Are you looking for solar on grid systems? However, the confusion between choosing off-grid and on-grid systems keep lingering you? Then take a look at the differences between solar on grid systems and solar off grid systems to decide the right option for you.
Differences Between Solar Off-Grid and Solar On-Grid Systems
#1: Access to Electricity
Electricity Access with Solar Off-Grid System
With an solar off grid system you will be completely relying on the sun and energy stored in the batteries for powering your home or business. Off grid system do not have a generator and hence you can only have access to electricity when the sun is shining and when you are pulling electricity generated previously by your solar system from solar storage device.
Electricity Access with Solar On-Grid System
When you choose a solar on grid system you will have access to electricity always unless the grid goes down. In case your on-grid system is not producing any electricity or enough electricity for powering devices, machines and more then you can pull energy from the utility grid to supplement it.
#2: Excess Production
Excess Production with Solar Off-Grid System
When your solar off grid system produces excessive electricity that you use or require during day time it is sent to the batteries for storage. This stored energy can be used when the system stops producing electricity such as during night or cloudy weather. However, when the weather is abnormally cloudy for several days in a row, your off grid system may not be able to produce enough electricity for charging up the batteries and fulfil your energy requirements.
Excess Production with Solar On-Grid System
In case of a solar on grid system the excess energy produced you can send it to the grid which will further be compensated for that electricity instead of sending it to the batteries. This energy on the grid can be drawn off the grid you will be drawing on those credits to get your electricity rack up charges on your electricity bill. Solar on grid system has distinct advantage over off grid systems due to net metering.
#3: Power Outages
Power Outages with Solar Off-Grid Systems
When you use a solar off grid system and there is a bad storm that knocks out the power, the system still continues to operate. Hence, you won’t be noticing changes in the access to electricity.
Power Outages with Solar On Grid Systems
When you are using a solar on grid system and the power suddenly goes off due to bad weather, the electricity will also go off unless you are using an system with battery backup. Although it is a disadvantage of on grid system over off grid system, but adding backup batteries is a great option.
#4: Electricity Bills
Electricity Bills with a Solar Off-Grid System
With a solar off grid system you will not receive any electricity bill at all. However, still off grid systems are often more expensive due to additional equipment such as batteries that are required for making it workable.
Electricity Bills with a Solar On Grid System
You receive minimal charges on your electricity bill when you are using solar on grid systems even when your solar system provides you 100% electricity.
