Aora’s solar tulips start shining in Ethiopia, without water!


Investments in solar energy innovations are not dead! Remember those weird and wonderful solar energy harvesting tulips planted in Israel and Spain? Seen miles away the sky-high tulips have found a new commercial home – in Ethiopia, the company announced last week in a press statement.


We’ve covered Aora over the years and thought possibly that this CSP, or concentrated solar thermal power innovation didn’t grow. We were wrong.

The Ethiopian Government, looking for resilient off-grid systems, is now piloting Aora’s system for sustainable development.

Aora’s tulips collect solar energy from 50 small mirrors and then focus the energy to heat oil and air, creating pressure to drive turbines in the tulips. The turbines create electricity. The solution runs without steam and water, important for off grid locations where there is no water.

We all may know that Ethiopia has grand ambitions to grow its economy fast and is creating the Renaissance Dam to hold back water from Egypt’s Nile to create hydro power. But even when this goes online, getting the power to the people through the grid can take 20 years or more.

This is where Aora’s solution may help:

Rural communities and villages in Ethiopia, and all over Africa for that matter, have not been able to develop themselves due to inefficient access to electricity. This affects the daily lives of people, from needing power to run schools, hospitals, and industry, to providing refrigeration for food processing and post-harvest storage.

We see solar power solutions for Africa out there already like Nova Lumos which has a novel business model to provide solar power for phones and limited residential use (individual units). Where people are poor and not able to invest in the one time fee, Nova Lumos lets people pay in increments – for the energy and system through the phone. Read here about how Nova Lumos from Israel puts power pimps out of business in Africa.

Aora however operates on the community or village level, giving electricity even during cloud cover or rainy days where the unit switches seamlessly to biofuels.

Unlike huge CSP systems (think Brightsource – also from Israel) Aora needs less than acre, or  3,500 square meters per module. Each module can provide 100kWh of solar electricity as well as 170kW of thermal power. The system’s heliostats follow the sun.

Built to be off grid the Aora system doesn’t require intensive investment to hook it up to the energy grid, nor does it require expensive energy storage operations since it can be hybrid and run on alternative power when the sun doesn’t shine.

The Aora systems are modular and farms of Aora tulips can be connected to generate larger amounts of power, together.

How Aora solar energy works in residential areas. So pretty!
