40KW Solar System

A 40kW solar system offers an ideal solution for individuals or businesses interested in adopting sustainable energy. With the ability to produce around 40 kilowatt-hours (kW) of energy daily, this system is well-suited to meet the energy demands of larger households or medium-sized businesses. Let’s explore the details to see if a 40kW solar system aligns with your energy needs and explore the customizable options available to fit your specific requirements.

Is a 40KW Solar System the Right Choice for You?

A 40kW solar system may be the ideal choice if:

Your property’s monthly electricity usage falls between 1,200–1,600 kW.
You’re looking to reduce or eliminate your monthly energy bills significantly.
You have enough roof or land space for solar panel installation.
You’re ready to invest in energy independence while enjoying significant long-term financial benefits.

A 40kW solar system is ideal for larger homes, medium-sized businesses, or farms with consistent energy demands. Additionally, if your system generates more electricity than you use, net metering allows you to return excess power to the grid, potentially earning credits or additional savings!

Solar System Components

Understanding the components of a 40kW solar system gives you a clear picture of how they work together to deliver reliable, sustainable energy.

Solar Panels

Solar panels are the core of your 40kW solar system, transforming sunlight into electricity you can use. Based on the panel efficiency and the sunlight available in your region, reaching a 40kW capacity usually requires 40–50 high-performance panels. We take pride in offering American-made solar panels, supported by our Triple 10 Warranty, ensuring exceptional quality and dependability.

Inverters

Inverters are an important part of your solar system. They convert the direct current (DC) energy produced by solar panels into alternating current (AC) electricity, which powers your home or business. Modern inverters also include real-time energy monitoring, helping your system run at peak performance. We install trusted brands like Sol Ark, Solar Edge, and Tesla inverters to deliver reliable and efficient results.

Meters

Smart meters track the energy produced by your grid-tied or hybrid solar system and measure how much electricity you use or send back to the grid. They are key to taking advantage of net metering, which lets you earn credits for any surplus power you return. Additionally, a production meter is required to calculate and sell Solar Renewable Energy Credits (SRECs), giving you the chance to earn extra income from your solar system.

Batteries

Batteries are essential for both off-grid and hybrid solar systems. In off-grid setups, they store energy to power your home or business so you can have power at night. In hybrid systems, batteries act as backup power during outages and support energy needs after the sun goes down. Their flexibility makes them a key component for achieving greater energy independence.

Racking System

Whether you use a roof-mounted or ground-mounted solar system, a strong and dependable racking system is essential for keeping your panels securely in place. Our in-house designed Tough Trac system provides outstanding durability and reliability. With built-in wire management for better organization, Tough Trac is an excellent choice for mounting solar panels effectively.

Solar Panel FAQ

A 40kW residential solar system can last 25 to 30 years or more, depending on the quality of the components and regular maintenance. Solar panels are built to perform efficiently over decades, with warranties often covering 25 years and a slow output degradation of about 0.5% annually. Inverters, however, might need replacement every 10-15 years, and batteries, if included, usually last 10-15 years for lithium-ion or 3-5 years for lead-acid. Proper maintenance, such as cleaning the panels and ensuring all parts function well, is crucial in maximizing the system’s lifespan. With the right care, a 40kW solar system can provide reliable and cost-effective energy for decades, making it a smart long-term investment.

Solar panels make electricity using sunlight, whether direct or filtered through clouds. Although their efficiency may be lower on cloudy or overcast days compared to bright, sunny conditions, they still generate power, providing a steady electricity supply. This means your system keeps working and providing energy, no matter what the weather is like.

Reliable Renewable Energy: Solar power is an endless, eco-friendly energy source that provides a dependable solution for the future.
Reduced Energy Expenses: By producing your own electricity, you can drastically lower or even eliminate your monthly power costs.
Environmentally Friendly Choice: Solar energy is an environmentally friendly choice that avoids fossil fuels and helps lower greenhouse gas emissions.
Increased Home Value: According to a Zillow study, adding a solar system can increase a home’s value in Pennsylvania by as much as 4.1%.

A grid-tied or hybrid solar system for your home lets you send surplus electricity back to the utility grid through net metering. With this setup, any extra energy you generate earns credits on your account, which can be used to offset the electricity you consume from the grid. These credits can help reduce future energy bills, making overall electricity costs more affordable.
