Let''s take a practical example to illustrate the selection process. Suppose your 36V battery has an energy consumption of 300Wh per day and requires an 80% charging efficiency. the sun is your ally, and with the right solar panel size, you can charge your 36V battery efficiently while enjoying the benefits of renewable energy.

I would always choose the higher voltage panel (all other things being equal). I am running 250w panels (30.3v / 8.37a) in series sets of three to bump the voltage up to ~92-100vdc and then combining three sets (parallel) into a combiner box. Ultimately you just need to make more voltage than 14.4v, so either style panel will work.

A 100ah 48V battery holds 4800 watts, so you need solar panels that can produce at least that amount. 3 x 350W solar panels can charge the battery in 5 hours. Assuming each panel produces 350 watts an hour, that is 5250 watts total in a day. Solar panels rarely produce peak output except in ideal weather. But even so three 350W panels should be

I have a 36v golf cart that uses a bank of 6x6v batteries for the electric motor. I have an 18v solar panel here and was wondering if there was a way to put it on the roof and have it charge the batteries. My initial thought is that I could charge it either as 2 or 3 separate banks and use a battery selector to switch the banks.

Keep in mind though that 12V solar panels do NOT put out 12V, and 24V panels do NOT put out 24V. A standard 36-cell 12V solar panel has a Vmp of ~18V. A standard 60-cell panel puts out ~30V, and 72-cell 37.5V. A MPPT controller needs some overhead voltage above what the battery needs. Midnight Solar says +30%.

You can connect a 36-volt solar panel to an 18-volt battery or even use two different panels in series and the other in parallel (for example, a 24-volt and an 18-volt). It all comes down to how much power you want to pull from each at once, what you have available for modules, and how many batteries you want to charge at once.
