Solar Air Heater for Business or Home. You can’t beat free heat!

Posted By: Your Solar Link Team on February 13, 2010 in Solar News - Comments: 16 Comments »

Most heating systems consist of two stages – one that generates the heat and a second that delivers it (ie: a furnace burns oil to generate heat and a fan or circulating pump distributes that heat where it’s needed.)

With solar heating systems the sun generates the heat – for free!

Solar air heating systems use solar radiation to heat a particular room, using solar panels.
There are many ways to use solar heating of air, and one can also build a home with the help of online sources.

Check out the video below on home-made solar air heaters.

This is a type of solar thermal system, where air is heated in a collector from the sun’s radiation and transferred directly to the inner space or a storage medium, such as a can of rocks. Solar panels are used for the operation of such systems.

Solar panels heat the air which is then transported to a particular room. The basic components of this system include solar panels, solar collectors, a system of ducts and diffusers. The heated air can operate with or without a fan. Without the fan the air is distributed through the action of a natural ventilation system.

In agriculture, food products sometimes needs to be kept in warm places, especially during the monsoons. Solar air heating works well here. You can increase the temperature of the room so that it is properly heated. In this way the products may be safe and will not have spoiled due to moisture.

Solar air heating works much the same way as a factory solar hot water.
The heater is placed outside the room so it can capture the sunlight. It generally consists of solar panels, but people use a variety of solar collectors. Some use aluminum beverage cans and black paint. These are then placed on a suitable frame. The panels or holes in the cans should be connected so that the air travels through them. As cold air moves across the outside room via the cans, it is heated. Thus, hot air enters the destination room, causing the temperature to rise. In this way a solar air heater is a very economical way to heat a room. Instead of using heating devices that are expensive and require a lot of electricity, this method of passive temperature control is certainly an effective solution.

  3. The article is very interesting.
    As a 65 yr old woman living in Arizona, I plan on moving soon to a house that will require a new heating system. I would love to be able to use solar however I will not be able to afford solar panels.
    Would there be a more affordable alternative and where/who can I get it from? Any advise welcome

      Hi Linda,

      Thank you for your comments. Yes, solar panels are on the pricey side right now, but the technology is advancing rapidly, so costs should be going down in the more-near-than-distant future. If you need to power only part of your home, you may opt for just that many panels (average panel wattage is about 180-230 watts per panel, depending on manufacturer). Also, depending on your location, other renewable/green technologies may be more appropriate for your needs. Wind turbines, geothermal, solar and passive design are all ways in which we may achieve self-sufficiency while leaving less of a carbon footprint on the earth. If you have any further questions, please don’t hesitate to contact us at info@yoursolarlink.com and we will be glad to point you in the direction of a green and sustainable future.

      If you decide to proceed with using solar panels, we will be happy to guide you through this process and can supply you with solar panels and an inverter at a discounted price.

  5. Solar powered panels can either be mounted on the roof or your structure, or they can be installed as ground units. During the daylight hours, these panels will collect and store energy from the sun. After peak sunlight hours the stored energy will run the electricity for you business. If you need more electricity than what the panels can produce, it will come from the utility company. Solar powered electricity is a way to reduce your use of coal burning electrical power. Solar power is quiet, and it produces no waste by product.

  6. Solar Powered electricity continues to be used for industrial usages since the 1970’s, and it is in use nowadays much more than ever previously. For the reason that brand new united states government policies about clean coal come to pass, the price of your electricity will be anticipated to improve greatly. Numerous companies as well as private consumers are looking towards solar powered electricity in an effort to minimize expense.
