Solar Power and Uninterruptible Power Supply (UPS) are two technologies that are growing rapidly.
The demand for solar energy is mainly driven by the trend towards cheaper solar cells, making it economically
profitable for a larger range of applications. However, solar power has yet to reach grid parity in many
geographical areas, which makes ways to reduce the cost of solar power systems important. This is investigates
the possibility and potential economic synergies of combining solar power with UPS systems, which have been
previously researched only from a purely technical point of view. This is instead evaluates the hypothesis that a
combined solar and UPS system might save additional costs compared to regular grid systems, even in a stable
power grid. The primary reason is that online UPS systems rectifies and inverts all electricity, which means that
solar energy can be delivered to the DC part of the UPS system instead of an AC grid, avoiding the installation
of additional inverters in the solar power system.
