Abstract: Methods and systems are described herein for a decision layer of a multi-layer data platform. The decision layer may process application queries and serve the queries based on a dataset of previously generated and indexed data or, as a last resort, queries the blockchain node directly. Using indexed blockchain data to serve application queries reduces latency and downtime of traditional systems that direct queries to blockchain nodes immediately. Furthermore, the decision layer overcomes high latency and downtime issues associated with a pool of load-balanced nodes by reducing the number of direct queries to a blockchain. When applications rely on data directly queried from a blockchain, they are susceptible to limited availability, a problem that the decision layer mitigates with indexed and updated blockchain data.

Abstract: A method for installing a maximum power point tracking (MPPT) controller is provided. The method includes acquiring an occlusion area proportion of a photovoltaic string in a photovoltaic system, optimizing the occlusion area proportion to generate a target occlusion area proportion, determining a target position from the photovoltaic string according to the target occlusion area proportion, and installing the MPPT controller at the target position.
