The SolarWall® system delivers the fastest solar payback on the planet by heating the ventilation air required in commercial and industrial buildings.

The solar air heating system is building integrated, and has been used globally for the past 20 years. Past customers include; FedEx, Ford, Wal-Mart, 3M, Bombardier, U.S. Military and NASA. SolarWall systems displace a significant amount of C02 and are eligible for various financial incentives.

SOLAR DUCT™

SolarDuct™ PV/T is a modular rooftop application of the PV/thermal technology. The heat is drawn off the back of the PV modules and is ducted to the nearest rooftop air handler. The ‘excess heat’ is then channeled into the building’s HVAC system where it is used to offset the heating load. The SolarWall® air heating panels serve as the racking system needed to mount the PV modules. This also contributes to the cost-effectiveness of the cogeneration system. The modular units are easy to install and are angled at an ideal orientation for maximum solar gain.

MORE INFORMATION ABOUT THE SOLAR WALL

REDUCE YOUR HEATING LOAD

Heating can typically be one of the largest energy expenditures in the building industry. The ability of a SolarWall® system to address this energy usage and to displace a sizable amount of it - and the resulting greenhouse gas emissions - explains why the technology has such a compelling return on investment. SolarWall systems produce up to 600 watts/m2 (60 watts/ft2) of thermal energy. When the sun warms the surface of the collector, the heated air is drawn through thousands of tiny perforations on the surface and ducted to the existing air intake. The solar heated air is then distributed throughout the building via the conventional ventilation system or dedicated fans and ducting.

EASILY INTEGRATED

The SolarWall technology is building integrated and has few moving parts. It has a 30+ year lifespan and requires no maintenance. Systems are available in a variety of colors and profiles to meet your building design requirements.

ABOUT PV SOLUTION

PV module efficiency is typically between 8-15%. What happens to the rest of the sun’s energy that shines on the panels? Most of it is converted into heat energy, which normally is lost and provides no value to the system owner. As well, the heat build-up behind PV modules reduces the electrical output by 0.4-0.5% for every 1°C above its rated output temperature (which is 25°C). Given that roofs can reach temperatures as high as 90°C, the actual operating efficiency of PV systems is often significantly less than the rated output.For standalone PV systems, high capital costs and low energy production result in very long paybacks. The PV/T cogeneration technology offers a solution that actually makes PV systems financially feasible in standard commercial, industrial, and institutional applications.

ABOUT CO2 REDUCTION

Considering the replacement of a natural gas installation, for a production of 2.1 GJ/m₂ a year, the CO₂ reduction will be around 150 kg/m₂ per year.

Better the sun irradiation is, higher is the efficiency of the solar wall and higher is the CO₂ emission reduction.
