Global Solar Atlas

The Global Solar Atlas provides a summary of solar power potential and solar resources globally. It is provided by the World Bank Group as a free service to governments, developers and the general public, and allows users to quickly obtain data and carry out a simple electricity output calculation for any location covered by the solar resource database.

How much electricity do solar panels produce?

Solar panels generate electricity during the day. They generate more electricity when the sun shines directly on the solar panels. Figure 1 shows PV generation in watts for a solar PV system on 11 July 2020, when it was sunny throughout the day and on 13 July when there was a mixture of sun and cloud.

Before the Clean Export Guarantee was introduced in 2022, homes fitted with solar panels exported surplus electricity to the national grid for free. Therefore, investing in a storage battery to save up power for a later date made sense.

Solar explained Photovoltaics and electricity

PV panels vary in size and in the amount of electricity they can produce. Electricity-generating capacity for PV panels increases with the number of cells in the panel or in the surface area of the panel. PV panels can be connected in groups to form a PV array. A PV array can be composed of as few as two PV panels to hundreds of PV panels.

Understanding Solar Photovoltaic System Performance

As of 2020, the federal government has installed more than 3,000 solar photovoltaic (PV) systems. PV systems can have 20- to 30-year life spans. As these systems age, their performance can be optimized through proper operations and maintenance (O&M). This
