Module Architecture

Ten K Solar® cells are connected in a matrix (serial and parallel connections) that allows current to flow through multiple pathways within a module, eliminating any single failure point. Combined with Module Integrated Electronics (MIE), this architecture allows optimization of cell level performance.

Because of the cell level control, partial shading or soiling won’t cripple module production. Ten K’s Modules performance characteristics are fundamentally superior to yesterday’s PV modules which can see output decline to zero with just limited shading, and can develop dangerous hotspots when exposed to reflection. Ten K Modules are designed to outperform yesterday’s PV modules in all conditions.

In addition to the superior performance metrics, Ten K Modules has other characteristics that ensure a long lifetime of energy production. Internal module voltage never exceeds 15 Volts, reducing lifetime stress to cells and interconnections and eliminating the effects of Potential Induced Degradation (PID). Finally, Ten K Modules are constructed with an aluminum backsheet, significantly enhancing their environmental robustness. Yesterday’s PV modules utilize plastic backsheets which are subject to both environmental degradation and water vapor ingress.

Maximum Durability = Unparalleled Reliability

 

Durability has many meanings. Here at Ten K, we get bored with solving shade tolerance challenges so many in the industry have. Instead, we push the limits of what a solar module can do and how well it performs against everyday challenges and even those rare ones.

Join us as we field test a Ten K module versus a conventional module.

Module Integrated Electronics

Located on every Ten K Module is a Module Integrated Electronic which sets the bus voltage between 35-59 volts eliminating high voltage risks. The electronics maintain this output at the optimum efficiency without relying on the inverters to perform MPPT. They monitor the state of the DC bus to provide the optimal input to the inverters and to only export power when an inverter or other device is present while the LED provides a continuous status on the module for easy commissioning and troubleshooting.

NEC Compliant - Designed for Safety

Hot Spots

Impossible with Ten K. Matrix cell wiring means the current from any cell failures will not be blocked internally within the module.

MC Connector Failures

Impossible with Ten K – Not used. Modules use a utility grade tap connector, eliminating the risk of faulty and failed connections, a common failure point on conventional PV systems.

Mismatch Loss

Impossible with Ten K – As cells in serial modules degrade at different rates over time, series wired cells will all operate at the lowest cell wattage. Ten K eliminates this by wiring cells in a parallel matrix, allowing each cell to operate at its peak condition.

Potential Induced Degradation

Impossible with Ten K – Very low internal voltage to module cannot create current leakage.

DC Arc Faults

Impossible with Ten K – The module’s internal voltage stays below 17Vdc where an arc fault is impossible to sustain. The regulated bus voltage coming out of the module remains below 60Vdc and the integrated module electronics automatically disconnect the module from the bus when a fault condition is detected.

String Imbalance

Impossible with Ten K – Each module operates in parallel with all others, eliminating the risk of an individual module negatively impacting the rest of the modules in a string.

Cracked Cells

The robust aluminum backsheet provides exceptional support for the cells greatly reducing the risk of a cracked cell. No Impact on Energy, No Arc Risk.

Diode Failures

No Diodes – Matrix cell wiring and integrated module electronics eliminate the need for diodes in the module. 

Aluminum Backsheet

Since Ten K Modules operate at a low internal voltage it allows for the use of an aluminum backsheet. This backsheet allows Ten K to produce a large form factor module while maintaining a low weight allowing Ten K to deliver the most energy density. It also acts to significantly reduce moisture ingress into the module, one of the largest sources of module performance degradation.

Aluminum diffuses heat 200x better than glass or plastic, keeping the module cooler and performing more efficiently. This enables Ten K to stand behind the best warranty in the industry. It also reduces racking costs as the strength of the module combined with the frame integrated racking allow the module itself to become a component of the racking system.
