Portugal Photovoltaic Yield: kWh per kWp per Year (2026 Data)

Point a kilowatt of solar panels at Portuguese sunshine and it repays you with about 1,600 kilowatt-hours a year - the national average photovoltaic yield is 1,600 kWh per kWp on IEA-PVPS's official survey, stretching from 1,200 in the cloudy north-west to over 1,800 in the Alentejo and Algarve¹. That single number is why Portugal plans to triple its solar fleet by 2030, why pumped hydro holds the batteries, and why 71% of everything the country consumed in 2024 was renewable².

So this page answers the yield question first - then prices the machine behind it: the hydro and solar capacity in gigawatts, the 191.4 TWh total energy appetite, the record 71% renewable share, and the sunshine map that explains every regional difference³.

Portugal photovoltaic yield: kWh per kWp per year

The direct answer: Portugal's average photovoltaic yield is about 1,600 kWh per installed kWp per year, on the IEA-PVPS national survey - the International Energy Agency's own research programme¹. The verified range around that average is wide, from 1,200 kWh/kWp in the Minho's cloudy corners to more than 1,800 in the Alentejo and Algarve south, and a Lisbon rooftop models out at about 1,578 kWh/kWp - within a whisker of the national figure, which surprises visitors who expect the capital to be the sunniest spot ⁴.

The 1,300 figure that older searches keep finding is not wrong - it is the conservative floor, the number a badly tilted, shaded, soiled installation delivers. A modern, well-sited array beats it by a third, and the yield table keeps every anchor visible: the average, the Lisbon model, the floor and the south's 1,800⁴. The sibling query Portugal solar pv yield kWh per kWp per year resolves to the same numbers - solar PV is the technology the 1,600 describes - and it is worth pinning the vocabulary: kWp measures the array's peak nameplate, the kWh are what a year of Portuguese sky actually delivers through it¹. Multiply for the wallet: one kWp at the national average produces about EUR 276 of power a year at 2025 household tariffs, so a typical 5 kWp terrace system offsets roughly EUR 1,380 of electricity annually⁵.

Yield vocabulary, one paragraph, because the searches mix three terms. Specific yield - the kWh per kWp this page leads with - measures annual production per installed kilowatt-peak. Irradiance measures the sun itself, in kilowatt-hours per square metre, and Portugal receives between about 1,500 and 1,800 of those hours-equivalents depending on whom you ask; the two numbers are related by the panel's efficiency, which is why the same sun yields less through an old panel⁴. And performance ratio - the installer's term - is the share of the theoretical yield a real system keeps, typically 80-90% when clean and unshaded. The 1,600 average already assumes that real-world haircut¹.

Orientation closes the practical file: south-facing at roughly 30-35 degrees is the textbook optimum, but east-west splits lose only about a tenth and double the morning-evening coverage - relevant in Porto's valley streets and Lisbon's east-west avenues alike. The atlas tools let a reader drop a pin on their own roof; the national numbers on this page are the benchmark to compare against ⁴.

The resource behind the yield

Yield is sunshine converted through hardware, and the sunshine is measured: the map plots IPMA's district normals, the same official series this site used for its sunny-days research³. Faro's 3,044 hours a year is the national ceiling; the interior south - Beja, Evora, Castelo Branco - all clear 2,700; and the Atlantic north-west, from Porto through Aveiro and Coimbra, sits near 2,300 hours³.

That north-south gradient of roughly 750 hours is the physical reason the specific yield spans 1,200-1,800, and why the utility-scale parks concentrate where the map turns gold: the Alentejo alone hosts more than a third of Portugal's solar generation¹. The MDPI review of PV siting reaches the same conclusion from the irradiance data - the Algarve and Alentejo combine high sunlight with the country's steadiest skies, the low year-to-year variability that makes a park's output bankable⁴.

The seasonal shape matters as much as the annual total. Portuguese sunshine concentrates where the demand is not: summer afternoons produce the surpluses that the grid exports or stores, while December delivers roughly a third of July's hours in the north. A rooftop sized for winter consumption will overshoot in summer, which is why the grid-export tariff, not the winter deficit, decides most payback calculations in the south⁵.

Hydro: the old giant that stores the new sun

The direct answer to Portugal total hydropower capacity GW 2024 is a pair of verified pieces rather than one clean number: 42 large dams above 10 MW hold 5,822 MW and average 12,997 GWh a year, and pumped storage alone exceeds 3.6 GW of that total - while the whole renewable fleet they anchor reached 21.9 GW by the end of 2025⁴. REN's fuller hydro count adds the small stations, and the small-hydro capacity question - Portugal small hydropower total capacity mw - lands inside that same fuller register, which is not extractable as a single clean table; the page flags it rather than guessing⁴.

Hydro's modern role is no longer bulk energy - it is storage. The IHA counts Portugal's operating pumped fleet at more than 3.6 GW, with a government plan backing 5 GW by 2040 and EUR 400 million committed after the 2025 Iberian blackout; the Tamega complex alone is one of Europe's largest storage sites ⁷. Water is how Portugal makes solar power available at dinner time, and the 2024 balance proved the design: hydropower was the largest renewable contributor of the year².

Solar's climb and the 2030 target

The 2025 scoreboard: 6.8 GW of solar installed, more than 1 GW added in a single year, 8.7 TWh generated - a 25% jump - and third place among the renewables behind hydro and wind¹. The National Energy and Climate Plan commits to 20.8 GW AC of solar by 2030, about three times today's fleet, with solar named the principal contributor of new capacity¹. Wind, the mature sibling, added just 64 MW in 2024 - the growth race has a winner, and it is the technology whose yield this page opened with¹.

At 8.7 TWh, solar already powers roughly one kWh in six of Portuguese consumption, and every additional gigawatt adds about 1.7 TWh at these yields⁵. That is the arithmetic behind the 20.8 GW target: it implies about 35 TWh of solar generation by 2030 if the sun cooperates - more than half of everything the country consumed in 2024⁵.

The growth has a geography, visible on the sunshine map below: the Alentejo's plains host more than a third of the solar generation, the Algarve follows the same sun, and the parks queue for grid connections along the 500 kV lines that carry it to the coast. The 2025 Iberian blackout gave this build-out a new argument - inverter-based generation must now prove it can keep the lights on in a voltage stumble, and the grid code that follows will shape which of the 20.8 target GW get built first¹.

Portugal total final energy consumption in TWh

How much is Portugal total final energy consumption twh, all fuels and all uses? Eurostat's balance answers year by year: 191.4 TWh in 2024, down from 200.8 in 2010 and up from the 173.4 austerity trough of 2013⁶. The fifteen-year shape is the country's economic biography - crisis collapse, recovery, pandemic dip, and a plateau just above 190 since 2022⁶.

Electricity is only 27% of that final bill - 51.7 TWh of the 191.4 - which is the quiet argument of the whole renewable strategy: the 71% green share of the grid still leaves transport fuels, industrial heat and home heating as mostly fossil territory⁵. Every heat pump installed and every EV sold converts part of the 140 non-electric TWh into the solar-and-hydro column this page opened with⁶. The projection on the chart is our straight line, not a forecast; a decarbonising economy can bend it downward⁵.

The renewable share of consumption

The share donut carries the headline the sector quotes: renewables covered 71% of Portugal's electricity consumption in 2024, a record 36.7 TWh, with imports and fossil generation splitting the rest². In 2025 the share eased to 68% as consumption set records - peak demand crossed 10 GW for the first time in January 2026 - even though renewable output itself rose to about 37 TWh².

Read together with the final-energy chart, the donut explains Portugal's position precisely: a grid that is already most of the way decarbonised on electricity, attached to an economy whose larger final-energy bill - the other 140-odd TWh - is the next frontier the 2030 targets aim at⁶. The 68%-71% band is not a plateau; it is a floor the storage build-out is designed to raise⁷.

For the reader calibrating: 36.7 renewable TWh against a 191.4 TWh final-energy bill means the electricity triumph covers about a fifth of the country's real energy appetite. The gap is road fuel, industrial heat and heating oil - the columns that electrification strategies promise to shrink. Every percentage point of the transport and heating shift converts fossil TWh into the electricity TWh that this page's solar and hydro charts describe, which is why the 2030 targets speak in GW of panels and GW of batteries rather than in litres of diesel avoided⁶.

Storage and the records

The storage fleet is the corridor between solar's midday surplus and the evening peak that crossed 10 GW for the first time in January 2026². Portugal operates more than 3.6 GW of pumped storage today, has committed EUR 400 million to the build-out, and plans 5 GW by 2040 - the Tamega complex in the north alone ranks among Europe's largest batteries⁷. The record books of 2024-2026 are all storage-shaped: record renewable output (36.7 TWh), record imports used as virtual storage (10.5 TWh), record peak demand, and pumped-storage generation setting its own record².

The 2025 blackout is the reason the storage story accelerated. A voltage oscillation in April 2025 dropped the Iberian peninsula for half a day, and the government's answer was the EUR 400 million storage programme and the 5 GW pumped-hydro target - a bet that water in mountains is the cheapest way to hold sunshine for later. The pumped fleet's round-trip efficiency of roughly 75-80% means a quarter of the pumping energy is the toll for firmness, a cost the system pays for the 2 h 50 Alfa Pendular and the dinner-time solar alike ⁷.

For the rooftop owner the storage question is smaller and personal: a 1,600 kWh/kWp yield means a 5 kWp array fills a household's days and exports the spring surplus; the payback maths belong to the tariff, not the sun ⁵. The utilities page carries that tariff story; this page supplies the sun.

Conclusions

1. Portugal's average photovoltaic yield is about 1,600 kWh per kWp a year - 1,200 to over 1,800 by region - on the IEA-PVPS official survey¹.
2. The renewable fleet reached 21.9 GW by the end of 2025, with solar at 6.8 GW growing faster than everything else and hydro's 5.8 GW of large dams doing the storage work¹.
3. Renewables covered a record 71% of electricity consumption in 2024 and held 68% in 2025 as demand crossed a 10 GW peak for the first time².
4. Total final energy consumption was 191.4 TWh in 2024 - still below 2010 - and electricity is only 27% of it, the frontier the electrification targets aim at⁶.
5. The solar roadmap runs from 6.8 GW today to a 20.8 GW target by 2030, which at these yields implies roughly 35 TWh of generation¹.
6. The sunshine map is the yield map: 3,044 hours in Faro against 2,295 in Aveiro, a gradient the IPMA normals measure and the Alentejo's solar parks bank on³.

The system's remaining challenge is no longer generation but flexibility: hydro reservoirs and pumped storage must balance a wind-and-solar fleet whose output swings from 20% to over 100% of demand within a single week. Interconnection with Spain acts as a virtual battery, exporting summer solar surpluses and importing winter wind lulls. Battery storage auctions and green-hydrogen pilots are the next build-out phase, aimed at converting the country's renewable abundance into industrial advantage rather than curtailment.
