Residential Solar Energy Systems
|
 Solar
electricity, solar hot water, and radiant heating systems
are all ideal energy alternatives for your home.
Sun Light and Power designs and installs all three types
of systems, both in new construction and in existing structures,
throughout the San Francisco Bay Area.
Solar Electricity (Photovoltaics)
Generating Electricity with the Sun
The same technology that provides electrical power to satellites
and space vehicles can produce most or all of the power
your household typically needs.
A solar electric system sends any excess power produced
during the day back through the electric meter and into the
utility power grid. This causes your electric meter to run
backwards and you are credited for this electricity. When
you are using more power than you are producing, the meter
runs forward as you use up your credited energy. With back-up
batteries, your solar electric generator can both furnish
power for your use during the day as well as provide for
your nighttime electrical needs without depending on the
grid.
 Benefits of a Photovoltaic System
Owning a solar electric
system is now truly affordable and cost effective thanks
to recent improvements in solar cell
production efficiencies, California state rebates, state
and federal tax credits, as well as provisions in the so-called "net
metering" laws.

Solar Thermal Systems
Heating Water with the Sun
If you're taking
positive steps toward reducing your utility bills, installing
a solar water heating system may be a good
cost-saving option for you. A solar
thermal system will greatly reduce the portion of your utility costs that relate
to water heating – gas or electric -- while offering an opportunity for
sensible green investment.
Most basic systems consist of: (1) “collectors” which
heat the water and are installed on a rooftop (but can be
located on the ground), and
(2) a hot water heater, which is to be used as a storage tank and for back-up
heat during the cold months of the year. (A full-size system will typically
provide most of a home’s hot water between March and October.)
Solar Thermal
Makes Sense
In recent years, Solar Thermal systems have not received
the media attention of other renewable products such as photovoltaics
or wind power, but this
low-tech alternative is tried and true. For detailed Benefits and Features
