The Challenge

Arlington Toyota, motivated by a dual mission to reduce carbon emissions and improve margins through lower energy costs, sought a sustainable energy solution. Solar One was introduced to the management team as the ideal partner to navigate this green energy journey.

Financial Ingenuity

Recognizing the financial constraints upfront, Solar One leveraged Arlington Toyota’s tax liability to fund the installation. The dealer capitalized on Illinois’ compelling incentives, including the state’s SREC program, Commonwealth Edison’s net metering initiative, and the federal ITC, accelerating the return on investment to positive by month one.

Cutting-Edge Solar Infrastructure

Solar One implemented a state-of-the-art solar system featuring SolarEdge inverters paired with REC Alpha Pure-R400 – 430 Watt panels, creating an impressive 650-kilowatt solar array atop the Toyota dealer’s roof.

Operational and Financial Impact

The solar system, operational since 2022, is projected to power the dealership for a lifetime of 40 years, resulting in estimated electricity savings of $1.5 million over 25 years. The installation boasts a substantial solar capacity of 641 kW, offsetting 30% of electricity consumption and contributing to a greener, more sustainable operation.

Net Metering Compounding Savings

The net metering program enabled Arlington Toyota to realize compounded year-over-year savings. Excess credits generated during peak solar production in the summer months were seamlessly utilized during the winter, ensuring consistent energy cost reduction.
