<div>Hi, Wrenchies~</div><div></div><div>Kindlyeducate me regardingPVbehavior when the load is a resistor. Here's a hypothetical situation:</div><div></div><div>* Eight 250 watt PV modules (60 cells per module), all connected in series for "peak" ratings of 240 volts DC & 8.3 amps</div>
<div></div><div>*Lab type cell temperature &illumination so that the eight would truly pump 2,000 watts<strong><em>into an idealload</em></strong></div><div></div><div>* A 240 volt AC heating element designed for 2,000 watt heat dissipation at 240 volts AC...that's about 29 ohms resistance for the heat element</div>
<div></div><div>* Connect the PV string to the heat element, with nothing in betweenexcept a fused disconnect.</div><div></div><div>In the above situation, would the resistance of the heating element be all that's needed to force the PV array to operate near the "peak" wattage?</div>
<div>Would the heater actuallyget 2,000 watts to turn into heat?</div><div></div><div>+++++++++++++++++++++++++++</div><div></div><div>Now consider the same cell temperature but half the illumination. That's similar voltage but half the amps atpeak wattage. If this is sent into the same29 ohm</div>
<div>resistor--again with no intervening electronics, could we count on 1000 watts of heat?</div><div></div><div>If the answerscome up "no", would the powerthroughput be helped bya SolarConverters styleMPPT pump controller (Linear Current Booster kinda thing),assuming thatone could be found to operatein the240 volt range?</div>
