Solar problem in the Sahara?. Our brand new Tenesol TE2000 solar panels were underperforming, giving only 27.4 open circuit volts instead of 33, which wasn’t enough to charge up our system. Even in the Sahara where sun is never a scarce commodity. And solar is important to us because we keep Abigail’s insulin in our fridge to control her diabetes and no fridge means no insulin which means no more Sahara. Time to go north anyway. We had a technician contact Tenesol but they have not been able to help us yet.
Quick fix? I wired the panels in series rather than parallel (technicians suggestion). That doubles our voltage which I hope our system will handle, and it gives us the load amps of a single panel. If anyone out there thinks this is a crazy solution, please let me know.
