Photovoltaic Solar Energy

Photovoltaic (PV) Solar Energy is currently one of the leading renewable energies and it is growing and developing fast.
The photovoltaic effect consists in the transformation of incident light photons that reach semiconducting materials, into electric power.
There are basically two main types of applications:

  • Isolated PV Installations. Generally used in rural areas, countryside small buildings, relay masts, water pumping etc. where conventional grid does not reach and/or grid installation is not feasible. These installations do have specially designed power accumulators for PV use, as well as converters able to produce energy as a grid installation would do..
  • Grid connected PV installations. This type of installations works in parallel with the power grid. The installation produces power which is converted into AC by an inverter, prior to being exported to the grid.

The installation consists of four main elements:

  • A: PV solar panels.
  • B: Inverters.
  • C: Energy meters.
  • D: Power Grid.

ENERGÍA ERCAM has designed and developed a structural solution that gives a field of PV solar panels the capacity to track the position of the sun, consequently maximizing solar energy production everywhere in the world.


  • No fuel is needed, and it is silent.
  • Does not produce environmental pollution (a 5KW PV generator saves 5.000 kg. de CO2 in a year of production).
  • Life cycle longer than 20 years.
  • Resistant to extreme weather conditions: hail, wind, temperature and moisture.
  • Saves O&M costs for hard to access power grid areas.
  • Once installed, it has a zero energetic cost.
  • Easily adjustable, therefore installed power can be increased or decreased upon request.
