The Solar Market Insight (SMI) is a quarterly report published by the Solar Energy Industries Association (SEIA) and Wood Mackenzie. The SMI provides detailed information about the US solar industry, which includes installed costs by market segment: residential, commercial, and utility scale.
The US installed 1,641 megawatts (MW) of home solar capacity between January and March 2023.
The average cost of home solar systems was $3.28 per watt in Q1 2023.
Last year was an excellent year for residential solar power in the US. More than 700,000 homeowners installed photovoltaic (PV) systems, with a combined capacity of 5,860 MW.
In other words, the US installed around 1,465 MW of home solar power per quarter. 2023 could be an even better year for the solar industry if installations continue at the current pace.
The average price of home solar systems has increased by 7% between June 2022 and June 2023. One year ago, the SEIA reported an installed cost of $3.07 per watt. However, prices have decreased slightly with respect to Q4 2022, when the SEIA reported a cost of $3.30 per watt.
How Much Does a Home Solar System Cost in July 2023?
The following table provides the estimated cost of solar PV systems from 4 to 10 kilowatts (kW), which is a common size range for homes. Regardless of the installed capacity, you get a federal tax credit equivalent to 30% of project costs.
Spray Foam Insulation, also known as Spray Polyurethane Foam (SPF), is considered one of the best insulating, and air sealing, and weatherization materials on the market today. In fact, there is no other material available that comes close to providing the insulation and weather-proofing benefits of SPF.
Spray Foam (SPF) Insulation Overview
Open Cell Spray Foam Insulation Application in between the Wall Cavities.
SPF is frequently used to insulate and air seal residential, commercial, and industrial buildings. A professionally done spray foam insulation application can completely insulate your home including walls and wall cavities, basements and crawlspaces, roof deck and attic space, as well as help seal those key spaces from the air leaks and moisture penetration.
Did you know? Home insulation upgrades including SPF can result in a more comfortable, healthier, and more energy-efficient home, with an average annual reduction of 15% in home heating and cooling costs. Such an upgrade can be especially consequential for homes located in areas that experience extreme temperatures, whether it be the blistering cold of winter or the sweltering heat of summer.
Once cured and hardened, spray polyurethane foam can actually help strengthen the walls and the roof structure of a house, as well as help protect against moisture, dust, pollen, insects and mold.
Spray Foam can be used in a variety of applications, not just for insulation, and will self-adhere to almost any material including concrete, wood, steel, and most existing roofing materials when spray foam is used as a roofing material for Spray Polyurethane Foam (SPF) roofing applications.
Fun Fact: SPF can even be used to create a tapered roofing system, in which the pitch or slope of the roof is created by the insulation itself!
Before you contact a professional, it’s always a good idea to know something about SPF and which type will best suit your project.
Beyond the Basics:
In this guide, we will answer the following questions:
Cost to Install Spray Foam Insulation: Closed Cell vs. Open Cell Foam
The national average cost to install spray foam insulation can range between $1.00 and $3.00 per square board foot (1 inch thick) of SPF insulation installed.
For example, to install 1,500 square board feet of one inch-thick Closed-Spray foam insulation in the attic space of a house, it will cost between $1.50 and $2.50 per square board foot, on average, with the total project cost ranging from $2,250 to $3,750, fully installed.
With the Open Cell Foam (a less-costly option), your cost will likely range between $.5 and $1.50 per square board foot (1 inch thick), depending on the size and type of application, accessibility, and your home’s location.
Note: The average cost per square board foot will largely depend on the type of spray foam insulation being installed (closed-cell foam is more costly than open-cell foam), project size (the larger the project the less you will generally pay on per square board foot basis for spray foam), your home’s location (local real estate market and demand for remodeling services), ease of access, and other project-specific variables.
A typical asphalt shingle roof can cost anywhere from $4.00 to $9.50 per square foot to install, depending on the choice of material, roof difficulty, project scope, and your home’s location. – Undoubtedly, that is a rather wide range for composition shingles.
In this guide, we will explore the average cost to shingle a roof on a typical house. We will cover six main types of roofing shingles, including composition or asphalt, metal, cedar, synthetic or rubber shingles, stone coated steel shingles, and the new GAF Timberline solar shingles. Armed with the latest prices and pros and cons of each system, you can decide what type of shingle is best for your home and budget. Let’s delve in.
