Solar Hot Water Projects are the gateway into
a "Solar Age" of energy independence. Fossil fuels are no longer
necessary to keep the wheels of civilization turning. Build your own solar
heating system. Explore the Strawberry Fields Book Store
for more information. Alternative energies like
solar energy will increase in value as fossil fuel prices
escalate making energy efficient, solar
houses more valuable. Solar
collectors, solar hot water systems, heat storage vaults, photovoltaic
electricity, solar panels, and solar
greenhouses will soon become
the standard rather than the exception to the standard in the near future According to Buckminster
Fuller "We have wondered too far from the roots." An energy crisis can
only be avoided only if we learn to rely on a diffuse, sustainable resource like the sun. Become part of this green economy

Do-it-yourself solar thermal projects
can make us more energy independent. The greenhouse effect is a miracle
of nature that makes trapping heat possible. Without this method of
trapping heat our tiny planet would be a frozen waste land like the
Moon. A conscious effort to make better use of this miracle of nature can
free us from dependence on non renewable resources and allow us to at last live
in a sustainable economy unfettered by the restraints of big business and big
government. Thegreenhouse effect
is something that all domestic solar thermal systems have in common....
Solar collectors
also use the greenhouse effect
to capture
the sun's energy. Both solar collectors and solar greenhouses are able to harvest
the suns energy in the form of heat.
Two of these serpentine collectors cover a surface area 60 square feet.
The glazing is more durable than glass and much lighter.

to Build a Solar Hot Water System"
Solar Panels
are very much different than solar collectors. They use selective wavelengths of light to produce
electricity and they work best
in direct sunlight at a low temperature. Large PV systems are still quite costly.
They use inverters to
convert DC panel power to compatible AC power. This AC power is often interfaced
with the grid so that solar energy may be shared with others.
The
initial cost of a photovoltaic application will never be as low as the cost of
DIY solar heating projects that harvest the equivalent quantities of energy...
HOWEVER us civilized humans need more than heat alone to keep our computers
humming.
The cost of PV systems has come way down in the last 5 years. With the advent of thin film technology it appears
the price of PV will continue to plummet in the coming years, but the question
is can we afford to wait much. Every day that we wait is a day that we
miss out on a direct connection with the sun.
Heat and power are different animals and we need them both..
The AC/DC Differential
Controller responds to the difference in temperature between collector
and storage and turns an AC or DC pump on and off to maximize the heat harvest
from a solar hot water or solar heating system. Temperature monitors are
used to display the actual temperatures inside the collector and inside the heat
storage tank, but the controller will function without them.
This AC/DC
controller consumes
less than 1 watt of power per hour yet it is capable of regulating 300 Watt pumps.
It's a rugged, dependable, analog controller that may be mounted on a wall. The
temperature probes and power connections are attached to the terminals on the
bottom of the controller to facilitate wiring.

This house is based on a Harry E Thompson's Trickle Down solar thermal roof system but
it's been modified to for easy installation on top of an existing roof.
