Production levels for 2020 and 2030 are 50,000 and 60,000 modules per year, respectively. No major advances beyond the introduction of heat pipes in the 2010 time frame are assumed for 2020-2030. However, evolutionary improvements in mirror, receiver, and/or engine designs have been assumed. This is a reasonable assumption for a $2 billio n/year, dish/engine industry, especially one leveraged by a larger automotive industry. The system costs ar e therefore 20 to 25% less than projected by MDA and SAIC at the assumed production levels. The MDA and SAI C estimates are for their current designs and do not include the benefits of a heat-pipe receiver. In addition, the MD A engine costs are for an engine that is being manufactured primarily for solar applications. Advanced concepts (e.g. , volumetric Stirling receivers) and/or materials, which could improve annual efficiency by an additional 10%, have not been included in the cost projections. With these improvements installed costs of less than $1,000/kW e are not unrealistic.

Solar Stirling Engine Basics Explained

The solar Stirling engine is progressively becoming a viable alternative to solar panels for its higher efficiency. Stirling engines might be the best way to harvest the power provided by the sun. This is an easy-to-understand explanation of how Stirling engines work, the different types, and why they are more efficient than steam engines.
