Net metering is a billing mechanism that credits solar energy system owners for the electricity they add to the grid. Net metering creates a smoother demand curve for our electricity grids and allows utilities to better manage their peak electricity loads. Net metering also reduces strain on distribution systems and prevents losses in long-distance electricity transmission.
As great as this is for our community, it reduces the utility providers purchase margins on electricity, which is usually bought in bulk. The less power a utility provider buys in bulk, the more expensive it is. As a result, the utility providers are increasing the price of electricity and implementing unfavorable net metering policies for the average American.
It's vital to educate yourself on net metering policy before installing solar energy. Check out your utility providers Distributed Generation manual for net metering policies in your area. If they aren't favorable then, solar batteries can help store energy on property before ever sending it back to the grid.
