How Much Does An Average 10kw Solar System Cost

As of April 2021, a 10kW solar energy system will cost about $28,500 before incentives, based on the average cost of solar in the U.S. When you take the federal tax credit into account, that price drops to about $21,090.

Its important to keep in mind that solar system pricing varies from state to state. In some areas, additional state or utility-based solar rebates may reduce the installation cost even more.

The following table outlines the average cost of a 10kW solar system in different states, so you can get an idea of how much solar could cost in your area.

How Much Electricity Will A 10

The amount of electricity your solar panels produce depends on many factors, including the direction and angle of your roof. The most important one is how sunny it is where you live for example, a 10-kW system in East India Region generates 1500 * 15 = 15,000 Units annual.

Kw Solar Systems 7 Questions You Would Be Crazy Not To Have Answered Before You Buy

The solar power system is considered the cheapest form of energy compared to standard electricity. Installation of a solar power system is a wise decision, as it is energy-efficient and cost-effective. Installing 10kW solar systems is the best for homes, small farms, and ranches. Investing in it will never be worthless because you will find it beneficial in many ways, such as installation, energy-saving, reduction in power bills, multi-purpose usage, advanced power grid security, and many more.

Solar power systems are highly preferred in the Southwest US, South Africa, and Southeast Australia. The rise in concern for power saving and cost-effectiveness is driving the demand for a solar system. However, there are seven essential factors to recognize before investing in solar.

How Many Solar Panels Does It Take To Make 2000 Kwh A Month

If your household uses somewhere around 2000 kWh per month of electricity, and you are looking to see what size solar panel system you will need, the easiest way to determine this is to use an online solar panel calculator. With an online solar panel calculator, you can enter the number of monthly kilowatt-hours of electricity your household uses on average and then enter in your zip code. By entering your zip code, the solar calculator will automatically calculate the hours of daily sun that your area receives. However, to give some averages, if the average 2,000 kWh per month household were looking to install high-wattage solar panels from 315-watts to 375-watts, they would need a 14.34-kilowatt system consisting of anywhere from 39 to 46 solar panels depending on average daily sun hours2.

What Is The Payback Period On A 10kw Solar System

Use 100% of the solar electricity you generate and you can expect to recover the cost of the system in less than 5 years. Its impossible to predict electricity costs and export tariffs for the next 20+ years. But based on an annual increase of 5%, after 5 years youll be enjoying free electricity.

Youll need to pay something for the maintenance of your solar system. Typically, every 5 years or so, and costs between $500 and $700. Also, expect to replace the solar inverter in your system after15-20 years.

Lets look at three examples for Melbourne in more detail.

The IRR is the true comparison rate. Its much better than simply thinking about the payback period which is simply how long it takes to recover the initial investment for installation.

Using the IRR makes it possible to compare your solar system as an investment. So rather than receiving $X back after X years, the table shows that at 30% self-consumption, a 10kW system produces an IRR of 15%. Thats a 15% annual return on your investment of $13,000.

The NPV takes into account the true time value of money, inflation, and many other factors. What does it mean? Simply, $100 today will not be worth the same as $100 in 10, 15, or 20 years from now. Expressing the NPV shows the value of future cash flow in todays terms, which is much more meaningful.

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.

How Do I Calculate Kwh

It is possible to estimate a homes energy needs in kWh, but it isnt very accurate. You would have to add up all the wattages of normal appliances

You also need to guess how many hours per day a particular appliance would be used. As you can see, the approach isnt too accurate.

What I call normal appliances are those with a constant wattage i.e. you switch it on and it takes a constant amount of power in watts.

How many solar panels would you need to run air conditioning?

Some appliances arent like that. If an appliance uses a compressor, such as refrigerators, heat pumps, freezers and air conditioners , then it isnt so obvious what the average power consumption is.

These types of appliances run in cycles. That is, sometimes they are running, sometimes stopped and other times starting up. Compressor motors are subject to surge current.

For the above reason, its often difficult to estimate average watts. The best way is to simply take last years energy usage from your utility bill, which will be a good estimation of what you use.

How Much Power Does A 10kw Solar System Generate

An efficient, well-functioning 10kW solar system generates around 44 units per day.

However, how much power your 10kW system generates depends on two key factors your geographic location and the orientation and angle of your solar panel array. Youll generate more power in summer than in winter, and sunnier locations yield better results than those experiencing higher cloud levels.

Regardless of your location, our installation experts will ensure your systems positioned for the best possible results. Along with purchasing the best quality system and components you can afford, this will ensure you get the best possible return on your solar investment.

Single Phase Versus 3 Phase Power

Electricity may be supplied to your home via either a single phase or a 3-phase connection.

It depends on where you live and your power supplier but there may be restrictions on the permitted size of your solar system.

We design our system as a 3 phase system and so use one of the best 3 phase inverters on the market: the 10 kW Fronius Symo.

Is Your Roof A Good Fit For Solar Panels

You want to consider the sun exposure your roof receives and style of your roofto ensure this is a good investment for your property. This is not only a geographical consideration, with Arizona receiving the most sunlight, but also think of your specific environmental factors. Trees are a most common sun blocking culprit, however, roof dormers and neighboring buildings may also create barriers to your new energy source.

The direction of your roof will also impact the amount of sunlight on your panels. A solar system will best thrive on roofs with a southern orientation. This is a result of the suns east to west travel pattern across the southern part of the sky. Keep this in mind when reviewing installation plans as well. You want to capture the most direct rays possible, which will be best accomplished by properly tilted panels.

Savings And Payback For 10kw Solar Systems

The payback period for 10kW systems varies according to your location, electricity usage habits and your properties suitability for solar. If you use more than 30kWh / day, its possible to pay back your 10kW system within five years. If you buy good quality solar panels, you may save more than $100,000 throughout the 25-year life of your system. Below we show results from payback and savings results for a 10kW system in Brisbane:

The Type Of Solar Panel

One important factor here is the type of solar panel that you get. There are different types of solar panels, and they each have different levels of efficiency. Generally speaking, amorphous silicon solar panels are the least efficient. They feature in efficiency between 6% and 8%.

You then have your cadmium Telluride solar panels. These usually have an efficiency anywhere from 9% to 11%. You then have copper Indium gallium selenide solar panels. These usually have an efficiency level anywhere from 13% to 15%.

Next, we have polycrystalline solar panels. These generally feature an efficiency level anywhere from 15% to 17%. We then also have monocrystalline solar panels. These are usually very efficient, generally 20% and higher. You then have PERC solar panels, which are about 5% more efficient than monocrystalline solar panels.

Can You Go Off

You can go off-grid with a 10kW solar system whether your daily electricity consumption is equal to or less than the power it produces, and you have enough battery power to store 3 – 5 days worth of power.

When choosing to go off-grid with this system, there are some factors you need to consider. First, location. Does the location of your house receive sufficient sunshine for your solar system to produce power effectively and efficiently?

Second, also related to location, is the placement of your solar panels. Are they shaded, or are they in the open to receive sunshine freely?

Invite your chosen solar panel installer to your home before any installation for a free inspection and solar quote. An inspection allows them to identify the layout of the house and available roof space. They can also identify where to place the solar panels for efficient production.

When going off-grid, the most expensive part is the battery storage. As battery technology is still developing, it will come down in cost, but at the moment, you will be paying a high price, and they only come with a ten-year warranty, at which point they will need to be replaced.

There are rebates on batteries in some states like Queensland and South Australia. Still, if you can stay grid-tied for a backup, you will save a lot of money as you will only need to purchase a battery backup to store 70% of your daily usage and draw on the grid if it rains for a week straight.

Battery Discharge Rate And Capacity

If you only want to store the reserve energy, the capacities given above will be enough. But if you end up using the excess energy, the battery discharge becomes important.

Suppose you have 3 x 100 48V batteries to store the extra power produced by your system, anywhere from 10kw to 12kw a day.

If you end up using all the energy, it will fully discharge the battery. Batteries have different discharge rates , but most FLA should not be discharged below the halfway point.

Only lithium ion batteries can be fully discharged. If you have FLA batteries and end up discharging them completely, you have to double the capacity.

If your household consumes 30kw a day and your system produces exactly that amount, you do not need any batteries. But there are days when you consume less and times when you use up more.

That is where battery storage comes into play. If you consume 30kw daily and the system generates 40kw, you donât want to waste the extra power.

If you are on the grid, that extra power goes into the power company where you can access it anytime. But if you are off grid you need a battery bank for storage.

What Maintenance Needed For 10kw Solar System

Solar panels dont require much maintenance, but essential routine upkeep is necessary to know about their functions and check debris. A few care times are needed to remove dirt particles and debris in a year. In case of any issue in the system, through maintenance, it can be noticed at the earliest. It is recommended to use a cleaning spray to clean the panels. The use of water is restricted to prevent the panels from cracking risk. There are automated cleaner sprays available for cleaning it. In addition, you may use the following tips to keep your solar panels in good condition.

How Does A 10kw Solar System Work

The answer lies with what is in your solar panels solar cells or photovoltaic . These convert solar power to electricity.

In each panel, manufacturers arrange together a set of solar cells. Depending on the number of cells in each panel and their corresponding efficiency, you can determine the basic rating of a solar panel. Therefore, this explains why we can describe solar panels by the number of cells in each panel .

Heres how a solar panel works its free electricity magic when sunlight hits your solar panel, the PV cells absorb the solar energy that wakes up and moves electrons via an electrical field within the solar cell. And by definition, the created flow of electrons is the usable electric current we use to run our devices at home.

You see, solar panels utilize the first law of thermodynamics, which states that:

Energy can neither be created nor be destroyed. It can only be transferred from one form to another.

Solar panels follow this law when capturing sunlight and transforming it into electrical energy via PV cells.

Three Tips For Solar Shoppers

1. Homeowners who get multiple quotes save 10% or more

As with any big ticket purchase, shopping for a solar panel installation takes a lot of research and consideration, including a thorough review of the companies in your area. A recent report by the U.S. Department of Energys National Renewable Energy Laboratory recommended that consumers compare as many solar options as possible to avoid paying inflated prices offered by the large installers in the solar industry.

To find the smaller contractors that typically offer lower prices, youll need to use an installer network like EnergySage. You can receive free quotes from vetted installers local to you when you register your property on our Solar Marketplace homeowners who get 3 or more quotes can expect to save $5,000 to $10,000 on their solar panel installation.

2. The biggest installers typically dont offer the best price

The bigger isnt always better mantra is one of the main reasons we strongly encourage homeowners to consider all of their solar options, not just the brands large enough to pay for the most advertising. A recent report by the U.S. government found that large installers are $2,000 to $5,000 more expensive than small solar companies. If you have offers from some of the big installers in solar, make sure you compare those bids with quotes from local installers to ensure you dont overpay for solar.

3. Comparing all your equipment options is just as important
