The position of your house
The other factor that matters when it comes to determining how many
solar panels you will need is the position of your house. Because
the solar panels need to absorb as much sunlight as possible in
order to work effectively the more of a southern exposure your house
has the more power the solar panels will generate and the less of
them you will need. Make sure that the position the solar panels
need to go in has enough room to accommodate the number of panels
that you’ll need.
When you are figuring out where to put your solar panels try to
figure out where due south is in relation to your house and plan on
positioning the panels there. To find out where due south is when it
comes to your property you can take the number of hours between
sunrise and sunset and divide that number in half. The position the
sun is in at that time during the day is due south.
If your property doesn’t have a due south exposure or you can only
put the solar panels in an area that doesn’t get a lot of sunlight
you will need to either use an additional solar panel array on your
roof, or put in some solar roof shingles, or you can also use a
battery to help your solar panels produce more power.
When you make the decision to install solar panels it’s best to have
a trained solar panel consultant come to your property and look it
over. A solar panel consultant can advise you on the best position
for your solar panel array and can also help you determine exactly
how many solar panels you’ll need.
The amount of solar panels that you need to power your house will
also depend on the type of solar panel that you choose. Different
types of panels will give off different amounts of energy so if
you’re using your solar panels for full power in your home then you
should consider getting the highest grade monocrystalline solar
panels that are available because they have the highest electricity
return rate and are the easiest to custom fit because they are one
large sheet instead of groupings of individual PV cells.
If you are going to use solar power only as a supplement to
traditional grid power and to do things like heat your pool and hot
tub, or power your outdoor lights, then you can choose a less
expensive type of panel or you can buy fewer of the high grade solar
panels.
If you want to use solar power but aren’t sure that solar power is
going to be enough to power everything in your home then just
installing a few solar panels and using some solar energy is a good
way to find out how much solar energy your property can generate.
