With something as innately interconnected as a power grid, its not that simple.<p>In the states where they investigated how much value was provided by the rooftop solar, the value was higher again than net metering (e.g. it might save money on uprating grid connection). This means Nevada was effectively taxing rooftop solar and wasn&#x27;t getting the optimum amount installed. With this change they&#x27;ve raised that tax and destroyed even more value.<p>Another specific angle is the retro-activity, this means no consumer in the US can commit to rooftop solar without worrying that all their calculations will be rendered moot, after the install. This puts a big cloud over things.
