Solar Panel System 12v Vs 24v

If your existing electrical system is 12v like in an rv which already wired and equipped with 12v appliances then you should stick with a 12v solar system.

Solar panel system 12v vs 24v.

You may have noticed that solar panels come in both 12v and 24v. Higher voltage residential panels tend to be fairly large and the higher voltages are more efficient and use smaller wiring. Price of a 12v solar panel can vary in between rs. A 12v dc system with a tiny inverter is difficult if not impossible to upgrade upsize.

Most residential solar systems operate at 24 or 48 volts and supply power to the house with a 230 volt a c inverter. No the total power in the battery will be the same. This is so because increasing the voltage of a system causes a reduction in the current through it and in turn reduces the size of the wires you need. This was achieved by using 12v or 24v appliances lighting that do not require an inverter.

At 12 volts the flexmax 60 fm60 400 600 can only handle up to 750 watts 24 volts 1500 watts and at 48 volts 3000 watts of solar modules. Price of a 24v solar panel can vary in between rs. Using a 24 volt supply instead of a 12 volt supply greatly reduces the wiring cost to almost half the original cost. In addition most customers seem to want more power over the years.

Other things being equal that would cause losses on 24v to be half those on 12v. I believe almost all rv systems are based on 12 volt panels. Another thing to consider the batteries typically available for use on a recreational vehicle are either 6v or 12v. The total power available from the battery is exactly the same but with lower losses in the cabling and inverter.

Instead of buying a battery which has a capacity of 1000ah at 12v 12kwh you rearrange the battery as a 24v 500ah 12kwh or 48v 250ah 12kwh. 12v solar panel is available in 10w 20w 40w 50w 125w 160w and 180w whereas 24v is available in 330w and 350w. But be careful as solar panels output a large direct current even for 24v.
