Now here is where your solar installation gets very interesting. There are different types of residential solar systems that you can choose from. For instance, if you choose a solar power grid installation, a bi-directional meter will be installed by your solar panel contractor. This meter tracks both energy in and out of your home. This is needed because there will be times that your panels produce more energy than you can consume at one time. When this happens, the energy your solar powered roof has supplied will go back out to the grid for other homes and businesses to utilize. In the meantime, you will receive a credit for the energy you are passing back to the grid. For you, it is a win-win situation; you are powering your home for free through the sun, and in case you ever do need to rely on power from the grid, you have access to it, often times for free because of the credits you have accumulated! This system is called a residential solar power grid installation and is the most common and cost effective system due to the minimal number of components needed.
A differing system is referred to as residential solar power grid installation with battery backup. With this solar installation by your solar provider, your system is installed with the same size array of solar cells, but instead of feeding excess current back into the power grid, a battery is installed to store the energy for later use in your home. If you like the idea of off-the-grid energy, but still want the capability to use grid power, the battery backup system is right for you. In this scenario, your excess energy is stored in your battery so your home may draw from it as needed. In the meantime, you are still able to draw from the power grid if needed during a period when the panels cannot receive much sunlight and the batteries are empty.
Finally, if you want complete self-sufficiency, there is an off-grid solar power system you can consider for your solar panel installation. In this scenario, you are what the name states, OFF the grid. It is essential that the solar panel installation includes a backup battery with the system. This ensures a balance during periods of excess demand or when minimal sunlight is available. These systems can also by coupled with a generator for times of emergency. The generator will automatically turn on in cases of excessive demand when the batteries have been exhausted.
There are many options available to you when considering your solar installation options. The right solar panel contractor can make all the difference when it comes to a smooth and straightforward transition for your energy needs.
