Commercial Solar： What You Need to Know About

Commercial solar sits between the more familiar residential and utility-scale sectors, offering a flexible range of options for businesses of all sizes. As more financing options, like power purchase agreements (PPAs), become available, the adoption of commercial solar is set to rise. Commercial solar projects have become a powerful tool for businesses, and nonprofits to cut energy costs and promote sustainability.

What Is Commercial Solar?

Commercial solar is simply using solar energy to power businesses rather than homes. It’s a clean and renewable source of energy that helps companies save on their electricity bills while being environmentally friendly. Businesses of all sizes—from local shops to large corporations, schools, and even government buildings—can benefit from installing solar panels. Because of its wide range of uses, it’s often called “C&I solar,” which stands for commercial and industrial-scale solar.

Why Should My Business Consider Commercial Solar?

One of the biggest benefits is the significant reduction in electricity bills. By generating your own solar power, you can offset a large portion of your energy costs, with businesses often reporting savings of 50% or more.

In addition to lowering current bills, solar systems protect your business from future energy price hikes. This allows for more predictable energy expenses and can lead to considerable savings over the system’s lifespan.

According to Solar Thermal Magazine, installing solar panels can increase your property value by around 10%, adding long-term value to your commercial building and making it more appealing to future buyers or tenants. These findings highlight the practical advantages of integrating solar energy into business operations for business owners considering such investments for long-term energy solutions.

What Does Commercial Solar Installation Consist Of?

Commercial solar installations typically involve multiple stages, starting with site assessment and energy audits to determine the best placement for solar panels and the energy needs of the business. The system is then custom-designed based on these findings, with engineers creating a solution that fits the available space, like rooftops or ground areas. After obtaining the necessary permits and approvals, the installation of panels, inverters, and wiring begins, which connects the system to the existing electrical grid. Once installed, the system undergoes testing and inspections before being activated. Many commercial systems also include monitoring and maintenance options to ensure long-term performance. Some companies may opt to include battery storage systems for added energy resilience, especially for critical infrastructure.

How Much Does a Commercial Solar System Cost?

The cost of commercial solar systems can vary widely depending on the size of the system and the location of the installation. On average, commercial installations cost around $1.83 per watt, meaning a mid-sized system (100 kW) could cost between $180,000 to $250,000. Factors influencing cost include the complexity of the installation, available government incentives (such as tax credits), and additional components like energy storage. The costs have been gradually decreasing over time due to advances in technology, but supply chain issues can cause fluctuations.

What Are The Benefits Of Solar Energy?

Solar energy allows businesses to become more sustainable in every way. Solar installations help businesses to manage their electricity expenses and carbon footprint. We will discuss the benefits of installing a commercial solar PV system below.

Cost Savings

While going solar benefits the environment, businesses are primarily drawn to it for long-term operational savings. Solar energy significantly reduces electricity costs, which can account for a large portion of a business’s overhead. Many companies report savings of 50-90% on their energy bills, and with rising utility rates, solar provides a stable, long-term solution for energy expenses.

Solar energy is becoming a more affordable and widely adopted option across industries, offering businesses the ability to generate their own power, rather than purchasing it from utilities. By installing a commercial solar system on-site, companies effectively become their own electricity providers, which can increase the value of their property.

Solar installations not only stabilize electricity costs but also offer a predictable revenue stream, as they shield businesses from fluctuating utility rates. Seen as a long-term investment, these systems typically require minimal maintenance, contributing to their cost-effectiveness over time. Though upfront costs may be a barrier, various incentives and financial benefits make solar energy a more feasible solution for large enterprises looking to reduce expenses and embrace sustainability.

Tax Incentives and Rebates

Various federal, state, and local incentives help offset the upfront costs of installing solar panels. For example, businesses can take advantage of the Investment Tax Credit (ITC), which offers up to a 30% rebate on the cost of solar installation, as well as the Modified Accelerated Cost Recovery System (MACRS) for depreciation benefits.

The Federal Investment Tax Credit (ITC) has been one of the most significant incentives in reducing solar installation costs over the past decade. Eligible businesses can offset a large portion of their system expenses by applying the ITC to their federal income taxes. However, certain institutions, such as religious organizations, schools, and other entities that don’t file annual income tax returns, are not eligible for this credit.

In cases where businesses don’t have substantial tax liabilities, alternatives like Tax Equity Financing or third-party ownership models can still allow them to benefit from the ITC. These options can help reduce the upfront costs of installing a photovoltaic (PV) system, making solar energy more accessible even without direct access to the tax credit.

Energy Independence

Businesses with solar installations can reduce their reliance on the traditional power grid, ensuring more consistent energy supply and protection from rising fossil fuel prices or power outages.

Companies with PV solar energy systems are less reliant on public utilities because they can generate their own clean electricity on-site. However, during blackouts, grid-tied solar systems often shut down for safety reasons if they can’t feed electricity back into the grid properly. To address this, many solar providers are integrating advanced systems with energy storage capabilities.

When paired with battery storage, a solar system can operate independently as a microgrid. This means that even during a power outage, the system can continue to generate, store, and use electricity, ensuring that businesses maintain operations without disruption. Having your own commercial solar PV system not only enhances energy resilience but also protects your business from the risk of grid failures.

Solar Energy Accomplishes ESG Goals

Switching to solar helps reduce a business’s carbon footprint by using clean, renewable energy. This not only contributes to environmental goals but also enhances the company’s reputation as a responsible and sustainable brand, which is increasingly important for customers and stakeholders.

One of the main reasons companies switch to solar energy is that it helps an organization achieve its social, environmental, and governance objectives. Going solar is not just about cost savings, even though it will probably show a financial benefit on a company’s balance sheet.

Solar power is a very efficient solution for businesses to achieve sustainability goals since it is a measurable and easily quantified green energy asset. Commercial solar energy reduces a building’s carbon footprint as soon as it starts operating; this process is known as immediate decarbonization.

Investing in commercial solar not only helps companies save money but also improves brand reputation and operational resilience. With long-lasting systems and minimal maintenance, businesses that go solar can enjoy decades of energy independence and stability.
