The solar toolkit compilies global time-series capital costs (CAPEX) and levelized cost of energy (LCOE) data for the solar photovoltaic (PV) industry. The data is presented in an interactive, yet intuitive, interface. Alongside the dataset, a generation cost analyzer is provided and is specifically tailored for the solar PV industry. Within a few minutes, cost and sensitivity analyses can be performed on any solar system irrespective of size, and consequently enabling the comparison of different solar projects based on an ‘apples to apples’ basis easily and effectively
