  No sun in Portugal? Maybe in rainy Porto.

    There are those things called nights, clouds and shorter winter days 🤷‍♂️

      There is also such things as other power sources and demand variations 🤷‍♂️ Very few people run their electric stoves at 2am.

      Look, this is not rocket science. It works well in other EU countries. No one claimed that PV could cover 100% of the electricity demand without storage.

        Other things run through night such as heat pumps, water heaters, EV charging etc. And those other sources are usual fossil fuel based which emit a lot of pollution and CO2. And it doesn’t work that well in other countries when you reach a threshold.

      Portugal has a huge installed base of hydro-generation, some of which is capable of being used to store excess energy (by pumping it up to the upper basin of the dam for later use in generation).

      The mix of lots of hours of sunlight, the country being not so hot that solar panels suffer from lower efficiency due to heat and hydro-generation which can be used for storing excess power produced for use later, makes the country pretty much optimal for solar generation.

      No, the reason for the crap legislation can probably be found in the deep incestuous relationship between the two main political parties and the largest power generation company of the country alongside Portugal being one of the most corrupt countries in the EU.

        Well, I doubt it a bit how much pumped hydro capacity is there in Portugal, but you’d need an obscene capacity if you wanted to go full renewable partially based on solar panels. Found this by quick search:

        "However, the dependency on electricity imports from Spain will increase significantly, especially in drier years. " www.sciencedirect.com/…/S2352152X24037800

        Basically you’d be using Spain as energy source when you don’t have enough energy at hand.

  Portugal is so sunny that Lisbon is literally the city of Europe with the most hours of sunlight per year.
