To design a solar pv system for any household it is necessary to consider several parameters like the available solar resource amount of power to be supplied by the system solar panel efficiency autonomy of the system off grid or connected to the grid as well as the selection of components like inverters batteries and controllers.
How are solar panels connected together.
They can be wired in parallel.
There are two ways to wire up solar panels.
Are the solar panels compatible.
If we have two solar panels with the same voltage but different wattage there is no problem.
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 allows you to connect two panels then connect them into one solar input.
Firstly lets take a look at connecting solar panels in series.
You too can connect two solar panels into one system just like we do.
On the other hand if our two solar panels have both different wattage and different voltage then parallel connection is not possible since the panel with the lowest voltage would behave like a load and would begin to absorb current instead of producing it with the.
The rule of thumb when connecting solar panels directly to a battery is never connect more than c 10 watts where c is the capacity of your battery.
Let s consider the depicted below solar panels designated for a 12v solar panel system operating at their maximum power point while delivering the depicted voltage and current that correspond to this power tracking point.
Just check a few things first.
Both have their own purpose and applications and both have different outcomes when hooking up solar panels of different wattage together.
Wiring solar panels in parallel causes the amperage to increase but the voltage remains the same.
Solar panels are usually connected in series to obtain higher output voltage.

The latter is only valid provided that the panels connected are of the same type and power rating.
In a solar power system the higher the voltage and the lower the energy losses along the cables to know the maximum system voltage we usually just need to turn the panel and read the label where the value is reported.
Scheme of solar panels connected in series.
Beyond the analysis of these components there is.
After these clarifications let s see how the series connection takes place.
