Effect of PV on-grid (quality, voltage, stability)

[QUOTE="anorlunda, post: 5488625, member: 455902"] PV is a tiny portion of the connected generation in the USA. 0.2% if my memory is correct. Something that small has a negligible effect on the bulk power grid, no matter what it does. Local power distribution, say on your street, is a different matter. Distributed generation (DG) makes it more difficult to design the protective relaying required to keep the local power supply safe and reliable. Your questions are all mixed up. You ask about the grid, but then about your own equipment. Electrical circuits are [U]not[/U] worn out by time varying voltages and currents. Corrosion is not affected by voltages and currents, unless there is a galvanic current leaking to earth. Contaminants in the air are the principle cause of corrosion. I live on a boat in salt water. Salt in the air is a constant enemy of my electrical connections. [/QUOTE]
