I'm interested in knowing the typical energy pay-back time of a solar photovoltaic panel, in terms of hours operating under an ideal scenario.
Energy pay-back time (EPBT) is usually quoted in terms of years, and often discussed in the context of permanent installations like power stations or rooftop solar. These discussions often include factors like average annual insolation. However, I'm interested in evaluating solar PV devices at the personal scale and might be used while backpacking, canoeing, or other wilderness adventure, where average annual insolation isn't really relevant because the device isn't used every day, and isn't used evenly throughout the year.
