How to Choose the Right Solar Installer

Quick Summary

Going solar is a major investment. The right installer ensures your system performs reliably for decades. The wrong choice can leave you frustrated with poor workmanship, hidden costs, or a company that vanishes when you need service.

In Western Massachusetts, homeowners typically weigh two options: national providers or local companies. Here’s what to consider.

National vs. Local: Why It Matters

• National providers bring scale and brand recognition, but they often operate through call centers, remote sales teams, and subcontracted crews. That can mean a one-size-fits-all approach and less accountability once the system is installed. These companies sometimes even close offices and leave entire states when it suits corporate priorities.
• Local companies can provide accessibility and a personalized touch big providers can’t match. But not every local installer has the same capabilities. Some operate as part-time solar contractors, dabbling in solar and other trades instead of concentrating full-time on solar. Many lack dedicated service departments, advanced design tools, or modern business systems.

What to Look for in a Local Installer

Scale and Capabilities 

For homeowners, scale matters because it gives you access to options and support that one-truck outfits can’t provide.  Valley Solar’s volume means we qualify to offer leasing programs, broader equipment choices, and run a full-time service department — while still staying deeply local. Valley Solar is the largest residential solar installer in Western Massachusetts by volume (Ohm Analytics Data, 2025). 

Service and Accountability

Be wary of “ultra-low cost” operators who cut corners or promise warranties they can’t possibly deliver on. Look for proof of long-term service. Valley Solar puts service first with: 

• SunAlert™ proactive monitoring to track your system 24/7.
• A 95% production guarantee in writing — if your system underperforms, we pay the difference.
• A dedicated service team committed to supporting systems for decades.

Experience With Complex Projects 

It’s one thing to install a simple rooftop system. It’s another to integrate solar with storage, multi-roof layouts, or challenging structural conditions. Valley Solar leads the region in advanced battery projects and has the expertise to handle complexity that others avoid. 

Trusted by Experts 

Local building inspectors — the professionals who see every installer’s work — have chosen Valley Solar for their own homes. That trust from within the trades speaks louder than any marketing claim. 

Reputation

A company’s reputation is built project by project. Valley Solar is consistently recommended for professionalism, workmanship, and reliability, backed by strong reviews and referrals from satisfied customers.

Step-by-Step: How to Evaluate Installers

1. How much experience do they really have?
   Look for annual installation volume and references that prove staying power.
2. Who actually does the work?
   Is it an in-house crew of licensed electricians, or a patchwork of subcontractors?
3. Are they equipped for today’s technology?
   Do they work with batteries and advanced monitoring tools, or are they still offering yesterday’s solutions?
4. How accurate are their estimates?
   Some installers inflate production numbers to win the sale, setting customers up for disappointment. Valley Solar’s estimates are backed by engineering software and a written production guarantee.
5. What happens when you need service?
   Is there a dedicated service department with real accountability, or do they juggle service and new installations with the same small crew.
6. How are the reviews?
   Talk to friends and really read the reviews for detail and authenticity. It is ok to ask for references, too.

Helpful Tips & Watchouts

• Don’t be swayed by the lowest bid — it usually hides cut corners.
• Don’t fall for overblown warranties that don’t make sense.
• Avoid “sign today” sales pressure tactics.
• Confirm exactly who will install your system — not just who sold it.
• Choose providers with a proven service record, not just a sales office.
