Key criteria for selecting a solar installer
Start by confirming that the company holds a valid Maryland state license, is certified by the North American Board of Certified Energy Practitioners (NABCEP), and carries adequate insurance. These credentials protect you from sub‑standard work and ensure the installer follows local building codes and utility requirements.

Understanding cost components
Quotes typically break down into equipment (panels, inverter, mounting hardware), labor, permitting fees, and optional services such as monitoring or battery storage. Labor rates in Cambridge hover between $1.20 and $1.80 per watt installed, while equipment costs vary with panel efficiency and brand reputation. Request a detailed line‑item estimate to compare offers objectively.
Local incentives and financing options
Maryland offers a 30% state tax credit up to $5,000 and a utility‑specific rebate from Baltimore Gas and Electric (BGE). Installers familiar with the application process can handle paperwork, accelerating credit receipt. Many firms also provide Power Purchase Agreements (PPAs) or solar loans, allowing homeowners to spread costs over 10‑20 years while preserving ownership of the system.
Installation timeline and performance guarantees
Typical projects in Cambridge move from site survey to final inspection in 4‑8 weeks, depending on permitting speed and weather. Look for warranties that cover panel performance (often 25‑year linear output guarantees) and workmanship (10‑year). A clear maintenance plan reduces long‑term risk.
