Is a 100 KW Solar Setup a Good Match for You?

A 100kWh solar configuration is ideal if:

Your energy usage ranges from 3,000 to 4,000 kilowatt-hours per month
You aim to lower your dependency on the grid or fully replace conventional electricity
You have ample open space, either on a rooftop or land, for panel installation
You’re looking to future-proof your property with sustainable energy production

This system meets the needs of multi-unit properties, manufacturing sites, or large farms. If your output exceeds what you consume, you may be able to feed the surplus back into the grid, earning credits or income through net metering programs.

Solar System Components

Understanding the components of a 100 kW solar system makes it easier to see how each part works together to generate consistent, renewable power.

Solar Panels

Solar panels are the core component of any solar power system, converting sunlight into usable electricity for a home, commercial facility, or agricultural operation. A 100 kW solar system typically produces between 12,000 and 15,000 kilowatt-hours per month, depending on your location, sun exposure, weather patterns, and overall system efficiency. Reaching this capacity usually requires around 250 to 300 panels, depending on the wattage of each individual panel. At Belmont Solar, we install durable, American made panels and back every project with our Triple 10 Warranty, covering energy production, equipment, and installation quality for ten years.

Inverters

Inverters are an essential part of your solar energy system because they convert the direct current produced by your panels into alternating current that runs the equipment and appliances in your home or business. Modern inverters often include built in monitoring tools, making it easy to view energy production and overall system performance in real time. At Belmont Solar, we use dependable inverters from respected manufacturers like Sol-Ark, SolarEdge, and Tesla to deliver long lasting, efficient performance you can count on.

Meters

Smart meters monitor the electricity your grid-tied or hybrid solar system produces, as well as the power you pull from or send back to the utility grid. They play a key role in net metering programs, which provide credits for surplus energy returned to the grid. If you plan to participate in Solar Renewable Energy Credit programs, a separate production meter is typically required to record your system’s total energy generation over time.

Batteries

Batteries are a key component of both off-grid and hybrid solar systems because they store excess energy generated during the day for use when sunlight is unavailable. In off-grid systems, they supply dependable power at all hours without relying on a utility connection. In hybrid systems, batteries act as a backup source, helping keep your home or business powered during outages or interruptions from the main grid.

Racking System

Solar panels installed on a roof or on the ground need a strong, reliable mounting system to keep them secure in all weather conditions. At Belmont Solar, we use our in-house engineered Tough Trac racking system, designed for lasting durability and structural integrity. It also includes built-in wire management to ensure every installation looks neat and performs efficiently while maintaining a clean, professional appearance.

Our Solar Panel Installation Process

Take the first step toward solar by calling our team or filling out a quote request on our website. For the most accurate estimate, have your property address, a recent electric bill, and a rough budget range available. With these details, we can recommend the ideal system size for your energy goals and provide a clear overview of projected installation costs.

You will receive a free digital proposal that details the main components of your solar project. It will include estimated system costs, a projected return on investment timeline, and a tentative installation schedule. When you are ready to proceed, you can sign electronically and submit a deposit to move ahead with the next phase of the process.

Once the agreement is signed, our team takes care of the permitting process and any necessary paperwork by coordinating with local authorities. After securing all required approvals, we schedule the installation and send our technicians to begin work on your system. Following installation, we perform a thorough inspection to ensure your system is running efficiently and producing energy as it should.

Solar Panel FAQ

You can expect 25–30 years of steady performance, with most panels maintaining at least 90% of their original output even after two decades. Our systems are supported by a 25-year product warranty and a triple-ten warranty covering labor, hardware, and performance.

Yes. Even on cloudy or snowy days, panels absorb scattered light and continue producing power, though output will be reduced compared to sunny conditions.

Endless Energy Supply: Tapping into solar power gives you access to an energy source that never runs out. Unlike fossil fuels, sunlight is freely available every day, making it one of the most reliable and sustainable options for homeowners looking to take control of their energy needs.
Lower Monthly Power Bills: By producing your own electricity, you can significantly reduce what you owe the utility company or even eliminate your monthly bill altogether. Over time, this leads to substantial financial savings, especially as electricity rates continue to rise.
Eco-Friendly Power Production: Solar systems operate without burning fuel or emitting pollutants, which helps reduce your home’s carbon footprint. Choosing solar is a smart step toward cleaner air and a healthier planet.
Boosted Property Value: Adding solar panels doesn’t just help your wallet, it can increase your home’s resale appeal. A Zillow study found that homes equipped with solar energy systems in Pennsylvania could sell for up to 4.1% more than similar homes without solar.

If your home is equipped with a grid-tied or hybrid solar setup, any surplus energy your system generates can be sent back to the utility grid through a process called net metering. Instead of going to waste, this excess power earns you credits that are applied to your future electric usage. These credits help reduce your overall utility costs, allowing your solar investment to continue saving you money month after month, even on cloudy days or at night when you’re drawing energy from the grid.
