It was very nice working with Bill LaCommare on our solar project. Bill's presentation was professional and very informative. He was able to answer all our questions, what to expect with solar power and was hands on during installation making sure things were done correctly. I would highly recommend Bill LaCommare to anyone considering switching to solar power.

Enjoyed working with Bill in the past. He's very patient and answered all my questions. Bill seems to really care for his customers and is looking to get you the best deal possible to meet your needs.

Often mention is made of the weakest link in the chain, Bill LaCommare (aka Vito) was by far, the the full strength of the chain. From initial presentation, through installation to final approval Bill was the go-to person with any concerns or questions answered immediately via email.
Bill's alleged backup people (scripted robots) couldn't hold a candle to his dedication, customer loyalty, solar knowledge & communicative skills.
We are, incidentally, extremely happy with the end result. Did not expect only 14 panels to provide sufficient energy to the HVAC & IT DOES! Last month's (6/24) elec.bill=$11.93/2800 sq. ft home. Money well spent!

I worked with Bill creating and installing a solar system for my residence. He is an exceptional personality, friendly, professional, and always there when I need him. He went above and beyond to make sure that I was satisifed with my solar system and smoothed out every bump in the road.
I wish all sales representatives were as good as Bill is. I would do business with him again with no reservations.

5.6 kW solar and Tesla battery installation for George & Mickey!

We needed to replace our roof and thought it would be beneficial to have solar panels installed, too. Bill LaCommare was not only our sales rep but also had our backs throughout the whole process. There were many moments we had questions about doing the roof and solar panels in the beginning, and we, unbeknownst to us, asked Bill while he was having family/friends time. He kindly told us he would answer our question afterwards, and he followed up. I was quite impressed with his response and patience. As neighbors and friends have noticed and inquired about who installed the solar panels, I have continuously sung praises for both Bill and the Semper Solaris team who managed our roof, solar panel, and now battery installation. The care, the calls to check in with us is why we highly recommend them. Thank you Bill and the Semper Solaris family

Bill LaCommare was our sales rep and he did a great job answering all of our questions and providing us with a fair price. The installation was smooth and complete on time. Customer Support has been very responsive, especially when it comes to obtaining the rebates! They have been great! We got solar and batteries.

Bill is just the ultimate professional. He was very knowledgeable, willing to share his understanding of the products, available solutions and answered all the questions we had. Bill made himself available and even took a call while on vacation in SoCal to resolve open questions
It was refreshing to see how Bill took the time to understand our objectives and goals, build a connection and help define a solution that was perfect for us. We learned about the CA SGIP, PgE medical baseline, inverter options and even how to better care for our existing solar installed assets - all things we had little knowledge of.
Bill set correct expectations for install and the product has now served us for 2 years and we are still very happy.
Thank you Bill LaCommare. You made going with Semper Solaris a great decision.

We had been thinking about going solar for the last several years and finally decided it was time to jump before all the great incentives went away. After getting a referral from my brother-in-law who used Semper Solaris to install their solar, we decided to have them come out and give us a quote. Bill LaCommare was very professional, and we had a great experience. After working up a plan and receiving a quote we decided to go with them. So far, we've been happy with the service and quality of the product.

Bill provided great service for our solar and battery install. He was knowledgeable, easy to work with and responsive. He goes above and beyond for his clients to make sure they are happy. It was a pleasure working with Bill to get our solar system up and running. Highly recommend.

From the initial meeting with Bill we felt extremely comfortable with choosing Semper Solaris as our solar provider. Bill was clear, concise, and explained our options and choices very thoroughly. All follow-ups we had directly with Bill were timely and well explained. As a sales rep we could not have asked for a better representative of the company. Bill was the lone shining star in the entire project
