Look at the 3 Main Types of Solar Power Systems
So, we’ve given you a rundown on what Solar Power is and what are included in a Solar Power System. Now, we’ll tell you more about the Types of Solar Power Systems. These are the different configurations that you can choose from when trying to setup your solar panel installation. There are three main types:
1. On-grid or Grid-Tied System
This is the most basic setup that you can begin with. It’s called on-grid because even though you’re using solar panels, you’re still connected to the power grid. If you’re generating power from your solar panels, you don’t have to rely on the grid. And your excess power can be sent back to the grid in exchange for credits (in some states), called net metering. But at night, there’s significantly less solar power, therefore you’re going to take power from the grid (and have to be billed for it). However, the downside to a grid-tie system is that when there’s a power outage, your solar panels are also affected. No power at all. Still, it’s popular because you only need to buy the basic essentials to start your solar power.
2. Off-Grid System
An off-grid system is the extreme opposite of an on-grid. Here, you are no longer connected to the power grid. You solar panels effectively work as your own, exclusive power plant. The key component here is a full-service battery set-up that serves as a storage for excess solar power generated during the day. This collected power can sustain you through the night. You do have an option to connect a generator to your system for added power supply. This option is ideal if you do not have access to a power grid like in remote areas. This may be costly in terms of the capacity of the battery that you need for your requirements, in addition to the optional generator and its accompanying fuel.
3. Hybrid System
In essence, it’s like having two sources of electrical power at your disposal. It’s just like a grid-tied system, with the exception of having a continuous source of power because of the addition of batteries or extra storage. With a hybrid system, solar power flows to your house when you need it while flowing to the battery and to the grid if it’s in excess. When there’s a blackout, you can use the power stored in your batteries to provide electricity to your home. This may very well be the most expensive option because of the addition of the battery and the charge controller. Batteries can be expensive but if you really need to have power all the time, maybe because of life-saving equipment, then this may be your only choice.
You may now have an inkling as to what solar power system you’re thinking of. If you want minimal cash out but still have better savings, an on-grid system may be acceptable. If you’re in a remote area with no access to a power grid, your only choice is an off-grid setup. The hybrid system is best if you’re willing to spend for the most complete solar power setup.
