.

Whilst not applicable in each instance where cooling is required, solar powered attic followers are an example of sensible thinking using a natural vitality source.
