Let
DRB Construction
determine what solar power can do for you. A solar
electric system uses the power of the sun to supply you
with clean energy, saving or eliminating expensive
utility bills.
For new construction solar energy will more that pay for
itself during the first few years of ownership. For
existing homes or businesses, you will be able to lower
your monthly electric bills while increasing the value
of your home!
Take advantage of rebates, tax credits and get a buyback
from your electric company for excess electricity that
your solar panels produce. For information about
programs in your area, go to
http://www.dsireusa.org. DSIRE is a
comprehensive source of information on state, local,
utility, and federal incentives that promote renewable
energy and energy efficiency.
DRB Construction
will evaluate your situation and offer solutions which
will assist you in the efficient and economical
operation of your home or business.
Solar technologies. Many technologies have been
developed to make use of solar radiation. Some of these
technologies make direct use of the solar energy to
provide light and heat, while others produce
electricity.
Photovoltaics. The solar panels (photovoltaic arrays)
have direct sunlight Solar cells, also referred to as
photovoltaic cells, that use the photovoltaic effect of
semiconductors to generate electricity directly from
sunlight. Until recently, their use has been limited
because of high manufacturing costs. One cost effective
use has been in very low-power devices such as
calculators with LCDs. Another use has been in remote
applications such as roadside emergency telephones,
remote sensing, cathodic protection of pipe lines, and
limited "off grid" home power applications. A third use
has been in powering orbiting satellites and spacecraft.
Solar Thermal systems can supplement Solar Electric
systems. These systems will heat water which is directed
to your boiler, hot water heater or separate storage
tank. Several variations make for an enormous cost
saving investment. Although there is maintenance
involved, thermal is a high quality way to reduce
reliance from fossil fuels. Presently, solar thermal is
primarily used for commercial, industrial or large
residential buildings with high usage.
Solar heating systems. Solar hot water systems use
sunlight to heat water. They may be used to heat
domestic hot water or for space heating. These systems
are basically composed of solar thermal collectors and a
storage tank. The three basic classifications of solar
water heaters are:
1. Active systems which use pumps to circulate water or
a heat transfer fluid.
2. Passive systems which circulate water or a heat
transfer fluid by natural circulation. These are also
called thermosiphon systems.
3. Batch systems using a tank directly heated by
sunlight.
Solar lighting or daylighting is the use of natural
light to provide illumination. Daylighting offsets
energy use in electric lighting systems and reduces the
cooling load on HVAC systems (this assumes that
daylighting is replacing incandescent lighting, which
produces more heat than light). The use of natural light
also offers physiological and psychological benefits,
although this is difficult to quantify.
Daylighting features include building orientation,
window orientation, exterior shading, sawtooth roofs,
clerestory windows, light shelves, skylights and light
tubes. These features may be incorporated in existing
structures but are most effective when integrated in a
solar design package which accounts for factors such as
glare, heat gain, heat loss and time-of-use.
Achitectural trends increasingly recognize daylighting
as a cornerstone of sustainable design.
