In the past few months, I've personally noticed a spike in interest
regarding solar energy production. I don't know if it's due to
storm related roof work, or just a general shift in attitudes,
but the interest is certainly welcome. Whether you're presently
contemplating an installation, or interested in going solar "down
the road", it pays to understand some basics.
The basic technology of
photovoltaic cells used to convert
sunlight to energy is truly "nothing
new under the sun". The first pv cell
was actually created in the 1880's!
Over time, cells have become
increasingly efficient, cheaper, and
easier to produce. Current research
in "thin film" technologies proposes that pv cells may someday
be incorporated directly into building components like roofing
shingles and siding. For the time being though, panels are the
principal medium employed for solar installations. Panels may
differ in terms of price, efficiency, and reliability, so research is
warranted before choosing one for your home.
Site considerations, such as orientation and shading, play a
significant part in determining the efficiency and feasibility of your proposed solar installation. Solar professionals use
specialized tools and GPS technology to analyze these features.
If your site is a good candidate,

you should also give some
thought to your roof (assuming a rooftop assembly). If your 15
year asphalt shingled roof is 12 years old, you should probably
have it replaced before the panels to avoid costly remove and
replace expenses when the roof does inevitably require repair.
Most quality panels are warrantied for 20 years or more, so
make sure your underlying roof is good for the same.
A residential solar installation can be a significant investment,
but there exists several options for financing. Installation costs
are often offset in part with government rebates and "energy
credits" which can be sold back to utility companies. Some
companies also offer minimal or zero down payment options. In
this case, the installing company owns the panels, and gives you a
preferential rate for your electric usage. Either option can benefit
you, the homeowner, by lowering your utility bills and providing
the peace of mind that comes from clean energy production.
