Principle of Photovoltaic Power Generation System of Cape Verde Communication Base Station

Are there solar power plants in Cabo Verde?

Concerning solar power generation equipment in Cabo Verde, two mega solar power plants were constructed and went into operation in 2010 on Santiago Island and Sal Island respectively utilizing funds from the Government of Portugal. These plants have rated output of 4.28MW and 2.14MW respectively, making them smaller than wind power plants.

Should Cabo Verde use wind power instead of photovoltaics?

JICA Study Team recommends, instead of photovoltaics that will be relatively expensive, wind power as a renewable power source, since Cabo Verde has ample experience operating wind power, wind power offers both quality and quantity in conformity with the grid code, and output is relatively level and easy to utilize.

How much space do solar panels need in Cabo Verde?

In Japan, the necessary area for installation of mega solar equipment is said to be 10~15 m2 per kW. Since this takes the effects of shadows from adjacent solar panels into account, in Cabo Verde, which has a lower latitude than Japan, the optimum angle of solar panels is smaller than in Japan, which means that less area is needed for installation.

What voltage is used in Cabo Verde?

As for transmission & distribution system in Cabo Verde, 20kV is a standard voltage and 60kV is used only at Santiago Island, the capital of the country with the largest demand. 6kV or 10kV voltage distribution is still used in some region and it brings its operators difficulties with system operation and material and/or equipment procurement.

How is wind power assessed in Cabo Verde?

※Assessments of wind power and solar power are conducted inside the development zones designated by the Government of Cabo Verde. Particularly concerning wind power, which has been poorly assessed in parts, it is necessary to consider drastic revision of development standards, etc. including review of the zones.

What frequency is required in Cabo Verde?

Stipulated frequency in Cabo Verde is 50Hz±2Hz, and it is required for power sources not to be disconnected due to frequency fluctuations that arise on the system side.
