☀️ Transformation Tuesday! ☀️

This week, we're featuring a home in Chatham, NH that made the switch to clean, renewable energy with a 6.6 kW solar array installed by the 603 Solar team.

What started as an unused section of roof is now a power-producing asset, helping the homeowner generate their own electricity, reduce dependence on utility rates, and invest in long-term energy savings.

Every solar project is unique, and this installation is a great example of how even a modest-sized system can make a meaningful impact. Our team handled everything from design and permitting to installation and system activation, making the process simple from start to finish.
