At the back sides of the solar panel a small junction box is there with a positive and negative sign for polarity.
How do you set up a solar panel system.
The first thing you want to do is charge your batteries with a charger.
Once your solar system is paid off you will have decades of free energy.
While the batteries are charging you can set up the solar panels and get them wired up and ready to go.
So if a 12 volt battery is connected to the system you will need a solar panel s rated at 12 volts and vice versa.
For example if you have a cabin that you can t connect to a power grid and you don t want to rely on a traditional gasoline powered generator you might consider installing a small photovoltaic solar power system.
Solar panels come as 12 or 24 volts.
Once the battery s has been connected and the charger display or status lights turn on you are ready to connect the solar panels.
Wire the solar panel.
A dc disconnect which disconnects the dc current between the solar panels and the inverter and the ac disconnect which will disconnect your inverter from the grid with grid tied systems.
This will insure they are charged to capacity and ready to go at set up.
Solar panel setups should also have a disconnect switch that will turn off the solar panel system.
I purchased my batteries new and were only at about 60.
Most residential solar power systems are referred to as grid tied systems meaning they are still connected to the power grid and can utilize it for backup power whereas in remote areas with undeveloped land and limited access to grid power off grid systems are more common.
