power in combinations with battery systems is now so cheap, simple and robust
that they are used for isolated micro-grid solutions, even in developing
countries. The cost of the produced electricity is however still costly, and
the electricity is therefore used for applications with high value / cost
ratios – typically lighting, when the sunlight has disappeared. This implies
that a significant part of the power generation during the daytime is stored in
the battery, and then used at times with no generation. Adding wind power to
the system may result in a better correlation between generation and needs, and
less needs for the battery.
project should compare solar+battery with solar+wind+battery solutions for
isolated micro-grid applications under different cost and operation conditions,
including investment costs, solar and wind resources, and load patterns.
Operation data from a 10 kW solar+battery (+wind) system in Kenya will be
made available for a case study.
