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 number of panels needed depends on your location and roof size.

Most states have a solar production ratio of 1.3 to 1.6, which means an 8kW system produces 30% more energy, or 10,600 kWh annually on average. 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.

Where you live is a significant factor when estimating how many solar panels you need to power your house. Regions with less sunlight require larger systems to produce 100% of their energy needs.

Using the map below, take the number written in your shaded region and multiply by the estimated size of your system in kW. Then, multiply this number by 0.78 to account for inefficiencies and energy conversion losses.

For example, let's say you live in Texas with a score of 1700, and you believe you'll need an 8 kW system. This formula calculates a good estimate on how much electricity (kWh) your 8 kW system will produce annually.

1700 × 8 kW × 0.78 = 10,608 kWh

Below are the rough calculations which estimate the system size needed in each region to produce 11,000 kWh for the average home.

How Much Does One Solar Panel Cost?

One 150 to 300-watt solar panel costs $112 to $450 on average, or between $0.75 to $1.50 per watt depending on the type of panel, energy-efficiency rating, and size. Solar companies that purchase in bulk typically spend $0.75 per watt, whereas homeowners spend $1 per watt.

Most distributors only sell solar panels to local contractors at bulk wholesale prices. Hiring a solar installer will drastically reduce your overall equipment costs. These prices are for the panels only, additional fees for installation includes inverters, batteries, mounting hardware, wiring, and more.

Solar Panel Lease Cost

A solar panel lease costs $100 per month on average, with most spending between $50 and $250 per month depending on their location and energy needs. Leasing solar panels is cost-effective and typically saves $50 to $100 per month on your electricity bills with little to no down payment.

Solar leasing companies are responsible for the installation and maintenance fees for the duration of your contract. If you decide to move, expect to pay additional charges to end your leasing agreement because transferring the lease to another buyer can be difficult.

If you own your solar system outright that generates 100% of your power, the monthly cost is less than $10 per month for minor grid-tied connection fees. An off-grid system has no monthly costs other than general maintenance.

Tesla Solar Roof Cost

A Tesla solar roof costs $22 to $45 per square foot, which includes the solar roof tiles, a Powerwall, roof and site repairs, and complete system installation. A 9.45 kW solar system installed on a 1,800 square foot roof costs between $39,600 and $81,000.

On average, solar shingles cost up to $8,000 more than installing a new roof with traditional PV solar panels. Glass-faced solar shingles mimic the appearance of a tiled roof and cover more surface area than mounted PV panels to catch more sunlight.

Solar tiles have a lower efficiency rating in producing electricity. They may not last as long as PV panels because their design doesn’t allow much room for ventilation, which can lead to overheating.

Commercial Solar Panel Cost

A 10 kW to 2 MW commercial solar panel system costs $1.83 per watt before any tax rebates or incentives. Larger fixed-tilt or one-axis tracking utility-scale systems greater than 2 MW cost $1.06 per watt on average.

Commercial solar installation costs for small and mid-sized businesses range from $43,000 for a 25 kW system up to $175,000 for a 100 kW system. Businesses recover about 45 percent of solar panels costs within the first year through tax credits and rebate programs.

Commercial Solar Panel Cost
System SizeAverage Cost Before Tax Credits
25 kW$43,500 to $56,000
50 kW$87,500 to $113,000
100 kW$175,000 to $225,500
250 kW$437,000 to $563,500

Are Solar Panels Worth It?

Solar panels generate electricity approximately 30% cheaper than utility electricity in most locations, making them worth it over their lifetime. What makes solar more affordable is the 30% federal solar tax credit and state incentives.

The average residential electricity rate from utility companies is 13.19 cents per kWh, depending on where you live. An average 8 kW solar system costs $15,000 and generates 11,000 kWh annually or $880 to $1,100 worth of energy. Over the lifetime of the solar panels, this equates to 8 to 10 cents per kWh, which makes solar panels worth it after getting through the hefty upfront cost.

Solar Panel Installation Cost Factors

The cost to convert a house to solar power depends on your location, energy needs, type of solar panels, inverter and equipment options, permits, inspection, tax credits, and labor costs.

Use the national averages in the following table to calculate a cost-benefit analysis for solar PV installation.

Labor Costs To Install Solar Panels

The average labor cost to install solar panels is $0.27 per watt, or around 15% of the total cost of your system. A standard 6 kW system with 20 to 25 panels costs about $1,600 for solar installation labor before applying the 30% federal solar rebate.

Labor costs increase if your home has multiple stories, skylights, dormers, or a problematic 45° roof pitch. Contractors may need to design a unique system to make sure the panels receive enough sunlight to be efficient.

Solar Equipment Options

When installing your new solar system, you can choose between options such as on-grid vs. off-grid backup power, three different panel material types, and three different mounting types.

On-grid vs. Off-grid Solar Power Systems

Storing energy off-grid requires spending 30% to 40% more, or around $15,000 on backup power supplies, charge controller, generator, batteries, and installation costs.

Types of Solar Panels

Solar panels are constructed from three different types of materials; monocrystalline, polycrystalline and thin film.

Types of Solar Panels
TypeEfficiencyDescription
Monocrystalline15% – 22.5%Monocrystalline panels are made from high-grade silicon and are the most efficient, meaning you'll need fewer panels to support your energy needs. Monocrystalline panels generate up to an industry record of 22.5% of sunlight into energy typically come with a 20 to 25-year limited warranty.
Polycrystalline13% – 16%Polycrystalline panels are more affordable than Monocrystalline because they're made from fragments of silicon, which have lower energy efficiency.
Thin-film11% – 14%Thin-film panels are the least expensive and typically last 15 years. The panels are layered with photovoltaic materials that take up more space and provides a lower efficiency.

Solar Panel Mounts

There are three different ways to mount solar panels, which affect the overall cost.

Solar Panel Mounts
TypeAverage CostDescription
Fix-mount$15Fixed-mounts are the least expensive and less efficient than other mounts because they are stationary and can't be moved to capture more sunlight. These mounts are best in states with consistent sunlight.
Adjustable-mount$50Adjustable-mounts generate greater energy efficiency because they can be tilted towards the sun to maximize energy production. They can also be tilted flat during storms to avoid wind damage. Adjustable mounts are more expensive but are optimal in regions with seasonal climates.
Tracking-mount$500 – $3,000Tracking-mounts automatically follow the position of the sun to produce up to 30% more solar energy in climates with little to no snow. Solar trackers are more expensive, and there is more maintenance and on-site preparation involved. Most professionals recommended buying additional panels instead.

Sometimes it’s cheaper to install solar panels on rails in your backyard, such as when your roof surface is too steep, if your roof is mostly in the shade, or if you do not have a roof facing south to catch the most sunshine.

Solar Inverter Cost

A 5 kW solar inverter for a home system costs $1,000 to $2,000 for a single-phase model, and $1,500 to $3,000 for a premium 3-phase model. Inverter prices depend on the size, quality, and features. An inverter converts the current from the panels into an electric voltage that’s compatible with your home.

Marketing and Sales

Larger companies tend to spend extra on advertising to attract more business. However, that cost is baked into their installation services, and you’ll find better prices from smaller, more localized solar contractors.

Federal Solar Tax Credits & Incentives

There are various tax breaks and tax incentives offered by the federal government, local governments, states, and utility companies. Also, low-interest solar loans and $0 down installations are making it easy to buy a solar panel system.

How Does The Federal Solar Tax Credit Work?

The federal solar tax credit allows you to deduct 30% of the total cost of installing a solar energy system from your federal taxes. The investment tax credit (ITC), applies to both residential and commercial solar systems without a limit. Those leasing solar panels are not eligible for federal tax credits.

Frequently Asked Questions

How Much Does A Utility-Scale Photovoltaic Array Cost?

A utility-scale photovoltaic array greater than 2 MW costs $1.06 to $1.36 per watt before applying for the federal solar tax credit. This equates to $0.04 to $0.06 per kWh after using the tax credit.

How Much Does DIY Solar Cost?

Installing solar as a DIY project is difficult, and will cost more because solar companies buy wholesale directly from the manufacturers. Also, each solar installation needs to pass an inspection, according to state and federal laws.

How Much Does Solar Energy Cost Per Year?

Purchasing a 6 kW system ($12,600) on a 5-year payment plan costs about $2,500 per year or $210 per month. Once you own the system outright, solar energy costs $100 to $150 per year for maintenance and inspections. Another option to convert to solar is a lease at $600 to $3,000 annually.

How Much Does A Small Solar Panel Cost?

A small solar panel typically costs $2 to $4 per watt for residential use. A small 25-watt panel costs $40, while a 200-watt portable solar panel with a power station and outlets costs $250 to $300. A 45-watt solar battery bank can charge laptops, phones, tablets, and other smart devices.

How Much Does A Solar Heating System Cost?

A solar water heater costs$3,000 to $9,000 with installation, depending on the type and size. Solar heating panels, or solar thermal collectors, are different from photovoltaic (PV) solar panels because they only capture heat. Solar heating systems can heat your water supply, your air, or both.

Tips For Hiring A Solar Panel Installer

When searching for reputable solar companies, always get at least three quotes in writing from both big and small contractors, ask plenty of questions, check their credentials, and don’t sign any agreements until after an on-site consultation.

Get Multiple Solar Quotes

Homeowners who shop around often pay 10% to 20% less with savings up to $5,000 by getting at least three solar quotes from competing companies. Always ask for an on-site evaluation and request a detailed price quote in writing. Be sure to check the online reviews from HomeGuide and Google.

The largest solar installers typically quote inflated prices based on their brand and reputation. Always compare bids from the national brands to local installers to be sure you get the best deal. It's not uncommon to save thousands of dollars from smaller solar companies.
