we need to just install solar panels on our cars and get energy from that! that would be a far better solution. Petrol's days are limited now

A car completely covered in solar panels produces aproximatelly 1-2 horsepower in a sunny day. Good luck selling them XD

Well get people to improve the technology, otherwise it will always be bad. Compare the first car to a typical car now, there is a massive difference, but with your attitude cars would have stayed at 5mph and people would still be using horses to get to places. One day, solar panels will be good enough for our energy needs, people just need to find ways of making them better and more efficient

Solar panels can't be improved that much more. They really don't produce that much power at all.

I'm sure it's like anything else, that it can be improved if there is alot wrong with it to start with. A bit like how battery technology is supposed to be getting way more efficient in the next few years. 

Solar panels are nowadays at a 15% efficiency. You can't get over 100% efficiency, you can't produce more energy than the energy the solar panel receives from the sun, and that means in theory a car completely covered in solar panels could get at most ~10 horsepower. Before being so sure, you should read a bit about it, there are physics limits.

I know there is a limit, but solar panels can still be made more energy efficient than they are now, maybe to the point they produce a significant part of a house's electricity hopefully. And i'm not saying we should only rely on solar panels, we just need to move away from oil and coal for now and eventually gas and nuclear (needs to be made safer). We need an worthy alternative to these.
