    In China they use solar panels in the desert along with planting small plants under the solar panel to fight against desertification. One woman who won the noble peace prize over a decade ago was a Chinese woman living in the desert with her husband. She and many others have found methods to plant in the desert. I'm hoping that with the amount of incredibly skilled and talented innovative brains in this world, can come up with a solution for a greener planet. We may not see them but they exist and are working very hard for a better future.

    I was involved with solar in the UAE and sand was a major problem because the panels become ever so slightly damp with condensation in the morning and coated with a fine layer that had to be washed off. I seem to remember the efficiency dropped by up to 80%. It's the same problem with cars left out overnight. We were even looking at automated rinsing systems. It was a decade ago and I don't know if they solved the problem.

    This panel can put out close to 100 watts ua-cam.com/users/postUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.

    They can use the power for desalination plus reforestation. Plus you can put solar panels a bit higher and do some farming underneath and help for dessert animal and plants to get some shade. Multipurposing this idea can save the region and whole world eventually but you need small steps of course. Also reforestation and farming will help with extreme heats which can decrease lifetime of solar panels and increase need for cooling systems.

      Well, normally, the efficiency has depleted considerably by 30 years. Sandstorms badly scratching the panels will probably cut that lifespan down a bit. More expensive panels could be a bit more scratch resistance, but there's a limit to how tough glass can be made and it still conduct light well enough to be useful

    The Sahara solar power plant would help to solve Africa's power problems. It would provide a reliable source of electricity that could be used to power homes, businesses, and industries.
    This would have a major impact on the lives of millions of people. It would improve their standard of living and give them the opportunity to improve their lives.
    Of course, there are some challenges that would need to be overcome in order to build the Sahara solar power plant. The cost of construction would be enormous. And there would be environmental concerns about the impact of the plant on the desert.
    But these challenges are not insurmountable. With the right planning and investment, the Sahara solar power plant could be a reality. And it would be a game-changer for Africa and for the world.
    In addition to the environmental and economic benefits, the Sahara solar power plant could also have a positive impact on social development. It could create jobs, improve education and healthcare, and help to reduce poverty.
    The Sahara solar power plant is a bold and ambitious project, but it is one that is worth pursuing. It has the potential to make a real difference in the lives of millions of people in Africa.

    it could be practical though to spread probably largely decentralized solar power systems (like for one household or one village) through desert and desert-adjacent inhabited areas to replace wood and charcoal for cooking, and also provide some electricity for electronic devices to aid in education etc.. I hear areas like the sahel have long had a problem with trees being cut down for firewood, when they are desperately needed to hold off desertification and graze goats and such. countering desertification locally by use of solar power probably wouldn't make a difference for the climate, but it would help to reduce the displacement of people in those areas, which is generally going to be a huge worldwide problem in the coming decades. it would also be nice in that it would empower poor people, whereas the plans to export african solar power to europe would as usual benefit corporations and corrupt officials. well, the solar power would probably also be routed to some nearby cities, but certainly not to villages in the middle of nowhere.

    Two things that are critical in the delivery of reliable electricity is diversity and redundancy. A minimum requirement is N-1 redundancy which means you have to design a system to be capable of maintaining supply even if you lose any single element in that system. So in oversimplified terms this means you need to have roughy double of everything. So the huge quantities spoken of in this video amounts to roughly half of the real requirement. This requirement is not just for protection from equipment failures… you also have to be able to de energize and isolate system elements for repair and maintenance without requiring heinous long outages. So there’s that.
    Also, it is risky to have all of your eggs in one basket… for obvious reasons. So if Europe were to depend on a single supply from a solar farm in Africa… Europe would not have sufficient diversity of supply sources to be able to survive a disruption… Europe would require a multitude of diverse sources in different locations to have security.
    Look at the trouble Germany is presently experiencing from becoming dependent on Russian natural gas without first achieving a durable economic and strategic alliance with Russia… this is but one example of too many eggs in one basket.
    So there’s that.
    Also solar power is intermittent and can only supply during daytime and favourable weather… therefore it can only support daytime peak loads not base load. So there’s that.
    People who fantasize about a world powered exclusively by direct solar are living in a utopian dream.
    Ironically, fossil fuel based power generation is also solar power. The ultimate source of the potential energy stored in fossil fuels is from the sun. This stored solar energy is released as heat energy through combustion. So this idea that you cannot store solar energy is not true. Nature has been doing this for millennia.

    Also, another way to ship the energy generated on solar farms in the deserts would be to make liquid ammonia and it can burn on ships and generators. Tanking and shipping it at lower pressures than natural gas is technically possible. Australia is looking at exporting ammonia for ship usage soon. Eventually, one could replace current natural gas sources with Ammonia and retain the natural gas plant infrastructure already built. The water source could be seawater that is desalinated and cracked for the hydrogen. There are new catalysts that make it possible to generate ammonia without ridiculous temperatures and pressures required like the Haber Bosch process now.

      You guys are seriously complimenting it? Or did I miss the sarcasm? I felt just like I was watching a GM truck on a Transformers movie. This and the apocalyptic scenario painted for solar power (not substantiated by anything in the video, by the way), made me realize that decentralized programming won't necessarily fix the problems we had with network TVs, radio and newspapers. The video is titled "The Problem with Solar Energy in Africa", but after you watch the video, you realize there isn't much of a problem after all. When he bitches about US$150 million to connect Morocco with Spain, I was almost completely sure whoever wrote this video works for Shell or Texaco. Hell - we lose much more money if a Saudi billionaire is on a bad mood and decides to either increase or decrease oil production. I'm sorry to the people behind this video - I really do appreciate your effort to promote science. But I've just had enough of all this talk about the cost of solar power. We don't have to dig 5km down the planet's crust to get solar power. We don't have to build marine-life-extinguishing tankers to move solar power around. Concentrated solar was a bad idea to begin with, and one that could only come from the minds of fossil fuel addicts who are unable to grasp the simplicity and cleanliness of photovoltaic. Your sponsor seems like an ally on the fight for a better world. Unfortunately, your video does look like a knee-jerk appeal to Big Oil's sensitivities. Also... what's the deal about the tone when speaking about the potential political problems within North Africa's countries? What year is this - 1910? It's still OK to talk like an imperialistic dipshit in 2021? I've written too much already. Bitching about this is as useless as trying to make regular people understand why oil is killing us all. So let's just all fucking die while we complain that "solar power isn't as reliable" as dinosaur juice.

    A very important factor to take into account when dealing with African countries is the level of corruption. Those of us who live in Africa know this fact all too well.

      It's more a question of relying on energy from a single country. I doubt that Europe would have to make fewer concessions by importing energy from Australia or the US, compared to Qatar or Saudi-Arabia, or in this case Morocco or Algeria.
      Few countries can thrive without relying on global trade. Self-reliance can be very costly, and interconnectivity makes wars less attractive. But relying on any one single player is a bad idea, no matter how favourably they view you at the moment.
