Going solar can be done in a multitude of different ways. It can be done with your system working in conjunction with the Utility Company, entirely separate from the Utility Company or with the ability to operate in both capacities (independent or in combination).
The average system operates in connection to the traditional utility grid. There are a few reasons for this but a major one is that grid absorbs excess production during the day that you then pull back in the evening when the sun isn’t shining and your solar system not producing energy. This configuration allows the homeowner to take advantage of the many benefits of going solar without being exposed to the expense of batteries.
“The integration of batteries gives a home owner independence from the utility grid and a higher level of security if the grid were to fail.”
For those Off-grid applications your solar system will require a or multiple battery banks. These battery banks will hold the energy you produce for use at night or at times of the year when the days are shorter and you need energy beyond that of the days production. The integration of batteries gives a home owner independence from the utility grid and a higher level of security if the grid were to fail.
There are hybrid configurations where the battery(s) itself is intuitive. The battery system is programed to use the grid when it offers the greatest benefits while automatically switching into “Self power” mode if the grid were to go down. This configuration not only offers you the best of both worlds but considering future rate plan changes with the utility company like “Time of Use” gives your system the intelligence to maximize savings.
“This process protects the grid and those working on it from the back feed of your solar system reducing the risk of injury. “
Contrary to popular belief, if the grid were to go down, your non battery backed up system would power down during the outage. This process protects the grid and those working on it from the back feed of your solar system reducing the risk of injury.
If you goal is purely economic, a standard grid tied system or one with an intelligent battery are excellent options to consider with many benefits both economic and environmental. If your objective is total independence you’ll want to integrate battery banks which would insulate you entirely from the grid and give you that security.
So the answer to the question, is, your system can be configured in multiple ways which can lead to an Off-grid application, an On-grid application or an On-grid application that can intuitively power itself independently when circumstances warrant it.
