How Many Solar Panels Do You Need For A 2000 Sq Ft Home

Estimating the number of panels based on home area is an indirect approach, since you must assume the kWh consumption. Some homes have more efficient appliances, and habits also influence electricity usage. However, average values can be calculated from official data:

  • The US Energy Information Administration estimated that the average home uses 867 kWh monthly
  • The US Census Bureau determined that single-family homes have an average area of 2467 square feet
  • When dividing these values, you obtain 0.35 kWh per square foot

Assuming 0.35 kWh for a 2,000 sq. ft. home, the estimated electricity consumption is 700 kWh. At this point, you can use the calculation procedure described in the previous section. Considering 6 peak sun hours per day and 300-watt panels, you need 16 to produce 700 kWh each month.

If you have limited roof space, the best recommendation is installing the most efficient solar panels available. This will maximize the watts installed per square foot, compensating the area limitation. Finding out how efficient solar panels are is simple: you must only divide their individual wattage and area. The panels with the most watts per square foot have the highest efficiency.

How Many Solar Panels Produce 1 Mw

The solar industry is booming. In fact, one of the fastest growing jobs in the country right now is that of a solar installer. This is because of the rapid pace at which homeowners and businesses are adopting the technology. There are a lot of numbers thrown around with solar ranging from operating voltages to amperes of current running through wires. In order to simply solar, lets take a look at a more simple question: how many solar panels does it take to produce one megawatt ?

The answer to this questions is first entirely dependent on whether you are talking about one MW AC or one MW DC. These two are calculated very differently and can have a drastic impact on the way in which the solar system operates. First, one MW of solar in AC is determined by the sum of all of the inverter nameplate capacities. For example, twenty 50 kilowatt inverters have an AC capacity of one MW. One hundred 10 kW inverters also have a capacity of one MW.

One MW is equal to one million watts. If you divide this one million watts by 200 watts per panel, we are left with needing 5,000 solar panels to produce one MW of power. If you were to use panels that were a higher wattage, such as 320 watts, you would need significantly less panels to achieve the same one MW of power.

What Are Peak Sun

Its also important to bear in mind that environmental conditions can affect the amount of energy that your solar panels produce. While a 1kWp solar PV system is expected to produce roughly 850kWh of electricity each year, in reality this figure will vary depending on the number of peak sun-hours your panels experience.

A peak sun-hour is an hour in the day when the intensity of sunlight is at least 1,000 watts per square metre. Naturally, the amount of solar radiation increases each day towards noon, and then decreases again as the sun starts to set. The seasons will also determine how many peak sun-hours there are, with the summer bringing the most, and winter bringing the least.

Here is the average number of daily peak sun-hours in the UK for each month in 2019, as reported by the Department for Business, Energy & Industrial Strategy.

Month of 2019

Once you know how many peak sun-hours you can expect, use this equation to calculate how much electricity your solar panels will generate per day:

Daily peak sun-hours x PV systems rated output x 0.85

Why 0.85? Well, when solar irradiance exceeds 1,000 watts per square metre, solar panels are rarely able to absorb more than about 85%.

So, if you have a 3kWp solar PV system, this would be its expected electricity output in the UK in July:

8.7 x 3 x 0.85 = 22.2kWh per day in July.

Meanwhile, its output in the middle of winter would be much lower:

1.4 x 3 x 0.85 = 3.6kWh per day in December.

How Many Solar Panels Will I Need

In general, if were going on the national average of 11,000 kWh of electricity used annually, and use 250 watt solar panels, we can estimate that the average home will need about 28 to 34 panels to generate enough solar energy to power the home.

How big are these solar panels? Physically speaking, the panels are about 65 inches by 39 inches for residential installations and they weigh about 40 pounds per panel. Solar panels used for commercial sites are a little bigger, but thats because commercial buildings are usually larger and can contain the size of the panels. Residential panels are smaller in size and weight because they are mainly designed for a home roof, which would need to be able to bear the weight and size of the panels themselves.

Each panel will typically contain about 60 solar cells. These solar cells are what convert the sunlight into direct current electricity. The photons from the sun react with electrons released in the solar cells to generate electricity. Something called an inverter, which is part of your solar system, will then take this direct current electricity and convert it into alternating current electricity, the type of electricity needed to power your home appliances.

Solar Panel Output Per Day

Work out how much electricitymeasured in kilowatt hours your panels would produce each day by using this formula:

Size of one solar panel x 1,000

That figure x Efficiency of one solar panel

That figure x Number of sun hours in your area each day

Divide by 1,000

Read more on efficiency below.

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


  • Divide by 1,000:
  • 1,440 ÷ 1,000 = 1.44 kWh per day

*The number of sun hours varies greatly throughout the year , and will be much lower during winter months in particular.

Find How Much Energy Solar Panels Produce In Your Area

600 watt solar panel set up

Now that you know how much electricity your home uses in a month, you need to find the amount of sunlight your area receives. This is usually measured in something called peak sun hours, which is essentially the intensity of sunlight in your area.

You can find the average number of daily peak sun hours for your state here. This number is how much sunlight you receive daily, but we need to know how much you receive monthly. To do this, simply multiply your states daily peak sun hours by 30.

The monthly peak sun hours you get tells you how many kWh of electricity 1 kilowatt of solar panels will produce in your area in one day. So, if your state receives 150 monthly peak sunlight hours, 1 kW of solar will produce 150 kWh of electricity per month.

  • WindyNation

Interestingly, most top-rated solar panel manufacturers, including the ones making the most efficient solar panels, dont produce 100-watt solar panels. This is generally because they are more focused on larger solar panels that are suitable for home installations or solar farms.

How Big Are Standard Solar Panels

Standard residential solar panels, the ones you would have installed onto your homes roof, measure on average 65 inches by 39 inches, or 5.4 feet by 3.25 feet, covering an area of 15 square feet.

There are slight measurement variations depending on the solar panels manufacturer.

For large scale solar installations like the ones built onto warehouses you could expect solar panels to measure up to 6 feet .

To understand solar panel size, you need to first understand the general makeup of the panel.

Solar panels are made up of smaller individual solar photovoltaic cells. PV cells always come in the same standard size:156 mm by 156 mm, which is approximately 6 inches long and 6 inches wide.

The majority of small scale solar installations, like the ones you are likely to get on your home, are made up of 60 solar cells.

Commercial solar installations on the other hand, are made up of 72 cells, and can go up to 98 cells or more.

Solar panel size – residential and commercial panels


1.5 – 2

Essentially, the number of cells found in a solar panel is directly responsible for its length.

See below a comparison of residential panels VS commercial panels:

Most setups, whether residential or commercial usually do not comprise of a singular solar panel.

So what sort of measurements are we looking at with a full blown solar installation, say something like a 10 kW solar system?

Your 10 kW solar system will measure 55,25 feet by 10.8 feet, covering a total of 596 square feet.

What Is The Average Area Of A Single Solar Panel

A good example of common residential solar panel would be the High Density Shingle PERC Module from Canadian Solar.

This single solar panel is capable of producing 345 watts of power .

The said solar panel dimensions are as follows: 1700 992 35 mm

To work out the total area we want to multiply the length by the width.

However, to not end up with an incredibly large measurement, we will want to convert mm into feet.

  • 1700 mm = 5.5 feet

Therefore, the average area of a modern single solar panel measures 17,6 square feet.

What Is Kwp In A Solar Panel

100 Watt Solar Panel Kit

Put simply, kWp is the peak power capability of a solar panel or solar system. All solar panels are given a kWp rating by the manufacturer, and this rating indicates the amount of energy a panel can produce at its peak performance, such as in the afternoon of a clear, sunny day.

kWp, or kilowatt peak of your panel, is calculated with a standardized test that all solar panel manufacturers must adhere to, with standardized radiance, temperature, and size. These standards are as follows:

Determine Your Daily Energy Usage

You’ll want to look to your electric bill for this information. It will usually be printed as your monthly kilowatt-hour output. To calculate your daily kilowatt-hour output, you will need to divide that number by 30, then multiply by 1000 to convert the number into watt-hours. Which translates to one watt of power sustained for one hour. This is the first step in determining your solar battery bank size.

Why A 1000w Solar System Needs A Charge Controller

Solar power is among the safest energy sources available, but it is not perfect. Solar arcing can occur, and without a charge controller you are putting the batteries at risk.

Auto Low Voltage Disconnect

As the name suggests, this safeguard automatically disconnects non essential loads from the system if the voltage drops below critical levels. This level is set in the charge controller and will vary per manufacturer. This feature is also handy in a 500 watt solar system.

If the voltage reaches this threshold, the safety trigger kicks in and automatically unloads. When the voltage is back at safe levels, the system starts charging again. This is an important feature that keeps the battery banks from overcharging.

Overload Protection

A charge controller works like a valve, regulating the current that flows into the battery. Without the controller the battery could become overloaded by the current coming in from the solar panels.

A 1000 watt solar array can overwhelm the battery circuit. This could cause malfunction or in a worst case scenario the battery might even explode.

With a charge controller this can be prevented. Adding extra protection like a circuit breaker to a solar system is recommended too.
