Abstract: A high efficiency configuration for a solar cell module comprises solar cells arranged in an overlapping shingled manner and conductively bonded to each other in their overlapping regions to form super cells, which may be arranged to efficiently use the area of the solar module.

Abstract: Data sharding partitions data associated with an application into multiple shards in which each shard stores a subset of the data. A shard is further divided into multiple microshards in which each microshard contains a subset of the shard data. A set of microshards are assigned to a specified shard. The assignment of microshards can change, e.g., when new shards are added and microshards are migrated from one shard to another shard. A microshard map, which indicates a mapping between the microshards and shards, is updated automatically when the assignments change. After identifying the shard to which a specified microshard is assigned using the microshard map, a data access request from a client device is automatically forwarded to the appropriate shard. Because data can be accessed efficiently regardless of whether the number of shards changes, the data sharding facilitates provisioning of the shards on a need basis.

Abstract: The disclosure is directed to data replication in a distributed computing system. The system ensures a read-after-write consistency for the replicated data by associating the write requests with unique version numbers, and using them to obtain the data. A server associates a write request with a unique version number, and returns the version number to a client, which can use it in a subsequent read request for the data. On receiving a read request for a first data, the server extracts the version number from the request and ensures a specified write request associated with the version number is processed prior to obtaining the data. If the specified write request is processed, the server obtains the data and returns it to the client, else the server processes the pending write requests up until the version number and then the specified write request, and returns the specified data to the client.

Abstract: The disclosure is directed to data replication in a distributed computing system. The data, e.g., received from a client, is replicated to a first set of servers (“sync replica set”) synchronously and to a second set of servers asynchronously (“async tree”). A server can be a primary, secondary or a follower server. A sync replica set includes a primary server and one or more secondary servers. The async tree includes multiple follower servers deployed in a tree structure. A primary server can replicate the data to the secondary servers synchronously, and the secondary servers can replicate the data to one or more follower servers, e.g., a root node of the async tree, asynchronously. The root node then replicates the data to children of the root node, which then replicate to their children and so on until the leaf nodes of the async tree receive the data.
