According to the latest photovoltaic inverter IMSResearch research report predicts that in the 2012-2017 period, the PV inverter service and extended warranty market will grow by 110%. Although PV inverter hardware profit margins being squeezed, but after-sales service market is expected to more than double by 2017, reaching $ 1.7 billion, for the vendor provides a valuable additional source of profits.

Analysis showed that the main cause of this growth will be the driving force for utility-scale PV mounting system in the next five years is expected to be the fastest-growing areas. These PV mounting system usually uses large three-phase inverter, and the inverter will often buy these annual service plans to ensure optimal operation results.

In 2012, 26% of high-power three-phase pure sine wave power inverter are bundled with service plans, by 2017 this figure is expected to grow to 34%. In many cases, the banks and financial institutions will specify inverter service plans as required loan conditions to ensure the effective operation of the PV mounting system, and to ensure that the inverter downtime is minimized.

Although the PV inverter market will show service revenue growth trend, but at the same time, suppliers will face a variety of challenges, including the response to increasingly geographically dispersed photovoltaic markets.

"With the different countries where legislation provides for a different minimum length of the warranty period, suppliers have established service offices in emerging markets to provide customers with sufficient reaction time." IHS analyst CormacGilligan PV explained, "not just focus on the photovoltaic industry industrial inverters manufacturers may have the ability to start the new photovoltaic market to provide after-sales service,

Because they are usually set up in these areas existing business to serve other industries. The PV power inverter with charger single business manufacturers may cooperate with third-party service partners, until they are able in these emerging markets to establish a local service center. "
