    How Many Solar Panels Do I Need?

    The average family uses 11,000 kWh per year and needs 26 to 33 solar panels to power the whole house. One solar thermal panel generates enough energy to power a hot water heater for a family of four.

    The total number of panels needed depends on your location, roof size, and energy needs. To calculate how many solar panels you need, look at your annual kWh (kilowatt-hours) usage on your utility bills and referenced the table and map below.

    Table based on 250 watt panels at average solar production ratios of 1.3 to 1.6.

    Your home’s location is a significant factor when estimating how many solar panels you need to power your house. Regions with less sunlight require larger systems to handle 100% of their energy needs.

    • Multiply the number in your shaded region by the estimated size of your system in kW.
    • Then, multiply the result by 0.78 to account for inefficiencies and energy conversion losses.

    For example, if you live in Texas with a score of 1700 and install an 8 kW system, your system will produce approximately 10,608 kWh annually:

    1700 × 8 kW × 0.78 = 10,608 kWh

    How Much Does It Cost to Go Solar, Anyway?

    It’s exciting to think about the savings you can get by switching to clean solar energy, but when it’s time to actually install solar panels on your roof one of the first questions is this: how much does it cost to go solar, anyway? Let’s take a look at the average price of solar in Colorado and what that means for different sized residential solar systems.

    Average Cost of Solar Panel Systems

    At Namasté Solar, we see home solar panel installation costs range from approximately 20,000 to 50,000 based on a variety of factors. The size of the solar panel system is the most heavily weighted factor in determining cost. The size of your recommended system is based on your electricity usage and is measured in kilowatts (kW). A properly sized solar panel system will maximize your savings and return on investment (ROI).

    Rather than FOCUS on the cost of your system, it’s best to look at the projected return on your investment. How much will you save over the life of your system? When compared to the cost of your current electricity bill, solar panels often show thousands of dollars in savings over their lifetime – sometimes paying for themselves twice over! That’s on top of the increase in home value and environmental benefits of solar.

    Beware Online Calculators

    Most online solar calculators are based on “average” homes and can’t accurately assess the cost and overall savings potential of solar for your specific home. We’ve checked many of them and found that they don’t provide accurate information, and in many cases are way off. Contact a local solar provider for a customized quote. It’s free and it’ll provide you with the most accurate information.

    There are a variety of ways to pay for your residential solar system, and your local solar company will help you find the option that’s best for you.

    How Much Do Solar Panels Cost in Each State?

    Solar panel costs can vary according to your state’s energy rates and access to solar technology. Check the table below to get an idea of what solar panels might cost you in your state.

    Solar Panel Cost Breakdown

    EnergySage estimates that the national average cost for a typical 6-kilowatt (kW, or 6,000 watts) residential rooftop solar system is roughly 20,650 before any federal tax credits or local incentives. Overall, you should expect to pay anywhere between 17,430 and 23,870, depending on your system size and location. The total cost of a solar system includes solar panel. which vary in price by brand and type, installation labor, and additional equipment. A solar installation company will charge a combination of labor costs and a price per watt for each solar panel. Based on a June 2023 report.

    Types of Solar Panels

    • Monocrystalline: The most popular solar panel on the market today, monocrystalline panels offer the highest efficiency rate, at an average of 24%. However, they are also the most costly. The average cost for monocrystalline solar panels is 450 to 450.50 per watt. Therefore, a standard 6kW system costs between 6,000 and 9,000.
    • Polycrystalline: Polycrystalline panels are a more cost-effective option up front. However, they feature a lower efficiency rate than mono panels, at an average of 20%. The average cost for polycrystalline solar panels is

      Other Factors to Consider About Solar Panel Costs

      In addition to the cost per watt for each solar panel, other factors influence the overall cost of a solar power system. We have listed some of the most critical factors for you below.

      Energy Needs

      Take note of your current cost of electricity. as switching to solar may or may not save you money on your energy costs. The larger your home and higher your monthly electric bill. the more benefits you are likely to see from switching to solar. A solar system can eliminate a homeowner ’s electricity bill in some instances.

      On the other hand, if you already have relatively low utility bills. you may not see enough savings to justify the expense of installing a home solar system.


      The location of your home plays a vital role in how much money solar panels can save you. Using data from the Centers for Disease Control and Prevention (CDC), the data analysis site Stacker determined that the following 10 states are the sunniest in the continental United States:

      Roof Type

      You can use a solar panel system even if you don’t live in these blue-sky states. Most solar panel installers use photovoltaic (PV) panels, which can absorb both direct and indirect sunlight. However, these solar panels generate the most energy on angled roofs that allow maximum sun exposure. On the other hand, a flat roof will require the construction of angled platforms, which will add to your labor costs and increase the overall cost of your solar system installation.

      Additionally, south-, west- or southwest-facing roofs get more sun exposure. For example, a home that experiences less shade and has a south-facing roof with a slope between 15 and 40 degrees will receive the most sunlight. Therefore, these homes receive and retain more solar energy. On the other hand, a home with trees around it or in a less sunny region, like the Pacific Northwest, may not save as much money as a homeowner in Arizona or California.

      Your roof’s age and structural soundness will also influence the overall cost of solar panel installation. Repairing your roof or upgrading your roofing material to support panels will come at an additional expense ahead of installation and affect your total cost.

      Solar Incentives

      Both state and federal governments provide solar incentives to help offset the up-front costs of switching to solar. Namely, the federal solar tax credit, or solar investment tax credit ( ITC ), plays a significant role in helping to make residential solar panels a better investment. This tax credit provides 30% off your total price of solar panel installation.

      Local incentives vary by state. For example, some states allow you to earn and sell credits for the electricity your solar system produces through a net metering program. Others offer solar rebates. We recommend using the Database of State Incentives for Renewables Efficiency to see what rebates and state tax credits you can receive.

      Payment Options

      Solar providers offer various payment methods that influence how cost-effective your investment in solar is. Here are the four payment options you can choose from with most solar companies :

    • Purchase: Paying for your solar system up-front is the most cost-effective payment method for a solar system. Not only will you avoid paying interest over time, but you will also be eligible to file for the federal tax credit at your next income-tax filing.
    • Solar Loan: Solar companies understand that not every homeowner is willing or able to pay for their system up-front. so they partner with a lending company to provide loan options. As with all bank loans, your interest rate will depend on your credit score.
    • Solar Lease: Some homeowners may elect to lease their solar panel systems. With this arrangement, the solar company still owns the system, and you pay a set monthly amount for the installed solar panels. This option is not as cost-effective over time as purchasing or financing your system, as you are not eligible to receive state or federal incentives. However, you avoid paying hefty up-front sums.
    • Power Purchase Agreement (PPA): A solar PPA lets you pay little to nothing for the actual installation of the PV system. Instead, you pay monthly payments to a utility company based on the energy generated by the system. Think of this as if you are paying for your usual electricity bill. As with a lease, you don’t own the system and are thus ineligible for tax incentives.

    .90 to 450 per watt, or 5,400 to 6, total for a 6 kW system.

  • Thin-film: Thin-film solar panels are less popular for residential solar systems. They tend to cost around

    Our Recommendation

    Residential solar panels help you cut both your electricity costs and carbon emissions. To ensure switching to solar is a sound investment for you, pay attention to your current utility rates. If you notice that your utility bill tends to be on the mid to upper end of your state’s average, you are nearly guaranteed to save money with solar in the long run.

    In addition, if you can purchase or finance your solar system. you are making a more cost-effective decision than if you lease or sign a PPA.

    We suggest using the tool below to see which solar installation companies service your zip code and get a sense of what a solar provider near you charges for installation.

    .70 to 450 per watt. That’s roughly 4,200 to 6,000 total for a 6 kW system.

  • Solar Panel Installation Cost

    Installation costs—including labor and permits—average around 25% of the cost of the solar panel system itself. So, for example, if you purchase a 6-kW monocrystalline solar panel system for 20,000, then a solar installation company will likely charge approximately around 25,000 for the system and the installation, combined. The installation of a larger system will naturally increase labor costs.

    Additional Equipment

    Residential solar systems also typically require a battery to store energy and an inverter, which converts the variable direct current (DC) output of your PV solar panel s into alternating current (AC). Most solar companies will include these components in your solar system’s design. However, if you request specific brands of inverters or batteries, they may come at a premium.

    Solar Panel Installation Cost

    Here’s an exciting number. The cost for residential solar panel systems has dropped a remarkable 61 percent since 2010. That’s according to the National Renewable Energy Laboratory’s (NREL) 2017 solar cost benchmark report.

    A solar panel system is comprised of many pieces. You might already know the cost of a solar panel system before and after tax credits, in broad strokes.

    Here’s an example on how we can breakdown solar panel cost and what it typically costs for installing a system.

    Current industry average cost = between 3 to 4 per watt

    Average size solar panel system = between 5 and 6 kilowatts (a kilowatt is 1000 watts)

    3.26 (per watt) x 5,000 (watts) = 16,300 per system (before the 30% ITC tax credit)

    But let’s get a little more granular. In the chart below, you can see that while the overall costs have gone down, the reduction comes mostly from hard costs such as solar panels themselves.

    Whereas the soft costs haven’t changed much, now typically accounting for around 64 percent of a new solar system.

    Let’s take a closer look at the breakdown of hard costs vs. soft costs associated with installing residential solar panels.

    Hard Costs for Residential Solar Panel Installation

    Think of hard costs in terms of hardware: the physical products installed to get your new solar panel system up and running.

    This is what you’ll pay for the solar panels themselves, inverters, solar mounting racks, a battery for storage, etc.

    Solar panels can account for about 25 to 30 percent of the total solar panel system cost.

    • A solar inverter, which can account for about 10% of hard costs
    • Solar mounting and electrical equipment, which can be another 10%

    Here’s a useful pie graph sourced from the National Renewable Energy Laboratory:

    See those “other” costs and installation? Those are soft costs, which we’ll address next.

    Solar Panel Installation Cost – Soft Costs

    Soft costs include administration costs for the company, customer acquisition and marketing, system design, permits and fees for connecting to the grid, and labor for installation.

    Here’s a soft costs breakdown from the Department of Energy.

    You’ll notice the percentages for each of these soft costs is smaller but, as they say, it adds up.

    In fact, the Solar Industry Information Association (SEIA) just released a report putting the number for soft costs at 68 percent!

    To some degree, soft costs are simply part of running a business. In order to keep their doors open, solar energy companies have to pay employees, attract new customers and make a profit.

    Soft Cost Reduction Solutions

    The Department of Energy’s Solar Energy Technology Office (SETO) launched an initiative called Sunshot in 2011. The goal is to put solar energy financially on par with other energy sources by the year 2020.

    Various permitting, entities and laws throughout various jurisdictions can slow down the process of solar installation and raise costs. Through systematizing and unifying solar, SETO is working to cut red tape and prices.

    They also fund research for new ways to streamline solar company operations. Better software and processes to help solar companies reach new customers and run more smoothly helps tame soft costs. Through these efforts, the savings can be passed on to solar customers.
