Why Should You Think About Solar For Your Business?
4 Benefits to Commercial Solar Installation
Save Money and Offset Electricity Bill
1. Saving Money with Commercial Solar for Businesses
One of the biggest advantages of commercial solar installation is the ability for businesses to significantly reduce long-term energy costs. By generating electricity onsite, solar for businesses helps offset monthly utility bills and protect companies from rising electricity rates. Instead of relying entirely on the grid, your business produces clean, renewable energy that powers daily operations.
Over time, these energy savings can add up to substantial financial benefits. Many businesses also qualify for federal incentives, tax credits, and accelerated depreciation programs that further improve the return on investment. With commercial solar installation, companies can lower operating expenses while creating predictable energy costs for years to come.


Start Creating Your Own Energy
2. Energy Independence
One of the key benefits of commercial solar installation is achieving greater energy independence for your business. By generating your own electricity onsite, solar for businesses reduces reliance on utility providers and protects your company from fluctuating energy prices and grid instability.
With a properly designed commercial solar system, your business can produce a significant portion of the power it needs to operate. This increased control over energy production helps stabilize operating costs, improves long-term financial planning, and ensures your business has a more reliable and sustainable energy source.
Solar Tax Incentive for Businesses
3. Tax Incentives for Commercial Solar Installation
One of the most attractive benefits of commercial solar installation is the availability of valuable tax incentives for businesses. Federal programs such as the Investment Tax Credit (ITC) allow companies to claim a significant percentage of their solar project cost as a tax credit, helping reduce the upfront investment required for solar for businesses.
In addition to the ITC, many businesses can take advantage of accelerated depreciation through programs like MACRS, allowing them to recover a large portion of the system cost in the early years of the project. These financial incentives make commercial solar installation a powerful strategy for lowering tax liability while investing in long-term energy savings.


Reduce Your Carbon Footprint
4. Support The Environment
Investing in commercial solar installation allows businesses to reduce their environmental impact while generating clean, renewable energy. By using solar for businesses, companies can lower greenhouse gas emissions and decrease reliance on electricity produced by fossil fuels.
Adopting solar energy demonstrates a commitment to sustainability and responsible business practices. With commercial solar installation, businesses not only reduce their carbon footprint but also contribute to a cleaner, more sustainable future for their communities.

FAQs About Commercial Solar
The environmental benefits from switching to solar are well-known already, however not many are aware that there are also excellent financial benefits that make commercial solar energy a lucrative investment too. There are several incentives and programs available that can assist with offsetting electricity and operation costs, so it’s clear to see why switching to solar energy can be extremely beneficial to a wide variety of businesses, such as agricultural, industrial or commercial.
Obviously using solar energy instead of normal electricity taken from the grid can hugely reduce the ever-rising electricity bills any business can incur. This can generate huge savings throughout the life of the installed solar system, which can make the business more competitive in the market. Across the USA and the whole world, electricity rates have been rapidly increasing as the years go by, much faster than predicted. Switching to commercial solar energy can guarantee your electricity rates will not hike up.
Larger than solar panels designed for residential use, photovoltaic commercial solar panels absorb the sun’s energy throughout the day, converting UV rays into direct current (DC) electricity. Most businesses run on alternating current (AC) electricity, so along with the solar panels, inverters are needed to convert DC to AC electricity for the building’s use.
Electricity bills can be reduced drastically with a commercial solar system designed to offset the energy a facility would typically consume with solar power, instead of relying on the utility for. Unless a commercial solar solution is specifically designed with an energy storage system to be fully independent, you will likely still receive a small bill from your utility. Although with solar offsetting use, businesses are more protected against a certain future of rising electric costs from your utility.
While it is possible to design a system that is separated from the grid with energy storage systems, it would cost significantly more to design that system with the safeguards, backups, and redundancy that the utility provides. A typical system is designed to tie-in to the grid, accessing utility power for when solar can’t generate electricity – like at night.
There are different ways to mount solar panels to commercial building rooftops. If needed, we work with your roofer or a certified roofer to seal any penetrations made to maintain the existing warranty. If your roof needs replacement, we work with the roofer to incorporate the solar system into the warranty that will come with the roof.

Outstanding communication. We are delighted to be up and running with our solar!Posted onJosh LentTrustindex verifies that the original source of the review is Google. We've had quite a bit of work on our house in the past year and have had half a dozen contractors working on various projects. By far, Porter Electric was the easiest contractor to deal with and also the contractor that we had the most confidence in. The communication was great from the initial quote to the final approvals. The workmanship is top notch and we have had zero issues with the system. We are so happy with the results that we have reached out to them for another project.Posted onGavin BrennanTrustindex verifies that the original source of the review is Google. We had a great experience with Porter Electrical taking care of our solar installation. Good price, excellent work, and a smooth process. We highly recommend them.Posted onDoris JurissonTrustindex verifies that the original source of the review is Google. Porter Electric was great to work with. I would use them again and have referred them to a friend. They communicated well, answered all our questions and handled all the paperwork and permitting. We have a historic house so worried about how the panels would look and they did a great job. They also had the best price per KWh.Posted onMary LaRockTrustindex verifies that the original source of the review is Google. I love my solar installation!! I have had 3 months this summer with my electric bill being $0. So far everything has been working perfectly! No problems or issues whatsoever. I’m very pleased with my system.Posted onChris HebertTrustindex verifies that the original source of the review is Google. I would highly recommend Porter to anyone, their expertise and attention to detail are top notch! They take the time to do things right and take pride in it and that's hard to find these days.Posted onpeter vTrustindex verifies that the original source of the review is Google. Our solar system install was just completed and the crew did an amazing job. Both with the quality of work and the site clean up. Also, I asked many questions as the install was underway and they were all received and responded to in a timely and useful manner. Could not have asked for a more professional crew. This install was done in Chichester NH and I would highly recommend Porter Electric for any of your solar and electrical needs. Schedules were kept and completion was done on time as promised. The office staff at Porter was also very helpful and guided us thru the process from start to finish.Posted onKyle PepinTrustindex verifies that the original source of the review is Google. Friendly, knowledgeable, professional, would recommend to friends and family!Posted onBill GoldsworthyTrustindex verifies that the original source of the review is Google. Chris Porter and his team at Porter Electric were excellent to work with. They worked with us to optimize a 10.2 kW system with 2 Enphase batteries for backup electricity. Outlaying a substantial initial investment, finding the right installer who is knowledgeable, and trusting the project would not run into unknown issues was a large concern for our family. From initial contact through the design and build process, Porter Electric exceeded our expectations. Communication was constant, thorough, and helped allay the concerns we may have had. Their work was efficient, and their crew was exceptionally clean with their work. They answered all of our questions and helped us understand everything about our system. After installation, we experienced a delay in meter installation through our electric supplier. However, Tara and the team of professionals at Porter Electric remained in contact with our electric supplier to keep our project moving forward. We are not only generating the power we use every day, but we are also returning to the grid the extra 30% we have been producing. We highly recommend Porter Electric for your solar and electrical needs.Posted onRaymond E. Leavitt JrTrustindex verifies that the original source of the review is Google.
