Solar farms with solar tracking

 

In principle we will say that at present it could be said that a solar farm is a photovoltaic system installed on land or in water (lakes or sea), which has at least a thousand solar panels as a measure of size and production, that is, they occupy from one hectare and produce 500 Kilowatts onwards. This production, in most cases, has a single client, the administrators of the state or national electricity grid.

Also the concept of solar farm from the metaphorical point of view, is associated with a production farm that, unlike poultry farms that produce chickens or agricultural ones that produce vegetables, flowers, etc., photovoltaic farms produce watts, which It is the production unit of solar panels.

The average purchase of that watt produced in Europe or in the USA and Canada is around:

If they occur (here the measure is the kilowatt (kW), that is, every 1000 watts):

Between 15-30kW they buy the kilowatt at $0.110838/kWh (production per hour).

Between 30-50kW they buy the kilowatt at $0.110292/kWh

Between 50-100kW they buy the kilowatt at $0.109200/kWh.

For example, if we build a small solar farm of 500 kilowatts (that is, it produces 500,000 watts, in each hour of maximum solar irradiation), annually we should achieve (taking the price table shown as a reference) a profitability of at least 100,000 Dollars. A business, productive with more than 25 years of guaranteed earnings.

In solar farms, depending on the assembly used to install the solar panels, they can be farms with fixed structures or with tracking to the sun.

When solar panels use fixed structures, if we are in the northern hemisphere, they must face south and if we are in the south, the panels or modules must face north and thus manage to receive maximum solar irradiation during their peak hours, which normally They take place between 10:30 am and 2:30 pm.

When we use the solar tracking system, the panels and here it doesn't matter what hemisphere they are in, they are placed on a rotating axis that is oriented from north to south and the solar panels must initially face East, and then they move and end up looking west, following the path of the Sun.

This system achieves 25% more hours of maximum solar irradiation.

Then volunteers are heard...

Who dares to be a solar farmer?
