Grid tie power systems – Commercial and Residential


As energy costs continue to rise, (in Sri Lanka rise by 8% per Year) and as the awareness of global climate change continues to grow, homeowners are flocking to solar as a smart alternative to purchasing power from the utility. you can mitigate your home electrical costs through investment in a solar electric system while also contributing to society`s effort to stem global warming.

What is Grid-tie ?


A basic Grid-Tie system generates electricity when the sun shines, supplying power to your home and sending any excess power back to the utility. DC power produced from your solar array is converted by the Grid-Tie inverter into AC power, which is then sent to your main electrical panel to be used by your household appliances. Any excess power generated is sold back to the utility through “net metering” to reduce your electric bill.

Solar Modules Solar modules mounted on the roof or grounds of your property convert sunlight into DC power.
Inverter This power is sent to a device called an inverter (or power converter) which converts the DC power from the solar modules to AC power identical to that being sent to you from the utility grid.
Electrical Panel Power travels from the inverter to your electrical service panel (your breaker box). The power from the electrical panel will be distributed to any electrical loads in your home.
Utility Meter When excess power is produced by the solar, the power will flow into the grid through your electric meter. This will cause your meter to run backwards gaining you a credit with the utility company.
Utility Grid The utility grid automatically provides electricity when needed - at night and during the day when your demand exceeds your solar production.
