Project Solar Energy for "Ideas para el cambio" - UPDATE

Hello friends,

In the previous two years, I was working on a project of solar energy for self-consumption in a vulnerable zone of this country. The government just announce they'll change the Diesel generator of this community for a hydroelectric turbine.

Many ideas were exposed, since my PV system, Biogas solutions, wind turbines but, for this location, the most profitable solution was the Hydrogenerator. A part of San Juan river is providing the water they need and now, it will provide electrical energy.

Next, I expose some aspects what I think Photovoltaic was rejected for this project:

 1. The index kWh/kWp anually is about 1,034. Pretty low in comparison with cities in the caribbean coast which this index is about 1,600 kWh/kWp.
 2. My PV farm was design for provide about 80 kWh daily. With that index of generation, the size of the system was about 28kW and the area of coverage for this PV farms is about 218 m2. It is hard getting this amount of terrain without any obstacle.
 3. The systems would have about 50% of the total capacity in Battery storage. It means, the consumption of this energy should be in the peak hours of the sun but not always this is possible because the reliability of the sunlight. This increment the cost of the project tremendously. I though the idea for combining this two power sources, the river and sun power, in a hybrid PV- hydroturbine, but it requires more specialized equipment.

It was just a step, of many steps in renewable energy in this country. Many communities yet have not access to electrical energy, even in the most sunny towns. It is an opportunity for to change lifes and minds. My next project would be in a town in the North of Colombia. I am developing a smart battery based on Li-ion and an effective way to use in poor homes. I'll write in other time about this.

 Finally, I'm glad because the people now have clean energy. The river who calm their thirst now provide them energy.

How Deflt University of Technology changed my life through Delftx on EDX.org

Hi everyone!

Today I want to tell you how solar energy course changed many aspects of my life, and I mean not only academics, but also economic and environmental aspects.

It all started when I enrolled in a course MOOC of TU Delft offered on the platform EDX.org, called "ET3034TUx Solar Energy" which ended on December 6 last year.

I had not made ​​any progress related to the energy of the sun, but if I had studied about modern physics and that is currently the science that most like me. This previous knowledge of solid state physics helped me understand a little more the lessons of semiconductor related, although these topics were very clearly explained by Professor Arno Smets in each of its lectures.

Finally, the course culminated without committing any error in the exams and assignments so I got a score of 100% and a certificate of EDX of this course.

After gaining all this knowledge, install my own PV system using mathematical tools provided for that purpose, and economic results of the system were very satisfactory. Now, I have a saving of over 50% of money, a continuous electric fluid and a contribution to the reduction of greenhouse gases to the atmosphere.

Now, I would like to help the “Wounaan” indigenous community living in Colombia, specifically in the department of Chocó, in the city of "El litoral de San Juan" which are suffering from lack of electricity 18 hours a day or more, and derive their electricity of diesel electrical generators, which do not satisfy the needs of this population and to generate many pollution. The need is part of a national project called "Ideas para el cambio" (Ideas for the change) and it was expressed in the following website Ideas Para el cambio.

Some images related to the need:

I am currently waiting for a government response to the proposal to generate photovoltaic energy, it will take an investment of approx. € 40,000 and it would help 30 to 40 families.

Again, thanks to Delft University of Technology to offer this unique and free opportunity to all, thanks to Prof. Arno Smets and the whole team of Delftx and EDX.


I would also ask the team Delftx be selected to be one of the winners of a one-week workshop in Netherlands and expand my knowledge and continue to help poor communities in Colombia, who have no access to electricity.
