Thank you. I assume you probably keep your car plugged in a lot at home, so did not really get the solar roof for charging the traction battery. In my case, with no option to plug in the car where I live now, the reason I went to a lot of trouble and expense (expense not just the $610, but more than $2000 to have the car delivered here from far away) to get that feature was to add to the EV miles available while parked. (My parking space here is outside in the sun. Also, I am retired, don't drive every day, so more days than not the car is parked there, not driving. So although I knew the solar charging was slow, a couple miles added per day, that was worth it to me. If however, it only works for as couple of months in the summer, not worth it. Well, too late to change it now. (Again though, none of the documentation states that.) I would still be interested to hear from others who have the solar charging roof- if none of them have EV miles (or charge percentage) added from being parked in the sun, other than in the summer? Others who have that roof, please speak up. Thank you,
So the assumption was 3 miles per kWh and perfect generation for 12 straight hours w/o control circuits chewing into the output.
You keep saying the same thing but never answer anyone’s questions. @LRO raised valid points. Chances are, it is adding some miles, albeit very few, as he said, but you are looking at the wrong display (the range guess-o-meter instead of the solar-power display). If you don’t have an electric outlet at home, you need to use a Level 2 ChargePoint station. It will take three hours, and you can do some shopping, drink some coffee, and read a book in the meantime. If you pay your landlord the installation cost, they must install a charging station in accordance with California law.
You're welcome ... Think you perhaps believed too many articles about how great the performance of the solar roof might have actually been before deciding that this was the right vehicle option for you. And certainly never understood the impact that the earth tilting in winter would have. Is it any wonder that they don't mention that in the favorable articles or marketing brochures but put an asterisk and some small type about that somewhere else? But you'll have good days to look forward to once the earth tilts in your favor again. And, if you think no one ever mentioned anything about winter performance or things like that, your Toyota owner's manual does state: ● The amount of power generated by the solar roof differs according to the season, climate, weather conditions, vehicle angle and surrounding conditions. ● If even part of the solar roof is in the shade, there may be an extreme drop in power generation. ● Clean the roof on a routine basis (Especially fallen leaves and bird droppings can lead to a substantial decrease in power generation) These are very factual statements here. I know, I was curious and tested them all out. Most people would dismiss them as not being important. I think you may be doing so too. Wish I could understand why you're so adamant to keep looking at the wrong display on your vehicle (the guess-o-meter) and coming to the wrong conclusion that your solar roof is not working at all. It's flat-out the wrong place to look. Why are you doing that? Your entire car is electrified and it doesn't all go to the wheels. Toyota has provided you places to see exactly what the solar roof is doing. Even down to what happens if a leaf sits on the roof and you've chosen to ignore it. They went out of their way and engineered a really solid solar roof system that does so much more than past generations that might have simply run a ventilation fan in the cabin. This one generates electricity used by the entire vehicle in ways you need to just accept don't show up on the EV miles (or %) of the guess-o-meter. Here's looking forward to June 21-22 when the flat roof of your Prius (and mine) is due to have the best performing day possible based on the position of the sun those days. Hope you find a sunny spot and the extra abundant power generated those days and get that extra 3 or more miles you've witnessed before.
it's hard to appreciate something you can't see, but at least you're not having the 12 volt problems that many are, especially since you don't drive much
