How to install solar panels to reduce your home electricity bill?

  • Subsidies of up to 55% for solar installations.
  • Compensation of energy surpluses guarantees additional savings.
  • Virtual battery optimizes the use of your surplus in winter.

Installing solar panels at home

A few years ago, the renewable energy Solar panels were once seen as a technology of the future, but today, self-consumption based on solar energy is an increasingly accessible reality. Thanks to this advancement, it is possible to produce electricity directly in our home and use it to significantly reduce our monthly electricity bill. Let's explore everything that installing solar panels at home entails, its many advantages and how you can further optimize energy savings through this system.

Installing solar panels in your home: a profitable investment

Installation of solar panels

Opt for self-consumption through the installation of solar panels at home is a great way to generate and control your own electricity. In fact, by being connected to the electricity grid, you have the ability to acquire the energy needed to cover any production shortfall, while being able to sell any excess energy you do not use.

The profitability of a photovoltaic installation is increased by several factors, such as the available subsidies, the drastic reduction in the cost of solar panels, as well as the possibility of offsetting or selling energy surpluses through the electricity grid. The latter is key to maximizing profits, since, depending on the size of the installation and the location, you can achieve a significant reduction in your electricity bill.

Furthermore, solar energy is particularly effective in regions with many hours of sunshine per year, making Spain a particularly favourable place to take advantage of this clean energy. Households that opt ​​for solar panels not only save on their monthly bill, they also contribute to fighting climate change by reducing their CO2 emissions.

Key advantages of photovoltaic installation

Let's look at some of the key advantages of this system:

  • Savings on the electricity bill: Installing solar panels can reduce your electricity bill by more than 50%. As you generate your own electricity, you are less dependent on the grid.
  • 100% renewable energy: You are harnessing the sun's energy, a completely clean and inexhaustible source, which reduces your carbon footprint.
  • Subsidies and tax benefits: Depending on your location, you may be eligible for grants that cover part of the installation costs, up to 55% of the initial investment.
  • Controlling your energy: You can monitor your production and consumption in real time, which gives you absolute control over your energy expenditure and allows you to further optimize your consumption.
  • virtual drums: Thanks to the virtual battery, you can accumulate your energy surpluses and use them later to compensate 100% of your consumption during the months of lower production.

What is virtual drum?

La virtual battery This is one of the most interesting features of modern self-consumption. Essentially, it is a virtual piggy bank where the surplus energy you generate but do not consume is accumulated. This surplus is translated into euros, which are used to offset the value of your next electricity bills, ensuring that you can achieve up to 100% savings on your electricity consumption.

Thanks to the virtual battery, you not only optimize the use of the energy you generate, but it also allows you to better manage the peaks and valleys of energy production and consumption throughout the year. During the months of lower solar production, such as winter, you can use this virtual battery to continue saving on your electricity bill.

The implementation of the virtual battery is especially useful in situations where you do not have the space or capacity to install physical accumulators, which translates into an economical and efficient solution for homes looking to maximize savings. In addition, thanks to its flexibility, you can adjust its operation according to your electrical needs, always ensuring that your surpluses are used in the best possible way.

Design and installation: key steps offered by Factorenergía

If you are considering taking the step towards photovoltaic self-consumption, companies such as Energy factor They accompany you throughout the entire process to make the transition as easy as possible. From the initial design to the management of energy surpluses, these companies take care of all technical and administrative aspects.

The process that a solar panel installation company normally follows consists of the following steps:

  • Initial study: An in-depth analysis of the characteristics of your home is carried out, including orientation, available roof space and consumption needs, in order to design an initial proposal.
  • Final design: Once the initial proposal has been accepted, the technical and structural details are precisely defined for a final proposal.
  • Materials and installation: After signing the contract, the solar panels are installed, taking care of all the technical details and leaving the installation ready to start generating energy from day one.
  • Legalization and management of surpluses: The company also takes care of all legal procedures, including subsidies and the sale of surpluses to further offset your electricity bill.

Maximize savings with surplus compensation

One of the most effective ways to save with solar panels is by taking advantage of the surplus compensationThis system allows any unconsumed energy to be poured back into the grid, and in exchange, you receive financial compensation that is automatically deducted from your electricity bill.

This model is regulated by Royal Decree on Self-Consumption 244/2019, which establishes that any energy generated by your photovoltaic installation that exceeds your consumption can be reinjected into the grid. In exchange, you will receive financial compensation for these surpluses, which constitutes an important source of additional savings.

Although the offset price is not as high as the cost of the electricity you buy, it still represents a significant saving, in addition to optimizing the use of the energy you produce. It is an excellent opportunity for those homes that have an oversized system or that cannot consume all the energy they generate during peak hours of the day.

In the case of grid-connected photovoltaic installations, surplus compensation is key to further reducing your electricity bill, since this type of compensation only applies to the value of the energy that you have not personally consumed.

Subsidies for the installation of solar panels

Currently, in Spain it is possible to access subsidies of up to 55% of the total cost of a photovoltaic installation thanks to the European Next Generation funds. These subsidies are designed to reduce the initial cost and make the transition to energy self-consumption more accessible.

In addition to the European funds, many autonomous communities also offer tax deductions, property tax reductions and other tax benefits, which together can considerably reduce the initial cost of installing solar panels. Some regions even offer additional aid for self-consumption, with additional incentives for renewable energy projects in rural or depopulated areas.

Depending on your location, you can also access loans on favourable terms through different banking entities interested in promoting this type of sustainable installation. These loans, in combination with subsidies, allow the installation of solar panels to be paid off in a shorter time, increasing its profitability.

Self-consumption in homes: how much can you save?

The exact savings that can be obtained with a solar panel installation depends on several factors such as:

  • Installation size
  • The orientation and geographic location of the home (areas with more hours of sunshine can generate more energy)
  • Average electricity consumption at home

According to IDAE data (Institute for Energy Diversification and Savings), a solar photovoltaic installation in an average home can save between 40% and 60% on the electricity bill. This saving can be increased if you have batteries that store excess energy, or if you take full advantage of the compensation for surplus mentioned above.

In addition, owners who opt for self-consumption can benefit from a return on investment in a period of 3 to 5 years, making this technology a profitable investment in both the short and long term.

Installing solar panels therefore not only means savings, but also energy freedom and sustainability. In a context of constantly rising energy costs, generating your own electricity is also an opportunity for energy independence, minimising your dependence on traditional electricity companies, while contributing to the creation of a more sustainable and clean energy system.
