HOME / 2026 solar roof cost solar shingles vs. panels prices
As of January 2025, the average solar panel system costs $2.92/W including installation in New York. For a 5 kW installation, this comes out to about $14,608 before incentives, though prices range from $12,417 to $16,799. After the federal tax credit, the average price drops by 30%. You'll probably pay even less than what we show here.
One of the biggest cost factors for your solar panel installation is the size of the system you have installed. System size is measured in kilowatts (kW) and is determined by household energy consumption. The average cost per watt is $3.04, but larger systems often have a lower cost per watt.
Mounting system: This is what holds rooftop solar panels in place. Costs vary depending on the type of solar installation, but it generally costs between 7 and 20 cents per watt. Electrical wiring and hardware: This includes the wiring, switches and circuit breakers required to connect the solar panel system to your home's electrical system.
You'll pay an average of $14,608 to install a 5 kilowatt solar panel system in New York, before incentives. The federal investment tax credit (ITC) lowers that price by 30% of all your solar equipment and installation costs. Why trust EnergySage?

When discussing solar panels, the term “size” can be confusing because it refers to electrical capacity rather than physical dimensions. Solar panel size is measured in watts (W) and indicates how much electricity the panel can produce under standard test conditions.
Solar panel size directly affects: Choosing the right dimensions ensures that your system fits your space while generating enough electricity to meet your needs. Let's explore the most common solar panel size dimensions available today: 1. Residential Solar Panels These are the most popular panels for homes. 2. Commercial Solar Panels
The solar panel size directly affects how much power your system can produce, how many panels you need, and whether your available roof space can support the installation. Choosing the proper system is not only about the solar panel dimensions. You should also consider wattage, number of cells, layout possibilities, and energy consumption.
Solar panel size is the key metric of every installation. A standard solar panel size (physical dimensions) of a panel determines how many solar cells it contains, which in turn affects how much power it can produce. Large commercial solar modules pack more cells, so they outrun smaller portable models on any solar panel size chart.
Using these numbers, an average-sized 8-kilowatt residential solar system would cost between $21,900 – $26,400. Regional pricing differences, the system size, local installation costs, inclusion of home battery backup, and local incentives are other factors which affect the final cost.

Your state's averages matter more than national numbers, and factors like shading, roof complexity, and local incentive programs all play a role in your final price. The average cost of a 12 kW solar panel installation on EnergySage is $29,649 before available incentives.
The average 6-kW residential solar panel installation is $17,852 before incentives. Learn about cost factors, financing options, tax breaks and more.
