To get the most out of your solar system you should first
check and see how efficient your home is? I am going to take you through a
check list for you to determine the efficiency of your home.
Let’s start with Insulation. It is very important to have
the right amount of insulation in your home because heating and cooling makes
up a very large part of the electric bill in most cases. The main areas that need to be insulated are
the attic, crawl spaces, and exterior walls.
The R value should be standard R-38.
If your R rating is lower you can add insulation to it to increase the
value. The higher the value the better
quality job the insulation will do for your home.
The next places to
insulate would be the windows and doors.
These areas need to have proper seals and no gaps or leaks. They can be sealed with calking and doors
have a number of different kinds of weather stripping and barriers that you can
buy. After you have checked your windows
and doors you may want to go around and check for any other wholes or cracks
that you notice drafts appearing.
Don’t forget to
check your water! You can wrap your
water heater in an insulation blanket as well as your hot water pipes in foam
insulation. Doing this will keep your
water warmer by 2 to 4 degrees. You may
also like to check your water heater to see if it is functioning properly. The heating elements may still work but start
to draw more power if not functioning properly so it is a good idea to get a
meter and test it once in a while to make sure its level of energy draw has not
changed and that it also is an energy efficient model.
Next up is light bulbs.
A standard bulb take 60-100 watts and a standard home can have anywhere
That’s a lot!
I suggest if you have a higher number of
bulbs to start with the most used light bulbs and replace them with LED
lights.
They give excellent lighting and
use on average about 5 watts per bulb.
Now that’s a huge difference.
from 20-50 bulbs.
Appliances are the final and most important energy hog. Your heating and cooling system can be for
most people number one in energy use.
You may like to go through your options here because there are
many. You may choose natural gas, wood
stove, pellet stove, rocket mass heaters, electric heaters, swamp coolers,
passive cooling, and air conditioning.
Each has there place depending on your needs.
The stove is a very
big item to look at. Using an electric
stove can range from 4000-7000 watts.
This option can be changed to a large counter top oven which takes
closer to 1300 watts per use giving you a substantial savings on energy. You may also opt for the gas stove.
For the Fridge and
washer/dryer make sure they are energy star rated to give you the best
efficiency possible.
Now take a look at the smaller things such as leaving the
lights and the t.v. on when no one is using them.
Maybe you can have a talk with the members of the house hold to help
remind one another to turn things off when no t in use.
After you have completed your energy audit on your home you
may find that your electric bill has gone down quite a bit already even without
solar. Now you can reap the rewards of
an energy efficient home and as you move on now to size your home for a solar
system you can feel confident that the numbers are right for your needs and you
are getting the best system.
