How efficient are thermo-solar Stirling generators compared to photovoltaic solar panels in terms of energy output, investment and surface needed to operate?
That's informative. Which one is more cost-effective in terms of investment?
The initial investment for thermo-solar Stirling generators is typically higher due to the complexity of the system, but their cost per kilowatt-hour is typically lower compared to photovoltaic solar panels over the long term.
