Winter conditions are 5.2Kwh/day and capacities are about 73% of the summer capacities

Solar Spring pumps are true piston pumps and their capacity is linear (+/-10%) to the insolation. To calculate capacity for other latitudes multiply daily insolation as above by the average daily insolation at the site in question, then apply the capacities in the table to the result.
