Frequent questions

Why solar self-consumption?

Mainly because the customer saves on his electricity bill.The price of energy in the market does not influence solar energy prices. The customer generates his own electricity. Giving greater value to the property with a self-consumption generation installation. It has tax advantages as it is a cost and can deduct the corresponding part of the corporate tax. For environmental awareness.

Is self-consumption legal in Spain?

Yes, generation installations connected to an internal grid are currently legal. Customers can be treated as consumers: those who have an installation that does not feed into the grid; or as consumers and producers: those who have an installation that feeds the surplus into the grid.

How does a photovoltaic panel work?

Basically, without going into too many technical concepts, a photovoltaic panel is made up of a series of several solar cells which, on receiving solar radiation, each of them generates a voltage and current depending on the level of radiation (the more sunlight, the greater the generation) and this generated electrical energy is what can be used at the output of the solar panel to power electrical equipment.

What types of solar panels are there?

In summary, we can find thermal solar panels (to heat water) and photovoltaic solar panels (to generate electricity). Within this second type, the photovoltaic ones, we can generally have mono-crystalline and poly-crystalline types.

What is a photovoltaic panel?

A photovoltaic plate consists of a set of photovoltaic cells that generate electricity from the sunlight that strikes them by means of the so-called “photoelectric effect”.

What is the nominal power of a solar panel?

Like any electrical device, a solar panel has a nominal power and a real power. The nominal power is the one that it has according to its data sheet, and the real power is the one that it can actually produce. For example, a solar panel with a nominal power of 300W according to its data sheet may actually have 305W. That is why the data sheets also usually talk about “positive tolerance”, which is the % more power that a solar panel can have over its nominal power.
