If I set up a solar array I need to place the panels as close to the battery bank as possible to reduce transmission losses. I should also look at wiring in series to up voltage to also reduce transmission losses. Otherwise I have to sink a ton of money into cable cost.
Industry-scale solar farms take their power output up to thousands of volts to transmit electricity over huge distances without much loss. Can something be learned from this for small scale? Is there a transmission inverter available to the public at a smaller scale? I'm imagining someone with a decent amount of land whose house is in the shade and has a nice sunny spot 200ft away. It'd be nice if there was an inverter that can take my 48VDC or similar from my panels and switch it to 100-200VAC to travel a distance to my house. Sure, there would be some inefficiency and loss from said inverter (plus you'd presumably need to rectify it back to DC to charge batteries, more inefficiency). But you could use a lot longer and thinner cable for transmission. In some cases benefits might outweigh cost. Anyone done this before?
