How Much Electricity Does A 10kw Solar System Produce - (2023)

The amount of electricity that a solar energy system will produce will depend on a number of factors, including the quality of the parts used in the system and the angle and orientation of the solar panel array. If you are looking for a 10,000 kWh solar system, 10 kW of solar panels will produce more than enough electricity for your needs.

The most important factor determining exactly how much electricity your panels will produce is the amount of sunlight that shines in your area throughout the day. For example, all things being equal, a 10kW solar system in southern California would produce about 20% more electricity over the course of a year than a system in the Northeast.

The following table shows average daily, monthly and annual solar energy production numbers for a 10kW solar system in various US cities. As you can see, systems located in sunnier cities produce more electricity than less sunny cities.

A 10kW solar system is usually a very cost-effective way to power your home or business. How much can you expect to spend on investing in a 10kW solar system?

Typically, youll be enjoying zero power bills from day one. We expect our solar systems to pay for themselves within 4 years. And the excess after that equals money in your pocket.

Before we dive deep into calculating the power generation of one solar panel there are three major things that we need to understand which affects the power generation of solar panels.

Installation Parameters: If your solar panels are not properly oriented, not given proper inclination and installation is done in shadow affected area then the overall generation will be hampered big time. Also after installation cleaning plays a major role in maintaining the solar panels generation to expected level.

So now we know the parameters that play vital role in solar panels generation, we can calculate the power generation of one solar panel.

How much power does Chris’s 10kW solar power system in Adelaide produce?

We always advise speaking with at least a few certified solar installers to understand how all the factors will affect solar panel output for your system.

Solar panels indicate how much power they intend to produce under ideal conditions, otherwise known as the maximum power rating.

But how much electricity your solar panels produce depends on several factors.

  • Does intermittent shading obscure direct sunlight from hitting the roof?
  • How much sunlight does your roof get on average?
  • How big are the solar panels, and how efficient are the solar cells at converting energy?

Because the seasons and weather conditions affect the amount of sunlight hitting your roof, and the amount of sunlight also varies on the time day, you cant use just the solar panel ratings to predict how much power youll get. However, your location will allow you to do some math and determine how well a solar panel works where you are.

Savings And Payback On 10kw Solar Systems

The payback period for 10kW systems varies according to your electricity usage, roof orientation and pitch, shade and other property specifics. In general, however, you could expect to recover the cost of the system within a 3-8 year period, in South Australia.

The figures below are a guide, and may not reflect your actual costs.

Possible Payback Scenario

  • 3 Years

Is Your Roof Suitable For Solar Panels

You’ll want to consider the sun exposure your roof receives and the style of your roof to ensure it’s a good investment for your property. This is not only a geographical factor, with Arizona receiving the most sunlight, but also your specific environmental factors. Trees are the most common culprits for blocking sunlight, however, roof skylights and neighboring buildings can also be a barrier to your new energy source.

The orientation of the roof can also affect the amount of sunlight on the panels. Solar systems thrive best on roofs that face south. This is the result of the sun crossing the southern part of the sky from east to west. Keep this in mind when looking at installation plans as well. You want to capture as much direct light as possible, and this is best achieved with panels that are properly tilted.

How Long Does A 10kw Solar System Take To Pay For Itself

We know that it is savings that homeowners purchase solar systems for. While the large 10kW solar system comes at a higher upfront cost, its still one thats largely profitable. The average payback time for a solar system is 7 10 years. Sadly, we cant give you a better figure until we take your personal factors and circumstances in mind.

Thankfully, our solar experts are solution focused first. We are providing a free service to analyse and consult with the energy needs of those wanting to lower their electricity bill. When it comes to the best return for money, the appropriately sized system is important. We are always happy to run you through your best options, and only recommend you a solar system that offers a reasonable return for its installation.

How Many Batteries Do You Really Need

The calculations given above are straightforward enough. But it assumes that you want to store all the power your 10kw system produces in a day.

If you only want to store the excess solar energy produced, subtract the extra amount from the total output.

Example: if you use 30kw a day and the system produces 40kw:

40kw-30kw = 10kw

You need a battery bank that can hold 10000 watts.

10000 / 48 = 208ah10000 / 24 = 416ah10000 / 12 = 833ah

As usual you have to round off to the nearest battery size available. You could get 3 x 100ah 48V batteries, 2 x 250 24V batteries or 3 x 300 2V batteries.

10kw Solar System Battery Backup Power Calculation

Here is another example. Suppose you want to store enough power to last for three days, just in case there is a power failure or winter storm.

If your daily consumption is 30kw, you would need 90kw to cover three daysâ use.

90kw = 90000 watts

90000 watts / 24V = 2750ah90000 watts / 12V = 7500ah

To meet your daily power consumption over three days, you need about 5 x 400ah 48V batteries. You can use these same steps to calculate how many batteries you will need over a specific period.

Note that these calculations will fill the batteries to their capacity. If this is what you plan to do, understanding discharge rates becomes essential.

What Determines The Amount Of Electricity Produced

There are actually four main factors that will determine how much electricity your solar panels will be able to produce for your home. These are as follows:

The size. This is the most important factor out of the four, as the larger the system is, the more electricity it will produce. If you are looking at a typical installation, it is a 3.5kw system, and this tends to be around 12 panels. Alternatively, the 1kw domestic system is likely to only be two panels.

Direction. This is the next most important factor. The direction in which your roof faces and its angles are more important than you might think. For optimum performance levels and efficiency, your panels should be facing south at an angle of 35 degrees.

The area of your roof that has the solar panels installed should not be in the shade during the day. Allowing the panels to be in the sunlight all day will increase the amount of electricity that you are able to produce.

Seasons. The time of year can also have an impact on efficiency and energy production. During the summertime, there are longer hours of daylight, so you will be able to produce a lot more power. However, it is also important to remember that solar panels actually work by capturing light as opposed to heat, so it will produce energy throughout the year.

How Long Is The Payback Period For A 10kw Solar System

How Much Electricity Does A 10kw Solar System Produce - (3)

The payback period of a 10kW solar system is between 5 to 8 years. Again, it depends on the systems initial cost and the kWh rate from the electric utility.

Additionally, net metering, feed-in tariff arrangement of the local utility, and system maintenance also need to be considered. After the payback period, everything you get from the system is free energy!
