Short answer: single junction perovskite panels, very very unlikely to see anytime soon. Tandem junction, possibly not too far away.
As others have pointed out above, perovskite cells by themselves do suffer from output degradation at rates a bit higher than current conventional monocrystalline p-type perc panels and n-type panels, so a single junction panel will not be competitive with the status quo. But for tandem junction cells where there's a conventional monocrystalline silicon layer plus the perovskite layer, the degredation rate isn't nearly as bad simply due to the fact you have the conventional layer there that doesn't degrade anywhere near as rapidly, and the cost delta to apply the perovskite layer is fairly trivial and could be potentially come on the market in the next few years.
A couple of the tier 1 module manufacturers have built cells in MW quantities and deployed them on solar farms to test the degradation rates and at least for GCL, they've publicly stated it passed IEC 61215 and 61739 certification tests. The beauty of these multijunction modules is they achieve a higher efficiency rate than the best n-type IBC panels, like Maxeon 7 from SunPower, and most likely, if they were to mass produce the modules right now, it would be priced below those Maxeon 7 modules, which if you're in the industry, you'd know they're some pricey panels.
Solar cells reaching 30 miles a day on a car? Even with some of the best EVs on the market right now, that's some 6kwh of electricity per day, typical car at best would have about 20sqft of usable surface area for solar cells. Assuming even the most optimistic scenario of 8 hours of exposure per day, that's 750wh/hr, or 37.5w/sqft. Current best performance module yields 22.61w/sqft at STC condition. The perovskite tandem panels might get us to 30% efficiency in the next 5 years, that would get us to 27.9w/sqft, still a long ways away from that 37.5w/sqft number. This is some back of the napkin math in the most optimistic scenario, realistically, the numbers are a lot worse than that. And most people don't leave their cars in areas with no shade, and the angle of incidence can drastically reduce output numbers as well as the sun moves across the sky.
Hanwha Q Cells, LONGi and GCL are the ones I consider to be taking the lead, actively investing in R&D and furthest along in commercializing the technology. Any of these other start-offs fiddling around with some novel concept, I don't really see being a serious contender because of the massive undertaking to commercialize production in the multi-GW quantities necessary to compete with the status quo, which I'd say the same for most of the battery tech you see on the news, like IanD pointed out above.
