How Much Voltage Should My Solar Panel Produce?
Solar panels produce electricity, but solar panel voltage refers to the amount of power that a solar panel can produce.
When you’re researching solar systems for your home or business, it’s important to know how much power they will generate so that you don’t end up with an insufficient system.
In this article, we’ll explore how much voltage can a solar panel produce also how solar panel voltage is measured and what factors influence it.
Solar Panel Voltage.
Solar panel voltage is measured in volts, just like household electricity that you get from outlets in your home.
So what does solar panel voltage mean? It refers to the amount of power a solar system can produce and it’s usually given as a range because many factors influence how much solar panel voltage a solar system will produce.

Solar Panel Size And Solar Panel Voltage.
Solar panels are rated by their wattage, but this doesn’t tell you how much power they can produce at any one time.
So it’s necessary to look at the solar panel voltage range as well.
You’ll find that most solar kit manufacturers don’t give solar panel voltage as a range, but solar inverter manufacturers will list the solar system voltage they recommend for their solar inverters.

What Voltage Do Solar Panels Generate?
Solar systems are used to only produce 12-volt DC electricity from one or more solar panels.
So if you had two solar panels wired together in series, you would have a solar panel voltage of 24 volts.
Most solar kits now produce a higher solar panel voltage than 12-volts, but this doesn’t mean that your solar system will suddenly start producing 48-volt power!
As we mentioned earlier, many different factors influence how much solar panel voltage a given solar inverter can handle.
If you have solar panels that are wired in series, the solar panel voltage will double when two solar panels are connected.
You might be wondering why this is important?
Well, if your solar inverter only accepts 24-volt solar panel voltage then doubling the number of volts doesn’t produce twice as much power!
Solar systems made up of solar panels wired in series produce solar panel voltage that is double the solar panel voltage of each solar panel, but this doesn’t always mean you’ll get twice as much power.
This phenomenon occurs because solar inverters are designed to only accept a certain range of solar panel voltages.
So if your solar system produces too high or low a solar voltage your solar inverter will shut down.
If you’re planning on using solar panels that are wired in series, make sure your solar inverter can handle the solar panel voltage from this type of configuration.
You also can select a solar kit with a high enough wattage rating for what you want to achieve.
Note: some manufacturers list two figures for solar panel voltage, for example, 12/24 volt solar panel voltage.
This means the solar panels are wired in series to produce 24-volt solar panel voltage, but that they can also be connected so that each solar panel produces 12-volts of electricity.

How Much Power Do Solar Systems With High Voltage Produce?
Many people want a higher solar panel voltage because solar panels with higher voltages will produce the same power as solar panels that have a lower voltage, but fewer solar panels.
For example, you can use four 12-volt solar panels instead of using just two 24-volts to achieve the same amount of power.
That being said, there are some disadvantages when it comes to solar panel voltage.
For example, solar inverters need to be sized correctly for a solar system that is configured with solar panels wired in series and this means they’ll usually cost more than a solar kit designed for lower voltages.
Additionally, there are safety concerns when it comes to wiring solar panels together as you have the potential of producing very high-voltage solar panel voltage.

How Much Solar Panel Output Should You Expect From Your Solar Kit?
One of the most important things to understand is that solar kits are designed for you to be able to install them by yourself.
So they’re typically smaller than solar systems installed by a professional installer.
The output from solar panels within each solar kit will vary depending on how much wattage each solar panel produces.
For example, a solar kit with four solar panels might have each of the solar panels produce 100-watts.
This means that if you connect them in series to produce 24-volt solar panel voltage (the manufacturer will list this type of information under “Maximum Power Voltage Vmp”) then you’ll be able to get 2400 watts from your solar kit.
This is the solar panel output from each solar kit, as you’re able to connect your solar panels in series with a solar combiner box and solar inverter to create a 24-volt solar system voltage.

Direct Current Volts Produced By Solar Panels Vs Alternating Current Volts Produced By Solar Inverters
It’s important to make sure you understand solar panel voltage and solar inverter input voltage if your solar kit is designed for 24-volt solar systems.
For example, a single solar panel may produce 18 volts of direct current (DC) solar panel voltage, but it’ll need to be wired in series with other solar panels so that they produce at least 36 volts of solar panel voltage.
The solar inverter will then produce an alternating current (AC) output, which is the type of electricity that every home uses daily.
You can think about this as being similar to how you need to convert your solar panel’s DC voltages into AC voltages before they can power the appliances in your home.
Note: solar panels produce the most solar panel voltage when they’re producing their maximum power rating.
Which is typically around midday or early afternoon during the summer months and less so towards mid-day throughout winter months.
Solar inverters will output a lower level of solar power when solar panels are producing at certain angles (e.g. solar panels are not set to produce maximum solar panel voltage at certain times of the day).
Solar panels produce solar panel voltage when they’re generating electricity, which is then used to charge your battery bank and power the appliances in your home.
Solar inverters convert that solar panel voltage into AC (alternating current) voltages before powering the circuit breakers and outlets of your home.
