This graph illustrates the output power levels of a SunSaver MPPT controller—comparing a 200W module to a
240W module—operating on a clear & sunny day at STC maximum power (Pmp).
 Though the power being delivered to the battery is limited to 200W and the red area at the top of the
production curve is lost, the larger module is harvesting more energy, as shown in green.
 The larger module will provide better production with no power-shaving early and late in the day as
compared to a smaller module.
 In this case almost twice as much energy is gained (green area) than lost (red area) with 12.5% more
energy available to charge the batteries than the 200W module.
