SolarWall® productsuse the sun's power to lower energy costs, reduce greenhouse gas emissions and improve indoor air quality (freshness and evenness of temperature).

By the early 1990s, one of the world's most efficient ways to harness the sun's energy to help heat buildings of all shapes had been invented. The product's apt name:The SolarWall system. Worldwide interest was sparked immediately, and the ingenuity of the SolarWall® technology was recognized by organizations such as the U.S. Department of Energy, Natural Resources Canada, Popular Science Magazine, R&D Magazine, and several others.

The SolarWall technology has lead the way ever since, both scientifically and in global sales, with customers such as Ford Motor Company, GM, FedEx, 3M, Bombardier, the U.S. Military, and many more in 25 countries around the world.

The SolarWall® solar air heating system is a metal wall system that uses solar energy to heat and ventilate indoor spaces in new and retrofit application. Perforated collector panels are installed several inches from a south facing wall, creating an air cavity. (Southeast, southwest, east, and west wall are also possible.) The metal cladding is heated by the solar radiation from the sun, and ventilation fans located at the top of the wall create negative pressure in the air cavity, drawing in the solar heated air through the panel perforations.

A connection to an HVAC intake allows air to be preheated before entering the air handler, reducing the load on the conventional heater. This heated fresh air is then distributed into the building through the existing HVAC system or with separate air makeup fans and perforated ducting.
  • he SolarWall technology provides free heat for the life of the building
  • itreduces annual heating costs by $2 - $8 per square foot of collector, depending on the type and cost of fuel displaced
  • it delivers ventilation air that can represent up to 50% of a building's heating needs, and contributes 1.5-3.5 therms/ft2 (1.5-3.5 GJ/m2) of energy per year
  • it has anoperating efficiency of up to 75% (rated by both the Canadian and US governments)
  • on a sunny day, the temperature in the SolarWallcan raise the air temperature by 30Fto 76 F (16 C to 40 C) depending on flow rate
  • the SolarWall technology delivers annualCO2 savings of 1 ton for each 5 square meters of collector
  • thesolar cladding iscomparable to the cost of a brick wall, and the total installed cost after tax considerations and possible grants can make SolarWall panels less expensive than other metal or masonry walls
  • Even on cloudy days, the panelsprovides significant energy savings as a preheating system for ventilation air

Use of SolarWall®

Commercial buildings are well suited for solar air heating. ASHRAE guidelines specify certain requirements for ventilation air, and this can be preheated with a SolarWall systembefore entering the store, which cansizably lower heating costs.

Over the past 20 years, the SolarWall technology has become the most popular solar energy system for industrial buildings of all types. Most factories and other industrial complexes require a significant volume of fresh air to meet health and safety requirements. The SolarWall system is cost effective, and it also improves indoor air quality. As well, it can remedy many heat stratification issues that plague large buildings.

Military bases have proven to be especially good candidates for solar heating. Buildings such as warehouses, vehicle maintenance shops, hangars, and motor pools can benefit from the SolarWall technology because of the high volume of air flow required to provide ventilation andmaintain the indoor air quality.

Governments of all levels are the owners of buildings, and this affords them the opportunity to reduce energy costs within their jurisdiction and “lead by example” in terms of reducing CO2 emission. Suitable applications include; school, community centers, bus and vehicle maintenance garages, water and waste treatment plants, housing authorities, offices, and other municipal complexes.

Schools and community centers are ideal candidates for solar heating. ASHRAE states that each student requires a minimum of 15 cfm of fresh air, and it is costly to heat this large volume of ventilation air using conventional methods. Schools operate during the daytime when solar energy is available, making solar heating of fresh air one of the best applications.

Most jurisdictions require common areas and hallways in multi residential facilities to be continuously ventilated and pressurized to satisfy fire codes. Heating this air with conventional means is expensive, which is why many housing authorities are including SolarWall systems in both new and retrofit buildings. For older high rise buildings, if metal rain screens are required, the panelscan function both as a rain screen, and as a solar heater.

Solar Drying
The SolarWall panels can also be used to displace expensive fossil fuels in crop and process drying. They can function as the primary heater, or in a preheating capacity. Using solar heat for drying has become popular because it is especially well suited for delicate crops, and will not burn or harm produce, which may happen with steam heated or fossil-fuel heated air.
