Totally happy with solar

We added 32 solar panels to our home about four years ago installed by Power Factor. Everything has gone smoothly, saving us tons of $$ on monthly bills, with the added bonus of subsidies and SREC refunds. Most of all, we feel we are helping our world.

Great Customer Service

We appreciate the informative no pressure style! We had such positive experiences that when moved we reached out to Larry to add Solar products to our new home. The assessment showed opportunities to get the best results! We have been very satisfied and would highly recommend

Happy Power Factor Solar customer

Hey now, Since having Power Factor evaluate and propose installing solar panels on our roof, we've had one electric bill over a year an half for $7. When factoring in the SREC credits of around $60/month, and tax savings, our break even on cost will be around 5.5 years. The folks at Solar Factor are professional and honest; couldn't be happier!!!

Power Factor Delivers Top-Notch Products and Service - A 5-Star Experience!

I recently had the pleasure of working with Power Factor, and I must say, their products and service are nothing short of exceptional! Your home is your most valued asset. Power Factor truly understands that and demonstrates a deep respect and understanding of their customers' needs. From the outset, the anxiety that often accompanies major home upgrades was quickly alleviated by the professional poise and demeanor of the Power Factor team. Their staff, comprised of certified electricians, treated my home and property with the utmost care and respect, as if it were their own. One of the standout features of Power Factor is their commitment to punctuality and availability. Post-installation, their team remained accessible, addressing any queries or concerns promptly. This level of post-installation support is a testament to their dedication to customer satisfaction. As a product provider, Power Factor only installs the best technology available. I was particularly impressed with the use of the mobile application "Enlighten" by Enphase. This innovative tool allows me to monitor real-time power production from my home, no matter where I am in the world. The transparency provided by Enlighten adds an extra layer of confidence, allowing me to stay connected to my energy usage effortlessly. Cost savings have been nothing short of incredible since the installation. I find myself proudly boasting about the savings to friends and family, many of whom have also become satisfied Power Factor customers. The investment in solar panels is not just paying for itself; it's adding tangible value to my property. In conclusion, if you're in the market for a reliable and professional solar provider, look no further than Power Factor. Their commitment to excellence, coupled with top-of-the-line products and unmatched service, makes them a standout choice in the industry. I wholeheartedly recommend Power Factor to anyone considering a solar solution for their home. A solid 5-star experience!
