6 FAQs about [Photovoltaic and energy storage matching]

Does energy matching improve PV production and load matching?

Using the Energy matching chart, the matching between PV production and load presented in previous studies is graphically analyzed and compared. Furthermore, the potentials for the two most common measures for improving the matching, namely energy storage and load shifting, are investigated.

Does PV electricity production match electric load?

In this paper, the matching between PV electricity production and electric load was visualized and analyzed by using the Energy matching chart. The Energy matching chart allows for a more extensive comparison of buildings with on-site electricity supply than single value measures.

What is a load matching indicator for photovoltaic energy supply?

For on-site renewable energy supply, such as photovoltaic (PV) electricity generation, an important issue is the daily and seasonal matching between on-site supply and demand. The matching potential is frequently expressed using the load matching indicators such as self-sufficiency and self-consumption.

How to visualize PV-load matching potential?

The matching potential is frequently expressed using the load matching indicators such as self-sufficiency and self-consumption. This paper presents the Energy matching chart, which is a novel graphical approach to visualize the PV-load matching.

How does energy matching work?

When the matching is improved by using for example battery storage or DSM, the system follows a straight line defined by the relationship between the production and the consumption. The Energy matching chart also visualizes if the building is a net producer, net zero, or net consumer of electricity.

What is energy matching chart?

Hence, the Energy matching chart can be used to assess the improvements of a solution in terms of time-wise matching by increasing the self-consumption and self-sufficiency without changing the total production and load, and it can also be used to assess the dimensioning of a PV production system through the P/L ratio.
