20 kW Solar System

Considering a move to solar? A 20 kW system is a powerful solution for large homes, small businesses, or properties with high energy demands. Depending on your location, sunlight exposure, and system setup, it can produce roughly 60 to 90 kilowatt-hours (kWh) of electricity per day. That kind of output is often enough to support energy-intensive households or smaller commercial operations. Keep reading to explore the benefits of a 20 kW solar system and find out if it aligns with your energy needs.

Is a 20 kW Solar System Right For Me?

A 20 kW solar system is an excellent choice if:

Your property uses between 2,400 and 3,600 kWh of electricity per month.
You want to significantly cut or completely offset your monthly energy costs.
You have enough roof or ground space available to support a large solar panel installation.
You’re aiming for long-term energy independence and want to protect against rising utility rates.

A 20 kW solar system is well-suited for large residential properties, small businesses, or farms with consistently high energy needs. If your system generates more electricity than you consume, the surplus can often be exported to the utility grid through net metering. This setup allows you to accumulate energy credits, which can be used to offset future electricity usage and help reduce your overall utility expenses.

20 kW Solar System Options

At Belmont Solar, we specialize in building custom solar systems that align with your unique energy needs. Below are the three primary 20 kW solar system options we offer:

Grid-tie Solar Systems

Stay connected to the utility grid while cutting back on your dependence on conventional energy sources.

Grid-Tied Solar

Hybrid Solar Systems

Take advantage of grid access and off-grid flexibility by adding battery storage, ensuring reliable backup power when you need it.

Hybrid Solar

Off Grid Solar Systems

An ideal choice for remote areas or if total energy self-sufficiency is what you’re striving for.

Off Grid Solar

Each system is carefully planned to match your unique energy requirements, site conditions, and financial goals.

Solar System Components

Learning about the parts of a 20 kW solar system helps you see how they function as a whole to produce steady, clean energy.

Solar Panels

Solar panels are the key element of any solar energy system, responsible for turning sunlight into usable electricity for your home, business, or agricultural operation. A 20 kW solar system typically generates between 2,400 and 3,600 kilowatt-hours (kWh) per month, depending on your location, weather patterns, and the efficiency of your equipment. To reach this capacity, you’ll usually need about 45 to 60 panels, depending on their individual wattage. At Belmont Solar, we install durable, American-made panels and protect each project with our Triple 10 Warranty, covering energy production, equipment, and installation quality for ten years.

Inverters

Inverters play a crucial role in your solar energy system by converting the direct current (DC) produced by your panels into alternating current (AC), which powers the devices and appliances in your home or business. Many of today’s inverters also offer real-time monitoring features, allowing you to track energy output and system performance with ease. At Belmont Solar, we install high-quality inverters from trusted brands such as Sol-Ark, SolarEdge, and Tesla to ensure reliable and efficient operation for years to come.

Meters

Smart meters track both the electricity your grid-tied or hybrid solar system generates and the amount of power you draw from or return to the utility grid. They are essential for net metering, which allows you to receive credits for excess energy sent back to the grid. 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 over time.

Batteries

Batteries play a vital role in both Off-Grid and Hybrid solar systems by storing excess energy generated during the day for later use. In Off-Grid configurations, they provide a consistent power supply around the clock. In Hybrid setups, batteries serve as a backup solution, keeping your home or business running during outages or disruptions to the main utility grid.

Racking System

Roof-mounted or ground-mounted solar systems require a durable and secure racking structure to hold panels firmly in place. At Belmont Solar, we rely on our in-house engineered Tough Trac racking system, built for long-lasting strength and stability. It also features integrated wire management to keep installations clean, organized, and efficient in both function and appearance.

Solar Panel FAQ

A 20 kW solar system is built to provide reliable performance over the long term, typically lasting between 25 and 30 years. Most panel manufacturers offer warranties ensuring their products will retain at least 90% of their original efficiency for 25 years. At Belmont Solar, we install high-quality, American-made panels from Solar4America, supported by a 25-year limited product warranty. For added assurance, every system we install also includes our exclusive Triple Ten Warranty, which covers workmanship, equipment, and energy production for ten years.

While solar panels operate most efficiently in direct sunlight, they are still capable of generating electricity under cloudy or overcast skies using indirect or diffused light. Although energy production may be lower than on bright, sunny days, your system will continue to supply power even when sunlight is limited.

Renewable Energy Source: Solar energy harnesses the power of the sun—a limitless, no-cost resource—offering a dependable and sustainable solution for powering your home or business.
Reduced Electricity Costs: Switching to solar can significantly cut your monthly energy expenses and, in some cases, eliminate your electric bill entirely, depending on your system’s size and energy usage.
Environmental Benefit: Solar power generates clean electricity without burning fossil fuels, helping to reduce greenhouse gas emissions and minimize your environmental impact.
Increased Home Value: Zillow reports that homes equipped with solar panels in Pennsylvania can see an increase in property value of up to 4.1%, making solar a valuable upgrade both financially and environmentally.

A grid-tied or hybrid solar system allows you to take advantage of net metering, which lets you feed unused electricity back into the power grid. When your solar setup produces more energy than you use, the extra power is credited to your utility account. These credits can then be applied to future energy consumption, reducing your overall electricity costs in the long run.
