Israel-based energy company ZenithSolar has broken records with its 3rd generation CHP solar energy generator (Solar Z20) that combines heat and power systems to create an incredible 72% solar conversion efficiency. According to Ezri Tarazi at the Bezalel Academy of Art and Design and Head of Tarazi Studio, the generator has reached record levels by using a “semi-parabolic optical mirror for collecting solar energy” to power the local community’s electric and hot water use.

The difference between the new 3rd generation generators and the 2nd generation generators is that the new model is a combined heat and power, concentrated PV and solar thermal system. What this means is that not only does the system convert solar energy into electricity, it also converts any heat captured in the mirror collectors into electrical and thermal power.

The generators are installed in Kibbutz Yavne in Central Israel and provide hot water and power for the local community while also putting power back in to the back to the national grid. The system the most efficent in the world, and also produces the lowest cost per watt and best potential for energy system cost reduction as well as the highest efficiency in the field (+72%)
