Grid Intertie Inverters
• Solar cells generate Direct Current (DC)• The grid operated on Alternating Current (AC) 60 Hz in the US and North America; 50 Hz in Europe and other places.
. The AC to DC conversion is done by a switch mode power supply (SMPS) which interrupts current flow, sending dirty electricity back into the grid

Thermal solar
• No dirty electricity problem with thermal solar• DC solar systems without an inverter or SMPS
have no dirty electricity problem• Dirty electricity is high frequency voltage
transients and harmonics (electrical pollution) contaminating the utility 60 HZ supply

Dirty Electricity
• Makes people and animals ill • Is a potent universal carcinogen• Is responsible for most of the diseases of
civilization• Can be detected as AM radio interference• Can be filtered of of the power supply with
capacitors
