About Spartan Solar

At Spartan Solar, we are dedicated to installing the best possible solar hot water systems. We choose our equipment based on performance, robustness, and warrantee support. We pay great attention to detail and appreciate that our installations are only as strong as the weakest link. We also ensure that our client's homes are respected. We call before we show up and leave the site cleaner than we found it.
Our stock panel is manufactured by Sunearth in California. Sunearth is a worker owned co-operative that has been manufacturing solar hot water panels since 1978. Our stock tanks are made by Stiebel Eltron whose U.S. office is right here in Hatfield, Massachusetts. Stiebel Eltron tanks come with a host of features including the highest performing heat exchangers in the industry and a life-time warrantee.
All of our systems come with a 2 year comprehensive warrantee. They also come with a Solarwave data-logger that alerts us if anything were to go wrong, so you won't need to check-up on your own system to make sure it is properly working.

Spartan Giordano has been installing and servicing solar hot water systems throughout western Massachusetts and Southern Vermont since 2010. He studied at Greenfield Community College in their nationally acclaimed Renewable Energy/ Energy Efficiency program. Spartan started his career in this field when he and his wife Hannah decided to design and build their own super-energy efficient home in Greenfield, Massachusetts. Spartan installed both solar PV and solar hot water on his home, which allows their home to produce more energy than it consumes. You can learn more about their home at Spartan's blog. Having your installer understand not just solar hot water, but roofing, walls, and how to make our homes more energy efficient, means that installations go smoothly and are problem-free.
