Solar
energy technologies convert sunlight into electricity and can be used
to operate almost everything in your home. You can heat your water
supply and swimming pool with a solar water heater. Solar panels turn
the sun's energy into DC current. An inverter then changes DC current
to AC current so that it can power electric appliances in your house
such as televisions, computers, lamps, refrigerators, etc.
Using solar energy technology in the home requires a significant
upfront investment. One solar panel provides approximately 50 to 200
watts of power per day and can cost anywhere from $300 – $600.
Therefore, using a home solar panel system to power all of your appliances
may not be the most cost-effective solution.
Still, you should be able to reduce your home electricity costs each
month by using solar panels. It could take many years for you to make
back your initial investment, but using solar energy provides other
rewards. Just as the first adopters of hybrid car technology invested
to reduce their carbon imprint, you too will have the benefit of feeling
positive about your green lifestyle. By using solar power you will
eliminate 120 tons of carbon dioxide over a period of 30-plus years.
(This assumes you use a 6 kW system for the duration of its expected
lifespan.)
To get an estimate of how much money you will need to spend on solar
panels for supplemental power to your home you should perform an energy
audit of your house. This requires assessing how much power your solar
powered system will need to generate each day. Grab a pen and paper
and write down the wattage of all the electrical items you run in
your house each day (e.g. computers, light bulbs, refrigerator/freezer,
televisions, etc.). Then, add all the numbers up. Not only will this
give you an idea of how many solar panels you will need, but it will
also make you aware of how much energy you use in a given day in your
household. You may find yourself reducing your electric bill just
by doing this audit and eliminating any excess use of appliances.
After you've created a list of appliances you'd like to operate by
using solar power, calculate the amount of wattage you would use during
one day. Then you can calculate how many solar panels and estimate
the cost of the solar power system you will want to install. If you
need help with this process, then you should contact a sales representative
at a solar panel store.
While investing in a solar power system can cost thousands of dollars,
the result of not using solar power is greater pollution and consumption
of our most valuable natural resources. For those interested in sustainable
living and a green lifestyle, the benefits will likely outweigh the
upfront costs. In addition, there are other economic benefits to installing
solar panels. Advocates for solar power point out that there are state
and federal financial incentives to encourage solar energy use. Finally,
advocates for solar energy also point to a 1998 study by ICF Consulting
that suggested that for every one dollar less spent on annual energy
costs a home's value increased by approximately $20.
