WHAT IS A GRID TIE SOLAR SYSTEM?


SMA grid connect home FLOW 1It is a photovoltaic (PV) system interacting with the main grid, and can be with or without batteries, it has an inverter that makes the power suitable for use in your home & sells any excess power produced by your solar array, (or wind generator or  water turbine), back to the electricity company.
 

If you are concerned at all about your power costs going up and would like to do something to reduce your monthly electricity bill, then a grid-tie solar system may be just the thing for you. 


These systems are easy to install and since they don't need batteries for back-up, (it is an option), the lack of batteries in these systems means no messy maintenance or replacements to worry about.  The solar modules can be mounted on your roof or out in the yard where they sit quietly generating power from the sun that you can either use directly or sell back to the power company.

If that sounds pretty interesting, you might want to look into what it would take to install a grid-tie PV system. 

The first thing you should do is contact your power company to see if they will allow you to connect a solar system to their electrical grid.  (Meridian sell back units for the retail price)
 

The next step is to figure out what size system will work best for you.

This is tricky because it all depends on how much energy you want the system to produce per day, what your power company rate is per KwH and of course how much money you want to spend on a system. 
The higher your utility rate is (¢ per KwH), the more economical a grid-tie PV system becomes since you are offsetting expensive energy that you would’ve bought from the utility company with clean free energy from the sun. 
Your site location is a big factor in determining how much energy any grid-tie PV system will produce.
