What is the ideal number of solar panels for my home?

Our solar energy solutions are customized. Through a simulator in our website, we identify the best solution for you based on your household consumptions and production profile.
After the simulation, you will receive by e-mail a report with the recommended system for your case. In this report you can see how many solar panels are right for you and how much you can save.

What happens to electricity that is not consumed?

The electricity surplus can be injected into the Public Service Electricity Network (RESP) or stored in batteries, if you choose to buy a solar system with batteries. If you want to sell the energy that will be injected into the grid, you will have to install some additional equipment and establish an electricity sale contract with the Last Resource Supplier (EDP Serviço Universal), with a term of 10 years, renewable for periods of 5 years.

Is it possible to have eletricity in the absence of sun?

In case of lack of sun or insufficient electricity production, you can use the energy stored in your batteries or the electricity from the grid, regardless of your electricity supplier.

You can have you EDP solar energy system from 19,90€/ month (installation and VAT included). The price varies depending on the size of the solar system.

How much do solar panels cost?

You can have you EDP solar energy system from 19,90€ per month (installation and VAT included). However, the price varies depending on the size of the solar system. We offer a wide range of systems, from 1 to 6 panels, in case of three-phase installations, and from 1 to 10 panels in single-phase installations.

See here the general conditions of the supply contract of EDP Solar Energy.

You can pay your EDP Solar Energy system in 36 monthly payments, with no down payment, regardless of your energy supplier. This payment method is available to systems up to 6 solar panels, single-phase and three-phase installations.

Presently there are no taxes on the self-consumed solar energy. However, in the current legislation it is considered that Production Units for Self-Consumption (UPAC) with power above 1.5 kW and with an installation connected to the Public Utility Electricity Network (RESP) have to pay a compensation.

This compensation is only due when the national installed power of production units for self-consumption exceeds 1% of the total power installed in the National Electrical System (SEN) and is only valid for new systems installed. In other words, this compensation is not applicable for the clients that already have systems installed in a moment where the representation is below 1% of the total SEN's installed power.

When 1% of the total power is reached, the compensation is due on the new Production Units for Self-Consumption (UPACs) installed accordingly to the following terms:

- 30% of the Economic Costs of General Interest (CIEG), as long as the UPACs' accumulated power does not exceed 3% of the SEN's installed power;

- 50% of the CIEG, when the UPACs' accumulated power exceeds 3% of the SEN's installed power.

In the Decree Law 153/2014 you may consult the detailed formula for this compensation's calculation.

The monthly compensation to be paid is fixed when the UPAC starts operating and has a duration of 10 years, depending on the UPAC's installed power.

All the energy you will consume from your solar system will no longer be purchased from your supplier. That is, what you will gain from the solar energy you consume is the tariff you pay to your electricity provider + VAT.

The savings in your electricity bill can reach 20%. If you have a simple hourly option (0,15 € / kWh), by consuming your solar energy and not buying from your supplier you will earn 0,185 € (0,15 € + VAT) for each kWh. If you choose the dual-part tariff or three-part tariff, the savings will be the price of energy during sunny hours.

If the solar system produces in excess (i.e. the energy produced exceeds the energy consumed) and you  decide to sell this electricity to the Public Service Electricity Network (RESP), the electricity surplus injected into the grid will be remunerated at the average price of the Operator of the Iberian Energy Market, deducted by 10%.

We estimate that the final selling value is on average between 0,04 € and 0,05 € per kWh, which represents about 25% of the value that you will effectively earn from self-consuming energy. You can find the detail of the formula in the Decree-Law 153/2014.

The EDP Solar Energy solution's return-on-investment period varies according to the profile consumption of each client. However, in general terms, the return-on-investment period is between 5 and 10 years. In this context, it is essential to adjust the size of the solar system to each consumption profile, in order to guarantee the shortest period for the return-on-investment.

We take care of the whole process for you in order to ensure that the system is installed in the best conditions of safety and performance.

- Inverters: 10 year warranty against manufacturing faults, for systems up to 6 panels, and 5 years for systems with more than 6 panels

- 2 year warranty on all the other equipment and installation works

Do I need any type os insurance to solar panels?

- The Decree Law 153/2014 states the need of contracting a liability insurance for the system. However, the specific conditions to its insurance will still be defined in an order to be published by the government.

- Beyond that, optionally, you can contract a solar system insurance to protect external risks and breakdowns.

In Production Units for Self-Consumption (UPACs) the solar energy is produced first to supply the house to which is associated, and only the excess energy is injected into the electric grid. In the case of Small Production Units (UPPs) all the produced energy is injected into the grid.

Production units for self-consumption (UPACs)

In UPACs, the client's earns are obtained through the energy produced by the solar system that replaces the electricity that would have been supplied by the energy supplier. Additionally and if one wants to earn from the excess injected into the grid he may do so.

There is no limit for the installed power, however the maximum installed power cannot be higher than the contracted power for that consumption unit.

Small production units (UPPS)

In the case of UPPs, the earnings come from supplying all the energy to the grid for a specific tariff valid for 15 years. This system results from a bidding process foreseen in the Decree Law 153/2014.

In the case of UPPs a maximum limit of attributed power is defined taking into consideration the contracted power for that consumption unit. The power of the photovoltaic solar system cannot exceed  250 kW.

Under the new legislation (Decree Law 153/2014), electricity produced in self-consumption should be used to supply the household consumption and it is only injected to the electric grid the excess of production (surplus).

Both EDP Solar Energy Solutions and the former EDP Microgeneration are aimed to produce electricity from solar sources, through the installation of photovoltaic solar panels.

Under the previous legislation, in EDP Microgeneration (now UPPs) all the electricity produced had to be sold directly to the public grid, at a pre-defined tariff.
