Rooftop Solar Puts Local Business on Path to Net Zero

The rising costs of oil and gas has peaked Mainers’ interest in heating alternatives, and a new generation of heat pump technology and falling costs of solar electric modules have combined for a vision that many would not have believed feasible: affordable electric heat offset entirely by solar power.

Leading this charge is Northeast Radiant Technology (NRT), who recently hired ReVision Energy to install a 14.4kw solar electric array on the open south-facing roof of their Gardiner, Maine offices, alongside a Daikin Altherma air source heat pump.

Being full-service heating system design professionals, NRT knew intimately the full range of heating options available. Their choice to go with solar and an air-source heat pump was based on a commitment to environmental responsibility and an exciting vision: a heating system powered solely by the sun.

"The ability to go net-zero with a photovoltaic array for a small business like ours was really attractive,” says NRT Co-founder Rob Brown. “With our competitive grant, our time to pay back the system cost is less than 7 years and even with just the base tax credit it’s about 13. We felt if we could really tread that lightly on the earth for that kind of a price it was well worth it to us. And of course in the end it’s an economic winner as well.”

NRT was able to take advantage of a suite of rebates including a $2,000 Maine state rebate (recently increased to $4,000 for businesses), a 30% Federal Investment Tax Credit, Accelerated Depreciation Benefits, and an Efficiency Maine grant.

Unlike a choice to invest in fossil fuels, NRT knows that in the future their cost of energy will never increase. The solar electric system will produce a little over 18,000 kWh of power a year – a savings of close to $3,000 annually at today’s prices.

The solar electric panels are long-lived, with an expected life span of 30+ years, and contain no moving parts. Whenever the sun is out, clean electricity is generated and either used immediately in NRT’s offices, or exported to the grid.
