United Sun Systems is working with a new generation CSP Dish-Stirling System. This system utilizes the extremely high solar to electricity efficiency of the Dish-Stirling technology on combination with a number of notable developments and innovations, most notably:

A high temperature thermal battery for energy storage

A heat-pipe heat transfer system

A re-configurated solar concentrator

A gas hybrid system

The unique V4-90 high capacity Stirling heat engine

United Sun Systems was formed in 2010 with the ambition to supply the global market with the most optimal CSP Dish-Stirling solution. United Sun Systems bought the licenses to the best Stirling engine in the market, the V4-90 engine, and formed EUSDI (The European Stirling Dish Initiative), to meet the future demand of our technology on the European and North African market.

In the early 2012, United Sun Systems International and a Chinese/American company, in a joint venture, bought the largest CSP Dish-Stirling solar park ever built, the Maricopa solar park in Arizona. This purchase gave the new joint venture, United Sun Systems International Ltd, assets of 60 complete CSP Dish-Stirling units, test and performance data as well as a unique dish-receiver Alignment system.

United Sun Systems and its partners have been involved in the creation and development of more than 80% of all CSP Dish-Stirling projects since the 1970’s. USS is not together with among others, the US Department of Energy incorporating a Thermal Energy Storage solution, a Thermal Battery into the CSP-Dish-Stirling design

The Business model of United Sun Systems is to provide the global market with the most cost effective solar energy, lower price than PV in combination with batteries and 100% competitive to traditional fossil fuel, even without subsidies
