Abstract
This paper analyses the degradation that is experienced by different types of Li-ion batteries when used as home solar storage systems controlled to minimize the electricity bill of the corresponding household. Simulating the annual operation of photovoltaic (PV) residential systems with batteries at different locations was undertaken to perform the study and it uses actual consumption values and real PV production profiles, as well as validated semi-empirical ageing models of the batteries. Therefore, the work provides a realistic prognosis around the lifetime expectancies for the different Li-ion chemistries.
Highlights
PV technology has become the most important power generation source worldwide in terms of added capacity per year since 2016, overtaking wind power, which was the leading technology up to [1]
The analysis of the lifetime expectancy that is offered by the different types of Li-ion batteries has been performed by means of simulations while using MATLAB®
This paper introduces the lifetime expectancy for four different types of Li-ion batteries implemented as home solar storage systems
Summary
PV technology has become the most important power generation source worldwide in terms of added capacity per year since 2016, overtaking wind power, which was the leading technology up to [1]. This is because such systems allow for reducing the intermittency of the local production, stabilizing the low voltage grid, and make it possible to optimize the energy bill for the installation owners and even provide extended supply security, which cannot be taken for granted everywhere In this way, some specialized consultants indicate that out of the 4 GW of batteries with an 8 GWh capacity to be deployed globally in 2019 (with calculations to achieve 15 GW with a 44 GWh capacity in 2024 and between 180 and 420 GWh in 2030), more than half could be distributed [8], i.e., behind the meter PV residential systems with batteries, known as Energies 2020, 13, 568; doi:10.3390/en13030568 www.mdpi.com/journal/energies home solar storage systems. In sense, consolidating its position the second-largest market after Germany and Spain arethis clearly settotobe spread across Europe
