With the Oregon solar feed in tariff, Energy Trust incentives, Federal
tax credit, and Oregon state
tax credit, there has never been a
better time to invest in a solar electric system in Oregon. In most cases
the net system cost of a Residential solar electric system after incentives
is $0.00.
Photovoltaic (PV) systems convert sunlight directly into energy and are quiet,
safe, and reliable. Buildings with PV systems remain connected to a utility grid or to another alternative energy source for times when the facility
requires more energy than the system can produce (i.e. at night). This
eliminates the need for batteries in most grid tied systems.
Most PV systems come with up to a 25 year manufacturers warranty and will last
more than forty years with proper care. Each system varies in size and can be made according to the specifications of the customer. The user can monitor
the energy produced by these systems by a graphical interface either online or inside the building.
Residential PV systems typically range in cost from $5.00 - $6.00 per watt
installed. These costs vary depending on the type of system, how and where
the system is mounted, the amount of utility power that needs to be offset,
and other variables. Solar systems cut the average electric bill between 20%
and 100%. When the system produces an excess of power it is possible to sell
this power back to the utility company for the same rate that company
charges. This is called net metering.
Solar panels are made up of photovoltaic (PV) cells,
which convert sunlight into DC (direct current) power. The DC current from
the solar panels goes through an inverter, where it is converted into AC
(alternating current) power. AC power travels from the inverter to the
electrical panel to power your building. With your business connected to the
utility grid, all electricity flows automatically. When your system is
producing more energy than you are using, it is fed back into the grid. The
energy that you feed back to the grid is then credited to your utility
account at a rate or 1 to1.
There are many reasons that Solar Electricity is a good idea. Lets
look at solar as an investment:
Typically a solar electric system will provide a seven to fifteen percent
return on investment per year. Also, when a solar system generates savings
for a homeowner its yield is not taxable.
If you want to find a ten percent yearly after tax yield on an investment
that is as safe as solar, you would probably fail in today’s economy.
In fact, it is now possible to borrow at five to six percent to make an
investment in solar that yields more than ten. As part of a home improvement
loan the interest is deductible so the real cost is even less.
However, there is a big difference between going solar to avoid high
utility expenses and placing the same money into a stock, bond or CD. While
the traditional avenues of investment are available to us as options, we
really have no choice about our utility bills. Unless we choose to live in
cold, dark homes, we must keep paying that monthly energy charge. So the
choice to go solar is really more about how you are going to spend your
money rather than whether or not the payback is less than five years. It is
similar to the rationale behind making a home purchase rather than renting
one. Home ownership is all about developing equity and retaining value while
renting is just a permanent never-ending expense. When you own a solar
energy system, you are no longer renting energy from the utility; you are
generating energy yourself and developing equity by putting your savings to
use elsewhere.
