How to calculate the number of
solar panel to be installed?
If you
have decided to opt for solar panel to fossil fuel, than let me congratulate
you for your decision of saving money and natural resources from depleting.
GOOD JOB! Now, that you have decided to go green by using solar panel the most
important thing to know is how many panels are required to meet the need of
your electrical consumption.
To determine the number of panels required we have to follow the steps given below:
1. Find the average daily
consumption of electricity: To find that you can take your
monthly bill and divide it by the number of days in the month.
2. Find the Peak Sun hours: For
this you can take help of websites that provide this information for you. The
websites provides maps and locations of the cities in your country. Upon
selecting the location where you are put up you get the peak sun hours of that
particular place.
3. Find the number of watts you
need per hour (W/H): To find this you just have to divide the no of watts of power
you use each day and divide it by the average hours of sunlight per day.
Let’s
take a simple example, if you need 500 watts each day and the peak sun hour is
5 hours than the watts per hour is 500/5
= 100 watts per hour.
4. Find the number of panels
required: Now that you know the consumption of electricity is 500 W/H following the above example, you can
select the panel you find best to suit your requirement. Panels have different
watt ratings for example 100 watts, 200 watts, 500 watts etc. So if you chose
500 watts panel you just need 1 panel and if you select 100 watts panel you
will have to go for 5 panels to meet your requirement.
5. Check the wattage of the solar
panel: “Volts
(measurement of voltage) x amps (measurement of current) = wattage (Product of
volts and amps)” For example,
if the panel is of 6volts and 5 amps then the wattage is 30.
And to
convert this wattage in to kilowatts you just divide the wattage by 1000…here
in this example the kilowatts is 30/1000=0.03
kilowatts.
