The service life of Chint photovoltaic panels

Why should you choose Chint power for a photovoltaic inverter & energy storage converter?

Look at the development with data and prove the strength with performance.Chint power is committed to providing photovoltaic inverter and energy storage converter with excellent performance.

Why is Chint power important?

Under the goal of "carbon neutralization, carbon peak", new energy is an indispensable help to achieve the goal of carbon neutrality. Chint power is also actively changing and innovating, making more solid and positive efforts for the low-carbon transformation of energy with high-quality services and reliable products.

How long does a PV module last?

Therefore, for economic viability of PV projects, most PV module manufacturers guarantee a power reduction of less than 20%, referenced at standard test conditions (STC), modules tested under 25°C temperatures, 1000 W/m2, irradi-ance, and air mass 1.5, within 25-30 years of operation.

When does a PV system end-of-life?

Depending on the economic situation of a specific PV system, the end-of-life can be reached due to changing contractual conditions (e.g., changing electricity prices) or if it comes eco-nomically attractive to replace PV modules by new ones with higher efficiency.

Why do we need reliable service lifetime prediction of PV modules & components?

For example, reliable service lifetime predictions aid: PV module and components manu-facturers to provide more realistic warranties, PV project investors to make good financial decisions, and consumers to increase their trust in PV energy. More reliable service lifetime prediction of PV modules and components is still quite a challenge.

What is the end of functional life of a PV module?

Then the functional end of life is reached. From a purely technical viewpoint, the end of functional life of a PV module is only reached when the module does not deliver any electricity at all or electrical safety is not guaranteed anymore.
