Money saved on electricity through smaller or
eliminated electricity bills should be factored into your cost of solar
panels calculation. Have a look at your last few electricity bills and
calculate your expected energy reduction – factor the $30, $50, or $100
expected monthly saving into your solar cost analysis.
Freedom from the fluctuations of electricity prices
and from the international politics of fossil fuels is an enormous
future cost-benefit of solar energy. As fossil-fuel energy prices
continue to rise, solar power users will remain unaffected.
Carbon emission taxes are another factor affecting
the long term cost of solar power. As we struggle with the burgeoning
climate change crisis, countries are imposing their own per kg carbon
taxes and emissions trading schemes to curb pollution. These taxes will
increasingly make fossil fuel generated electricity more expensive, thus
make the comparative cost of solar cheaper.
