Can I heat my house with
photovoltaics? Using electricity to heat a house, as anyone who
uses electric heat and pays monthly bills to the utility knows, is very
inefficient and costly. Theoretically, one could heat one's home with
photovoltaics (electricity is electricity, whether it comes from PV panels or
from a coal burning power plant). Practically, though, this would be costly, as
producing electricity from a PV system is more expensive than purchasing it from
the utility. One can, however, heat one's house very effectively and cheaply by
harnessing the sun's energy in other ways.
5. What are the components of a PV system?
Photovoltaic Cell -- Thin squares, discs, or films of semiconductor material
that generate voltage and current when exposed to sunlight.
Module -- Photovoltaic cells wired together and laminated between a clear
superstrate (glazing) and encapsulating substrate.
Array -- One or more modules with mounting hardware and wired together at a
specific voltage.
Charge Controller -- Power conditioning equipment to regulate battery
voltage.
Battery Storage -- A medium that stores direct current (DC) electrical
energy.
Inverter -- An electrical device that changes direct current to alternating
current (AC) to operate loads that require alternating current.
DC Loads -- Appliances, motors and equipment powered by direct current.
AC Loads -- Appliances, motors and equipment powered by alternating
current.
