Now 60+ members strong, SunSpec has com a long way.
In the past four years, we have approved and published 10 specifications, and have several new ones in the works. SunSpec’s latest contributions to the industry include specifications for cybersecurity, inverter control, and plant data reporting. All specifications are available for free download and implementation from SunSpec.org, I am happy to report that SunSpec standards have been adopted both commercially and in the international standards community. We are united in our effort to establish a common language for the industry.

Early Commercialization Finance Gap
Transitional Assistance Needed
19
Solar Access To Public Capital Initiative
Goals Cover early commercialization gap Investigate way to expand capital base Lower costs of RE financing Results Identified public market mechanisms Securitization Master Limited Partnerships Delivered standard documents & processes Engaged 250 investors & developers Initiated “mock” securitization Download:

Concerns About Grid Imbalances Are Growing
21
California Rule 21 Changes Coming
Rule 21 defines how solar plants connect to the grid New revision permits smart inverters To “support” the grid Enable new services & revenue streams Set stage for U.S. rollout
22
Smart Inverters & Storage Coming Together
Demand Response Storage Generation Wider Operating Range (lower Pmin) Voltage Support Regulation Fast Ramping Frequency Response Dispatchable Solar/Wind Over Generation Mitigation Dispatchable Quick Start Load Shift Peak Load Reduction
23
EPRI/SunSpec California Solar Initiative Smart Inverter Test & Certification Program
Supported by leaders SMA, Fronius SCE, SMUD Sandia, UL Demo full integration Technical controls Market signals Utility networks Enables broad deployment Sets stage for U.S. roll out Harmonizes safety standards
