(In thousands, except per share data and percentages)

Total revenue increased 5% compared to the first quarter of 2021. Demand for our microinverter systems remained well ahead of supply in the second quarter of 2021, as component availability continued to be constrained. Our operations team did an excellent job of navigating these component supply constraints to best service our customer demand, while our sales team focused on managing the channel and working closely with our installers and distributors.

Our non-GAAP gross margin was 40.8% in the second quarter of 2021, compared to 41.1% in the first quarter of 2021, as higher logistics and expedite costs were partially offset by disciplined pricing and favorable product mix. Non-GAAP operating expenses increased to $51.7 million in the second quarter of 2021, compared to $43.7 million in the prior quarter, primarily due to additional investment in R&D and marketing programs, the first full quarter of consolidation of our two recent acquisitions, and increased hiring. Non-GAAP operating income was $77.2 million in the second quarter of 2021, compared to $80.2 million in the first quarter of 2021.

We exited the second quarter of 2021 with $1.3 billion in cash and generated $65.6 million in cash flow from operations. We repurchased approximately 1.7 million shares of common stock for a total amount of $200.0 million on the open market in May 2021. Capital expenditures were $16.4 million in the second quarter of 2021, compared to $9.9 million in the first quarter of 2021. The sequential increase was due to the expansion of manufacturing capacity at our Mexico and India facilities, along with investment in IT and cloud infrastructure.

Strong demand for our microinverter systems across all regions continued in the second quarter of 2021. We introduced our Load Control feature for our Enphase Storage systems in late May, which provides homeowners the ability to conserve their energy consumption by shedding non-essential loads during an outage and thereby extending the backup duration. We optimized our storage pricing for installers and continued to improve the installer experience by simplifying the commissioning process and reducing installation times. As a result, since June we have seen accelerating demand for our Enphase Storage systems.

We are making good progress on digital transformation. Both of our recent acquisitions are fully integrated and exceeded our expectations with record revenue and installer counts in Q2. The Montreal team, which provides design and proposal software, added a significant number of new installers, while the Noida team, which provides proposal and permitting services, also experienced a significant increase in new requests. Both teams plan to release new products that will improve the customer experience and enable our installer base to leverage them as soon as possible.

Our Enphase Storage customers in Connecticut, Massachusetts and Rhode Island can now participate and earn money through the ConnectedSolutions program, a utility-run incentive program to reduce electrical demand during high-use periods. Customers can sign-up, monitor, and control participation in the program using our Enlighten™ mobile app. We are excited to participate in a grid services program for the first time and expect to do more in the future.


On April 19, 2021, Enphase Energy announced that Transdev, a multinational transit operator, selected Enphase microinverters for the first public transport depot in Australia to feature a fully solar-powered bus. Transdev plans to electrify the public transport network in Australia to show that it is more economical both financially and environmentally to transition to solar-powered electrical vehicle (EV) buses. 

On May 25, 2021, Enphase Energy announced Load Control, a new feature for its Enphase Storage system. Load Control enables a homeowner to designate four loads and prioritize them for what gets power in the event of a grid outage. All of this is done through the Enlighten mobile app, providing homeowners more control over their energy consumption while driving an improved installer experience.

On June 29, 2021, Enphase Energy announced the launch of its Encharge™ storage system in Germany, the product’s first expansion into a market outside of the U.S. The Encharge storage system offers configurations ranging from 3.5kWh to 42kWh, along with the option to upgrade and expand through the lifetime of the system. Homeowners can also use the Enphase Enlighten mobile app to intelligently manage their solar energy in self-consumption mode to minimize the use of electricity from the grid, which saves on energy bills.


For the third quarter of 2021, Enphase Energy estimates both GAAP and non-GAAP financial results as follows:

  • Revenue to be within a range of $335.0 million to $355.0 million, which includes shipments of 60 to 70 megawatt hours of Enphase Storage systems
  • GAAP gross margin to be within a range of 37.0% to 40.0%; non-GAAP gross margin to be within a range of 38.0% to 41.0%, excluding stock-based compensation expenses
  • GAAP operating expenses to be within a range of $105.0 million to $108.0 million, including $48.0 million estimated for stock-based compensation expenses and acquisition related costs and amortization
  • Non-GAAP operating expenses to be within a range of $57.0 million to $60.0 million, excluding $48.0 million estimated for stock-based compensation expenses and acquisition related costs and amortization. The non-GAAP estimates include increased investments in new products, software, and marketing, and a $3.4 million accrual for post combination expenses from prior acquisition
