    Power output or wattage is an important factor to consider when comparing solar panel options. You may hear your solar installer say, “it’s a 255 Watt panel” or “the panel I am recommending is has a solar panel wattage of 300.” Or, when you are reading a quote from a solar installer, you might see numbers like 245W, 300W, or 345W next to the name of the panel. They are all referring to a solar panel’s wattage, capacity and power output.

    Key takeaways about solar panel output

    Currently, most solar panels on today’s market usually produce between 250 and 400 Watts of power — your actual output will depend on factors like shading, orientation, and sun hours.

    With a 30-panel system, you’ll be producing more than enough electricity per year to match all of your electricity usage, and maybe more!

    What factors determine solar panel output?

    Before calculating the amount of energy a solar panel can produce, it’s important to understand the two key factors that determine its power output: cell efficiency and solar panel size.

    Let’s assess each factor separately to understand them a bit better.

    Solar panel efficiency and output

    Today, most silicon-based solar cells can convert about 20 percent of the sunlight that hits them into usable solar energy, which has led to panels exceeding 400 watts of power. Higher efficiency = more energy, so high-efficiency solar panels generally will produce more electricity for your home.

    Number of solar cells and solar panel size

    To make things easy, we can divide solar panels into two size groups: 60-cell solar panels and 72-cell solar panels. Usually, 60-cell solar panels are about 5.4 feet tall by 3.25 feet wide and have an output of about 270 to 300 watts. On the other hand, 72-cell solar panels are larger because they have an extra row of cells, and their average output is somewhere between 350 to 400 watts. 72-cell panels are usually used on larger buildings and in commercial solar projects, not on residential homes.

    What brand of solar panels produces the most electricity?

    The average range of most solar panels available to day is 250-400 watts. Currently, SunPower’s monocrystalline solar panels produce the most electricity of all solar manufacturers. Their average efficiency is almost 21%, which is slightly better than the runner- up, LG. For homes that live in areas that may not get a full day of sun all the time, or properties with fewer square meters to work with, a more efficient solar panel may be the best option.

    How much energy does a solar panel produce?

    All solar panels are rated by the amount of DC (direct current) power they produce under standard test conditions. Solar panel output is expressed in units of watts (W) and represents the panel’s theoretical power production under ideal sunlight and temperature conditions. Most home solar panels on the market today have power output ratings ranging from 250 to 400 watts, with higher power ratings generally considered preferable to lower power ratings. Pricing in solar is typically measured in dollars per watt ($/W), and your total solar panel wattage plays a significant part in the overall cost of your solar system.

    For example, if you are getting 5 hours of direct sunlight per day in a sunny state like California you can calculate your solar panel output this way: 5 hours x 290 watts (an example wattage of a premium solar panel) = 1,450 watts-hours, or roughly 1.5 kilowatt-hours (kWh). Thus, the output for each solar panel in your array would produce around 500-550 kWh of energy per year.

    What can you power with a single solar panel?

    In the example above, the solar panel is producing 1.5 kWh per day, which ends up being about 45 kWh per month. That’s enough energy to power some small appliances without too much issue, but if you want to cover the energy used by your property’s climate control systems or large cooking appliances, you’ll need more solar panels. Check out our article on how many solar panels you need for your home to better understand how much solar energy your unique property needs.

    How much energy will a solar panel system produce?

    Knowing how much energy a single solar panel produces is all well and good, but more importantly, how much solar power can your roof generate? Let’s do the math below:

    How much energy do solar panels produce for your home?

    Key points:

    Most residential solar panels on today’s market are rated to produce between 250 and 400 watts each per hour.

    Domestic solar panel systems typically have a capacity of between 1 kW and 4 kW.

    A 4 kW solar panel system on an average-sized house in Yorkshire can produce around 2,850 kWh of electricity in a year (in ideal conditions).

    A solar panel’s output depends on several factors, including its size, capacity, your location, and weather conditions.

    How do I calculate a solar panel’s output?

    Because every solar panel system is different, it’s hard to say exactly how much electricity yours would generate. This useful calculator by the Centre for Alternative Technology can give you a rough idea, as well as the amount of money you could expect to save.

    There are also a few general benchmarks you can use to estimate your system’s potential output.

    1. Solar panel output per day

    Work out how much electricity—measured in kilowatt hours (kWh)—your panels would produce each day by using this formula:

    Size of one solar panel (in square metres) x 1,000That figure x Efficiency of one solar panel (percentage as a decimal)That figure x Number of sun hours in your area each dayDivide by 1,000

    Read more on efficiency below.

    To estimate the number of sun hours in your area, use this calculator.


    Panel is 1.6 square metres in size:

    6 x 1,000 = 1,600

    Panel is 20% efficient:

    1,600 x 0.2 = 320

    Your area gets 4.5 sun hours per day*:

    320 x 4.5 = 1,440 Divide by 1,000:

    1,440 ÷ 1,000 = 1.44 kWh per day

    *The number of sun hours varies greatly throughout the year (4.5 hours is an estimate for July), and will be much lower during winter months in particular.

    2. Solar panel output per month

    For a monthly total, calculate the daily figure then multiply it by 30:

    1.44 x 30 = 43.2 kWh per month

    3. Solar panel output per square metre

    The most popular domestic solar panel system is 4 kW. This has 16 panels, with each one:

    around 1.6 square metres (m2) in size

    rated to produce roughly 265 watts (W) of power (in ideal conditions)

    To work out the output per square metre, use this formula:

    Number of panels x Capacity of solar panel systemCapacity ÷ Total size of system (number of panels x size of one panel)


    16 panels of 265 W each:

    16 x 265 = a capacity of 4,240 kW

    Total size of the system (16 panels of 1.6 m2 each)

    4,240 ÷ 6 = 165 W per m2

    How many watts does a solar panel produce?

    Most residential solar panels on the market today are rated to produce between 250 W and 400 W each.

    Rated capacity is explained below.

    How much electricity does a 1 kW solar panel system produce?

    A 1 kW system of solar panels can generate around 850 kWh of electricity each year.

    How effective are solar panels?

    The following factors influence how much electricity your solar panels will generate:


    The maximum amount of electricity the system can produce under ideal conditions (known as ‘peak sun’).

    Sometimes called ‘rated capacity’ or ‘rated output’, this is taken to be 1,000 watts (or 1 kW) of sunlight for every square metre of panel.

    Most domestic solar panel systems have a capacity of between 1 kW and 4 kW.


    How much sunlight solar panels can turn into electricity.

    Because conditions for solar panels are never perfect, they will never be 100% efficient. In fact, most residential panels have an efficiency of around 20%. Panels with 40% to 50% efficiency are available, but tend to be prohibitively expensive.

    It’s generally the case that higher efficiency solar panels cost more but use less roof space.


    What a panel is made of can also affect its efficiency.

    Monocrystalline panels use higher-grade silicon, making them the most efficient in terms of output and space

    Polycrystalline panels are slightly less efficient but cheaper to buy

    Your roof


    The UK’s latitude—its point on Earth in relation to the equator—is 51 degrees north, meaning the sun is always south of your house and never goes directly over it.

    This is why south-facing roofs get the best results, although solar panels will still work on roofs that face east or west.


    A roof that’s tilted at an angle of around 30 degrees is said to give the best overall performance. To read more on how roof angle affects performance, click here.

    How Much Electricity Does a Solar Panel Produce?

    The amount of energy that a solar panel produces depends on the size of the solar panel and the location it is installed. Use your solar panel production (kwh) kilowatt hour calculator to see how much electricity is generated by a solar panel where you live

    While there are many factors that affect the amount of energy a solar panel can produce, you can expect a typical single solar panel in the United States to generate about 2 kWh per day, which saves an average of $0.36 on electricity costs per day.

    Now, $0.36 doesn’t seem like a lot, but that’s just the energy savings for one panel over the course of one day. Installing a whole solar panel system, on the other hand, would save you more like $132 a month (or more!).

    What exactly determines how much electricity a solar panel will produce, and how can you figure out the amount of one solar panel’s generation? Let’s find out.

    Key takeaways

    A 370-watt solar panel will produce between 1.4 kWh and 1.9 kWh of electricity on average, per day, in the United States - which is enough to run a few small electrical loads like a TV, lights, and device chargers.

    There are two main things that influence solar panel production: the physical characteristics of the solar panel and how much sunlight the panel has access to.

    The SunPower A Series panel has a power rating of 425 W, meaning it can produce more electricity than any other residential solar panel on the market.

    Installing a whole solar panel system allows you to power your home with renewable energy, decrease reliance on your utility, and most importantly, lower your electric bill.

    What affects the amount of electricity that solar panels can produce? 

    There are several factors that affect the amount of power that will be produced by a solar panel, but there are two categories that have the most influence:

    Characteristics of the solar panel itself

    How much sunlight the solar panel has access to

    Panel characteristics 

    When it comes to power production, the most important thing to look at is the wattage, or power rating, of the panel. The wattage represents the amount of power that a panel will produce under a specific set of lab conditions, called Standard Test Conditions (STC).

    Most residential solar panels used today have a power rating of somewhere between 300 and 370 watts in size. The higher the wattage of a panel, the more electricity it can produce.

    The wattage of a panel has to do with the way the panel is constructed. The type of solar cells used, for example, influences the wattage of a panel. This is why most solar panels today use something called monocrystalline solar cells, because they’re able to generate more electricity than older solar cell technologies (namely polycrystalline solar cells).

    The number of solar cells within a panel will also impact how much energy it can produce. Typically, solar panels will either have 60 cells or 72 cells. 72-cell panels produce more electricity simply because there are more solar cells, however, they are much larger in size so they’re rarely used for residential solar.

    Amount of sunlight 

    The amount of sunlight that hits a solar panel is another big factor in how much electricity it will generate. The more sunlight available to the panel, the more electricity it can produce.

    When tested in a lab, solar panels are exposed to 1,000 watts of sunlight per meter squared over an hour. This is what is known as a “peak sun hour”, and scientists out there have figured out the amount of daily peak sun hours that various places on earth receive. Solar panels are able to produce more electricity in places with a higher number of peak sun hours.

    The following table shows how much energy a 370-watt panel could produce in different states that receive different amounts of sunlight, assuming all other conditions are the same:

    State Number of peak sun hours Daily electricity production

    Arizona 7.5  2.7 kWh

    Alaska 2.5 0.93 kWh

    California 6 2.2 kWh

    New Jersey 4 1.5 kWh

    As you can see, a solar panel can produce double the amount of electricity in sunny states like Arizona and California than it can in a not-so-sunny state like Alaska.

    You can still install solar in Alaska - this just means you would need to install three solar panels in Alaska to produce the same amount of electricity that one panel produced in Arizona.

    Other factors 

    There are a bunch of other things that go into how much electricity a solar panel will produce. Take panel temperature for example: as a solar panel gets hotter, it actually produces less electricity. Crazy, right? You can read more about how temperature affects solar production here.

    If the panel is covered in any way, whether by the shade from a tree or by dust that settles on the panel’s surface, it will produce less electricity.

    Even the slope and the direction of your roof will change the amount of solar electricity generated. In general, south-facing roofs are able to produce more electricity simply because of how the sun travels in the sky. You can learn more about whether your specific roof is good for solar here.

    How to determine how much electricity a solar panel can produce 

    So, now that we’ve covered what impacts a solar panel’s ability to produce electricity, we can get into the good stuff, aka how much electricity a panel produces.
