Is my home right for PV?
A PV system needs unobstructed access to the sun's rays for most or all of the day throughout the year. PV panels are relatively unaffected by changing weather and the modules are angled to 'catch' the sun, not snow, so any snow that does collect melts quickly.

Here are some important tips that will help you determine if your home is right for PV:

PV systems are best installed on a southern exposed roof, however some east or west exposures may also be acceptable.

PV systems are ideally mounted parallel with the roof at a 35 degree roof pitch with no shading between the hours of 9 AM and 4 PM.

Shading can include trees, chimneys, TV antennas, satellite dishes, dormers & gables.

A PV system can be installed on any well-structured roof. If your roof is older and needs to be replaced in the near future, you may want to replace it at the same time your PV systems is installed.

The amount of space needed for a PV system is based on the output & type of the sys tem. Your roof size & orientation will determine how much PV you can install on your roof.

What is Net Metering?
Net metering occurs in instances that when a customer's PV system may generate more electric energy than their consumption. When this occurs, the electric meter will spin in reverse. The excess electricity is returned to the LIPA system. At the end of each month, the net metered customer is billed only for the net consumption, that is, the amount of electricity consumed, less the amount of electricity produced.

How much PV do I need?
As a starting point, you might consider how much of your present electricity needs you would like to meet with your PV system. For example, if you would like to meet 50% of your electricity needs with PV, you would work with a solar installer to examine past electric bills and determine the size of the PV system needed to achieve that goal. Remember, your roof size and orientation will also play an important role in the size of the PV system you can install.

What if the sun doesn't shine?
Your PV system will continue to produce electricity during cloudy weather, although the total amount will be reduced. Power will automatically be provided through LIPA at night or during inclement weather as needed.
