5 Factors that Affect Your Total Solar Panel Installation Cost

Jul 15, 2022 12:12 PM ET

“How much does solar panel installation cost?” It’s a question we hear all the time and the short answer is that it varies. There’s no one-size-fits-all approach to solar installation.

The cost of your solar project is based on factors like:

  • How many solar panels do you need to meet your energy/financial goals?
  • Would you like your panels on a roof or ground mounted?
  • What type/brand of panels and inverters would you like? (Consider biface panels, string or micro inverters, wattage per panel, etc.)
  • Do you want any add-on options such as energy storage batteries or an electric vehicle (EV) charging station?
  • What solar incentives (rebates, tax credits, renewable energy credits) are you eligible for?

If you aren’t sure about the answer to any or all of these questions, don’t worry! Installing a solar energy system seems complicated but it doesn’t have to be.

With the expertise of a recognized, turnkey solar installer like MOXIE, the process becomes clear and simple. Whether it’s your first contact with a sales representative or a question you have three years after installation, our in-house team will be there to give the straightforward guidance and education you need.

Here’s 5 key factors to consider when estimating the cost of a solar energy system:

1. How many solar panels do you need? 

This is tricky. It’s not about how square footage is or the acreage of your farm. Rather, it’s about what it will take to achieve your goals for installing solar.

Are you trying to offset your total energy consumption? Standardize some or all of your energy costs?

Whatever your goals are, it’s important to clearly define them because they will determine your total system size, which in turn will determine exactly how many solar panels you need.

2. Do you want rooftop panels or ground mount panels?

Most in-town homes have rooftop solar due to a lack of available ground space or the desire to keep as much usable ground space as possible.

Large farms and commercial businesses often have the space for ground mount arrays. However, we have done plenty of ground-mount installs for residential homes and rooftop installs for farms and businesses. It all comes down to the size/layout of your property and available space on all roofs.

MOXIE survey and engineer teams will help determine the most optimal panel placement based on daily sunlight exposure, roof dimensions. You’ll work with our experts to choose the mounting style and design of the final placement of your solar array.

3. What kind of panels and inverters will perform best for your situation?

There are many options when it comes to choosing solar equipment: monocrystalline panels, polycrystalline panels, black-framed panels, silver-framed panels, 335-watt panels, 350-watt panels, Q-Cell brand panels, Mission brand panels, string inverters, micro-inverters, HD wave inverters… the list goes on and on!

Then there’s racking and mounting hardware. Different types of equipment offer different performance capabilities and different price points. Our experts can explain your options and give recommendations on the best choice of equipment for your property and your budget.

4. Need any add-on options like storage batteries or EV charging stations?

Once you have a solar energy system, you own direct access to an endless supply of renewable energy. Because of this, it often makes sense to store and utilize this energy to its fullest potential.

Battery storage systems (like the Tesla Powerwall shown here) allow you to store excess solar energy to be used during a power outage or extra cloudy day. Investing in an electric vehicle and dedicated charging station will add to your upfront cost but pay off in the long run.

Not only will your electric bill plunge, but you can completely forget about paying for gas, oil changes, and spark plugs – forever!

5. How many solar incentives are you eligible for?

Often overlooked, local and federal solar incentives are an important part of calculating your final solar panel installation cost.

Of course, there’s a 22%  tax incentive for 2021. There are also many other solar incentives at the state and sometimes city level. These incentives could be immediate cash rebates, tax breaks, or even renewable energy programs that earn you money.

For example, in Illinois, residents with solar panels can earn money for producing solar energy through the state’s Solar Renewable Energy Credit (SREC) program. The value of all these incentives should be deducted from the cost of your system to reach your final solar panel installation cost.
