Incorporating solar and wind into the AC grid will be inefficient
Incorporating remote wind and solar, on the other hand, will require an upgraded grid, something entirely different. Our present 345-kilovolt, AC transmission wires can?t do it without unacceptable line losses. We will need to rebuild to 765 kV DC system ? something that could take decades and easily cost several trillion dollars. - Read More

An interesting q on AC/DC kit...
Much of the cost and complexity of PV systems comes from the inverter. The DC power generated has traditionally been converted to AC power, because that became the standard for households years ago. However, most electronic devices (including PCs) run on DC power. This requires a conversion from AC to DC power, which is an added cost & waste of electricity. Would it be possible for you to set up a system that skips the back-and-forth, simply keeping everything on DC power for such remote areas?
