Residential solar panels are typically warrantied for 25–40 years, with many continuing to produce energy well beyond the warranty period with minimal degradation.
The process starts with a site analysis and a custom system design. Once approved, permits are obtained and materials are ordered. Installation typically takes a few days to weeks, followed by inspection and utility interconnection. Our team handles everything from start to finish, including paperwork, project management, and post-installation support to ensure your system performs at its best.
Look for a solar company with extensive commercial experience, NABCEP-certified professionals, and a strong track record of successful installations. Make sure they understand local permitting, interconnection, and incentive programs. A good installer should provide clear timelines, strong warranties, and ongoing service and support.
Commercial solar can be financed through several models including cash purchase, solar loans, operating leases, and Power Purchase Agreements (PPAs). A cash purchase provides the highest ROI, while loans allow for low or no upfront cost and tax benefit retention. Leases and PPAs shift system ownership and maintenance to a third party, with fixed energy payments. Our team helps determine the most beneficial option based on your financial goals and tax position.
Yes, installing solar demonstrates a commitment to sustainability and corporate responsibility. It positions your business as a forward-thinking leader and can enhance your brand with environmentally conscious customers and partners. Solar also contributes to ESG (Environmental, Social, and Governance) goals, which are increasingly important to investors and stakeholders. Publicizing your solar adoption can also generate positive PR and marketing opportunities.
Commercial solar systems often increase the value of your property by reducing operating expenses and adding a reliable energy source. Buyers and tenants are attracted to properties with lower utility costs and sustainable features. In some markets, solar-equipped buildings can command higher rents or resale prices. Additionally, some jurisdictions offer property tax exemptions on solar improvements.
Yes, solar panels work in winter and even in snowy conditions. As long as sunlight reaches the panels, they will produce electricity. In fact, cold temperatures can increase panel efficiency slightly. While output may be lower due to shorter days and occasional snow cover, systems in northern climates like Minnesota still perform well year-round.
The average return on investment (ROI) for commercial solar ranges from 8% to 15% annually. Most businesses see payback in 4 to 8 years, after which the energy savings contribute directly to the bottom line. ROI is improved further by federal tax credits, accelerated depreciation (MACRS), and local rebates. A properly sized and maintained system can outperform many traditional investments.
Savings vary depending on energy usage, system size, and available incentives, but most businesses reduce electric bills by 30% to 90%. Over a 25-year lifespan, that can amount to hundreds of thousands of dollars. Additional financial benefits include tax credits, depreciation, and net metering credits. With rising utility rates, solar helps lock in energy costs for decades.
Commercial solar panels capture sunlight using photovoltaic (PV) cells and convert it into direct current (DC) electricity. An inverter then transforms that into alternating current (AC), which powers your facility. If your system produces more electricity than you use, the surplus can be sent back to the grid, often resulting in utility bill credits through net metering. This process reduces reliance on the utility and offers long-term financial savings.
Monocrystalline panels are often the best choice for commercial applications due to their high efficiency and long lifespan. They perform well in both high- and low-light conditions and take up less space per watt. Polycrystalline panels may be more affordable but require more space and have lower efficiency. The best option depends on your space, budget, and energy goals.
Commercial solar provides lower electric bills, protection from energy price increases, and tax savings through federal and state incentives. It also improves your company’s sustainability profile and can increase property value. Many customers and partners prefer doing business with environmentally responsible companies. Over time, solar becomes a reliable and predictable source of savings.
The number of panels required depends on your building’s energy consumption, roof space, and panel wattage. For example, a business using 100,000 kWh annually might need a 75–100 kW system, or approximately 250–300 panels. We conduct a detailed analysis of your energy bills and facility layout to recommend the right system size. Our goal is to design a system that matches your financial and energy goals.
A commercial solar system is a complete energy solution that includes solar panels, inverters, mounting hardware, and often monitoring software and optional battery storage. It’s designed to reduce or eliminate a business’s electricity bill by generating power from sunlight. Systems can be roof-mounted, ground-mounted, or installed on carports or awnings. Battery storage can also be added to provide backup power and maximize savings.
The installation process begins with a site evaluation and engineering design tailored to your facility. After that, we handle permitting, order equipment, and install racking, panels, and inverters. Electricians connect the system to your building’s power and to the utility grid if applicable. After final inspections and approvals, your system goes live and begins producing clean energy.
Most commercial panels have an efficiency range of 18% to 21%, meaning they convert that percentage of sunlight into usable electricity. Higher-efficiency panels are often made from monocrystalline silicon and are ideal for space-limited applications. Lower-efficiency options like polycrystalline panels may be more affordable but require more space. Efficiency impacts both performance and cost over the long term.
In Minnesota, the average cost of a commercial solar system is around $2.90 per watt before incentives. A 100 kW system may cost about $290,000 but could be significantly lower after applying the federal Investment Tax Credit (ITC) and local utility rebates. Programs like Xcel Energy’s Solar*Rewards and commercial net metering improve financial returns. Additionally, Minnesota businesses may qualify for property tax exemptions and other benefits.
Commercial solar refers to solar energy systems installed on business properties or commercial buildings to offset or eliminate electric utility bills. These systems typically include panels, inverters, racking, monitoring, and sometimes battery storage. They are connected to the building’s electrical system and may also export power to the utility grid. Commercial solar helps businesses lower operational costs and improve environmental performance.
On average, a single commercial solar panel can produce between 1.5 to 2.5 kilowatt-hours (kWh) per day depending on local sun exposure, orientation, and weather conditions. Over the course of a year, this adds up to roughly 500 to 900 kWh per panel. The total system output scales with the number of panels installed. Energy production will vary slightly seasonally, with higher output in sunny months.
Most commercial-grade solar panels are approximately 6 feet by 4 feet and weigh between 40–60 pounds. Each panel typically generates 400 to 700 watts of electricity depending on its efficiency, physical size, and type. A 100 kW system may require 250 to 300 panels, depending on layout and panel wattage. The total space required depends on panel spacing, tilt, and the roof or ground area available.
Most commercial solar panels are warrantied for 25 to 30 years, and many continue to produce electricity beyond that with reduced efficiency. Manufacturers typically offer a 25-year performance warranty that guarantees power output above 80% of the original capacity. Inverters and other components may need replacement after 10–15 years, but maintenance costs are generally low. A well-maintained system can provide decades of reliable energy savings.
The full installation process typically takes 3 to 12 months from start to finish. This timeline includes engineering, permitting, utility approval, procurement, and actual installation. The construction phase itself may only take a few days to a couple of weeks depending on system size. Delays often stem from permitting or interconnection approvals, which vary by utility and municipality.
Commercial solar panels typically have efficiency ratings between 17% and 22%, with monocrystalline, N-type PERC, and IBC panels offering the highest performance. Efficiency refers to how well panels convert sunlight into electricity. While more efficient panels often cost slightly more, they can generate more power in limited space and may reduce the total number of panels required. Efficiency is especially important for rooftops with size or shading constraints.
The total cost of a commercial solar installation usually ranges from $200,000 to $350,000 for a 100 kW system, which is about $2 to $3.5 per watt. However, actual costs depend on system size, roof conditions, location, and utility requirements. Businesses in Midwest may also qualify for local incentives that further reduce the out-of-pocket cost. Federal tax credits (currently 30%) and accelerated depreciation (MACRS) can significantly lower the total investment.
Yes, commercial solar panels are a smart long-term investment for most businesses. They significantly reduce electricity costs, protect against rising utility rates, and may qualify for tax credits and depreciation benefits. Over the system’s 25–50 year lifespan, many businesses see a strong return on investment. In addition, solar can help you meet sustainability goals and boost your brand image.
One of the most common mistakes people make when using LEDs is not using them properly. LEDs are very efficient and will last a long time, but they need to be used correctly in order to get the most out of them. Make sure you follow the manufacturer’s instructions.
When choosing LEDs, look for lights that are labeled “dimmable” if you want to be able to adjust the light level. You should also look for lights that have a high color rendering index (CRI) to ensure that colors will look natural under the light. And be sure to choose an LED with a color temperature that’s appropriate for the room you’ll be using it in. For example, cool white LEDs are a good choice for kitchens and bathrooms, while warm white LEDs are better for living rooms and bedrooms.
LEDs are commonly used in task lighting, like under-cabinet kitchen lights, and accent lighting, like recessed and track lights. They’re also an excellent choice for outdoor lighting because they’re very durable and can withstand extreme temperatures.
LEDs can be more expensive than traditional light bulbs, but they last much longer and use less energy, so they will save you money in the long run. LEDs also produce a very bright light, so they may not be suitable for all applications.
LEDs, or light-emitting diodes, are a type of energy-efficient lighting. LEDs are the most energy-efficient type of lighting on the market today. They use about 75% less energy than traditional incandescent bulbs and last up to 25 times longer.
