2. THE SOLAR ENERGY IS A RENEWABLE ENERGY
OBTAINED FROM THE SUNLIGHT AND
PRODUCED THROUGH SOLAR PANELS.
3. THERMAL ENERGY: IT CONVERTS SOLAR
ENERGY INTO HEAT BY MEANS OF SOLAR
PANELS AND COLLECTORS.
PHOTOVOLTAIC ENERGY: THE SUN LIGHT IT
CHANGES INTO ELECTRICITY THROUGH
PHOTOVOLTAIC MODULES.
4. THERMAL ENERGY
Thermal energy is often
accumulated from active
solar collector or more
often combined heat and
power plants, and
transferred to insulated
repositories for use later in
various applications, such
as space heating, domestic
or process water heating.
5. PHOTOVOLTAIC ENERGY
Solar photovoltaic power involves using
crystalline panels to convert energy from
the sun into electricity for use in your
home or business.
The basic unit is a solar cell made up of
thin layers of silicon.
When photons falling from the sun
interact with the silicon, electrical charges
are generated as direct current.
The panel photovoltaic modular is made
up of multiple photovoltaic cells and is
the principal building block of the
photovoltaic system.
The photovoltaics modules produce direct
current that is transformed to alternating
current by an inverter.
The inverter sends the AC to your home's
electrical panel, which supplies electricity
directly to your appliances, lights and
other electrical devices. If more electricity
is being produced than consumed, then
the excess is rerouted from your utility
meter into the utility grid where you are
credited for later use, a process known as
net metering.
6. PASSIVE SOLAR DESING
Passive solar design refers to the use of the sun’s
energy for the heating and cooling of living
spaces. The building itself or some element of
it takes advantage of natural energy
characteristics in materials and air created by
exposure to the sun. Passive systems are
simple, have few moving parts, and require
minimal maintenance and require no
mechanical systems.
7. DIRECT GAIN
Sun can enter through south
windows or skylights; open
plan can allow sun and stored
heat to serve entire top floor
of building. Large areas of
thermal mass surface should
be darker colored and free of
rugs, wall
hangings, etc. Light-colored
surfaces near glass reduce
glare. Outdoor view and
access to south are
encouraged.
8. INDIRECT SOLAR GAIN
The sun's heat is collected and trapped
in a narrow space between the window
and the thick masonry wall (thermal
mass or Trombe Wall) after it passes
through the windows. This heats the
air, which rises and spills into the room
through vents at the top of the wall.
Cooled air then moves to take its place
from vents at bottom of the wall. The
heated air circulates throughout the
room by convection. The thermal mass
continues to absorb and store heat to
radiate back into the room after the sun
has gone. Dampers can be placed in the
vents to prevent warm air from
escaping through them at night.
During the summer months, the process
is reversed. The thermal mass is
prevented from receiving direct sunlight
while absorbing the heat in the
room, helping to keep the temperature
cooler.
