Photovoltaic plants are an assembly of a number of photovoltaic modules grouped in rows, with the purpose to produce electrical energy, which through specific devices is transformed into alternating current with needed frequency and voltage, and as such is transmitted to the power distribution network.
Unlike isolated photovoltaic systems, plants do not require batteries for storing the produced electrical energy; it is immediately transformed and transmitted to the power distribution network.
Usually, such plants are constructed on the ground, attached to special carrying constructions, but it is also possible to be constructed on top of a roof.
There are several types of construction, differing mainly by the sun tracking axes:
- fixed mounted PV modules (fixed inclination angle without sun tracking)
- seasonal tilt adjustment (spring, summer, autumn, winter )
- single axis sun tracking (daily, weekly, monthly, quarterly, adjustment of the inclination angle of PV modules according to sun altitude)
- dual axis sun tracking:
- – real time sun tracking, using so called sun-tracker systems
- – by using defined position and trajectory of the sun for certain location
Each of the described construction types has its own pros and cons, mainly related to the construction cost, complexity, quantity of electrical energy produced, maintenance expenses, area needed for installation of the panels.
