After you buy your home in Portugal, you might be interested in energetically renovating it, since this is not only more efficient, but also cheaper long-term, with various financial aids from the Portuguese government and European Union. One of the ways through which you can achieve this is Solar panels. Let''s understand them better.
The decentralized private electricity production is currently regulated by a Decree-Law which establishes the legal regime applicable to the production of electricity for self-consumption in the installation of use associated with the respective production unit, with or without connection to the public electricity grid, based on renewable or non-renewable production technologies, called UPAC (Unidades de Produção para Autoconsumo=Production Units for Self-Consumption).
It is made up of a single crystal of ultra-pure silicon and is considerably more efficient than the others – between 15% and 25% more. So, strictly technically speaking, this is your best option. But, of course, monocrystalline panels are much more expensive. If you do have the means, though, their durability (estimated at more than 30 years) and efficiency can prove massively advantageous in the future.
This is the monocrystalline''s less successful younger sibling. Polycrystalline panels, as the name indicates, are made of multiple, less pure silicon crystals – like copper and iron. This results in an efficiency that is significantly lower than monocrystalline – at around 15%. Of course, this also makes it cheaper, which is a plus. However, the loss of efficiency and high sensitivity to high temperatures make polycrystalline less reliable.
As the name suggests, bifacial panels are made up of two cell faces. The upper one faces the sun directly, absorbing the light, while the lower one captures the indirect radiation that''s reflected by the area the panel occupies. This means that their efficiency depends directly on the reflective capacity of this said area. If this capacity is good, they can be highly efficient.
This type of panel is made up of very thin structures that can be set up on roof tiles, glass, and masonry. Their thinness makes them light and the fact that they are made of amorphous silicon, cadmium telluride, and/or gallium gives them flexibility, also. This option is, most of the time, chosen for aesthetic purposes and large-scale projects, due to its cheaper price point. However, their efficiency is lower (7-10%), since thin film panels have a much harder time during low temperature/low sunlight season. Plus, its lifespan is only around fifteen years.
The definite plus of this hybrid model is that it works as both a solar and thermal panel. During summer – at high temperatures and sunlight – this is the most efficient type of panel. Plus, it is also very durable and resistant. However, much like the monocrystalline solar panel, its efficiency makes it more expensive. Hybrid models are also rather recent, so they aren''t marketed as much as the other panels – yet. But, technically speaking, they are a great option.
These can''t be considered solar, since they are not made up of solar cells and only produce heat. There are three types of solar thermal panels:
Yes, it is possible. The important thing is that you sell the surplus solar energy that exceeds your own use and that you don''t install the panel just to sell it. The prices for surplus solar energy range between 4 cent and 8 cent in Portugal. It does not really compensate the investment. So you should only install the solar panel system based on you own consumptions needs. It does make sense to install as well a battery. In Portugal you will need a lot of engery as well during the night.
To sell surplus solar energy from your solar panels you need to meet these 5 requirements:
Before going ahead withenergetic renovationsand investing in solar panels, you should get informed about the different types of this equipment and figure out which one would work best for you. But first, get to know some advantages and disadvantages of solar panels with us.
This program promotes state reimbursement for the purchase of solar panels. This contribution can go up to 85% with a maximum limit of €1,000 in the districts of Lisbon or Porto, or €1,100 in the rest of the country, for systems without batteries. For systems with battery, the reimbursement can go up to 85% with a maximum limit of €3,000 in Lisbon or Porto; and €3,300 in the rest.
The Government provides an Efficiency Voucher, worth €1,300.00 + VAT, to help improve the energy conditions of buildings. To benefit from the Efficiency Voucher, you must be a beneficiary of the Social Electricity Tariff and the owner (and resident) of your own permanent home. At the moment, applications for the last vouchers closed on 31.05.2023, but a new initiative is due to be implemented soon.
Casa Eficiente 2020 facilitates the granting of loans on favorable terms to people who want to carry out sustainable interventions in their properties, like installing solar panels.
In 2022, the VAT applicable to the installation of solar panels in Portugal was reduced from 23% to 6%. In Madeira and the Azores, the applicable VAT rate is 5% and 4%, respectively.
A robust, asbestos-free roof covering and a roof surface that is as shadow-free as possible are essential requirements. For a PV system, a roof pitch of 30 degrees and a south-facing orientation are optimal. A solar system''s ability to produce power can be diminished by up to 10% by inclinations of less than 25 degrees or more than 60 degrees. For this reason, the surface orientation and sun radiation are quite important. An area of around 6 square meters is required to install around 1 kWp of system output.

Solar power is a growing source in the Portuguese energy mix. At the end of 2020, solar power installed capacity totalled 1.03 GW and represented 3.6% of total power generation in 2020.[1][2]
Portugal has set a goal of between 8.1 GW and 9.9 GW in installed capacity by 2030.[3]
The Serpa solar power plant is an 11 megawatt plant covered 150 acres (0.61 km2) and employs 52,000 PV panels. The panels are raised 2 meters off the ground thus allowing grazing to continue. The plant provides enough energy for 8,000 homes and saves an estimated 30,000 tonnes of carbon dioxide emissions per year.[4]
On 9 October 2021, the largest solar power plant in Portugal was inaugurated in Alcoutim. With an installed capacity of 219 MW, the power plant has 661,500 solar panels and can power the needs of 200,000 homes. It occupies an area of 320 hectares and will prevent the emission of 326,000 tons of carbon dioxide every year.[5] It surpassed the 62 MW Moura Photovoltaic Power Station.
Amid the economic challenges posed by Covid-19, Portugal announced a EUR 9.2 billion stimulus package in March 2020. This encompassed various measures, including expediting permits and grid connections for 220 solar photovoltaic (PV) projects. The primary goal was to stimulate economic recovery, create jobs in renewables, and enhance the country''s solar capacity. Additionally, these initiatives aligned with Portugal''s commitment to reduce fossil fuel dependence and advance decarbonization.[6]
In 2019, a competitive auction for a new PV plant saw a worldwide record low bid of €14.76 per MWh, well below other generating technologies.[7] The auction awarded 1.150 MW of solar capacity to various companies, significantly more than the total installed capacity at the time.[8] A 2020 auction saw a price of €11.16 per MWh.
Solar power interest is growing exponentially in Portugal. João Galamba, the State Secretary for Energy, announced that more solar auctions would take place, including one in the second quarter of 2020 as well as that there were over 80,000 MW (80 GW) in projects awaiting analysis and approval.[9]
Another solar auction is set to launch between October 2021 and November 2021.[10] A total of 400 MW in floating solar power at dam reservoirs will be auctioned.[11]
In addition to tenders for large scale power plants, Portugal has set a framework for the installation of small scale rooftop solar installations which came into force in January 2020.
