Off grid systems are generally installed at locations where grid power is either unavailable or unreliable.
In a grid-tied system any unused excessive energy from the solar panels is feeded back to the grid or the main line. These system require an authorization from electricity companies and even requires special two-way meters installed by them. There are two types of Grid tied system.
a.Grid Feed :This system doesn’t have a battery backup solution.
b.Grid Interactive: This system can store the energy in batteries which could be used only during power outage. You cannot withdraw the power from batteries when grid power is available.
Many people are confused about the Hybrid mechanism of solar systems. The basic working principle of Hybrid system is that it can be used in both ways on-grid and off-grid. But they have other advantages also.
Shield against varying/low feed-in tariff Hybrid system shields a consumer from changing government policies about feed-in tariff by employing self-consumption. Combining energy storage with a grid connection to your property, hybrid systems can provide the flexibility of being able to store the energy you generate during the day instead of feeding it back into the grid - typically at a low feed-in tariff. This energy can then be used in the evening instead of buying power back at a higher price.
Providing Uninterruptable power Buying a hybrid system from Going Solar will mean that when the grid fails, your system will keep going. Our hybrid systems are able to disconnect from the network in the event of a grid interruption (when a standard solar system would shut down). You will be able to continue to run certain appliances from your batteries (and solar during sunlight hours).
Allowing you to outsmart the Utilities A hybrid system can ‘load shift’, meaning the energy that you generate during the day is not wastefully fed back into the grid with minimal financial return to you. The energy is stored and can be used in the evening or whenever you like.
Hybrid systems are fully programmable An advantage of hybrid systems is that they are able to control and balance the available sources of energy
If the power generated by a solar array is insufficient to supply daytime loads as well as charge your batteries, the system can recharge your batteries from the grid when a lower off-peak electricity rate is available.
When your electricity usage goes above a certain level, electricity companies may charge you at a higher rate for this increased level of demand. Hybrid systems can provide ‘peak lopping’ where some stored power can be drawn from the batteries to help balance the power usage.
‘Grid support’ can also be provided by your hybrid system if your grid connection does not have the capacity to supply a load. The hybrid system could supply the extra power. And this may allow you to avoid a costly mains upgrade to your property.
