Easy Ways to Save Using Solar Energy

Summertime has arrived in New Jersey, and energy costs are on the rise. Running the air conditioner makes many people cringe, as it drives up energy consumption and bills. For those not yet able to make the full leap to completely solar driven power usage, solar attic fans can help decrease the level of energy needed to keep your home cool.

Solar Attic Fans

Solar attic fans can decrease the cooling load on your air conditioner. They increase fresh air circulation, keeping your roof and attic space cooler and extending the life of your roof. They come on when the sun is out and heating up your roof and attic, so they only work when needed to cool down the worst of the hot air.

Two fan options are generally available with adjustable solar panels. The 10 watt ventilates 1200 sq feet and the 20 watt covers 1800 sq feet. Installation costs range between $475 to $600, and most fans will pay for themselves in just a few years by reducing energy needs and prolonging the lifetime of most roofs.

Solar Tube Lighting

Solar tube lighting can be a tremendous money saver at any time of year, bringing natural lighting into your home or business. Installed lights range from approximately $350 to $600. The expense is worth it, as they will pay for themselves over time by reducing costs from electricity and standard light bulb purchases. The highly reflective light pipes can be up to 18-20 feet long, and are made of high grade aluminum with seamless construction.

Tubular skylights are smaller than most other skylights. They have roof-mounted solar collectors, which increase their daylighting potential even with their small size. Since a rooftop solar collector has such a small surface area, tubular skylights minimize heat loss in the winter and heat gain in summer.

The diameter of the tube determines the coverage area. A 10 inch solar light will cover up to 150 sq feet, and provide the equivalent of up to 300 watts. A 13 inch tube has a coverage of 300 sq feet, with about 500 watts. A 21 inch light covers 700 sq feet and delivers up to 1450 watts.

Both of these options can help you keep energy costs down. Contact Arosa Solar and talk to an expert about how you can save money by using the clean, renewable energy of the sun.

    Solar attic fans are not only the least expensive (in terms of total cost of ownership, which is purchase price + operating costs), they are also the most environmentally friendly way to ventilate an attic. Unlike conventional electric attic fans, solar attic fans don’t use any electricity from the power grid at all! I have really been trying to get the word out about this method of attic ventilation at Solar Attic Fan Info because I think not enough people are aware of the benefits – please check it out!
