Solar Technology Works
There are two types of Solar Systems to
consider: Solar Electric/ Photovoltaic (PV) Systems and
Solar Thermal Solutions are both available to residential
and commercial users.
Photovoltaic (PV) Power Systems:
PV systems create electricity that can be used in your
home or business to run your appliances, lighting, and
central air conditioning just as the power you would use
from your utility’s electric grid. There are three
distinct ways to hook up PV systems: direct grid-tie,
grid-tie with back-up, and stand alone. Mercury Solar
Systems specializes in direct grid-tied systems. Only
Grid connected PV systems currently has state and federal
Solutions: Solar Thermal
is used to heat water in your home or business and can
help reduce the costs of heating. Many people are interested
in this technology when they have water based heating
services or if they have a pool to heat in the cooler
climates. Incentives are currently not available from
the state or federal government for Solar Thermal Systems.
How Does Solar Electric Work?

Simply stated, Solar Electric or Photovoltaic
technology converts sunlight directly into electricity.
Sunlight hits the solar electric array installed on a rooftop
(ground or pole mount options available), which generates
direct current (DC). The inverter changes the direct current
into alternating current (AC), which is used to meet your
electricity requirements. When your usage exceeds the generation
capacity of your PV power system, your utility company provides
electricity as usual. However, for 10 kW or less residential
systems in New York State, on days when your solar generation
exceeds your usage, you can actually see your electric meter
spin backwards as you gain credit from your utility company
for the excess power that you produce.
