Workshop: PV off grid system for rural electrification in Indonesia

Our main goal in this project is to transfer knowledge to our partner so that lots of PV projects can be implemented in the near future through our partner independently.

Indonesia is a fast growing developing country, but today Indonesia still has around 13.000 villages
which are not yet electrified, because a lot of investment is needed to expand the power grid and also to
build new power plants. Even in villages with installed power infrastructure not all people can benefit
from it, because a lot of poor people can’t afford the cable connections to their houses or in many cases
not able to pay for the electricity bill. Some people are still using kerosene lamps and candles for lighting
purposes, which can be dangerous for user’s lungs (by frequent use in closed room). Furthermore,
lightings from candles and oil lamps are often not sufficient for some activities at home, so that more
problems such as decline of sight at early age can also be caused. A micro off grid Photovoltaic plant is
surely the best solution for this problem because it is clean, independent, flexible, and produces free


Our main goal in this project is to transfer knowledge to our partner so that lots of PV projects can be
implemented in the near future through our partner independently. In this occasion we are going to give
a small Photovoltaic Workshop for the tech. Staffs of Rumah Energi and also Staffs from some other
partner organizations. We will not only presenting the advantages of renewable energy and the
potential of solar power in Indonesia but also train them to design a simple off-grid solar power system.
At the end they will also receive a theoretical and practical training on electrical installation of PV-plant
and the safety issues. With this knowledge they should be able to design and install PV system for
simple appliances such as home lighting, water pump, agricultural machinery and many more.
Besides that, we have designed a standard model of PV-plant (from 50 to 200 W, indoor and outdoor
lighting) for our partner to use. The systems are in combination with efficient LED lamps and a sufficient
battery capacity, so that the plant can always produce energy even in bad weather (max. for around 4
rainy days, security of supply, no blackout). The standardized plant systems can be used allover
Indonesia and no complicated technical planning is needed. 3 sets of standardized PV-plant will be
installed in the training center, which can be used as training tools. We trust our Indonesian project
partner because they are known to have so many experiences on spreading and implementing the use
of renewable energy technology in rural areas (implementation of more than 20.000 micro biogas plants
in Indonesia).

We are happy to answer any questions and would be grateful for your support/donations!
