Solid-state Relay Sector: Growth Drivers and Challenges

Growth Drivers

  • Growing Utilization of Solid-state Relay in Remote Control System: Small current signals are frequently required by remote control systems for controlling high-power machinery including electric motors, pulse valves, and other machinery. Solid state relays are frequently employed in remote control systems to serve as electronic switching components without mechanical contacts since they have many great benefits, including high reliability, flexible control, no spark, no noise, fast switching, high operating frequency, high durability, and strong anti-interference ability.
  • Rising Need to Control Cooling/Heating System: Solid-state relays (SSR), thyristor modules (SCR modules), and AC contactors are typically among the three techniques employed to control heating and cooling systems. Solid-state relays and SCR modules are both widely used in cooling and heating equipment nowadays; however, SCR modules are less common since they are more expensive. As a result, solid-state relays are more frequently used in heating and cooling equipment including electric ovens, coffee makers, food vending machines, griddles, fryers, air conditioners, refrigerators, and so on.
  • Surge in Adoption of Integrated Thermal Protection System: Solid-state relays (SSRs) produce heat when they operate. The component may become damaged from overheating brought on by a continual high level of operation, which could further lead to a halt in production. In order to prevent such occurrences, solid state relays are being manufactured with integrated thermal protection mechanisms that shut off the circuit in the event of overheating, shielding both the component and the parent system from any potential damage or shut down.


  • High Cost of Solid-state Relay - A major obstacle to the market's expansion in the near future is anticipated to be the price of purchasing a solid-state relay, which is much more than the cost of an electromechanical relay. However, the solid-state relay market will expand tremendously as a result of the decrease in procurement costs. But although electromechanical relays are less expensive, the total cost of various maintenance tasks over time, including downtime, repair costs, and manual labor, will roughly be comparable to that of solid-state relays.
  • Tough to Manage the System
  • Lack of Efficiency

Solid-state Relay Industry- Regional Synopsis

APAC Market Forecast

The Asia Pacific solid-state relay market is expected to grow at a share of 35% over the forecast period. This growth could be attributed to growing rail projects. For instance, as of April 1, 2022, there were 183 new line projects underway across the Indian Railways, totaling 20,937 km (including elevated railway track/corridor) and costing roughly USD 0.04 billion. Of these, 2,831 km (or roughly USD 0.0113) had been completed and commissioned as of March 2022. Hence, the demand for solid state relay is growing since, it is extensively used in rail to make them function well in extreme condition.

North American Market Analysis

The solid-state relay market in North America is also expected to have significant growth over the forecast period. This growth could be owing to a rise in the number of people travelling by plane. Solid-state relay is extensively used in lighting aircraft runways since it provides multiple lighting solutions. Therefore, since airplane passenger is growing the demand for construction of aircraft runway is also rising further boosting market growth in this region.
