Repairing an off-grid wind and solar electrical system

Low Impact

We recently blogged about a project : ‘rebuilding a home, and changing the surrounding fields from dead agricultural land into an oasis of natural life’ – as well as building an off-grid electrical and heating system. This is basically putting a multi-meter set on DC 10 amps directly across the output of the panels.

Utility-scale solar PV pushes into higher AC voltages

Renewable Energy World

The evolution of high-efficiency solar photovoltaic (PV) string inverters is driving a shift toward higher AC voltages in utility-scale solar applications. Using string inverters in solar plants rated at 20 megawatts and below can be extremely beneficial. Figure 1: a typical utility-scale string inverter application.
