Is decentralised solar power a cost-effective way to power Madagascar?

A costly expansion of the national electricity grid is a long way off and not the most cost-effective way either. Madagascar is one of the sunniest countries in the world with more than 3,000 hours of sunshine per year, so decentralised solar power supply to rural areas is not only easier but also cheaper.

What is a solar tracking system?

A solar panel precisely perpendicular to the sun produces more power than one not aligned. The main application of solar tracking system is to position solar photovoltaic (PV) panels towards the Sun. Most commonly they are used with mirrors to redirect sunlight on the panels.

How much does a solar tracking system cost?

If you opt for a single-axis tracking system on the same array, the total cost would increase to about $20,000. This represents a 57% premium over the fixed array cost for only a 35% increase in solar output. A dual-axis tracking system would be even more expensive, totaling around $26,000.

Does Madagascar have a power supply at night?

Lithium-ion batteries also provide power at night. Madagascar is the largest island state in Africa and the fourth largest island in the world. With the equivalent of 440 US dollars a year 1, the annual gross national income per capita is far below the average of the other African states south of the Sahara.

What are the applications of solar tracking system?

The main application of solar tracking system is to position solar photovoltaic (PV) panels towards the Sun. Most commonly they are used with mirrors to redirect sunlight on the panels. Cross-Reference: Design and Implementation of High Efficiency Tracking System

How do solar trackers work?

Based on how they work, their motion/flexibility, and type of tracker they are classified as follows: Passive tracking devices use natural heat from the sun to move panels. Timed trackers use a set schedule to adjust the panels for the best sunlight at different times of the day.
