160w + 220w in parallel ? : r/SolarDIY
The different watts solar panels also have different voltage and current, long-term use will shorten the service life of solar panels and the built-in MPPT controller algorithm of the unit will also be inaccurate. Also, the 220W solar panel will be limited to a 160W solar panel and the effect of 1 plus 1 greater than 2 cannot be achieved."

How to Mix and Match Solar Panels
Note: To get the maximum efficiency from your system and keep your 100W panel, you should get an additional controller for your new solar panels. How to Mix Different Wattage Solar Panels.
Solar Panels in Series or Parallel: Which is Best for Your Setup?
Your choice of series or parallel wiring for solar panels directly impacts the energy sent to the charge controller, which regulates the voltage and current before delivering it to the battery bank. The battery bank stores the energy for later use, and just like panels, batteries can be wired in series or parallel to match system requirements.
Connecting Solar Panels in Series or in
However, if one panel is obstructed by shade and only produces 4V, the array''s output will be reduced to 4V per panel. Instead of 60V of production, your array will output
How to Wire Two or More Solar Panels in Parallel
If we have two solar panels with the same voltage but different wattage, there is no problem; they can be wired in parallel. 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
Wiring Solar Panels in Series vs Parallel: Which Is Better?
When installing solar panels in series, the voltage adds up, but the current stays the same for all of the elements. For example, if you installed 5 solar panels in series – with each solar panel rated at 12 volts and 5 amps – you''d still have 5 amps but a full 60 volts. There are

6 FAQs about [4v solar panels in parallel]
How to connect 4 solar panels in parallel?
For parallel connection, please connect the positive and negative cables of one module and the second module correspondingly. A parallel connection between 4 solar panels could quadruple the amperage. Voltage and wattage output remain the same. If you’re worried about the current being too low, consider wiring the four PV panels in parallel.
How to connect PV panels in series or parallel?
For connecting panels in either series or parallel, we need to start with wiring. Any PV panel will have male and female MC4 connectors, i.e. positive and negative terminals. Differences between the connections are given below: A series connection of panels means batching of panels in a line in order of positive to negative.
Should solar panels be connected in series or parallel?
When solar panels are connected in series they charge fast, and this increases their power wattage. The options to wire various solar panels in a system are either series or parallel. It is important to understand these two configurations as we have to estimate our home needs or power storage for the future.
How do you wire a solar array in series or parallel?
Wiring in series or parallel determines your PV array’s combined DC output in volts and amps. Series or parallel connections do not significantly impact the total output in watts. To connect solar panels of the same model and rated power in series, wire the positive terminal to the negative terminal of each panel in the array.
Can a 6V solar panel be wired parallel to a 12V panel?
In this case, it is possible to wire the two 6V panels in series and then wire the resultant array in parallel to the 12V panel. However, the latter type of connection is at the expense of efficiency. It is therefore essential, before making a parallel connection, to carefully check the voltage of the solar panels.
What is the difference between series and parallel solar panels?
When choosing the best setup for your solar panel system, it’s important to understand the basic differences between series and parallel connections. The main difference is how they handle voltage and current. In a series connection, the voltages from each panel add up while the current stays the same.
