How Much Power Does A 9kw Solar System Produce

How Much Roof Space Do You Need For A 10kw Solar System

A 9kw solar system

A 10kW solar installation will usually require between 475 and 615 square feet of roof space.

The actual square footage you need depends on the wattage of the panels you install. The lower the wattage, the more panels you need, which increases the amount of roof space you need.

Ideally, you would want at least 475 square feet of south-facing roof space to install your panels, as this maximizes the amount of energy the panels will produce.

Power Output For A Typical 3kw Solar System

How much solar energy will a 3kW solar system produce? That depends on a number of situational factors such as location, orientation & tilt of the panels, the presence of shading and the overall efficiency of the components in the system.

Its convenient to summarise solar system output in a single figure namely, kilowatt-hours per day as in the below table. In reality there will be a significant difference in the sunlight a solar panel receives during winter months and summer months. In most cities in Australia a solar system will on average produce over twice as much energy in January than in July.

The table below provides some rough figures on average daily outputs from 3kW solar systems in a handful of Australias capital cities . All situations assume the solar panels are mounted with a north-facing aspect with a tilt equal to the latitude of the city and an overall system efficiency of 80%.

Kw Micro Inverter System

Solaray is the largest and most experienced installer of Enphase Micro Inverter systems in NSW, and our system design team are experts at putting together a professional solar array that will maximise solar output in all conditions.

The main benefit of microinverters is that each panel is independent of the others, making it possible to design an array across different orientations and at different angles. A common panel layout is to have some panels facing north, and the others west to spread the output of solar power across the day, making it easier to use more of the solar power as it is generated. Having panels west is also advantageous if you are on time of use billing, where households typically pay around 50c per kWh between 2 pm and 8 pm for power.

On larger residential systems, the panels in the middle of the array can get quite hot during summer as airflow under the panels is less than ideal. When panels get too hot, the output can be significantly reduced. Because of this, we recommend using microinverter technology and in fact, over 80% of our systems now include this technology. Find out all you need to know about Enphase: 10 key benefits of microinverter systems.

Factors That Contribute To The Cost Of Solar Panels

There are many factors that contribute to the cost of solar panels. Understanding the how and why of any cost variance will help you plan your solar installation accordingly. Lets review the elements that impact the overall cost of your solar system and how you can use them to your advantage.

The cost of solar panels has become more and more affordable as the industry grows. In fact, government incentive programs have allowed homeowners to install solar panels at a reduced cost. However, the type of solar panel system, property location, and the size of the system are variables that greatly impact the overall solar panel cost. When you are considering going solar, you should also consider these factors to determine the right system and method of installation for you.

DIY Solar Panel System – How to Do it CHEAPER!!

The amount of energy generated by any solar panel depends heavily on the irradiance for the panels location measured in kilowatt-hours per square meter per day .

For convenience, its also known as the locations Peak-Sun-Hours and can be used as a quick estimated of a solar panel arrays output per day or year measured in kWh.

Its an important number. For example, the energy output for a solar panel in Arizona with of 7.5peak-sun-hours/day is very different from Indiana with 3/day!

Kw Solar Energy System Power Output

The 9kW solar system generates between 32kWh to 40kWh of energy per day. However, the actual power output of the system depends on variables such as:

  • Location and climate
  • Quality and size of your panels and inverter system
  • Presence/absence of Shading
  • Performance of individual components of the system

The amount of sunlight in your region is the most important factor. Solar panels harness the most electricity during peak hours around 12noon or 1 pm. Since the suns peak hours vary from one region to another, your solar installation company will position the panels such that they receive as much sunlight as possible throughout the year. Typically, your system will produce more electricity during summer than in winter.

How Much Roof Space Do You Need For A 10kw System

To generate 10 kilowatts of solar energy using 60-cell panels of 275 watts would require 36 solar panels. This would therefore require 57.6m2 in roof space and generate 9,900 watts .

For systems with 60-cell panels of 300 watts you would need 33 panels. This requires 52.8m2 of roof space and generates 9,900 watts of solar energy .

Using 72-cell panels of 350 watts would require 28 solar panels. This would need 44.8m2 of roof space and generate 9,800 watts .

From these examples you can see that there are a lot of answers to the question of how much roof space you will need for a 10kW solar system. Broadly speaking a 10kW system will need between 28 and 36 solar panels. This will require between 44m2 and 58m2.

What Is Net Metering

Net Metering allows you to send any power that you are not currently using back into the grid. A separate REC meter is installed and meters all solar PV power produced so you get credit for every kilowatt hour generated by your system. Exact provisions vary from different utility companies, but the effect is to allow you to generate excess power during the day, and use it at night.

    How Much Can I Save

    If you consume more energy than you send back to the grid, a 9kW solar system will save you around $350 to $600 per bill cycle.

    But remember, youll save more if you consume the bulk of your solar power during daylight hours. Youll still be paid for any energy you export back to the grid, but its not nearly as significant as the savings youll receive if you use most if not all of your generated power.

    What About A Battery

    A storage battery will capture the unused solar power generated during the day, for use at night and on low-sunlight days. Installations that include batteries are increasingly popular. See our case study of the first Australian home to install a Tesla PowerWall battery.

    But for most homes, we think a battery doesn’t make economic sense yet. Batteries are still relatively expensive and the payback time will often be longer than the warranty period of the battery. However, it’s likely that battery technology and prices, together with future changes in how the electricity market works, will make batteries a good option for most homes within the next few years.

    And remember: for most grid-connected systems, having a battery doesn’t necessarily protect you in the event of a blackout. You may still lose all power to your home, despite having solar panels producing power and a charged battery ready and waiting. This is because grid-connected systems have what’s known as “anti-islanding protection”. During a blackout, the grid and any engineers working on the lines must be protected from “islands” of electricity generation pumping power unexpectedly into the lines.

    For most solar PV systems, the simplest way to provide anti-islanding protection is to shut down entirely. So, when it senses a grid blackout, your solar PV system shuts down and you have no household power at all.

    How Many Solar Panels To Produce 10 Kwh Per Day

    With a typical irradiance of 4 peak-sun-hours 13 solar panels rated at 200 watts each are required to produce 10kWh per day. This is a 2.5kW solar power system. Solar output will vary according to the irradiance for any geographic location.

    Ill stick with the 200 watt panels used in the last example and average irradiance of 4 peak-sun-hours.

    I already worked out that a 200 watt solar panel can generate:

    4 peak-sun-hours x 200 watts = 0.8kWh/day

    Dividing 10kWh by the 0.8kWh/day we will find the number of solar panels needed:

    10kWh/0.8kWh = 12.5 200 watt solar panels

    The total kW needed is 2.5kW.

    Note: Remember to increase the overall capacity of the solar array to take into account the 23% solar system losses commonly associated with domestic solar systems.

    Size Vs Quantity: Typical Solar Panel Ratings And Capacity

    Solar Power In Snow – Is it worth the Trouble? 4 Things To Know For Solar In The Snow

    Power output on its own is not a complete indicator of a panels quality and performance characteristics. For some panels, their high power output rating is due to their larger physical size rather than their higher efficiency or technological superiority.

    For example, if two solar panels both have 15 percent efficiency ratings, but one has a power output rating of 250 watts and the other is rated at 300 watts, it means that the 300-watt panel is about 20 percent physically larger than the 250-watt panel. Thats why EnergySage and other industry experts view panel efficiency as being a more indicative criterion of solar panel performance strength than solar capacity alone.

    In practical terms, a solar panel system with a total rated capacity of 5kW could be made up of either 20 250-Watt panels or 16 300-Watt panels. Both systems will generate the same amount of power in the same geographic location. Though a 5kW system may produce 6,000 kilowatt-hours of electricity every year in Boston, that same system will produce 8,000 kWh every year in Los Angeles because of the amount of sun each location gets each year.

    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 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 Much Roof Space Does A 9kw Solar Power System Require

    The average solar panel measures about 1.6m x 1m, and you need around 28 to 36 panels for your 9kW system. This means the panels will cover about 55m2 to 60m2 of your roof. Typically, panels that have a higher wattage will be more efficient. So, the type of panels you use will determine the actual roof space you will need for your solar power system.

    What Is The Typical Output Of A Solar Panel

    how much power does a 5kw solar system produce ...

    All solar panel systems are different, so to give you an understanding of typical solar panel output, lets look at the average for residential solar panel systems:

    • Residential solar systems tend to range in size from 2kW to 5kW
    • Typically, the bigger the system size, the bigger the output
    • An average 2kW system has an output of around 1,700kW units
    • A typical 5kW system will have an output of around 4,500kW units

    The table below shows the average output for typical sizes of residential solar panels:

    How Much Energy Does A Solar Panel Produce

    For the sake of 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 = 1,450 watts-hours, or roughly 1.5 kilowatt-hours . Thus, the output for each solar panel in your array would produce around 500-550 kWh of energy per year.

    All solar panels are rated by the amount of DC power they produce under standard test conditions. Solar panel output is expressed in units of watts and represents the panels 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 , and your total solar panel wattage plays a significant part in the overall cost of your solar system.
