A Toyota dealer in the Netherlands is looking to the sky for power. The Louwman Hague Toyota dealership has put almost 1,000 solar panels on the roof, and there might be some Prius hybrid batteries involved. Our Dutch isn't as good as it could be and our questions to Toyota in the US haven't turned up any definitive answers, but there is some mention that these solar panels are will someday be feeding power into a bank of Toyota hybrid batteries.

The 1,000 panels make up 1,600 square meters, about the size of 4.5 IMAX movie screens, and is the largest in
the area. They generate around a quarter of a megawatt of energy [as our readers point out, this is what the translation says, but it doesn't make sense, so we think it might mean a quarter MW of power a day], which is enough to power 80 homes. The excess electricity will go into the battery packs that have (possibly) already been used in a Prius or another of the company's hybrid. There are many examples of automotive batteries being tested as stationary back-up power sources, and maybe this Dutch solution can be used as a guide when Toyota sets up its new US headquarters in sunny Texas.

      Good on them! old batteries hooked into a massive parallel array are perfect for this application, and come at an extremely low cost.. good use of what would normally be waste due to high internal resistance and capacity loss.

      Hi i just wondered why the solar panels were not connected to the grid system and the power sold to their electricity supplier, why do they have to sore the energy are they in the wilderness? Here in the UK we sell the electricity produced for a fair price. The energy produced goes through a meter and we take the reading and then get paid for the power we produce, we have no need to store the power, could this garage not do the same? Thanks eric roberts www.batteriesontheweb.co.uk

        Why do you assume they are not connected to the grid?!?!?

      That makes more sense. As we see again and again, finding reporters who can tell power from energy is all but impossible.

      That is a nice looking solar array there. Well done. Harvest those photons to create electrons with energy!

      It is not just math but science & engineering. You gotta know the difference between power & energy before you can even do the math.

      If you can get a MegaWatt from 1600 m^2, you must have some special magic panels that the rest of the world hasn't heard of yet. That would be about 62% peak efficiency. Commercial panels now get up to a little over 20%. Maybe instead of "They generate around a megawatt of energy," (MegaWatt isn't a unit of energy, BTW), you meant they generate around a megaWatt-hour of energy each day. That's much more reasonable.

        Math is hard. (It's amazing how difficult the concepts of "power" and "energy" are for some people.)

        Something was lost in translation. Even the Google translation says this: "The panels provide a quarter megawatt of energy;" which at least has a better number but still confuses power & energy.

      The The Hague Toyota dealer's systems is providing a quarter of a Megawatt of power and the total surface of the panels is listed as roughly 8 tennis courts. According to the article, they might be using used Toyota hybrid batteries in the future. It stated that the batteries, even when 10-15 years old, are still in good enough shape to be used as stationary storage.

      I am sufficiently chastised. The post has been updated to reflect my idiocy :)
