Even though you ll be hiring a professional it helps to understand what s going on.
How to wire a solar panel system.
Expect the entire process of installing a full scale photovoltaic pv system to take 90 days or more.
As clearly visible in the picture it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other one.
Wiring solar panels in parallel causes the amperage to increase but the voltage remains the same.
Wire the solar panel.
Installing a solar system to power your home is an involved process.
During shading night when there is no generating power from solar panels the battery stored energy will be used as a backup power and it.
Solar panel wiring aka stringing and how to string solar panels together is a fundamental topic for any solar installer.
The following list outlines all the things you need to do.
The following wiring diagram shows that the two 12v 10a 120w solar panels connected in parallel will charge the two 12v 100ah parallel connected batteries as well as power up the ac load through batteries and inverter during the day in normal sunshine.
If we have two solar panels with same voltage and power the connection will be very simple.
You need to understand how different stringing configurations impact the voltage current and power of a solar array.
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.
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.
