After meeting with 6-7 solar installers, we went with Critical Mass for our solar install. Freddy was very friendly and knowledgeable and not at all pushy. He gave us the two options available during our meeting and sent over the spec sheets to compare. When we were about ready to make a decision, he let us know he got in a few LG panels (our 1st choice) and gave them to us for a great deal. We were quoted these same panels from a large local installer and Critical Mass beat their price by $6k with 5 more panels than the big guys. They were also able to get our install completed within a month and a half of signing the contract! Tyler and his team did a great job installing the panels everything looks great; the panels, the routing, the junction boxes. The team was very active getting all inspections competed quickly and our town required three. I would definitely recommend using Critical Mass for your solar needs!

More than half of the solar salespeople we talked to don't actually know how the system works. The person who does is never there in person. Anytime you ask a question, you get a guess or they say they have to ask the project mgr. This is not the case with Freddy. As the owner of the company and his own solar system, he is knowledgable. There is no project mgr because he is the project mgr. Here are some stats... Our national grid bill is usually around $350 per month which is more than the cost of our solar loan. Our first bill after the install was $72 only have 19 days of solar. Our next month was $-44.07. If you are looking at leasing, you are looking at the wrong option. If you are looking at another company, you are looking at the wrong company. The company is Critical Mass Solar. Freddy, call me if you need help convincing a client.

Freddy and his team were fantastic! We had a 40 panel micro-inverter system installed. We went from quote to live within a few weeks, which was faster than other companies promised. Communication was excellent along the way, with every question answered promptly and thoroughly. The installation team, Tyler and his associate, were extremely professional and did a very clean job. It was very clear they took pride in their work. Freddy took care of all of the paperwork with National Grid and the Massachusetts SMART program. It was effortless from my perspective. I had considered going with one of the bigger solar companies, but I'm so glad I went with Critical Mass. The personal service they provide sets them above the rest.

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 Critical Mass 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 Critical Mass 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 Critical Mass 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.

Assess warranties, support, and the installer's experience while also checking for customer feedback and references. Gauge their responsiveness and customer service, ensuring they educate you about the process. Consider an installer's licensing, and certifications. Request accurate energy production estimates and review contracts for transparency.
