Grid-Tied

A “Grid tied” system is connected with your current utility grid at your meter by use of a “net meter” installed by the utility company, with no batteries installed to store the excess power you produce. The utility grid becomes your energy storage and is monitored by the utility company using Net-metering.

Net-metering

When you own a solar power system your home will frequently produce more energy during the day than you actually need, and you will need more energy at night when your system is not producing. Net-metering simply means that your utility meter flows in both directions. When you are producing energy from your system in excess of your current usage, your meter rolls backward, sending the utility company your surplus power. At night or when your air-conditioner is really working overtime, you seamlessly draw power back from the utility company to meet your energy needs.

Most utility companies in La. no longer cancel out your produced kW hours with the ones you consume from them on a one-for-one basis.  Now you send it to them at "avoided cost" (wholesale), and pull it back at full retail.  That's because they're NOT your friends.

Power-Outages and Grid-Tied Systems

With a strictly grid-tied system you will not continue to have power when utilities are down. It has automatic disconnects built in for safety to eliminate the danger to utility workers of possibly being electrocuted by power generated by your system.

Systems designed with a back-up of batteries can operate safely and automatically switch on when the grid goes down, allowing (depending on size & design) either the entire home or just critical systems such as freezers, fridges etc. to continue to operate.

Monitoring

Many of Solar Louisiana's solar energy systems come with monitoring so you can see real time data on your system right over your Internet connection.
