The correct answer is: b) Get credit for excess solar power.
Net metering is a billing arrangement in which customers with solar panels can receive credit on their electric bill for the excess electricity they generate and send back to the grid. This can help to offset the cost of installing solar panels and make them more affordable for homeowners.
Option a) is incorrect because net metering does not allow consumers to sell excess solar power to the grid. Instead, they receive credit on their electric bill.
Option c) is incorrect because net metering does not allow consumers to trade solar power on exchanges. Instead, they receive credit on their electric bill.
Option d) is incorrect because net metering does not allow consumers to store solar power for later use. Instead, they receive credit on their electric bill for the excess electricity they generate and send back to the grid.
