Solar Panel Cost with Installation: Pricing Guide

Solar energy is a booming market, with an average annual growth rate of 33%. Many people are switching to solar to help the environment and move away from fossil fuels while saving on their monthly utility bills. Solar energy is abundant, and it’s no wonder people want to make the switch.

But what’s the cost of installing solar panels for the average homeowner or business? Below, we’ll guide you through the average cost of solar panels and the many incentives you can take advantage of to help you determine whether solar is a worthwhile investment for your home or business.

How Much Do Solar Panels Cost?

How much do solar panels cost on their own? How much does it cost to install solar panels? Several factors determine solar panel cost with installation. Solar panel cost itself varies from region to region and from project to project. Different manufacturers have different types of panels, using various technologies with different efficiencies, all of which affect pricing. 

The average cost of solar panel installation also varies for several reasons. Is it a residential or a commercial installation? If you talk to multiple installers like you should, there will be multiple price points for a full system installation. There are good reasons for this, however. Different installers have different preferences on all the items underneath the panels that customers never see. These racking, mounting and electrical wiring choices affect system performance and solar panel cost.

Solar tax credits also vary and can affect system pricing a lot. Furthermore, residential & commercial projects have a wide range of electricity bills that customers are trying to offset, so it is always recommended to look at these projects on a case-by-case basis.

In our opinion, it is always best to avoid cutting costs on projects by installing lower-quality mounting solutions. “How much do solar panels costs” should not be the only determinant in your purchase decision. We always recommend customers dive deep into the technical aspects of what they are purchasing and understand what they are being proposed – beyond just the solar panels and the inverters.

Why Do Similar Sized Solar Panel Systems Differ in Cost?

There are many reasons why two similarly sized systems could end up costing differently. Some of the things that may affect Solar PV system costs are:

  • Roof pitch: Generally speaking, the steeper the roof, the more careful people will have to work. Roofs with a steep pitch often proceed slowly and cautiously, adding time to the project. This can increase labor costs for solar panel installation and affect the total installation cost.
  • Roof material: Mounting mechanisms differ based on the construction of the roof type. For example, the IronRidge mounting mechanism we typically use on shingled roofs will not work on metallic roofs. Vice versa, S5 clamping used for metal roofs does not work on shingles. These differences can change the pricing of a system depending on how difficult it might be to install and match your particular system to your roof material.

How does Roof Type Change the Cost of Solar Panels?  

Your roof type matters when pricing out the total roof-mounted solar panels cost. Shingle vs. Metal vs. flat EPDM can affect solar mounting hardware and thus prices.

  • Size of system: Typically, the larger the system, the larger the inventory cost and the longer it takes to install it. Both mechanical and electrical crews will spend more time on site on a larger system than a smaller one, and therefore the labor costs go up in addition to increased hardware costs. A larger system typically means a higher solar power system cost but potentially lower cost per watt!
  • Length of electrical runs: If a Solar PV system is installed next to the incoming mains, the length of conduit runs will be small and will take less time. If a roof is utilized far away from incoming mains, the cable and conduit runs will be a lot longer and take longer to install. This increases labor and material costs and adds to the total solar panel cost. The same goes for trenching. If a ground-mounted solar system is installed, trenching can add significant time, labor and expense to a project, thereby increasing the solar panel installation cost.
  • Solar PV Technology: There can be a marked difference in system costs when using a completely different technology. For example, using a SolarEdge power-optimizer-based system vs. an Enphase micro-inverter-based system may affect pricing. Different Solar PV architectures have different component requirements and different installation guidelines, which can affect the pricing of components and labor required to install. Installation cost can therefore change if a different technology is desired.

How to Choose Between Power Optimizers and Micro-inverters

Different types of solar technologies also have different types of production, reliability and maintenance concerns. The age-old argument of power optimizers vs. micro-inverters will never end. A power optimizer and micro inverters are types of converters that connect to each solar panel and help improve the efficiency of your solar panels.

Both converters will optimize the performance of individual solar panels, especially on roofs that experience shading during the day. However, understanding key differences such as price, warranty, and maintenance will help determine the right choice for your solar panel project.

What are Other Solar Panel Cost Considerations? 

There are a few other considerations when determining the cost of your solar system:

  • Financial Incentives available: Different areas and regions have different incentives available. Different utility companies have different incentives that they offer. For example, Duke Energy has a rebate available right now. Local municipal generating facilities such as the Town of Apex do not. All of this can affect your total solar panel cost.
  • Rooftop vs. ground mount vs. stand-alone structure mount: Where the Solar PV array is installed can dramatically influence solar panel cost. Each option comes with its pros and cons. Rooftop installations must follow different design and installation considerations from stand-alone structures, which have different considerations than ground mount systems. Depending on your preference, ground solar panels carry different costs and can affect the prices of solar panels.

Are Solar Panels Worth the Investment?

In the last decade, the price of solar panels has fallen by approximately 60%. They can help you save on your monthly utility costs, and you can even sell any excess energy your solar panels produce back to utility companies using net metering.

Solar incentives in North Carolina also make it a worthwhile investment as the state tries to encourage more homeowners and businesses to turn to clean energy. The federal and state incentives you can benefit from include:

  • Solar Investment Tax Credit (ITC): The ITC will provide a 30% tax credit to residential and commercial solar installations through 2032, helping you save on what you owe the federal government for your new solar system. In 2033, the ITC drops to 26% and in 2034, it drops to 22%.
  • Property Tax Abatement for Solar Electric Systems: This tax abatement exempts 80% of the value of your solar system from your property tax. Homeowners with residential systems can also potentially see a 100% percent abatement, reducing the amount they pay yearly in property taxes. These tax savings help homeowners and businesses who want to invest in solar save on many of the associated costs.
  • Net Metering: North Carolina has a net metering policy that requires investor-owned utilities to credit you for the excess energy your solar systems produce, and you’ll receive full retail value for the extra solar energy.

You can also see if your utility company, city or county offers any additional incentives. For example, the Fayetteville Public Works Commission (PWC) Community Solar program offers monthly credits based on the number of installed panels on a residential or commercial property. With these various incentives, solar panels as a worthwhile investment for businesses and homeowners alike.

Which Solar Panel System is Best for My Project? 

Different solar panels have different performance ratings. Not all panels are suitable for all applications. Contact one of our sales consultants for an unbiased opinion on what solar panels will work best for your project. The following sections will give you a brief overview of the various options you have when choosing solar panels. 

  • Household electrical demand: This ties back to system size. The more you prefer to offset your electrical usage, the larger the Solar PV system needs to be and the more the costs will be for both labor and material.
  • Choice of solar panels: Different solar panels come in different efficiencies and sizes. Typically the higher the production per unit area, the higher the solar panels cost. This can affect the pricing of the system. In certain situations, if you have minimal roof space, you might want panels with the highest specific output. This system might have a different solar panel cost than a system that utilizes slightly lower efficiency modules because roof space is not at a premium. Recently, solar panel tariffs have bumped up pricing for all solar panels. In addition, different solar panels are produced in different areas of the world and carry different warranties. All of these factors can affect solar panel prices.
  • Off-grid vs. battery backup system vs. grid-tied systems: We consider your needs and your unique energy profile to determine if your system design should be entirely off the grid, grid-connected with a backup battery or just grid-connected. Every system has special needs, such as different components and varying code requirements, all of which affect the overall price. Even systems of the same size can have a wide variance in their pricing due to their system type. For example, a system that’s 10kW and grid-connected would cost less than a system the same size with a battery backup system. Adding the battery and additional labor and expertise required can significantly increase costs.
  • Permitting, inspections & interconnections: Based on the area where you live, and the utility that serves you, the costs associated with permitting, inspections and interconnections can vary widely. Different cities have different requirements for permitting. Similar different utilities have different rates for interconnection applications. All of this brings variability into pricing.
