Adding Solar Panels to an Existing System

Reasons for Expanding Your Solar System


Quite simply, more panels = more energy, which equals more savings on your monthly bill!


New home appliances/features could cause an increase in need for more energy generation.


The extra energy needed for EV Charging is a great reason to consider expanding.


With your original decision to install a solar system, you’ve already taken the steps to reduce your electricity bill and convert to clean, renewable energy – but eventually, you may require a PV system expansion, or adding solar panels to an existing system. Sometimes solar customers may find that their circumstances change regarding the amount of energy it takes to power their home, such as an increased use of electricity due to the installation of an EV charging station. 

Because you already have solar panels installed, you probably understand the basics of what goes into a PV system expansion. However, adding panels to an existing solar system comes with its own set of challenges, so there are a few things to consider beforehand.


If you’re an existing solar system owner who’s thinking about adding to your PV system, here a few things you should consider before installing:

Your Increased Energy Needs

There are many reasons why your home may begin consuming more energy, and the solar array that met your needs yesterday is now undersized for today. You might start requiring more energy from your solar panels: installing new appliances, an EV charging station, an addition on your home, a pool in your backyard, or even just the fact that your family is home more than ever. 

Your Roof Space

Often, roof mounted arrays can be constrained by available roof space, but the good news is that there are options. If there isn’t room left on your roof, there are several alternative routes you can take to achieve your goal! You may consider installing ground-mounted solar or adding panels to another surface such as a shed or carport. Luckily, the solar tax credit covers ground-mounted structures as well as arrays installed on a roof.

Your Inverter’s Capacity

The initial installer company sized the inverter to be compatible with the energy output of those panels. Depending on how many panels you wish to add to your system, your inverter may not be able to handle the additional energy output. This would require a new inverter to be installed to properly convert the sun’s energy into usable electricity!


At Sun Service Specialists, we begin the process of adding solar panels to an existing system with a conversation. From there, we’ll look toward a site survey and an assessment of your current system. This allows us to understand how much energy your panels are currently producing, how much energy you’re currently using, and by how much you wish to increase your energy production. We will provide you with a quote for the additional panels and installation before plotting the timeline necessary to complete the installation process. 

With over 50 years of combined experience, the team at Sun Service Specialists are more than capable of adding solar panels to your system and would be happy to help solar customers in need of our services. If you’re interested in a PV system expansion, please contact us today by scheduling an appointment!

Service Manager Joel Robinson was superb. He helped troubleshoot a system his company didn’t actually install, even talking with the manufacturer over the phone on a three-way call with me for well over an hour. When he sent out teams to help, they were led by a young guy named Austin who was not only extremely personable, but knowledgeable and exceptionally helpful. I am so glad I found these guys and cannot recommend them enough. You won’t be disappointed — I wasn’t.

I really appreciate this team for helping troubleshoot and repair an optimizer that had burned out on one of my panels. They were on time, knowledgeable, patient and professional with communication and proper expectations. I thought it was going to be a pricey fix and was worried about that, but to my surprise it was next to nothing because the product was under warranty. They handled all the communication with the manufacturer to get the replacement part. I highly recommend them to anyone who needs service on your solar system, they can do a wide variety of things related to it.

Lauren and the guys were amazingly professional and true experts in providing superb electrical work. They came, planned the work, sent me a reasonable and detailed estimate, and arrived on time and did a phenomenal job of wiring my garage for the Tesla Wall Connector. This was not a job I would have done by just anyone! Thanks for a great job!
