Local Factors
Navigating the local landscape is crucial for a smooth solar panel installation. In Dunstable, being located in Middlesex County, you’ll need to adhere to specific permitting requirements. This often involves submitting detailed plans to the town’s building department, ensuring compliance with electrical and structural codes. Your installer will typically handle this process, but it’s good to be aware of it. The SMART program is also a crucial factor. The Solar Massachusetts Renewable Target (SMART) program ensures you receive a fixed rate per kWh produced for 10 years, incentivizing solar energy generation. Plus, the high utility rates in Massachusetts, particularly from Eversource and National Grid, make solar a wise investment to avoid future utility hikes. Labor rates for solar installers in the area are competitive, and you should obtain multiple quotes to ensure you’re getting the best price. Remember to verify your contractor’s license at Massachusetts Department of Energy Resources (DOER).
Weather Impact
New England’s climate, with its distinct seasons, has a unique impact on solar panel performance. While some might think cold winters are a detriment, solar panels actually perform excellently in cool, sunny weather. In fact, the cooler temperatures can even improve efficiency. Snow accumulation is a concern, but most solar panels are designed to shed snow quickly, especially if installed at an angle. Furthermore, Massachusetts residents can take advantage of net metering 2.0, “banking” excess energy generated during the sunny summer months to offset electricity usage during snowy winter months. Plus, remember that solar systems are 100% exempt from Massachusetts sales tax and won’t increase your property taxes for 20 years.
