McKinney Office Building Solar: Local Market Context
Why McKinney
McKinney's booming tech sector and sprawling corporate campuses along the US-75 corridor create concentrated daytime electricity demand that peaks between 2-4 PM—precisely when Texas solar hits maximum output at 5.0 peak sun hours daily. With NREL production factors of 1510 kWh/kW/year, office buildings here see 8-12% higher solar yield than comparable properties in Houston due to McKinney's drier climate and fewer coastal cloud interruptions.
Industrial Corridors
Office buildings cluster heavily in three McKinney submarkets: the Craig Ranch development west of the Dallas North Tollway, the Eldorado Parkway tech corridor near Toyota's headquarters campus, and the older Central Expressway office parks between Virginia Parkway and Eldorado. Craig Ranch alone has added over 2 million square feet of Class A office space since 2015, nearly all with favorable roof orientations and minimal shading.
Oncor Specifics
Oncor requires commercial solar customers in McKinney to file an Interconnection Request under their distributed generation tariff, which currently processes systems under 1 MW within 25 business days for standard office rooftop installations. The $8.50/kW demand charge applies to the highest 15-minute interval each month, but because McKinney operates in a deregulated market, office owners can pair solar with retail electricity providers offering solar-friendly rate structures that credit exports at real-time nodal prices through the North Texas load zone.
