6 FAQs about [Photovoltaic inverter maintenance risk identification]

Do technical risks affect PV investments?

Since there are no commercial risk modelling tools available in the market which allow analysing technical failures and their economic impact over the lifecycle of PV systems, a customised financial modelling tool has been developed based on the PV project cash flow to measure the impact of technical risks on PV investments (Figure 7).

What is photovoltaic risk analysis?

Photovoltaic (PV) risk analysis serves to identify and reduce the risks associated with investments in PV projects. The key challenge in reacting to failures or avoiding them at a reasonable cost is the ability to quantify and manage the various risks.

How do we assess technical risks in PV power systems?

Semi-quantitative and quantitative methodologies are introduced to assess technical risks in PV power systems and provide examples of common technical risks described and rated in the new created PV failure fact sheets (PVFS).

What is PV risk analysis?

PV risk analysis serves to identify and reduce the risks associated with investments in PV projects. The key challenge in reacting to failures or avoiding them at a reasonable cost is the ability to quantify and manage the various risks.

Why is risk identification important in PV Financial modelling?

Risk Identification in PV financial modelling, improper inputs (costs, yield, e.g.) will inevitably result in incorrect calculations of revenue, cost, cash flow etc, thus give inaccurate assessment of the investment-worthiness of a PV project.

Are solar PV systems risky?

system. These data come from TEP managers, databases and documents. Our preliminary risk analysis indicated that the greatest risk for an electric power grid with solar PV systems was weather causing the solar panels to receive less sunlight than expected.
