The intention is to help consumers and energy suppliers understand current energy consumption
patterns, pricing schemes, and battery utilization strategies. The research supports sustainable
energy practices by addressing the crucial break-even point and assessing ZEV effectiveness. The
study uses modeling, analysis, and simulation to offer insights into how these components interact
and what effect they have on sustainability.
The first objective was to focus on historical energy pricing trends between 2019 and 2023, so the
Solar Cloud Calculator, which is based on the research paper by Carsten Bopp et al (2019), was
used to analyze the financial aspects of solar energy with and without battery storage. The second objective explored two scenarios that showed different financial aspects,
based on a simulation that makes use of adjustable variables and battery discharge algorithms that
evaluates the financial viability.
The study revealed complex relationships between solar power generation, grid costs, energy prices, and
battery use. Above all, feed-in tariffs played a decisive role in the profitability of the system. The
Solar Cloud Calculator
model highlighted situations that favor traditional feed-in methods and identified opportunities for
cost savings. The first scenario challenged assumptions and showed that installing a battery can reduce profit as high feed-in tariffs reduce battery demand. The second scenario emphasized the role of tariff dynamics in assessing the profitability of energy storage systems and highlighted the complex interplay between tariffs, feed-in processes, and projects such
