Fotovoltaic Hybrid Electrification
Project of the comunity Cauchal
The comunity of Cauchal is sited in the Ecologic Reserve of Mangles Cayapas Mataje between San Lorenzo at the coast of Ecuador and Tumaco in Colombia.
The black population of Cauchal lives mainly of fishing. The average monthly family income is minor than 30 US $, from which they have to spend great part in transportation.
It is important that the comunity got its hibrid fotovoltaic solar system. They now are able to do their daily work at home and educate their children in the evenings and nights, and they´ve got access to radio- and television information.
The solar system helps to preserve the ecosystem of the mangles.
The comunity has got a microservice company which is collecting montly about 4 US$ from each family and is garantizing the sostainable service of electricalenergy in a long term.
The project was relaized by the comunity of Cauchal, CODESO and FEDARPOM S.L., the Federación de Artesanos Afro Ecuatorianos Recolectores de Productos del Manglar with its main office in San Lorenzo, Esmeraldas, Ecuador, Telefax 593-6-780533, firstname.lastname@example.org.
The main financing realized the Proyecto para el Desarrollo de los Pueblos Indígenas y Negros del Ecuador PRODEPINE RCN Telefax 593-6-727937, email@example.com. There should have been also some help of the local government the Ilustre Municipio de San Lorenzo.
It was planned to buy more fotovoltaic equipment, to get more service and to supply only solar energy to the coolers, but the problem is that the comunity owned mirco service company isn´t yet able to collect enough money, because the families haven´t got enough income to pay their cuotes.
Actually the comunity of Cauchal is trying to get their drinking water system, important for the families. They are looking forward to get help for a productive project to rise their social level.

The solar energy system consists initially of 57 panels Isofoton I 110 with a total of 6.270 Wp (Watts peak) which produces an daily energy average of 22,3 KWh. There are 33 staionary acumulators MAC with 12 V (volts) 150 Ah (Ampere hours), 8 regulators Isofoton I 30 A y 2 Inverters Triplite APS 3.600 W (generation of alternate current of 110 V AC for the local electric net) installed.
The system in Cauchal is hybrid, that means that there are two electric generators: one solar or fotovoltaic, which generates about 80 % of the daily energy needs and the other is an ordanary diesel generator, which supplies sometimes (when there isn´t sufficient sunshine) the rest of the energy (with high costs of diesel and mantainance). The comunity decided to run a hybrid system, because they depend on the ice for the fish comercialization. There was also a limit in financing the project.
During the day only the solar system is working and sometimes at night, in case that the stored energy in the acumulators has run out, the diesel generator is working for some time. The diesel is supplying directly to the net and at the same time recharging the battery bank. When the batteries are reloaded, the diesel gets off and the system works again out of battery.
