Residential Solar Panel Installation
Residential Solar Panel Installation in Lawrence, MA and the Merrimack Valley
Solar power is one of the smartest upgrades for your home, but only when wired right. Amaury Castillo Electric Corp designs and installs systems built to last.
What Our Residential Solar Panel Installation Includes
Solar is an electrical project first and a roofing project second, and that order matters. We handle the full scope of work, from the initial site assessment to the final inspection, so your system ties into your home's electrical panel correctly and meets code from day one. Rising utility rates have made solar one of the smartest upgrades a homeowner can make, and we build every system to perform safely for decades.
Our residential solar panel installation service covers:
- Site evaluation and system design sized to your home's energy usage
- Panel mounting, wiring, and inverter installation
- Electrical panel upgrades when your current service cannot support solar
- Solar panel removal and reinstallation for roof replacement or repair projects
- Solar panel troubleshooting and repair for systems that are underperforming
- Permitting, utility coordination, and final inspection sign-off
Our Process
How Our Solar Installation Process Works
Every solar project starts with a conversation about your home's roof, your electrical panel, and how much of your energy use you want to offset. From there, we handle each stage so you are never left guessing what comes next.
-
Step 1: Site Assessment and System Design
We evaluate your roof's orientation, shading, and structure, along with your current electrical panel, to design a solar array sized to your home's actual power needs.
-
Step 2: Permitting and Electrical Installation Planning
We pull the required permits and map out the electrical installation, including any panel upgrades needed to safely support the new solar equipment.
-
Step 3: Panel Mounting and Wiring
Our crew mounts the panels, runs the wiring, installs the inverter, and connects everything to your home's electrical system with the same care we bring to any residential electrical work.
-
Step 4: Inspection, Activation, and Troubleshooting Support
After a final inspection and utility sign-off, we activate your system and walk you through how it works. If anything needs adjusting down the road, our solar panel troubleshooting and repair service keeps it running the way it should.

-
Licensed Electrical Contractor, Not Just a Solar Installer
We are a full licensed electrical contractor, which means your solar system is wired by someone who understands your entire home's electrical service, not just the panels on the roof.
-
Built for Roof Replacement and Future Repairs
Roofs eventually need replacing, and solar panels need to come off and go back on correctly. We handle solar panel removal and reinstallation so your roofing project and your solar investment stay protected.
-
Honest Troubleshooting When Output Drops
If your system is producing less power than it used to, we diagnose the real cause, whether it is a wiring issue, an inverter problem, or something else, and fix it instead of guessing.
Solar Panel Removal, Reinstallation, and Repair for Existing Systems
Homeowners who already have solar panels often need help when a roof replacement, storm damage, or a drop in energy production comes up. We work with existing systems just as readily as we design new ones.
Common situations we handle include:
- Solar panel removal before a roof replacement or repair
- Solar panel reinstallation once roofing work is finished
- Solar panel troubleshooting when output drops or monitoring shows an error
- Solar panel repair for damaged wiring, connectors, or mounting hardware
- Electrical panel upgrades to support an expanded solar array
- Inverter replacement or reconnection after electrical service upgrades
Common Questions
Solar Panel Installation FAQs
Here are answers to the questions we hear most often from homeowners considering residential solar panel installation in the Merrimack Valley.
Do I need an electrical panel upgrade before installing solar panels?
It depends on your home's current service size and how much power your new solar system will generate. During the site assessment, we check your panel's capacity and let you know upfront if an upgrade is needed to safely handle the new load.
What happens to my solar panels during a roof replacement?
We handle solar panel removal before your roofer starts, store the panels and hardware safely, and complete the solar panel reinstallation once the new roof is in place. This protects both your roof warranty and your solar equipment.
My solar panels are producing less power than before. Can you fix that?
Yes. A drop in output usually points to a wiring issue, a failing inverter, or a connection problem, and our solar panel troubleshooting process finds the specific cause so we can make the right repair instead of a guess.
How long does a typical residential solar panel installation take?
Most home solar installations take one to two days for the physical electrical installation, though permitting and utility approval can add a few weeks before activation. We walk you through the full timeline before work begins.

Mr. Castillo was prompt for the scheduled appointment, he came equipped with his tools/van/uniform. He went to work immediately, friendly, knew where to trouble shoot the electrical problem, corrected the problem within one hour of arrival while running down to the basement and up to the second floor bedroom several times where my daughters lights had gone out. I recommend this electrical expert to repair your electrical issues and he can also communicate in spanish , I give this company five stars *****!

I recently had several electrical issues at my home and was fortunate to find Amubury. He arrived promptly and was able to accurately diagnose the problems within minutes. I was incredibly impressed that he was able to fix everything in just a couple of hours. He even took the initiative to run out and purchase a necessary replacement part himself, which kept the process moving efficiently without any delays. Throughout the entire experience, Amubury was professional, courteous, and highly efficient. What stood out most was how thorough he was—he took the time to clearly explain the issues and walked me through the solutions, making sure all of my questions were answered. His pricing was very reasonable given the high quality and speed of his work. I was genuinely impressed and would highly recommend his services to anyone in the area. I will certainly be calling him again for any future electrical needs!

I was lucky enough to meet Amaury when I moved into my “new” home almost 10 years ago and he has been my go- to for everything electrical since! From installing a new fan on a cathedral ceiling to recessed and living room spotlights to changing out fan switches in bathrooms - he has done it all. Fast, responsive, fair and courteous- I really can’t say enough about Amaury, he truly is the BEST. Thanks Amaury!

We lucked out when I found Amaury on Angie's List years ago. Since then, he's fixed issues that have cropped up, installed a generator hook-up, and then replaced our entire (very old) electrical panel. He's responsive, thorough, knowledgable, insightful, voluntarily explains things and is fairly priced. Cannot recommend him enough!

Couldn’t be happier with our electric panel upgrade! From start to finish, the process was smooth and stress-free. Amaury was knowledgeable, respectful of our home, and did excellent work. Everything works perfectly and the upgrade gives us real peace of mind. I’d absolutely use them again.

Amaury quickly came over to check over the electrical wiring for our generator and electrical box, making a couple of thoughtful suggestions and quickly ensuring that we had heat in the event of a power outage in the Jan '26 snowstorm. Would recommend Amaury for any number of electrical work.

Amaury was super knowledgeable, efficient (he didn’t waste time), and I appreciate that he was conscious of the neat and clean look of the job putting in some complicated ceiling lighting. He asked me my opinion along the way so as to get just what I wanted while completing the job. And he left no mess behind. Thank you Amaury- first time using your service. Looking forward to having you as a reliable electrician for future jobs.
