4 Benefits to Commercial Solar Installation
Save Money and Offset Electricity Bill
1. Commercial Solar Benefits - Save $
Most solar installation projects we do completely offset their home electricity bill. Part of our initial process is to create an energy design of your home by using size of your roof, which direction your home faces, how much sun vs. shade you get, and other parameters. We will then use that design and walk you through whether or not you can completely offset your electricity bill or not.

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.

Thanks guys, you earned the 5 Stars. richard boisvert2024-11-26Trustindex verifies that the original source of the review is Google. Porter Electrical worked closely with us to devise a solar system with batteries that was out of the usual configuration. The result was a system that performed perfectly during power outages. Electrical service shifted seamlessly and even our WiFi suffered no interruption. The work was done on schedule and all debris and packaging disappeared. We are extremely pleased with our experience.

Highly recommend David Janeczek2024-07-03Trustindex verifies that the original source of the review is Google. The Porter Electrical team installed a solar PV array at my property in May of 2024. The team worked quickly while being extremely professional and courteous; more importantly they were able to complete the install in one day. They effectively answered all of my questions prior to and during the install. They connected me to the 'my Solar Edge' app which makes it easy to monitor system performance at any time down to the specific panel from my phone - it couldn't be easier. Finally, the Porter Electrical team is highly responsive and customer focused; great people to work with.

Chris was great to work with and the pricing was very competitive! Jim Doyle2024-06-10Trustindex verifies that the original source of the review is Google. I’m really happy I got Porter in to do our solar with battery storage project. In rural Maine plenty of power outages and we did not want a propane generator for backup. We found Chris thru Energy Sage which got us I think six companies quoting the job. I also contacted two other companies. I did a lot of research found out what type and functions we wanted and went with Enphase solar FranklinWH storage and a Span smart panel. We got it down to two companies and found Porter provided what we wanted at the best price. Porter came in when they said they would and installed what they quoted. Two licensed electrician with two apprentices for two days. It came out great. Clean installation printed labels symmetrical looking layouts. With some of the issues presented to Chris one of his answers was well this is how its going to get done because its the right way to do it. I noticed he changed out some of my breakers the house was wired with some circuits sharing the neutral bringing it up to code which it should have been when house was built. It’s still very new with a bug or two. He’s responsive to these also. Go with Porter! Thanks Chris / Derrick and Kyle!Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
