Apple Corporate Offices


With the goal to power every corporate facility entirely with energy from renewable sources like solar, wind, hydroelectric, and geothermal, Apple has dramatically reduced the environmental impact of its corporate facilities and data centers. To continue this momentum towards 100% renewable energy, Apple is investing in their own onsite energy production, establishing relationships with suppliers to procure renewable energy off the grid, and reducing their energy needs even as their employee base grows.


Borrego Solar worked with Apple to install rooftop installations on several of their corporate office buildings in Cupertino, California. One solar array is a 554.4 kW roof-mounted system, comprised of 2,310 Sharp 240 watt solar modules. The other is a 201.6 kW roof-mounted system comprised of 840 Sharp 240 watt solar modules. For both sites, Borrego Solar’s installation crews worked after hours so as not to disturb the productivity of the Apple staff. The solar energy systems were affixed to the building rooftops with Sunlink’s Core RMS racking solution at a 5° tilt, facing south.


Apple’s net-metered solar power installations were purchased outright and not financed through a third party solar financing solution like a lease or power purchase agreement. By paying cash, Apple realized the greatest ROI from solar and, per net metering regulation, will receive a full credit at retail rates from PG&E for each kilowatt-hour (kWh) generated and put on the grid. Additionally, both installations qualify for the 30% Federal Investment Tax Credit (ITC) and state subsidies through the California Solar Initiative’s (CSI) performance based incentive (PBI): a cash incentive paid at a predetermined rate per kWh to commercial entities over the first five years their solar energy systems are in operation.
