Solar energy offers many benefits that make it one of the most promising energy forms.
Renewable, non-polluting and available planet-wide, it contributes to sustainable development and job creation where it is installed.
Likewise, the simplicity of this technology makes it ideal for using in rural or difficultly accessed areas isolated from the network. An example is the rural region of Cajamarca in Peru, where ACCIONA has developed several projects to facilitate electrical self-sufficiency for inhabitants. Solar energy is also useful for generating electricity on a large scale and injecting it into the network, especially in regions where the meteorology provides for lots of hours of sun per year.
Solar capture modules are relatively easy to maintain, which, along with the continuing, sharp reduction in cost of photovoltaic cells, explains the present favorable outlook for solar technology. Solar plants also do not emit polluting gases and are silent.
Another advantage of energy borne from the Sun is its ability to generate local wealth, by lessening energy dependence on abroad. While it is certain that solar energy – like wind – is intermittent and directly depends on the weather and day-night cycles, rapid advances in electricity storage technologies are reducing this dependency and will lead to the increasing share of solar in the energy system.
