The profitability of photovoltaic self-consumption exposed

Currently it is very common to see news related to self-consumption and the impressive savings that solar energy systems are achieving in homes, but to what extent is this true and what share of fiction does this statement imply? Everything is a question of profitability and of course the necessary initial investment, so this post will definitely clarify all these questions and the advantages of photovoltaic self-consumption will be exposed.

The analysis of the energy consumption of our homes is a fundamental issue due to the high prices of electrical energy and the various problems in obtaining the fuels to generate it. The energy certificate is capable of indicating the consumption of the property in order to make timely decisions, but it is only one variable of the many to know in order to enjoy know in detail the real profitability of self-consumption relative to solar energy.

Solar panels, self-consumption and profitability

The production of electrical energy through renewables is a valid possibility to reduce the electricity bill, and solar energy through self-consumption is the most widespread option due to various factors influential such as its versatility, the ease of installation in homes and the adaptability of photovoltaic panels. The same ones that allow you to meet the electrical needs of a house and also sell the surplus, if any.

The economic advantages of photovoltaic self-consumption

Self-consumption through solar panels is one of the renewable energies with the greatest respect for the environment, as well as being clean and cheap. Hence savings in gas and electricity rates are broadly substantial and in many cases even totally dispensing with external supply networks.

Solar energy installations also allow you to add extra value to your homethis increase in value can usually increase the value by 4 or 5%.

Real possibility of self-sufficiency but also of commercialize with the excess energy in case of obtaining surpluses. This is generally possible in places where there are many hours of usable sunlight per day and produce more electricity than you need.

Subsidized compensation is the most common way to achieve great profitability with self-consumptionhere the consumption of the power contracted with the electric power company and the energy consumption of the house are compared, obtaining the discount of what is saved through the electricity discharged.

Necessary elements to enjoy self-consumption

The installation of solar panels obviously requires certain elements that are classified as a initial investment to install your solar panels and thus take advantage of self-consumptionto achieve this you must have at least these four elements:

tariffs save photovoltaic energy

  • solar panels: They carry out the functions of receivers of solar radiation that will be converted into electrical energy. The greater the amount of surface, there will be a greater capacity to absorb solar energy and therefore greater production of electrical energy with a higher final savings rate.
  • solar batteries: Necessary for store energy that is not consumed immediately and thus manage to save it for when it is required (night hours, when the absence of solar radiation is absolute).
  • solar inverter: Indispensable to convert and adapt electrical energy to the various conditions of homes.
  • digital counter: In charge of keeping the precise control of the electrical energy generated and transmitted.

The initial investment of a solar energy system

The initial investment for solar panels could be established as a significant outlay, but it is balanced immediately thanks to its high durability over time to achieve a timely and safe amortization of the expense. In addition to savings on gas and electric rates, which can reach and exceed 50% of billsdepending on the hours of sunshine to which the house is exposed.

A practical example could be an initial investment of about 5 thousand euros, through which it is possible to generate between 4 or 5 kilowatts, an amount sufficient to meet the needs of an average home. Additionally, there are many subsidies related to the installation of solar energy for the vast majority of Spanish communities, as well as a multitude of tax benefits for all those homes that implement solar panels as an energy solution.
