What is the breakdown of solar energy losses?

Important: The breakdown of losses shows absolute loss values (non-cumulative). This table details monthly energy losses throughout the PV system, starting from the initial solar input and tracking reductions at each stage:

How does a storage system lose energy?

They pass through cables, electrical components (such as inverters), and finally through the batteries of your storage system. At each obstacle or resistance, they release a small amount of their energy – this is when conversion losses occur, similar to the way people lose energy when overcoming obstacles.

How much energy does a storage system use?

This means 340 kWh conversion losses and 131 kWh losses due to self-consumption. The energy available from the storage system minus the losses is then 2,000 - 340 - 131 = 1,529 kWh. In other words, the efficiency in this year is around 76.5 per cent. In principle, a higher degree of efficiency is desirable, as less energy is lost on the way.

Does a 100% efficient energy storage system exist?

A 100% efficient system does not exist. Even with premium components, some power is always lost during the charging and discharging cycle. These losses occur across different components of the energy storage system (ESS). Chart 1: Breakdown of Energy Losses in a Lithium-Based ESS

Where can I find a breakdown of my PV system losses?

A detailed breakdown of your PV system losses is provided on the PV system losses page. For better data analysis, the page is further categorized into yearly and monthly losses, respectively.

What causes solar panels to lose power?

Shading Losses: Occur due to partial or complete shading of solar panels when obstructions block solar irradiance from reaching them. Soiling Losses: Caused by accumulation of dust and dirt on solar panel surfaces. Angular Losses: Result from sunlight incidence angles on solar panels.
