Advantages of ON-Grid Solar System-4KW solar power system

1. Become Money with Our  Great Sun

"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."

2. Utility Grid as a Virtual Battery

"The electric power grid is in many ways also a battery, without the need for maintenance or replacements, and with much better efficiency rates. In other words, more electricity goes to waste with conventional battery systems."

3. Higher Efficiency 

“With power classes up to 270 Wp and up to 16.5% efficiency it’s the most powerful 60-cell standard module on the market, ideally suited for obtaining maximum yield from smaller rooftop areas.”
