Solar Grid Tie System
A grid-tie system is far more reliable option, as you have access for two power sources. One source is solar power and another is electric supply from grid. Best feature is one can use net metering.
With net metering we can even earn money by generating excess power than our requirement. Grid tie system is most cost-effective option. It not only saves electricity bill but one can even earn money from it. Grid tie system is best way of power utilization especially in areas where saving electricity bill is urge of time.
Your solar panels will often generate more electricity than what you are capable of consuming. With net metering, homeowners can put this excess electricity onto the utility grid instead of storing it themselves with batteries.
Net metering (or feed-in tariff schemes in some countries) play an important role in how solar power is incentivized. Without it, residential solar systems would be much less feasible from a financial point of view.
