45 Watt Solar Panel How Many Amps

Like many of us who are interested in solar power i bought a harbor freight 45 watt solar panel kit for about 150 which came with three solar panels and a charge controller.

45 watt solar panel how many amps.

It s usually a good idea to round up to help. The top panel in the e series comes out at a whopping 435 watts. A 40 amp hour battery could supply 2 amps of current for 20 hours for example. To calculate the energy it can supply the battery with divide the watts by the voltage of the solar panel.

Equivalent wattage and amperage values at 12 volts. It was exciting times when i set it up several months ago to see the fr. 24 kwh 500 amp hours at 48 volts 500 ah x 48v 24 kwh. Ampere per hour rating 15 watts 12 volts ampere rating 1 25 amps then divide the battery capacity which is 50 ah by the ampere per hour rating of the solar panel which is 1 25 amps which will be the charging time.

Unbound solaredge gridtie system for 24 astronergy 72 cell modules 12 406 00. Please note that solar panels are not 12v i repeat solar panels are not 12v. Then add 10 of the charging time. 8 76 kw grid tied solar system with solaredge and 24 astronergy solar 365 watt panels.

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. 120 watts 18v 6 6 amps. 24 volt systems. The solar panel with the highest watt is the sunpower e series a commercial solar panel line.

For a 45 watt solar panel system a 12 volt battery will suit most applications. Solar panels usually range in wattage output from around 250 watts to 400 watts but some panels exceed the 400 watt mark. This is a way of representing the capacity of the battery. Any one who works out the amps of a solar panels using 12v as the voltage calculation does not understand solar or has been misinformed.
