8 kW Solar System

If you’re considering solar energy, an 8 kW system can be a smart choice for larger homes or small businesses with moderate to high electricity usage. Depending on your location and sun exposure, this system can produce roughly 27 to 40 kilowatt-hours (kWh) of electricity each day, enough to meet the needs of many U.S. households. Keep reading to learn more about what an 8 kW system includes and whether it aligns with your energy goals.

Is an 8 kW Solar System Right For Me?

An 8 kW solar system is perfect if:

Your property uses around 750-1,100 kWh of electricity monthly.
You want to decrease or eliminate your monthly electric bill
You have room for a solar panel installation on your roof or property.
You’d like to invest in energy independence and long-term savings.

This kind of solar setup is a great match for mid-sized homes, small commercial properties, or agricultural operations with steady energy demands. Suppose your system produces more electricity than you consume. In that case, the surplus can usually be sent to the grid through net metering, allowing you to lower your utility costs or accumulate credits for future use.

8 kW Solar System Options

At Belmont Solar, we design custom solar systems to match your unique energy needs. Below are the three primary types of 8 kW solar installations we offer:

Grid-tie Solar Systems

Stay connected to the power grid while lowering your dependence on conventional energy sources.

Grid-Tied Solar

Hybrid Solar Systems

Merge the advantages of grid access and off-grid independence by adding battery storage for reliable backup power.

Hybrid Solar

Off Grid Solar Systems

An ideal setup for remote properties or if total energy independence is what you’re aiming to achieve.

Off Grid Solar

Each system is tailored to suit your energy needs, site conditions, and financial goals.

Solar System Components

Learning about the parts of an 8 kW solar system helps you see how they function together to provide steady, clean energy.

Solar Panels

Solar panels are the core of any solar system, turning sunlight into usable power for your home or business. An 8 kW system typically generates between 900 and 1,200 kWh per month, depending on your region’s solar exposure and the efficiency of your setup. To achieve this capacity, you’ll generally need between 16 and 24 panels, based on the wattage of the panels used. At Belmont Solar, we install high-quality, American-made panels and back every project with our Triple 10 Warranty, covering workmanship, equipment, and energy production to ensure long-term value and reliability.

Inverters

Inverters play a vital role in your solar power setup by changing the direct current (DC) produced by your panels into alternating current (AC), which powers your home’s appliances and devices. Today’s inverters often come with real-time monitoring features, so you can easily track your system’s energy output and efficiency. At Belmont Solar, we install trusted inverter brands like Sol-Ark, SolarEdge, and Tesla to ensure reliable and long-lasting system performance.

Meters

Smart meters track how much electricity your grid-tied or hybrid solar system generates, as well as how much you consume and return to the utility grid. They’re essential for taking advantage of net metering, which allows you to earn credits for any excess energy you supply. To qualify for Solar Renewable Energy Credit (SREC) programs, you’ll also need a dedicated production meter that measures your system’s total energy output.

Batteries

Batteries play a critical role in both Off-Grid and Hybrid solar setups by storing excess energy generated during the day for use at night. In off-grid systems, they provide around-the-clock power, while in hybrid systems, they serve as a reliable backup during grid outages, keeping your home powered even when the utility goes down.

Racking System

No matter if your solar system is mounted on the roof or installed on the ground, a secure and durable racking structure is essential to support your panels. At Belmont Solar, we use our in-house designed Tough Trac racking system, built for long-lasting strength and stability. Tough Trac also features built-in wire management, ensuring a tidy, professional finish that enhances both the performance and appearance of your installation.

Our Solar Panel Installation Process

Start your solar journey by giving us a call or submitting a quote request through our website. To provide you with the most accurate estimate, it’s helpful to have your address, a recent electric bill, and a rough idea of your budget ready. This allows us to recommend the right system size and give you a clearer picture of installation costs.

You’ll get a free digital proposal outlining the key details of your solar installation. This includes projected costs, an estimate of how long it will take to recoup your investment, and a preliminary timeline for the work. When you’re ready to move forward, just sign electronically and submit a down payment to start the process.

Once the agreement is in place, we coordinate with local authorities to take care of all permitting and paperwork. After receiving the necessary approvals, we’ll schedule the installation and have our team come out to begin setting up your solar system. When the work is finished, we’ll perform a thorough system check to ensure everything is functioning correctly and producing energy as intended.

Solar Panel FAQ

An 8 kW solar system is built for long-term performance, typically lasting between 25 and 30 years. Many panel manufacturers guarantee that their products will still operate at 90% or more of their original capacity after 25 years. At Belmont Solar, we install reliable, American-made panels from Solar4America, which include a 25-year limited product warranty. For added assurance, all of our installations are protected by our exclusive Triple Ten Warranty, covering system components, energy production, and workmanship for ten years.

Solar panels operate most efficiently under direct sunlight, but they’re also capable of generating power from indirect or diffused light—like the kind found on cloudy or overcast days. While energy production is lower in these conditions, the system will still continue to generate electricity even when the skies aren’t completely clear.

Renewable Energy Source: Solar power relies on sunlight, a limitless and cost-free resource, making it one of the most reliable and sustainable energy options available today.
Reduced Electricity Costs: Producing your own electricity with solar can significantly cut your utility bills—and in some cases, eliminate them—based on how much energy you use and the size of your system.
Environmental Benefit: Because solar systems don’t depend on fossil fuels, they generate electricity without releasing greenhouse gases or other pollutants, making them a cleaner alternative for the environment.
Increased Home Value: Zillow research suggests that homes in Pennsylvania with solar systems can gain up to 4.1% in property value, offering both environmental and financial advantages.

By installing a grid-tied or hybrid solar system, you can take advantage of net metering—a program that enables you to return surplus electricity to the utility grid. When your system produces more energy than you use, those extra kilowatt-hours are recorded as credits. These credits can then be applied to future electricity consumption, reducing your overall energy costs.
