Though mixing different solar panels is not recommended it s not forbidden and things would be ok as long as each panel s electrical parameters voltage wattage amps are carefully considered.
Does the amperage increase with each additional solar panel.
When stringing panels in parallel each additional panel increases the current amperage of the circuit however the voltage of the circuit remains the same equivalent to the voltage of each panel.
Hopefully it is less than the solar panel controller output voltage.
Measure the battery voltage.
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.
Connect the ve solar controller output lead to the ve.
When you intend to wire two panels produced by different vendors the vendors are not the problem.
Measure the solar panel controller output voltage try to get maximum voltage by angling the panels.
How much energy does a solar panel produce.
With parallel solar panels the positive terminal from one panel is connected to the positive terminal of another panel and the negative terminals of the two panels are connected together.
It may be that you can never get more than 12 13v.
You can either wire multiple panels in series to increase voltage with current amps remaining the same as any one panel or wire the panels in parallel to increase current with the voltage output remaining the same as any one panel.
Wiring solar panels in parallel causes the amperage to increase but the voltage remains the same.
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.
Since each panel is 12v and the battery bank you want to charge is 24v then you need to series your system to increase the voltage.
In arranging solar panels you have two options for modifying the power output according the ohm s law.
If it is proceed.
5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh.
Thus the output for each solar panel in your array would.
