1.Photovoltaic panels
Photovoltaic solar panels are capable of transforming solar radiation into electrical energy.
What is photovoltaic self-consumption?
Owners of single-family homes, buildings, or even companies are increasingly turning to photovoltaic energy to cover some or all of their electricity needs.
In addition to reducing electricity bills significantly, the use of photovoltaic energy contributes to environmental protection, as it is 100% renewable energy.
Solar panels are responsible for capturing the sun’s energy and converting it into electricity.
The panels must be fastened to the house, and they require different fastenings depending on whether they are mounted on the roof or the ground.
The photovoltaic inverter transforms this electrical energy from direct current to alternating current (220/230W). Thus, energy is already available for use in the electrical network of our home.
Optionally, it is possible to incorporate batteries into the installation. They are used to store the electrical energy produced by the panels and use it later when needed.
This is a device that registers both the amount of energy that enters a home from the electrical grid as well as the amount of energy that is injected into the grid itself. It is an essential component in a self-consumption installation with surpluses.
There must be continuous (DC) or alternating (AC) current protections.

It is the device in charge of managing the batteries, charging them when there is surplus production, and discharging them when the instantaneous photovoltaic production is not enough.
There must be continuous (DC) or alternating (AC) current protections.
When the panels do not generate enough energy and the batteries are discharged, the Genset is in charge of supplying the necessary energy.
No tolls, no taxes, and no additional costs. You only produce and consume your own energy. Your bill will be reduced from the first minute of operation.
The maintenance of solar panels is minimal. An annual inspection and cleaning are sufficient to ensure proper operation.
Technological developments have made it possible to create photovoltaic panels with a service life of more than 30 years.
Lower costs combined with greater efficiency allow for great savings month after month. This guarantees a fast return on investment.
Extending the use of your home’s roof to install solar panels will increase its value.
Producing your own electricity will reduce your dependence on electricity suppliers. You will have greater energy self-sufficiency.
In a photovoltaic system, the sun’s energy is converted into electrical energy every day and free of charge.
A photovoltaic system can qualify for a variety of grants and subsidies, such as installation subsidies, tax deductions, and property tax rebates.
You are building or have planned to build your home. You would like to enjoy a comfortable temperature in summer and winter without having to worry about the energy bill. You are looking for the best solution for today and the future.
You want to renew your old heating system. You are looking to reduce energy costs without sacrificing comfort. You are willing to invest in a more modern system, as long as this investment is amortized with the savings generated.
We can help you with your project at no cost to you. We will look for the best solution for your client. Once we have it, our engineering department will provide you with the calculations, design, and justification of the project.
Installing solar panels in your home is becoming more and more profitable every day. With a photovoltaic self-consumption installation, you can save up to 80% on your electricity bill.
To start saving, you will need to make an initial investment. For this reason, you may wonder how much it costs to install a photovoltaic self-consumption system in your home.
Several factors determine the cost of installing solar panels. The biggest factor is the size of the installation or peak power. Other factors include the type of solar panels, the quality of the components, and the type of installation.
To help you understand the price of a photovoltaic self-consumption system for a single-family house, we have created this simple guide.
The price of a photovoltaic installation in a single-family house is mainly determined by the photovoltaic panels. These, together with the photovoltaic inverter, account for 75% of the total cost of an installation, provided that it does not incorporate batteries.
The price of photovoltaic panels is largely determined by the amount of energy they are capable of generating; that is, their peak power. The price is also influenced by the type of technology used and the quality of manufacture.
According to our home’s electricity consumption, its location, and the level of self-sufficiency needed, we will need more or fewer photovoltaic panels in our installation.
The price of photovoltaic panels is around 250-300€ (panels of approximately 450-500W each) per module installed including the proportional part of the installation.
An inverter is an indispensable element in a photovoltaic self-consumption installation. It is responsible for transforming direct current into alternating current to be used in the house.
The price of a photovoltaic inverter for a single-family house ranges between 1200-1800 euros.
Batteries are used to store the power generated by the solar panels that is not consumed at the time of production.
Solar batteries are essential in off-grid installations and optional in grid-connected installations to take advantage of the energy generated rather than discharging it to the grid.
The price of lithium batteries is around 700€ per kWh of storage. For a single-family house connected to the grid, between 5-10kWh are usually installed, so the total price would be around 3500-6000 euros depending on the selected capacity.
In addition to the panels, inverter, and batteries, it is necessary to install different components for the control, monitoring, connection, and protection of the installation. The cost of these components is around 600/1000 euros for a single-family house.
Normally, the installation work for an average-sized single-family house requires 2 professionals for about 3-4 days.
This would mean an approximate cost of between 1,500€ and 1,800€.

Find out about the subsidies currently in force in our country for the installation of photovoltaic self-consumption and storage:
These aids approved by thegovernment in June 2021 contemplate various subsidizable programs related to photovoltaic self-consumption:
–Incentive program 1: Implementation of self-consumption facilities using renewable energy sources, in the service sector, with or without storage .
– Incentive program 2: Implementation of self-consumption facilities, using renewable energy sources, in other productive sectors of the economy, with or without storage.
– Incentive program 3: Incorporation of storage in self-consumption facilities, using renewable energy sources, already existing in the service sector and other productive areas.
– Incentive program 4: Implementation of self-consumption facilities using renewable energy sources, in the residential sector, public administrations, and the tertiary sector, with or without storage.
– Incentive program 5: Incorporation of storage in self-consumption facilities, using renewable energy sources already existing in the residential sector, public administrations, and tertiary sector.
The amount of this subsidy will be the sum of the Base Aid and the Additional Aid that may apply in each case.
For incentive programs 1, 2, and 3, it will be calculated as a percentageof the total eligible costs.
Programs 4 and 5 will grant aid in the form of fixed unit amounts or ‘modules’ that will partially cover eligible costs.
The maximum unit-eligible cost values and aid intensities or modules to be applied in each of the programs are as follows:
Incentive programs 1 and 2
Incentive programs 3
Incentive programs 4
Residential sector
Public administrations and the service sector
Incentive programs 5
The rest of the additional subsidies vary according to the type of program:
These grants will be valid until December 31, 2023, but as has been the case in recent calls, the grants are non-competitive; i.e., they will be processed in order of entry into the registry and until the credit is exhausted, therefore, it is important to submit the grant as soon as possible.
The starting dates for submitting applications vary according to the region.
Here are the ones that have already announced their dates:
Aside from the subsidies, which will reduce your initial investment considerably, you will also be able to claim tax deductions and property tax bonuses (up to 50% depending on the municipality where you live).
If you wish, Energanova will inform you of all these aids and process them for you free of charge.
