The collector area needed to produce the specified amount of hot water is normally determined during the sizing phase. The collector area is the entire amount of solar panels used to collect sunlight. It all depends on how much heat the sun can provide, how efficient the solar collector is, and how hot you want the water to get.

To determine the appropriate size for a heat pipe solar collector, consider two key factors: insolation level and energy requirements. Energy requirement will usually take into account the volume of water and the desired rise in temperature.
The sizing of pumps and piping in solar thermal systems is determined by fluid velocity within the pipe. At velocities beyond 5 ft/sec for heated fluids, erosion corrosion begins to occur when the turbulent scouring action of the fluid eats away at the pipe wall.
Solar collectors come in a set of standard sizing of 10, 20, 22 or 30, depending on your region. Of course you can also combine collectors to increase the size. If you get an answer that is not a standard size, as a general rule, select the next size down - this will prevent producing too much heat in summer.
Theory The purpose of a solar collector is to take fluid, at some inlet temperature that is constrained by the system being heated, and deliver as much heat as possible to that fluid.
described along with the solar collector fluid properties. The efficiency of a solar collector depends on the ability to absorb heat and the reluctance to “lose it” once absorbed.
A bigger solar collector provides more hot water in the summer, but an economically sound decision should be made. It is generally wise to select a size that will provide 90% of your hot water needs in the summer.
