To ensure photovoltaic systems are able to compete with conventional fossil fuels, production costs of PV modules must be reduced and the efficiency of solar cells increased.

The equation used to calculate wind turbine power is: Power (W) = 0. 5 × ϱ × πr² × Cp × CF × v³ where ϱ is wind density in kg/m³, πr² is the swept area of the turbine, Cp is the power coefficient, CF is the capacity factor and v is the velocity of the wind in m/s.

Overall the manufacturing process of creating solar photovoltaics is simple in that it does not require the culmination of many complex or moving parts. Because of the solid-state nature of PV systems, they often have relatively long lifetimes, anywhere from 10 to 30 years. To increase the electrical output of a PV system, the manufacturer must simply add more photovoltaic components. Because of this, economies of scale are important for manufacturers as costs decrease with increasing output.

In this regard, hybrid mini-grids (solar energy + battery storage) have proven to be a viable and scalable solution. In IFC's opinion, successful cases in Brazil and Colombia reinforce the applicability of the model for similar conditions in Peru.
