There are many considerations. First what you are not asking about. There are solar photovoltaic panels that produce electricity. The website that Kool referenced are photovoltaic panels. Then there are solar thermal panels that are used for solar space heating and solar hot water heating.
Then there are three general styles of solar water heating panels. There are batch heaters that have the storage as part of the panels. They are cheaper and often with few moving parts but are better used where there is no chance of freezing.
Where freezing is more likely there are pump down systems that eliminate water in the system when it might be likely to freeze and…
Then there are systems that use a heat exchanger and separate water with anti freeze in it from the hot water that it heats up and stores.
For all of these styles of systems there are solar collectors that are some variation on tubes in a box and the newer, more expensive, hi tech vacuum tube collectors. The vacuum tube collectors collect more heat on cloudy days and can get much hotter. Sometimes one vacuum tube collector is used at the end of conventional collectors or they might be used for commercial systems like a laundrymat.
You should generally be looking for a “pay back” period of between 3 to 5 years on a solar collector water heating system. How many collectors you install, what type of system you install will depend upon how much hot water you want to produce (80% of your needs is usually economical while 100% might require somewhere to dump excess heat of some days to keep collectors from overheating… like a loop in the cold earth.), what the climate is like where you live, and how much you are willing to spend initially.
