As the LPR-200 and TSAWR loggers step down the solar voltage to 12v, a 20 Watt solar panel realistically provides 9 Watts to a seismic station. Theoretically, 1 hour and 9 minutes of sun per day should keep the battery charge stable. However, in practice, 1 hour and 30 minutes of full sunlight for a 20 Watt solar panel is required to keep these stations at a stable charge (this was tested over a 5 day period under Canberra sun in spring) 22 22 23 -**Note**: It is important to understand 2 main limitations of the solar component of these seismic stations. First, the voltage output of most solar panels will drop significantly if even a small portion of the panel is shaded. This is why 'full' sun is a requirement. Second, 1 hour and 30 minutes of full sun per day will not alwaysbe achieved. The sunniest possible location for a seismic station is always ideal.23 +**Note**: It is important to understand 2 main limitations of the solar component of these seismic stations. First, the voltage output of most solar panels will drop significantly if even a small portion of the panel is shaded. This is why 'full' sun is a requirement.
