Abstract: A photovoltaic module can be constructed from one or more strings, with each of the strings being constructed from a plurality of cascaded solar cells. A connector can electrically connect the strings to one another. The connector can include strain relief connectors that extend between the connector and the strings to help reduce effects caused by thermal expansion.

Abstract: A solar module that includes multiple series-connected sub-circuits is provided. Each sub-circuit may include multiple solar cell strings coupled in parallel. The sub-circuits may be coupled to a junction box that includes bypass diodes. Each of the sub-circuits may be coupled in parallel with a respective bypass diode in the junction box. The sub-circuits may be coupled to the junction box via interconnect buses. The interconnect buses may be routed to an entry point from only one side the junction box to improve manufacturability. The interconnect buses may also include one or more bends to provide strain relief during normal operation of the solar module and during thermal cycling events.
