I had read reviews for 603 Solar and that is one of the reasons I went with them. I am extremely pleased with my experience dealing with Zach, Tyler and everyone from 603 Solar. They are very responsive, knowledgeable and professional. I highly recommend them.

We used 603 for our PV system. Zach and his crew were great to work with. Though, some supply issues which everyone is facing did push the project back it was worth it. He installers and design team were just great at answering all of our questions no matter what. We spoke to two other companies locally who also have great reps but 603 came in right on our budget and were honestly upfront the entire time about any delays.

I learned a lot from Scot, and it was a lot of fun He gave me the details and let me make up my mind. I did and ordered a 10 panel system. Well as more information came in, I saw that I really wanted to do more than I originally thought so I changed the order in coordination with Scot's input to a 28 panel system. We had some issues with changing city regulation and Erin made the changes that worked as well as submitting all that paperwork with Eversource and the State for the rebate. I continue to talk to Scot, getting suggestions for my house in Florida which will be getting panels in August. The solar panel system has been running since late November and I am happy, happy and really glad I was able to upgrade to a 28 panel system. 603-Solar and it's people were and continue to be fun to work with and I highly recommend them to meet all your solar panel system needs.

We're very pleased with our roof-mount solar array from 603 Solar. Their team was easy to communicate with throughout all stages of the project. When upgraded panels came onto the market, they updated the original layout design to best fit our roof and maximize wattage. 603 followed up after the install, ensuring that everything was in good working order and that we had access to the system monitoring app. Sean, Erin, and Zach were courteous and professional throughout. Highly recommend.

We are delighted with our experience with 603 Solar throughout the process. In December 2021, 603 Solar completed the installation of our 10kWa Solar array, made up of 25 400W panels. If you are considering solar for your home, we highly recommend the team at 603 Solar.

Moon | Randolph, NH

We looked into multiple companies for our Solar install and decided on 603 Solar as they were very attentive to our inquiries, honest with their answers and seemed very easy to work with. Everyone who was involved with our project from 603 Solar was great to work with. Great communication throughout the entire process. We would highly recommend choosing 603 Solar for your own project.

Great company to work with! Highly professional and reliable. We installed our solar panels recently. Sean and his team did a detailed estimation of our power consumption and came up with a plan that would work best for us through the year without paying for electricity. Installation was efficient and completed as promised. I highly recommend 603 Solar if you are considering one for your home.

Dana | Rumney, New Hampshire

Had 603 install 36 panel ground mount solar system summer 2021. The price was very competitive and the representative friendly and knowledgeable. The installer is subcontracted but works almost solely for 603. The work was done efficiently without any mess. I would definitely recommend that you talk with them if you are considering solar.

What To Look For In A Solar Installer?

When looking for a solar installer, it's essential to consider various factors to ensure you choose a reputable and competent company that meets your needs.

When selecting an installer like 603 Solar consider:

Experience and Reputation:

Look for a company with a solid track record and years of experience in the solar industry. Read the latest 603 Solar solar reviews from past customers to gauge their reputation.

Certifications and Licenses:

Ensure the installer holds the necessary licenses and certifications required in your area. Look for certifications from organizations like the North American Board of Certified Energy Practitioners (NABCEP) to verify their expertise.

Quality Products and Technology:

Inquire about the types and brands of solar panels, inverters, and other equipment they use. Quality matters for long-term performance. Ask if they offer the latest solar technologies, such as high-efficiency panels or energy storage solutions.

Warranty Information:

Understand the warranties they offer for equipment and workmanship. A reputable installer should provide comprehensive warranties. The majority of modern solar panels are equipped with a warranty spanning 20 to 30 years, encompassing both the product's integrity and its energy output. An ordinary workmanship warranty offered by a certified company typically provides coverage for solar panels for an average period of 10 years.

Transparent Pricing and Contracts:

Get detailed solar quotes that include all costs, from equipment and labor to permits and inspections. Review the contract carefully to ensure it's clear and transparent, with no hidden fees or surprises.

Local Knowledge:

Choose a company familiar with local building codes, regulations, and permitting processes. This can expedite the installation and ensure compliance.

Customized Design:

Look for companies who provide custom solar system designs tailored to your specific energy needs and property characteristics.

Energy Production Estimates:

The installer should provide accurate estimates of how much energy the system will generate, factoring in local climate conditions and other key influences. If your estimated solar savings are much higher with one solar company, you'll want to inquire further to ensure their savings projections aren't skewed to close the sale. Connect with us for a free estimate.

Financing Options:

Inquire about solar financing options, including purchase, lease, or power purchase agreements (PPAs). Ensure you know the pros and cons of each option.

Customer Service:

Assess their responsiveness and willingness to answer your questions and concerns and consider the installer's commitment to your project satisfaction. Throughout your solar process we’ll advocate for you, ensuring your solar project is done right.

References and Recommendations:

Seek recommendations from friends, family, or colleagues who have installed solar panels. Ask the installer for references from past clients who can share their experiences. You can also read the latest reviews on 603 Solar.

Multiple Quotes:

Don't hesitate to obtain quotes from multiple installers to compare pricing, services, and warranties. Hint: We can help!

Financing and Incentive Knowledge:

Ensure the installer is knowledgeable about available incentives, tax credits, rebates and financing options. At EnergyPal, we’ll help maximize your savings.

Safety Practices:

Confirm that the installer adheres to safety protocols during installation to protect both workers and your property.

By researching and considering these factors, you can select a reputable solar installer who will provide a quality solar energy system and a positive experience throughout the installation process. Connect with us to learn more about the best solar installers in your area.
