The Benefits of Upgrading Your Panel

Investing in a main panel upgrade may not be the most exciting home improvement, but it’s one of the most important since it brings significant long-term benefits.

  • Increased Electrical Capacity: A modern panel gives you the power to run multiple high-demand appliances without tripping breakers or stressing your system. This is essential if you're expanding your home, upgrading appliances, or integrating solar energy.

  • Improved Home Safety: Old panels can overheat, arc, or catch fire—especially if they’re damaged, improperly installed, or not designed for today’s loads. Upgrading ensures your system meets modern safety standards and significantly reduces the risk of electrical hazards.

  • Support for Solar and Battery Systems: If you're going solar, your panel must be able to handle energy flowing into your home from your solar array, not just out. Many older panels aren’t designed for this kind of system. A modern upgrade ensures full solar compatibility and compliance with utility requirements.

  • Greater Reliability: Say goodbye to nuisance trips, brownouts, or unexplained outages. A properly sized and professionally installed panel keeps your home running smoothly and efficiently, even during high-demand times.

I am very happy with my new roof from TSP. I worked with Sinclair who was easy to work with, professional and took the time to answer all my questions and explain everything to me regarding the process, workmanship and materials. I would recommend TSP to anyone who asked me for a referral and about my experience.

I would like to extend my sincere gratitude to Mario for providing exceptional service throughout my experience. He thoroughly educated me on the benefits of solar energy compared to continuing with PG&E. Mario’s professionalism was evident, yet his calm and friendly demeanor made the process completely hassle-free. Although I initially declined his offer, after a couple of years and as my family grew in size, I realized that solar energy would be the most beneficial choice for my household, especially with the rising costs of utilities. I reached out to Mario once more, and he worked out all the details for me. To my surprise, he provided a quote that beat all the others I had received. His team was equally impressive—friendly, efficient, and prompt. During the installation process, I also had the pleasure of working with Jorge, who was incredibly personable and professional. His crew demonstrated exceptional skill, working swiftly and effectively. They even went above and beyond by cleaning my gutters, showing me before-and-after pictures, and impressing me with their attention to detail. When I inquired about the cost for this additional service, they insisted that it was a simple task and didn’t charge me. Once the panels were installed, a city inspector came by to assess the work, and he praised the quality of the installation, confirming it was ready for operation. Mario took the time to educate me once again about how the panels function, the NEM charges, and how they would be integrated with my wireless network. The system was up and running smoothly. A couple of years later, when I switched internet providers and encountered an issue with my network not connecting to the solar system, I reached out to Mario once more. Without hesitation, he and his team came over, diagnosed the problem, and seamlessly reconnected everything at no additional charge. The service provided by Mario, Jorge, and the entire TSP Roofing and Solar team has been outstanding. I am extremely grateful for their professionalism, dedication, and commitment to customer satisfaction. Thank you, Mario, Jorge, and the whole crew!

When I developed roof leaks this spring, I knew that most of the problem came from an HVAC installation that involved ripping out (I watched, that's what they did) the old 3" vent pipe, and putting in a 4" pipe. It leaked badly, and I had the HVAC guys back two or three times, but it still dripped when it rained. The problem was, years prior to this I also had solar installed, and there was a drip under the solar, which continued. My original solar installer went out of business. I also had a drip on my front porch during some rain storms, but not all. The roof was supposed to last at least three more decades and was nowhere near the solar. So, I had roof problems with no one that I trusted to do the roof repairs. I called the Solar Pros because I knew of Mario's and Javier's work ethic and customer service in the solar industry. I knew they had seen a need to make repairs under manufacturers' warranty claims for other orphaned solar customers, and also would remove and reinstall. When I had technical issues with a bad breaker, I called them for that and found out that they had expanded their services beyond solar equipment to roofing since they so often need to be addressed at the same time. Very quickly, Mario climbed on the roof, took detailed video (so I could see what he saw, and his team would have a visual of the scope of work), and had his team (of 2) come out shortly after. I was delighted to see that they were not like my general contractor, my HVAC guys, or the solar installers (none of them roofers), but they went back to basics and removed all the caulking and mangled shingles in three different locations, down to the rubberized ice shield. The Solar Pros fixed these roofing errors with new shingles, in one day. I can't wait for it to rain! GOOD NEWS UPDATE: No leaks, after wind and downpours!

The owner Mario came to my home and personally walked me through the roof and solar process. Kept me updated with photos of the progress every day. Had a beautiful new roof and gutters installed in under a week. Excellent work and service!

I’m so grateful I run into this company. I was referred to them by a friend. They installed my solar system. I never thought of solar before but after all the research and review, I decided to install the solar system. I’ve saved so much money. My bill now is no more than $15 a month (electricity only). My true up bill last year was -$120. I’m really thankful for their excellent job and service. Mario delivered what he promised. And I haven’t had any issue with my system since 5 years ago. Now that the electricity cost is so high I can’t imagine how much I would be paying to PGE. A truly life changing.

Why Upgrade Your Main Panels?

Just like any other system in your home, solar panels don’t last forever—and technology evolves fast. If your panels are older, underperforming, or simply not enough to meet your energy usage, upgrading can help you get more power, better efficiency, and greater long-term savings. Here’s why many Hercules homeowners are choosing to upgrade their solar systems:

  • Increased Energy Demand: If you’ve added an electric vehicle, built a home office, or installed energy-hungry appliances, your existing panels may no longer produce enough energy.
  • Outdated Technology: Solar panel efficiency has come a long way. Today’s panels produce more energy in less space, making them perfect for limited roof areas or expanding your current system.
  • System Expansion: Adding new panels to an existing array is a smart way to boost your energy independence and reduce reliance on the grid.
  • Battery Integration: Planning to install a backup battery? An upgrade ensures your panels can charge it effectively and consistently.
  • Aging Equipment: If your system is 10–15 years old, it may be time to replace worn-out inverters, wiring, or mounting hardware for continued safety and efficiency.

Our team evaluates your existing system to determine if a partial or full upgrade is right for you, then works to deliver maximum value with minimal disruption to your daily life.
