JinkoSolar targets retail power bills with Sunny 365 solar-storage platform

JinkoSolar has launched “Sunny 365,” a portfolio of integrated solar-plus-storage solutions for commercial and industrial customers. 

The company unveiled the platform on July 23, positioning it as a standardized package for businesses seeking to reduce electricity costs, manage peak demand and simplify the deployment of distributed solar and storage systems. 

The first application model presented under the portfolio targets supermarkets and large retail stores. These facilities typically have sizeable unused rooftop areas, high daytime electricity consumption and load peaks that overlap with higher tariff periods. 

Sunny 365 combines JinkoSolar’s Tiger Neo 3.0 photovoltaic modules with its SunGiga G2 liquid-cooled commercial storage systems. The hardware is linked through an AI-based dispatch system and the Jinko Cloud platform, creating an integrated chain covering solar generation, battery charging, on-site consumption and energy management. 

JinkoSolar said the approach is intended to address several common barriers in the C&I market, including fragmented equipment selection, poor compatibility between PV and storage products, complex commissioning and high operation and maintenance requirements. 

For a large warehouse-style supermarket with around 15,000 square meters of usable rooftop space, the company proposes a 3.3 MW solar array comprising approximately 5,000 Tiger Neo 3.0 modules. JinkoSolar estimates annual generation at around 3.45 GWh, equivalent to 34.5% of the assumed site’s annual electricity consumption. 

The accompanying storage system would provide 2.09 MWh of capacity, using either eight 125 kW/261 kWh SunGiga G2 cabinets or four larger 250 kW/522 kWh units. 

For a medium-sized retail store with about 4,000 square meters of available rooftop area, JinkoSolar proposes an 880-kW PV system with expected annual generation of around 970 MWh, paired with 522 kWh of storage. 

The SunGiga G2 is a liquid-cooled cabinet with 261 kWh of storage capacity and an integrated power conversion system. JinkoSolar said the system supports modular deployment, grid-forming functionality and operation across a wide temperature range. Its larger 522 kWh version uses AI-supported electricity-price forecasting and energy management to optimize charging and discharging schedules. 

The Jinko Cloud platform provides remote monitoring, operating-data visualization, fault diagnosis and preventive maintenance. The company is also offering integrated project design, procurement, installation, commissioning, warranty and after-sales support under the Sunny 365 service model. 

JinkoSolar said the concept has already been deployed at the Ban Chang branch of Thailand’s Robinson retail chain. The site uses a 3.16 MW Tiger Neo 3.0 rooftop PV system for self-consumption and five 215 kWh liquid-cooled storage cabinets for peak shaving and load management.
