Solar self-consumption
Switch to solar panels, use solar for own power!
Self-consumption of electricity with solar panels consists of generating and consuming the energy produced by your photovoltaic system. Due to the advantages provided by this method, more and more homes are opting for self-consumption from renewable sources instead of relying solely on the conventional electricity grid.
Producing your own energy at home allows you to save significantly on your electricity bill reducing it by up to 70%, but it also provides you with more energy independence.
Energy independence aims to reduce consumption of fossil fuels, using renewable and unlimited resources such as solar to generate the energy we consume in a more sustainable way and reduce the carbon footprint on our planet. It will avoid the worries caused by the constant fluctuations in electricity prices of the large electricity companies.

Discover the advantages of opting for self-consumption photovoltaic panels
Installing a self-consumption system at home is an increasingly common option among families in our country thanks to the many advantages it offers. These are some of the main ones.
Energy as an inexhaustible resource
Unlike fossil fuels such as oil and natural gas, which are limited resources that run out over time, solar energy is an inexhaustible and unlimited resource. Moreover, solar energy is abundant and available all over the planet, which is why it is considered one of the key pillars to achieve an energy transition towards a more sustainable, cleaner and economically viable source.
Savings on electricity bills
Once the photovoltaic system is installed in your home, you will be generating and consuming your own energy. If you manage to adapt your consumption habits as much as possible to the hours of production, you will be able to reduce your energy bill considerably, reaching savings of up to 70% per month.
Low maintenance
Solar photovoltaic panels, in general, require relatively low maintenance, as they are designed to be durable and are made of materials designed to withstand harsh environmental conditions. This means that they can withstand prolonged exposure to sun, rain, snow and wind. In addition, the tilting of the solar panels together with the action of the rain, helps to clean the dust that can accumulate on the surface of the panel.
25-year warranties
Manufacturers’ warranties for solar panels and photovoltaic system components cover manufacturing defects and guarantee long-term performance, up to a 25-year warranty. This point is essential to ensure greater peace of mind, as in the event of any defect or malfunction of any of the components, the manufacturer covers the cost of repair or replacement.
Types of photovoltaic self-consumption
Grid-connected self-consumption installations
Grid-connected self-consumption installations are considered to be those that are interconnected to the conventional electricity system. These installations allow users to generate their own energy and use it in their homes, while remaining connected to the electricity grid to supply additional demand or exchange energy. Only installations connected to the grid are eligible for surplus compensation from the distributor.
Within the self-consumption installations connected to the grid, we can distinguish two types:
Self-consumption without surplus
The electricity generated is consumed in its entirety by the home where the photovoltaic installation is located and, therefore, no surplus is discharged into the electricity grid.
Self-consumption with surplus:
When the electricity generated by the photovoltaic system is greater than the household’s consumption, surpluses are generated. These surpluses are fed back into the grid and can be compensated financially by the supplier.
Off-grid self-consumption systems
Off-grid self-consumption photovoltaic systems are those that are not connected to the electricity distribution grid, i.e. they operate completely independently. This type of installation is completely self-sufficient and independent. They are normally used in remote areas where there is no access to the electricity grid or when you want to achieve total energy independence.
In Sunhero we don’t work with off-grid solar installations.
Access to state aid and switch to self-consumption
If you are considering taking a step towards photovoltaic self-consumption, now is a good time to do so, as there are different subsidies available. The aid available may vary depending on the autonomous community or geographical region where you want to install the photovoltaic system.
On the one hand, there are subsidies or incentive programmes, which aim to encourage the installation of self-consumption systems. These programmes can offer subsidies to cover part of the costs of installing solar panels or energy storage systems. For example, the European “Next Generation” subsidies, which offer 600 euros per kWp installed.
There are also tax deductions, such as the personal income tax deduction. Depending on the energy improvement of the photovoltaic installation in your home, you can deduct between 20 and 60%. This improvement must be evaluated with an energy certificate before and after the installation.
On the other hand, there are also bonuses in the IBI (Real Estate Tax), for homeowners who have installed a photovoltaic system at home. The percentage of the rebate as well as its duration depends on each municipality.
Most of the Spanish towns and cities are offering rebates of between 30 and 50% on the IBI, with a duration of up to 5 years.

What is photovoltaic solar self-consumption?
We talk about a photovoltaic solar self-consumption system when the solar energy generated by the solar panels installed in a house is used to cover the energy needs of the same place. Self-consumption not only provides users with greater energy independence and the possibility of reducing dependence on the conventional electricity grid, but also generates economic and environmental benefits. With a photovoltaic installation we generate clean and renewable energy, reducing greenhouse gas emissions and the carbon footprint on the planet. In addition, there are subsidies and grants that promote solar self-consumption and allow users to sell the surplus energy generated to the electricity grid, receiving compensation in their electricity bill.
What are the components of a photovoltaic system?
Solar photovoltaic systems are responsible for transforming solar radiation into electrical energy. These systems are made up of several elements, each of which plays an essential role in carrying out this transformation. The main elements that make up the system are as follows: Solar panels: These are individual photovoltaic modules composed of photovoltaic cells made of semiconductor material, such as silicon. They are the component responsible for the energy transformation, as they are designed to capture sunlight and convert it into direct current (DC). Inverter: The inverter is one of the essential elements in any photovoltaic installation (whether connected or isolated from the grid). This device is responsible for converting the direct current generated by the photovoltaic panels into alternating current, which is the one we use at home with our devices. Mounting structures: Photovoltaic panels are installed on top of a structure that supports them and gives them the optimum inclination and orientation to receive the maximum amount of solar radiation. For this reason, these structures play a key role in the performance of the photovoltaic installation. Structures can be either ground or roof structures, depending on where the PV system is to be installed. Electrical wiring: The solar panels bring the direct current to the inverter through the electrical wiring that connects the entire circuit of the photovoltaic installation. Battery or accumulator: The battery is an optional element of the photovoltaic system. Its main function is to store the solar energy generated by the panels during the day for use at night or during low production hours. The batteries store the energy in the form of direct current and supply it when there is a demand for electricity in the home.
