Pool Solar Panels Series Or Parallel

While we re not going to get too deep into the details the difference between connecting solar panels in series vs in parallel is an intermediate level solar discussion.

Pool solar panels series or parallel.

Solar panels are connected in parallel to obtain higher output current. If one panel gives you hot enough water out but cannot keep up with the usage put the panels in parallel. Analogous to voltage and current when deciding whether to put pv panels in parallel or in series. So i know the real world answer is some combination of parallel series of panels.

I m installing 16 large panels 4x12. How many runs panels in series will add the most heat with the best volume return to the pool. In most cases this is around 4 to five gpm per panel. Not tried this either but i did a design and quote for a swimming pool using 8 panels and was going to put 4 in series either side of a central flow return so two lots of 4 in series the roof layout dictated this more than thermal layout but it seemed a good compromise between max temperature and max volume output but design unproven as yet they havent come up with the money.

Now lets look at connecting solar panels in parallel. Connecting your solar panel in series vs parallel affects current flow and is dictated by your installation s setup. The connection of multiple solar panels in parallel arises from the need to reach certain current values at the output without changing the voltage. The reason for this that each panel has a rather low recommended flow rate.

So when connecting solar panels in series always try to keep the electrical properties of the solar panels identical to get the full benefit of the solar array. If one panel does not get the water hot enough for your intended use at a very low flow rate then put two panels in series. This is usually used with 12v set ups. In fact by wiring several solar panels in series we increase the voltage keeping the same current while wiring them in parallel we increase the current keeping the same voltage.

The capacity of a solar panel to produce energy is measured in watts which is calculated by multiplying a solar panel s voltage by the amps of current it produces when a solar installer builds a solar energy system they need to find the right balance of voltage and amps to ensure that the system performs well. I m thinking 2 runs in series of 8 panels but maybe 4 runs of 4 panels each would be best.
