Solar Systems Design & Installation

Frequently Asked Questions


What are photovoltaics or solar panels?

Photovoltaics are semiconductor devices that convert light into electrical energy. The basic unit is a photovoltaic "cell" which is a large slice of semiconductor material. Usually, multiple cells are joined into a single self-contained unit called a "panel".  A solar panel is a weatherproof integrated package of solar cells ready for mounting.


How does a solar system work?

When sunlight shines into the solar panels it transforms the light into DC electricity. That DC electricity is then converted to AC electricity that is used throughout your home. During the day, if your system produces more electricity than is used in your home, the extra electricity produced is fed into the utility grid generating a credit on your electric bill. When this happens, you'll be able to see your utility meter actually spin backwards. At night, electricity is automatically drawn from the grid to provide your home with the power you need.


How do I know what system size I need?

The size of the system depends on a few factors. First is how much roof or ground space is available. Second, the amount of your electric bill and what you are trying to accomplish. Once these factors have been examined we perform a free site consultation to determine the most appropriate size system for your home.


How much does a solar system cost?

Cost for solar can vary; please contact us for an estimate.


What is the NJ Clean Energy Program?

The NJ clean energy program is a government-sponsored program that provides incentives for renewable technologies. Advanced Solar Products will handle all the necessary paperwork for your installation. For more information on the Clean Energy Program visit


What is the warranty of the systems?

The solar panels have a 25-year warranty from the manufacturer. We also warranty the inverters for 5-10 years depending on the manufacturer.


Why should I consider buying a PV system?

A PV system reduces or eliminates the amount of electricity you purchase from your utility provider. A PV system can save you money on your electricity bill and act as a hedge against future price increases. The electricity generated by your PV system is clean, renewable and reliable. You help your community by reducing the load on the utility grid and you can provide additional electricity for the grid when you generate more than you use during the day, when electricity demand is highest.
