divider Q: How much power does a PV System store?
On Long Island where the utility electrical grid is readily available, the typical PV system uses the grid as it’s storage. For example if your system makes 100KWH more power than you need on a given day, it is sent to the utility grid as a deposit much the same as you deposit money in the bank. When you need it back (as in the night) you take it back at no effective cost, just like withdrawing money from your bank account. However, if back up power is a concern, battery banks can be designed and installed to work in conjunction with your PV system.
