Solar Cars at $15 billion - Just the Beginning

Solar vehicle bodywork has just progressed from curiosity to key enabling technology. The new 180 page IDTechEx report, Solar Cars, Buses, Trucks, Trains 2020-2030 explains why and forecasts the next ten years with solar cars at $15 billion 2030 just a beginning. The focus is mainly road vehicles: solar already provides significant car traction power. Learn why anyone now designing a car or car-like vehicle will be inept if they do not at least consider solar bodywork, because a tipping point of viability has arrived, with big orders being placed. This is driven by newly affordable integral and conformal solar and solar sides to vehicles becoming viable (car, camper van, snow vehicle, small bus, boats). Prices drop for the more powerful single crystal silicon now preferred. Vehicles need less electricity. Targeting smaller batteries makes solar more appealing to combat battery shortages, fires with large batteries, size, weight and cost of ownership.
The situation with buses, large trucks and trains is also analysed - understand how here only special cases get at least 10% of power from on-board solar but it is becoming attractive. Learn the tipping points as new technologies become viable. Examples are affordable compound and multijunction cells (Toyota, Sharp) even as wrap (Hanergy), expanding solar, solar windows and adding on-board wind-power (several on-land and boats). New user propositions include transport-with-microgrid.
The expensive new Lightyear solar car has a substantial orderbook and record 730 km range with half the battery needed due to best drag factor and powertrain efficiency plus good solar. Compare the parameters of the most successful solar family car, the affordable Sono Motors Sion. Over 10,000 ordered puts to shame many traditional car companies making similar pure-electric, five-seater cars without solar. For now, failure to meet the 320 km/200 mile tipping point for regular pure-electric vehicles to sell well and have good resale value is no impediment. That is because it is inspiring, offering complete energy independence for the many commuters using their cars sparingly, as does Lightyear.
The report shows how energy-positive vehicles will become commercially available. With hybrids, learn how the giant Hyundai is setting the pace with one model newly offering a solar roof adding 10% to range for many light users buying it and Toyota trials generating even more power. Others need to wake up. This is now key enabling technology. Hyundai has two other solar body types planned. There are many types of car, car-like vehicle, boat and plane that can be called solar vehicles (increasing range by at least 10%). Invisible or extending solar? Spray on solar? It is all here.
The executive summary, including 36 primary conclusions, assesses sales and technology, benefits and challenges and forecasts numbers, value and value market for solar cars 2020-2030, separating premium from mainstream. In Chapter 2 Introduction see the widening choices of electric vehicle powertrain and comparison of photovoltaic parameters, benefits, challenges, performance and manufacturers. Copper-indium-gallium-diselenide thin film photovoltaics is pictured in action in four countries. Why? Best practice in solar boats and aircraft gives lessons. Ten key technologies for energy-independent electric vehicles are presented. High-power energy harvesting discussion puts it in context.
Chapter 3 explores solar cars in 18 countries with emphasis on commercial success and benefits to society. Chapter 4 looks at truly solar buses and trucks and weaker precursors. 12 countries are covered, even equatorial and Antarctic solar vehicles and multipurposing. Chapter 4 "Solar for trains" explains the modest benefit of solar on trains but huge potential of off-grid solar power for trains mainly based on trackside panels. Chapter 6 looks at "Lessons from agribots, aircraft and boats" then the report ends with Chapter 7 on future enabling technologies such as bodywork that both makes and stores energy. Learn about energy-positive and multi-mode vehicles coming; their technologies and uses. The revolutionary "zero genset" concept of IDTechEx is explained with its $100 billion yearly potential for zero-emission mobile gensets some combining transport services.
Solar Cars, Buses, Trucks, Trains 2020-2030 is part of ongoing research by globetrotting PhD level analysts in IDTechEx. They carry out technical interviews in local languages and access privileged databases and are respected presenters and consultants in the subject.
