What is the purpose of a solar battery model in Colombia?

The objective of the model is to derive the cost-optimal size of battery installments depending on local temperature, solar radiation data, and regulatory conditions, such as net-metering and electricity prices. Detailed information on the data used to model Colombia can be found in the appendix.

Which energy source is most expensive in Colombia?

Coal, Colombia’s other dominating energy source besides hydro-power, on the other hand, becomes one of the most expensive ones, once all its negative effects (e.g. air, water and soil pollution, GHG emissions, etc.) are taken into account [ 60 ].

How much does solar energy cost without storage?

The current retail price is around 0.50 €/kWh [ 65] and three times higher compared to the other examined regions. Consequently, the IRR are a lot higher reaching 40.75% at a PV size of 1.5 kW p without storage, as shown in Fig. 8 a. Similar to the scenario above, the most profitable combinations do not include storage.
