PV inverter accounts for component cost

How much does a PV inverter cost?

They expect a cost reduction in PV inverters of about one-third in the coming decade. Back in 2008, the specific system price was 3260€ per each kWp for a 1.4 MW-sized PV plant with crystalline silicon PV modules with a cost share for BOS of only 24%, including 9% for installation and 7% for a central inverter.

What is a PV inverter?

An inverter is integrated as an indispensable component to the PV systems in order to convert the DC electricity of the PV module output into AC electricity for the electric grid.

Why is a photovoltaic plant more expensive than a PV module?

Today the expenses related to all the other components in a photovoltaic (PV) plant beside the PV modules are higher than the PV module cost itself. Thus more attention is paid to inverters, mounting structures and planning aspects as well as operation and maintenance costs (O&M) to further reduce the total costs of PV electricity production.

Should a rooftop solar PV system be included in a C&I space?

The main component cost like PV modules, Inverters, construction, mounting and structures all scale similarly. Including energy storage to a rooftop solar PV system in the C&I space can effectively double the system costs and should only be considered if full energy security is the goal.

What contributes to the cost of a rooftop solar PV system?

With the increased interest in rooftop solar PV in the C&I sector it is valuable to understand what contributes towards the cost of a system, whether it’s a turnkey or PPA project. The PV modules account for roughly 47% of the cost of the system, the largest contributor in the total system cost.

Is there a kit inverter and PV module combination?

The kit inverter and PV modules were part of these components lists considered in the lineal programming model. The result of the model shows that there exists another inverter and PV module combination that could be less expensive in the same store.
