Powerful solar panels up to 450WP with multi-wire technology and 144 halfcut monocrystalline cells.


Autarco's MHH series solar panels use 144 halfcut monocrystalline PERC cells with advanced multi-wire technology to deliver higher effeciency without compromising on reliability at a rated voltage of 1500V DC. The ability to withstand mechanical loads of up to 5400 Pa, combined with superior resistance to sand, salt and ammonia delivers long lasting performance in even the harshest environments.

Autarco's total-solution


  • Insured kWh guarantee: Our total solution approach allows us to insure kWh performance, when yields are lower than promised the foundation compensates in cash.
  • Reduce fire risk: The entire Autarco solution is provided with Staubli MC4 connectors for reduced fire risk together with our inverter integrated AFCI detection.
  • System design software: Helios software ensures mounting materials are automatically compatible with new MHI dimensions.
