The SP90-L 90 W solar panel is a photovoltaic power source capable of recharging batteries. It is used in CO2 Bowen Ratio, CO2 Eddy Covariance, or other systems that require high-power solar panels. The SP90 allows unattended operation of systems in remote locations, far from ac electrical sources.
This solar panel needs to be used with either a 18529 Morningstar SunSaver regulator or a CH200 Smart Charge Controller.
In the image, the SP90-L is shown with a 31107 Extended Mounting Kit.Read More
The SP90 includes the 31107 Extended Mounting Kit for attaching the solar panel to a Campbell Scientific tripod or tower. The 31107 positions the solar panel approximately 25 cm (10 in.) from the tripod or tower, which reduces shadows from other components and guy wires. The zenith angle indicator and the slotted supports simplify installation. The 31107 began shipping with the solar panel in October 2014. This kit may be purchased separately to retrofit existing solar panels.
One SP90 can be connected to the SOLAR charge input of the CH200 or 18529 SunSaver regulator to provide a peak charge of 90 W. Two SP90 solar panels can be wired in parallel to the charge inputs of the SunSaver 18529 regulator to provide a peak charge of 180 W.
Note: Regulators must be housed in an environmental enclosure.
The 18529 Morning Star SunSaver limits charging current to approximately 10 A, has a quiescent current drain of approximately 8 mA, and can charge sealed batteries such as our BP12, BP24, and BP84 or flooded batteries.
The CH200 limits charging current to approximately 3.6 A, has a quiescent current drain of only 0.3 mA and can precisely charge the following battery families: EnerSys Genesis NP Series (includes our BP12 and BP24), EnerSys Cyclone Series, Concorde Sun Xtender Series (includes our BP84 and PS84) or a custom battery.
