How Much Is A Solar Panel System

How Big Is A Residential Solar Panel

How much maintenance does a solar power system require?

For residential solar panels, the standard dimensions are 66×40 inches for the panel, about 1.25×1.6 inches for the frame, and each panel usually weighs about 42 pounds. While this may vary from brand to brand, its typically the same for all residential solar panels. The smaller size makes them ideal for rooftop residential installations. Read our article to learn more about how many solar panels youll need to power your home.

Is Solar Worth It

Chris Barnes from consumer index Choice, which focuses on solar and energy, said it was a no-brainer.

“For the most part, a modern home with a roof in good condition that’s not overshadowed by trees or anything solar panels just make a huge amount of sense,” he said.

Andrew Reddaway, senior consultant at the Australian Energy Foundation, whose purpose is to accelerate the take up of green energy, said solar panels can drastically cut power costs.

“If you expect to stay in the house for several years and have a sunny roof, then solar panels are very economical, especially with grid electricity tariffs rising,” Mr Reddaway said.

“By installing solar, you can expect to reduce your electricity bills by 30 per cent to 60 per cent.”

Solar Panel Installation Costs Per Kw

Considering that the average price of labor per watt is $0.50, the following chart reflects the average cost of labor for the various system sizes.

The costs of your system break down into roughly:

  • 49% equipment including solar panels, batteries, inverter, mounting hardware and wiring.
  • 35% Installation permits and labor costs.
  • 18% Operational costs including overhead, maintenance and monitoring.

When you are shopping around, do your research and get multiple quotes. You may be surprised by the difference in offers. This is owed to the significant chunk of “soft costs” integrated into the overall rate. As you can see above, the “other” category takes up about a third of your total project budget.

Buyers who explore the market thoroughly could save thousands of dollars on their installation by getting multiple quotes from both large and small installers. Expect a higher budget if the surface of your roof is more difficult to work with.

Can Your Roof Support A Solar Panel System

Armed with the knowledge of solar panel size and solar panel weight, we can make a calculation about how much a whole solar panel system weighs which in turn can help you understand whether your roof can support a new solar panel system or not.

In a 6 kilowatt solar installation made up of 20 solar panels, the panels alone will weigh approximately 800 pounds . Based on our calculation above, we know that this same system measures at 352 square feet, which works out to a weight of 2.3 pounds per square foot . When you include the mounting hardware and other equipment for your panels, the total weight will be closer to 3-4 pounds per square foot.

The roofs on most newer homes can handle significantly more than 3 pounds per square foot of weight. However, if you have an older roof or are in any way concerned about whether your roof can support the additional weight of solar panels, talk to a roofing company. A straightforward roof inspection can help you determine whether the additional weight of solar panels are a viable option for your home.

Type Of Solar Panels And Other Equipment Costs

How Much Energy Does a Solar Panel Produce?

There are three basic types of solar panels, two of which are commonly used residentially: monocrystalline and polycrystalline panels. Monocrystalline panels tend to be more energy-efficient, which can lead to greater savings in the long run, but theyre also a bit pricier on the front end.

That being said, solar panel efficiency is the name of the game for most homeowners who aim to install a system on their roof, as theyll likely have less space to work with than commercial solar projects or ground-mounted solar panel systems will.

Other components you may need to purchase include inverters, wiring, charge controllers, mounts, solar batteries and more. Consider how much backup power is a priority for your home backup batteries will add some costs on the front end, but additional safety and savings on the back.

Competition And Cheap Solar

The solar industry is one of Australias most competitive markets with over 6,000 contractors accredited with the Clean Energy Council to install solar. As a result, the margins have been forced to be very slim in the market. Unfortunately, this has driven some installers to sacrifice the quality of product and service to offer crazy prices and support them with large marketing budgets to drive high volumes. These tactics have provided downward pressure on pricing, but in most cases have not improved the outcome for consumers.

How Big Is A Solar Panel

What is the most common solar panel size for homes? For a residential solar panel, size is fairly consistent across manufacturers: 65 inches by 39 inches is the average solar panel size that you find on the roofs of houses. That is about 5.4 feet long and 3.25 feet wide, which equates to around 15 square feet. This is typically regarded as the standard solar panel size How thick is a solar panel? That also varies depending on manufacturer solar panel thickness typically ranges between 1.25 inches and 1.6 inches . How much does a solar panel weigh? Most solar panels weigh around 40 pounds because they are constructed to be able to endure constant exposure to the elements. You may be wondering, Can my roof support solar panels? Chances are good that your roof will be able to support the weight of solar panels, but a reputable solar panel installer will ensure that your roof is safe for solar panels. They will also take the weight of the average snowfall in your area into account.

How Much Do Solar Panels Cost To Install

To answer this question, lets take a look at the basic price range for solar panel installations. According to a recent report from the Solar Energy Industries Association, in the first quarter of 2021, the national average cost of a residential solar system was $2.94 per watt. To put this in perspective, this means that after the federal tax credit is applied, a 5-kW system would cost $10,878 and a 10-kW system would cost $21,756. An average residential solar system would sit somewhere between those figures.

The exact price youll pay for solar panels will depend on a number of factors and is best found by getting free quotes from local solar companies near you.

Next, you might rightly wonder: What exactly am I paying for? The solar panels themselves usually make up just about a quarter of the total system cost. Remaining expenses include labor costs, solar maintenance and additional parts and equipment .

Disadvantages Of Pv Solar Panels

  • If going off-grid, the power supply is interrupted by natural event of no energy at night
  • Upfront costs are substantial, especially if you need to be responsible for your own energy storage battery costs can easily add thousands of dollars for a basic energy storage option
  • Winter months will result in less energy being generated due to the lowered angle facing the sun and fewer daylight hours. Further, typically its the heating energy and not electric that is needed more during winter season.
  • Likewise, if PV panels are covered in heavy snow, that will hinder the solar electricity generating process of the system, unless the snow is successfully cleared off.
  • Some homeowners may find rooftop panels to be not aesthetically pleasing, or even uncharacteristic to the neighborhood
  • Not all homes, locations, and rooftops or roof orientations are suitable for solar
  • Manufacturing solar panels creates pollution, as does disposing of the old solar panels
  • Not knowing the right time to buy as costs may go down even more or better technology may be due out sooner than anticipated

The cost of your system is also dependent on the number of panels you need and the type of panels you select.

The average home solar system is 5kW, although larger homes may require a 6kW system. Assuming your system uses 250-watt photovoltaic panels, that equates to approximately 20 panels per home, at the cost of roughly $11,000. Of course, prices increase from that starting point for larger systems requiring more panels.

Home solar systems also typically require an inverter. Most solar companies will design your solar system with these components included, but selecting specific inverters or batteries, such as a Tesla Powerwall, may increase your overall cost.

Calculating Solar Power Costs

Once the above costs and benefits are determined, a solar system can theoretically be evaluated using the discounted cash flow method. Outflows at the beginning of the project would consist of installation costs , and inflows would arrive later in the form of offset electricity costs .

Rather than using DCF, the viability of solar power is usually evaluated by calculating the levelized cost of electricity , then comparing it to the cost of electricity charged by the local utility. The LCOE for household solar will typically be calculated as cost/kilowatt-hour – the same format commonly used on electricity bills. To approximate the LCOE, one can use the following equation:

LCOE = Net Present Value of the Lifetime Cost of Ownership / Lifetime Energy Output

The useful life of a PV solar module is generally assumed to be 25-40 years. The cost of ownership includes the maintenance costs, which must be discounted to find the NPV. The LCOE can then be compared to the cost of electricity from a utility remember, the relevant price is that which occurs during times at or near peak PV solar production.

How Do I Calculate A Solar Panels Output

Because every solar panel system is different, its 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 systems potential output.

How Much Do Solar Panels Cost

Switching to solar energy requires an up-front investment in equipment and comes with initial installation costs. But after that initial cost, the only recurring charge is the electricity you use beyond the power your panels generate. Assuming your solar system is the right size for your home and is properly installed and maintained, homeowners typically will see long-term savings on electricity bills and a return on their investment after several years.

The Solar Energy Industries Association estimates the national average cost of a residential solar panel system at $2.94 per watt.* For context, the per-watt price translates to just under $11,000 for a 5-kilowatt system, which is the average size of a standard residential solar system in the United States.

The price of solar panels varies by brand and retailer. Keep in mind, however, that solar panels are only a tiny fraction of the total initial cost of setting up a solar system. Installation and ongoing maintenance make up the remaining solar panel system costs.

The table below gives an overview of solar panel costs by state to help give you a general starting point for panel pricing. For comparison, the Energy Information Administration breaks down electricity prices by state for 2020 and 2021.

How Much Does It Cost To Solar Panel Your Home

The type of solar panel system you chose will greatly affect the cost. Grid-tie, grid-tie solar and energy storage, and off-grid solar are all options differ in price. Remember, the best solar panels for your property will fulfill your needs and meet your price point.

Lets break down the primary purpose of each system:

  • Grid-tie: You have access to the utility grid. Your primary goal is to save money on your electric bill
  • Grid-tie solar and energy storage: You have access to the utility grid and your primary goal is to have backup power when there is an outage.
  • Off-grid: You do not have access to the utility grid. Your primary goal is to live where it is not accessible.

Once you identify your goals, you can make a final decision based on price.

If you have access to the grid, you can lower the cost of solar panels by using a grid-tie system. When you choose a grid-tie system with energy storage, you have the potential to save even more. Storing electricity in the grid doesnt cost anything, and you may be able to sell your stored energy . An off-grid system is a significant extra cost.

With an off-grid system, youll need to purchase batteries which represent almost half the cost of an off-grid solar system.

If you have the option, we recommend connecting a grid-tied system. However, off-grid solar will still save you money in the long run if you want to live away from a utility grid.
