Solar Grid-Tie, or Stand-Alone power supplies
|
Grid-Tie Solar Power Systems can be used for Net-Metering applications that export electricity from the Solar Array directly into the Grid, through your meter for credit against your bill.
Depending on your Load Requirments Solar PV panels can be arrayed and deployed on Ground Mounts, Roof Mounts, Side-of-Pole Mounts, and Top-of-Pole Mounts.
Sizing Solar PV arrays depends on the load requirements.
For example, if you need to generate 1,000 Kwh of DC energy with a Solar Array per Month, then DIVIDE 1,000 with the number of days per month (30.41), which in our example comes to 32.88 Kwh per Day.
Now, DIVIDE this daily Kwh load with the Daily Sun Peak Hours for your location from a Sun Chart. For Los Angeles, lets use 6 Sun Peak hours per day. This comes to 32.88/6 which equals 5.48 Kw.
This means that you need 5,480 watts of PV panels, in Los Angeles, to produce 1,000 Kwhs of DC electricity per month.
