Our Technology Advantage

At the heart of the integrated energy solutions from Net Zero Impact LLC are the patented and proven Thermomax solar-thermal tubes manufactured by Kingspan Solar.

Solar thermal technology transforms direct and diffuse solar radiation into useful heat using a solar collector. Each solar collector consists of a highly insulated manifold and a row of solar tubes. The vacuum inside each tube (pressure <1 x 10-6 mbar) provides perfect insulation, protecting the system from outside influences such as cold and windy weather or high humidity.

The solar tube's vacuum technology also ensures the most efficient collection and effective transfer of sunlight energy into heat. This technology provides proven, long-lasting, superior performance, up to 10 times more efficient than competitive solar technologies.

The Kingspan Solar range of green-energy products reflects our ongoing commitment to a zero carbon lifestyle and a brighter future for all of us.

The advantages of Thermomax products and integrated Net Zero Impact systems include:

  • Designed specifically for Pacific Northwest climates.
  • Supply up to 80% of annual domestic, hot water needs.
  • Work from dawn until dusk, throughout the year.
  • Provide heat even in cold, windy or humid conditions.
  • Rapidly conduct and transfer radiant energy into heat.
  • Are 30% more effective than flat plate collectors.

Solar Thermal Collectors vs. Solar Cell Technology

For the Pacific Northwest environment, solar-thermal technology is ideally suited to meet the renewable energy needs and return-on-investment (ROI) requirements businesses seek.

The bottom-line benefits of solar-technology are impressive. While the most optimistic solar-cell installations estimate that a positive ROI may be achieved in 15 years, integrated solar collector systems from Net Zero Impact LLC can deliver positive return in as little as 3 years.

The key benefit of solar-thermal technology versus solar cells is efficiency. Solar-cell systems generate electricity directly from the sun's rays, while solar-thermal systems generate hot water. Tests demonstrate that solar collector technology is significantly more efficient:

  • Solar cells produce electricity at up to 20% efficiency,
  • Solar-thermal collectors produce hot water at up to 80% efficiency.

Solar-cell technology is dependent upon ample sunlight for the efficient transformation of sunlight to energy. Solar collector technology, on the other hand, is capable of transforming diffuse light into hot water, ideal for the overcast conditions typical in the Pacific Northwest. Of course, the more sun the better in terms of efficiency gains, but solar-collector tubes are uniquely suited for less-than-optimal sunshine environments.

Collector efficiency is defined as the percentage of sunlight energy striking the collector that is converted into hot water. This hot water can be used for radiant heat, used with forced-air heating systems, or even as a direct heat source for industries requiring hot water (note: the Net Zero Impact solution is a "closed system" meaning the heated liquid never leaves the system, but transfers its heat to other liquids, including water, through high-efficiency heat exchangers).
