Most modules in California are tied to the grid, the probable reason is that everybody does it. Grid-tied modules offer features that off-grid systems don’t, and vice-versa. However, homeowners choose to connect their solar system to the grid because they are all familiar with the advantages of a grid-tied module. They don’t know much about the advantages of off-gridding your module so they tend not to use it. Here we will discuss the advantages that both sides bring so you can make an informed decision.
Grid-tied systems are solar modules that are connected to the power grid. They are also called, utility-interactive, grid-intertie, grid-back feeding, and on-grid. They cost much less than the other types to install. They also don’t need a storage device for the energy they generate since the grid will be able to supplement them once the sun goes down, but without a battery, they will not be able to supply electricity when the grid goes down.
When you are tied to the grid, you will be able to lessen the grid’s burden at peak load. Since peak load occurs at noon, when your system is also at peak output, there may be excess energy that goes back to the grid, to be purchased by other consumers. The purchased energy then gets converted to renewable energy credits (REC), which you can use to purchase electricity from the grid when load and price are low, usually at night. This is known as the net energy metering system, which can help you return your investment fully in 4 – 5 years and save a lot of money over the panel’s lifetime.
It only requires a few specialized types of equipment to attach your system to the grid, including a grid-tie inverter and a meter that supports net metering. The utility or the solar company can supply the equipment when the panels are being installed.
A few homeowners choose to have their electricity off-grid, which means they purchase solar panels capable of supplying their entire electricity consumption. Those who are connected to the grid are seldom tempted by the chance to go off-grid because of the reasons mentioned above. And also, the fact that they live near the grid can be a factor as well. Homeowners that live far away from the grid may have no other choice but to go off-grid since overhead transmission lines are very expensive.
Going off-grid requires a lot more equipment than on-grid systems do. Aside from inverters and a compatible meter, it also requires a battery bank, an off-grid inverter, a solar charge controller, and a DC disconnect switch for protection. But even with all these additional expenditures, the appeal of having your house disconnect entirely from the grid and those using fossil fuels is too great for some people that they can’t help but go off-grid.
