My 24 Volt Solar Panel Is Reading 46 Volts

Grid tie solar panels with 60 cells are often referred to as 20v nominal panels like the solarworld sunmodule 290w solar panel.

My 24 volt solar panel is reading 46 volts.

Acopower 500 watts 12 24 volts polycrystalline panel solar rv kits with 40a mppt lcd charge controller mounting brackets y connectors solar cables cable entry housing. Many modules followed with 48 to 60 cells that produced voltages that were not a direct match for 12 or 24 volt nominal system components. Open circuit voltage can vary depending on your solar panel but the readings we are usually looking for are in the range of 15 to 23v. 5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh.

Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black. The 24v solar panel means that the optimum output voltage of the solar panel is 24v at stc. Thus the output for each solar panel in your array would. The optimum working voltage can be limited with a resistor that takes the absolute voc edge off.

For the sake of example if you are getting 5 hours of direct sunlight per day in a sunny state like california you can calculate your solar panel output this way. Depending on the watt rating is on your solar panel will determine the amp. Yes the 24 volt solar panels can charge and. For example if the solar panel is rated at 175 watts and the maximum power voltage vmp is given as 23 6 volts then calculate the current as 175 watts divided by 23 6 volts which is equal to 7.

How much energy does a solar panel produce. I would suggest purchasing a proper solar panel regulator it will charge and monitor your 12v battery auto float switching from full to trickle charge. It starts to get tricky when you move away from battery based solar systems and the 12v increments are no longer necessary. Some manufacturers name the optimum voltage as vmax.

The 21 to 24volt is open no load voltage and drops to around 18volts under load. The modules acquired this name because their cell count and functional voltage ratings put them right in between the two existing categories of 12v and 24v nominal pv modules.

Here 24v is different from open circuit voltage voc. Some exceptions may apply based on panel type.
