How solar-e cars relieve the power grid and improve the CO2 balance sheet-improve

The market penetration of electric cars accelerates itself. Even in the most modest scenarios of various studies, they are expected to account for 29 percent in the US and 23 percent by 2030. A significant increase compared to your current market share of only 0.5 percent. It is certain: Electro cars take more and more space in the public discussion. A question, which is sometimes very passionate, is that about the CO2 balance of electric cars, and whether the electricity is actually more environmentally friendly, as a gasoline or diesel. Even if some still do not want to believe it: they are it.

The Dutch start-up Lightyear has now set up another bill, and the CO2 calculations extended by a vehicle group: solar electric cars. Finally, Lightyear builds such a car, the Lightyear One, which is to go in production in 2020 and can be loaded both via the power grid and the solar cells integrated into the body.

In general, the environmental impact of a vehicle depends on material efficiency, production and disposal methods and energy consumption during use. This also depends strongly from the country where the car is made and driven. In countries such as Norway and France, in which CO2-poor electricity is available due to hydropower or nuclear power plants, the climate gas balance of E-Cars is better than in the US or China, where a significant amount of energy still comes from coal (25 percent or. 52 percent).

In China, where with each kilowatt hour of electricity 800 grams of CO2 arise, the climate balance of the small cityscape VW e-up is even worse than that of a small gasoline in the A-segment, so Lightyear in a current message. In the Netherlands, here each kilowatt hour of electricity only 462 grams of CO2, the climate balance of the electrical up is better than that of the small combustion.

At the Lightyear One, the thanks to the solar cells extending over the entire vehicle length, can produce a part of his driving stream directly itself, the climate balance itself is even better in the Netherlands than that of the e-up, though the solar electric car is greater larger is.

The Lightyear One has another advantage: Since he is his own solar power plant, no expensive investment in the construction of additional power plants would have to be made for him, the power grid would have to be less intensively expanded and the construction of charging infrastructure could be accomplished in a lesser extent will. Arguments with which some e-auto skeptics may have to be tapped.

A similar approach like Lightyear is pursuing the Munich E-Auto Startup Sono Motors with its Sion. Thanks to several solar panels on roof, bonnet and the doors, the small solar electricians should be able to cover up to 30 kilometers range on the day alone with solar energy. Many Sion drivers could thus do without electricity from the plug, after all, an average car is moved in Germany less than 40 kilometers per day.

And also driver of a Lightyear One see a charging station probably only very rare. At optimal solar radiation every hour of energy flows for twelve kilometers into the battery. According to the company, the solar cells of the car have the potential, energy for up to 20.To produce 000 kilometers in one year. And the great thing about it: The electricity then comes completely free of charge.

  1. In general, “Man” less drive, instead of “more and more”, as it always means “We need more and more energy”. When do we finally think “around” … or. “New”……..?
    Ideal if the majority would only drive as much as you have charged from the sun.

  2. The power grid could not be relieved unnecessably if finally bidirectional charging would be mandatory.
    That there is virtually no offer here for me is the main reason why I continue to stay with my diesel plug-in hybrid and have not bought e-car with great battery.
    The system is long known to exist, but the manufacturer block.

  3. @ Mr. GOppinger,

    Unfortunately, this is not so trivial, as the cycle resistance in a car battery is currently 1000-1200 complete charging cycles. For mains stabilization, however, you need minimum 5000 cycles to be able to reliably stabilize the network for more than 10-15 years … but with a hybrid will be quite dissatisfied alone at the next repair … a pure stromer is simply very, very rarely in a workshop ..

  4. So now serious. Does anybody believe that you can download over the pair of solar cells in the car, which can also be called a bad alignment the car can be significant in reality? Especially in.Winter is there about. nothing with rum. Would be nice if any press releases would not only be copied but maybe critically questioned about the sense of solar cells in the car.

  5. According to relevant experience, the single-beam angle of the sun on the solar cell is extremely important for the yield. The roof of the car is curved. The car is somewhere in a certain direction. Parking in the cities are surrounded by trees and skyscrapers. If you find one. Most parking is found in underground garages. Also, the Muses Maintain for your car to build a house – you call it garage. There are also carports. And where exactly you download the battery using these solar cells on the roof of the car? It would be to be bombing how high the energy costs for the production of these cells are, the additional costs when buying this car, the damaging risioco in accidents, hail, etc., The additional costs in the verification and ultimately: When I drive over a highway, where the sun can burn unhindered on the roof -How much energy generates such a solar cell at motion? And: how much more the car weighs? and. Is there a trailer (CA. 13 meters long) with battery and solar cells, so that you can drive long routes without stopping?

  6. Many say no e-car because they do not have a garage with socket and also a hybrid must be loaded constantly otherwise the system is more expensive than a pure combustion. Yes solar cells integrated in the car No journey from Stuttgart to Hamburg Too But every kWh counts and if only the load losses would compensate for several millions of cars, which although not the earth is not saving, but as well as Kleinvieh also makes mist – and gunter already said – we have to start and act for finally. So I hope that the system is prevalent and also be taken over by other manufacturers.

  7. Only what do the solar cells bring when no sun seems on it and the yield is miserable? On house roofs that are much better off and there is still a lot of potential.
    With me there is a 17 kW solar system on the roof. The ranging to make me a balance of energy, if I had a heat pump and an electric car. The latter is purchased as soon as there is a car suitable for me.

  8. So far, the E-cars were over-controlled tensioned cars. What was understandable for the beginning of the development is meaningless for the broad application.
    Why do not you look back like in the past, new techniques have gone before. Z.B. When the radio arrived 100 years ago. The then new complicated radio tubes has not built every radiology self. The radiate tubes were mutually interchangeable for all radios and have made possible production and made economically. Flashlights batteries are synonymous. On the PC, there are now USB standards over all manufacturers interchangeable with E cars, there should only be one manageable number of batteries that can be used interchangeable in the different E-cars. A committee would have to set the standards. There are new better batteries, then the old out-pulling and the new pure. Who starts with a small weak low-priced battery will notice in practice if the ranges or if he needs a greater lively battery.
    It makes sense to be a small battery installed for the basic functions and a few kilometers from home to workshop.
    At the car room for 2 larger battery bobbins that the customer can turn out and push purely. An auxiliary device in the garage.
    To the short distance, to work with one of the two larger batteries. The second battery is in the garage or carport and is loaded during the day with the solar cells on the roof. The driver comes home in the dark is exchanged the full against the empty battery. If larger routes are driven, then both batteries are cleaned and then look after the charging columns on the track. Most will notice that smaller batteries are sufficient in most cases. Battery weight which do not need to be needed in 95% of the trips must not be driven by. The second. Battery, which is connected to the solar cells, can also be used for the house supply. Come more powerful batteries on the market can modernize the user himself. The standard defined by the Panel, dimensions must be adhered to. In a gasoline car I can also use lead batteries of different manufacturers.
    Every E-car manufacturer makes everything ourselves after your own standard remain high. Firmly built-in batteries can stay with the permeaver class because there is no cost pressure in this segment.
