Every utility company credits solar energy differently. In Texas' deregulated market, 85% of consumers across the state can pick their retail electric provider (TXU, Reliant, Green Mountain Energy, etc). Make sure you get clarity from yoursales consultant on how your utility provider reports net-metering and if they offer a buyback plan, and whether that buyback plan rolls credits over monthly or is capped monthly, if it's credited at wholesale value or retail value, and whether credits from one meter can feed other meters on the same account.
