These folks installed a 27-panel system on my house in October 2025. They listened carefully to my needs in the design process and were open to iterating a bit to get the system just right. Installation was smooth and quick and they handled all the paperwork with PECO, etc. flawlessly. Excellent experience!

I was looking for a local company that had a history of good service, but also had expertise in solar. O’Donnell Solar has both. They have been great to work with, have answered all my questions, and contacted and supported me after the installation to ensure everything was going well.

Everyone at O'Donnell Solar was dedicated and hardworking. Given the circumstances of the residential energy tax credit being prematurely expired by Congress, they had a surge of installations to finish by the end of 2025. They got my install done before the deadline, and they were responsive and diligent at addressing all of my concerns and issues. I'd recommend them to anyone looking for a solar installer.

O'Donnell did a great job on my project . Installed an enphase system and everything went smooth from day 1 . The process was easy and faster than I thought it would be . This should help me eliminate all gas from my house since I can swap to a heat pump .

The O'Donnell team was great to work with, communicated great along the entire process, and the work looks and works great! Highly Recommend!!!

O’Donnell Solar did a fantastic job designing and installing our solar panel system, as well as shepherding our system through the PECO interconnection process. Every individual on their team is professional, knowledgeable and passionate about their work. Special shout out to Brett, our project manager, for being incredibly patient with all of our questions. O'Donnell Solar is a pleasure to work with and we are extremely happy with our new system.

Great experience with Kevin and Brett from their solar team

O’Donnell did an amazing job from start to finish. They worked closely with our homeowners association to make sure we met all the standards. They installed the panels on time and on budget, and made sure the connections with our electric company went smoothly. We couldn’t be happier.
