Oh, dude, finding solar panel manufacturers is like finding a needle in a haystack... if the haystack was Google. Just type in "solar panel manufacturers" and you'll have more options than you can shake a stick at. It's not rocket science, man.
Pool Pumps are designed and built to work hard. You may create some additional back pressure by adding solar panels. as long as the pump is sufficient to fill the solar panels with water you should have no harm done by adding solar to your pool

It depends on the vehicle, but in a lot of modern vehicles, yes, you would. It seems some years back, that most manufacturers went to putting the fuel pump directly into the gas tank.
Something that can help you in looking for a good heat pump is to look at its HSPF rating. The higher this rating the more efficient the heat pump is. A high-efficiency unit will cost more. But, operating costs will be lower, and they can add value to your home.
the water in the pond is not living
Not typically, however I suppose some auto manufacturers could do something like that. What kind/year of vehicle?
Some can be found in pond water but not all.
Yes, it is because without any algae some living animals in the pond would die. Algae can be food for some creatures in the pond. If your pond is just for admiring and not for living creatures, no, it isn't because the algae will take over the pond and no living creature is in it to eat the algae.

You HAVE A SHORT. Disconnect the pump immediately cut the electrical cord and discard the pump. Purchase a new pump and problem should be solved. Very important...... you should have a GFCI installed on the electrical line supplying electricity to the pump. Have a qualified electrician install this for you. Some one could get electrocuted. k
