Exotic Solar Technologies
Published in Anco S. Blazev, Solar Technologies for the 21st Century, 2021
Balance of system (BOS) components, such as supporting frames, trackers, combiner boxes, inverters, switching networks, transformers, wiring connectors, etc. have also gone through a lot of changes in the past. Comparing the analog inverters of the 1970s with the super-inverters of today we see an almost vertical line of progress. The same is true for the other components, so it suffices to say that BOS components are the most reliable, or at least the most predictable, part of any solar installation today.
Solar Energy

The solar cell module or the PV system is the heart of the solar electric system. It converts solar radiation directly into electricity. The power output of the solar cell increases as solar radiation is increased, more or less in direct proportion. Note that a solar PV system is more sensitive to direct solar radiation than diffuse radiation. The balance of system (BOS) is comprised of the other components listed above besides the solar PV system.
PV Power Generation

Balance of system (BOS) is a generic term that describes all components needed to install, adjust and control a PV system, except the PV modules. This includes wiring, switches, support racks, inverters, and batteries in off-grid systems. Land, labor and O&M expenses and components are usually not included in the BOS calculations. See Table 5-8.

The Levelised Cost Of Electricity (LCOE) produced by the PV plant is also calculated by considering the capital cost and life time of different components (Table 5). The discount rate for the year of installation and procurement of PV plant components (d = 8.6%) is taken into account. Now by considering the d value given life time of components, the capital costs (Rs.) of different components (solar panels, inverter and BOS) are converted to an annualised cost (Rs.). The balance of system (BOS) encompasses all components of a PV system other than the PV panels. This includes wiring, switches, a mounting system, services, etc.
