"Solar Power Versus Generator – The
Choice:"
As I write this in early 2007, the controversy over
global warming has heated up (pun intended), and
people are taking another look at solar power versus
generator. For those living outside the power grid,
the second look may save not only the green in the
rain forest, but also the green in the bank.
Many who live "off the grid" in isolated
locations have traditionally relied on generators for
electrical power. Others have installed generators for
back-up, emergency electrical power. Neither thought
there was a choice, but now there is a choice: solar
power versus generator.
In this article, we look at the choice. Which is more
economical; more convenient; more environmentally
friendly? Should you make the change?
Solar Power versus Generator - Cost
The cost of solar power versus generator is much less
over the long term.
The initial cost of a solar power system will be
greater than that of a generator system. This is often
the reason people install a generator rather than
choose solar power. One must look beyond the initial
cost, however, to get the full comparison of solar
power versus generator.
* Solar power, once installed, has little maintenance
or further expense. There is no fuel to purchase,
since the sun's energy fuels the system.
* Generators are not so. After installation, a
generator will require regular servicing by a
professional every 6 months. Generators require fuel
– a cost that is constantly increasing. Moving
generator parts must be replaced from time to time due
to wear and tear.
Solar Power versus Generator – Convenience
Convenience is another factor to consider when looking
at solar power versus generator power. Solar power is
much more convenient than generator power.
* Solar power may be less convenient to purchase and
install, since it is not as widely available as
generators. This is due to the currently small market
for solar power. As the market increases, however,
this will be less of a problem. Solar power systems
have no moving parts to wear out or need lubrication.
Once installed, solar power requires little attention.
The user can almost forget it.
* Generators are widely available, so convenient to
purchase and install. Convenience decreases after
installation, though. A generator must be monitored
frequently to be sure sufficient fuel is available. It
must be refilled often when used as a regular source
of power. Fuel must be ordered and delivery taken –
or fuel must be hauled by the owner. The system must
be serviced twice a year. This servicing will include
filter changes, an oil change, a tune up, and complete
inspection of the entire unit. Worn parts must be
replaced.
Solar Power versus Generator – Efficiency
The solar power versus generator battle includes the
matter of efficiency, too. Which is more
cost-effective? The facts seem to point to solar
power.
* Solar power is received in through the panels, free
of cost, and stored in batteries. It is ready for use
when needed, but in times of reduced usage, the power
remains in storage.
* Generators run constantly, regardless of the amount
of power being used at a given time. As they run, they
consume costly fuel. When power usage is reduced in
bright daylight, generators must continue to run.
Solar Power versus Generator – Dependability
Some argue that, in comparing solar power versus
generator, we must compare the dependability factor.
In this area, they claim, generators win.
* Solar power is very dependable in locations that
have bright sunlight 300+ days of the year. In areas
with less sunlight, or during periods of cloudiness
and storm, solar power is less dependable. The system
will continue to provide power from charged batteries,
but will eventually go dead. Having said that, it must
be noted that Germany, which has far fewer sunny days
than most of North America, is said to have much
higher usage of solar power. The problem of
dependability seems not that big.
* Generator systems do not depend on sunlight. They
do, however, depend on fuel. If storms or some other
disaster hinders one from replenishing the fuel
supply, generators also become useless.
Solar Power versus Generator – Eco-friendliness
Finally, eco-friendliness must be considered in any
discussion of solar power versus generator. That is,
which is kinder to the environment: solar power or
generator? The obvious answer again is solar power.
* Solar power has no emissions when working. There is
no pollution involved in fuel production – no
greenhouse gases. It is totally clean. Solar power
uses a renewable energy source.
* A big drawback to generator use is still the matter
of emissions and the environment. Generators are
usually run on diesel fuel, and diesel fuel is
produced from a fossil fuel. There are emissions in
the production of the fuel, and also in its use.
Diesel generators are a major source of air pollution
and high sulfur levels in North America. Exposure to
diesel generator exhaust can lead to health hazards.
Solar Power versus Generator – the Solution
For most people, the resolution of the solar power
versus generator debate is to install a hybrid system.
Using solar power as the main energy source will save
money. The fuel is free. Solar power is convenient,
efficient, and eco-friendly. What it lacks in
dependability can be made up by having a small back-up
generator for prolonged cloudy periods.
My Choice
When I compare solar power versus generator, I
definitely have to choose solar power. It is clean,
free, quiet, and peaceful.
