Ruff Realizes Asset Management and Securitization of Distributed PV Stations

In the past, a distributed power station was just an alternative product that provided free electricity for enterprises or families based on the principle of photovoltaic power generation. Although the Renewable Energy Law of the People’s Republic of China was implemented ten years ago, most distributed PV stations today still implement the model of “self-supply + grid connection for excess power”.

Thanks to the expanding PV market and national subsidies for renewable energy, the distributed PV station has evolved from a power plant built for self-supply by the owner to a commercialized financial product of asset management and securitization. In other words, the power generation benefits of PV stations can be securitized for transactions.

During the transformation of the business model, the PV station’s transparency and data consistency have to be guaranteed. This means that consumers that have bought equity in the PV station have the right to access its real-time power generation data and benefits to validate their own investment interests. Meanwhile, steps must be taken to make sure the PV station’s core data and value data are not tampered with and are shared with all equity holders for data consistency. Ruff’s IoT connection and ability to upload data to the blockchain can help the owner and consumers achieve asset management and securitization for distributed PV stations.

  • IoT connection realizes real-time monitoring and management of station data

To begin, Ruff installs an independently developed IoT smart gateway (collector) at the station. One end of the collector is connected to the inverter which is able to count the station’s electricity production, albeit inaccurately, so the collector can monitor the station’s operating status and determine the source and reason of failures. The other end of the collector is connected to the ammeter to directly read how much electricity is generated, thus avoiding discrepancies between the inverter and the ammeter. Data collected by the collector is then transmitted to the cloud. In this process, the Ruff collector conducts the first local edge computation and uploads power generation data required by the customers. Only useful generation data is uploaded to the cloud and blockchain to reduce storage waste.

After the power generation data is uploaded to the cloud and Ruff’s public blockchain, customers can develop visual mobile apps based on Ruff OS. This way, both owners and consumers can view the PV station’s power generation data in real-time on their cellphone, including efficiency, energy conservation, and estimated emissions reduction information. Thus, asset management and securitization of the PV station is realized.

  • Transmitting information to the blockchain provides consistency and transparency in station data

For consumers who have bought equity in the station, real-time monitoring of station data is just the first step. The core issue that Ruff wants to solve through blockchain technology is how to make sure the data you see is trustworthy and reliable. Presently, all distributed PV stations store their data in a centralized cloud, so it is easy for someone to tamper with the power generation data and siphon the benefits. Therefore, when station data is uploaded to the cloud, sensitive core and value data, which concerns the consumers’ investment interests, will be transmitted to the blockchain. This means that all core data and value data of the station will be open to the consumers, who can consequently access more transparent and trustworthy product information.

At the same time, transparent and consistent data provides highly objective and authentic references for PV station investors. This reduces cost during the front-end inspection and evaluation of every distributed power station, thus more efficiently estimating key information such as the station’s annualized return and return on investment.

For distributed PV stations, the combination of IoT and blockchain technology provides a new business model and realizes secure transaction of assets such as equipment and product. The value derived from the assets can be traded and enterprises can issue collective trust plans of financial lease based on the state of the IoT equipment and assets. In this way, the ownership and usufruct of the assets are separated, self-owned capital is occupied less, and relevant charges can be collected, giving birth to a new profitability model featuring shorter periods and quick returns.
