Once your solar system is paid off you will have decades of free energy.
How do you set up a solar panel system.
Solar panel setups should also have a disconnect switch that will turn off the solar panel system.
While the batteries are charging you can set up the solar panels and get them wired up and ready to go.
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.
I purchased my batteries new and were only at about 60.
In fact many solar panel systems have two disconnect switches.
In a large size solar panel this junction box has terminal wires with mc4 connector but for small size panel you have to connect the junction box with external wires.
Solar panels come as 12 or 24 volts.
The first thing you want to do is charge your batteries with a charger.
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.
Wire the solar panel.
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.
This will insure they are charged to capacity and ready to go at set up.
At the back sides of the solar panel a small junction box is there with a positive and negative sign for polarity.
