SunKey Energy strives to provide its customers with the best technology for all their solar needs. Check out our list of preferred products and vendors below:

Solar panels may be on top, but it's the inverter that does all the real work. Choosing an inverter technology is the most critical decision you'll make when going solar. Enphase Microinverters offer the most advanced inverter technology on the market, which means higher production, greater reliability, and unmatched intelligence.

Enphase Micro-Inverters

More reliable

Because they function independently, microinverters are inherently more reliable:
there's no single point of failure in a microinverter system. Plus, we're obsessive about quality, and our products reflect that.

  • If one panel goes down, the others won't go down with it.
  • Enphase microinverters undergo the most rigorous product testing in the industry.
  • We stand by our products with the industry's highest warranties.


Microinverters are safer than other inverter technologies.

  • An all-AC system means no high-voltage DC power on your roof.
  • Enphase Microinverters are commonly chosen for schools, since they meet even the strictest government safety requirements.

More cost-effective

In addition to the greater energy savings from higher production, Enphase microinverters are just a better long-term investment.

  • Enphase microinverters come with a 25-year warranty; string inverters need to be replaced at least once in the lifetime of the system.
  • Streamlined components make for quicker and less costly installations.
  • High-quality materials and remote problem-solving save money on repairs.

The sonnen Virtual Power Plant (VPP) software used in the sonnenCommunity enables our partners to address customer needs, from individual homes to the larger demands of the grid infrastructure, by using distributed energy storage capacity to provide grid services.

Virtual Power Plant (VPP)Capabilities for Dynamic Control

Grid Enhancing Services

Beyond individual customer benefits, sonnen’s energy storage solutions and Virtual Power Plant software provide utility services, including:

Power Outages and Peak Demand Services
sonnen enables utilities to aggregate storage assets for use as frequency support to minimize power losses for customers during extreme weather and peak demand events.

Solar Self-consumption & TOU Management
sonnen’s built-in energy management algorithms reduce local and temporary peaks and enables customers to optimize consumption during TOU rates.

Capacity Bidding Capabilities
sonnen is capable of aggregating 100+ kW of curtailment within a single defined region allowing for earning capacity and wholesale payments into day-ahead, real-time and regulation markets.

Localized Peak Load Management
With sonnen’s innovative sonnenCommunities, utilities can utilize alternatives to traditional costly upgrades, to manage peak load for homes, neighborhoods and cities to solve grid upgrade issues.

Modernizing the Grid and Bolstering Utility/Co-op Infrastructure
sonnen is implementing future-proofing projects with TEP and EPRI (utility led project), Dairyland Coop (behind-the-meter) and APS (behind-the-meter & VPP) to use storage to provide DER resources into hives of dispatchable capacity.
