“Design is not just what it looks like and feels like. Design is how it works.” –Steve Jobs

The math is the math is the math. There is only a finite amount of sunlight and infrared rays available for solar companies to collect.  A collector's efficiency is equally as important as its cost. When a collector has the highest efficiency and the lowest cost of all other solar devices, it can be stated that it is, "the most cost-effective solar collector available". Sunreps' collectors meet this criteria.

Sunreps is a Redmond based company. Western Washington's sunlight is some of the worst in the country. Seattle in a good year gets 2 therms per sq ft of heat throughout Seattle's heating season. In bad solar years it's closer to 1.50 therms per sq ft. Natural gas prices have hovered around a $1.00 a therm for years. So on average a non-glazed solar space heating collector produces about $1.85 per sq. ft. if facing south.

Sunreps' new fabric collector is now a cost-effective renewable energy solution in the commercial building sector where previously no reasonable solution was available. Sunreps collectors represent a new technology for an old problem.

Sunreps metal solar space heating competition installed on the south wall of a commercial building typically run between $30-$40 a sq. ft.installed  and their rooftop application runs between $60-$80 a sq. ft. installed.  A simple payback for a metal collector ranges between 20-27 years for a south wall installation, without incentives. The solar math for PVs in the Northwest is equally challenging as the chart below demonstrates. Even with Sunreps most expensive installation, the Rooftop Collector (RT), the math still highly favors Sunreps.
