The Dark Side of Solar Energy

Photovoltaic solar


Grid intertie inverters

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

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

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
