Step 3 for solar panel installation: solar panels
Posted by Cecilia under: Energy; Home .
After step 1, insolation and step 2, inverters our third and last step for installation of solar panels is the most obvious part: determining how many solar panels you need.
How can you find out how many solar panels you’ll need?
To determine the amount of solar power generation you require, multiply your average daily electrical demand in kWh by 1.2. This means that the solar panels should exceed the basic power requirements by 20%.
As an example: if your home needs a total of 800 watts per day, divide 800 by the daily average of 6 hours of sun per day and you come up with roughly134 watts per hour. Following the 120% rule above means 134 watts x 1.2 = 160 watts. In this case you have to look for one 160watt solar panel or two 80watt solar panels.
Once you know the size of the required solar panels you can choose among the different types such as monocrystalline, multicrystalline or amorphous silicon solar cells. Important considerations for the type of solar cells is the available roof area and other factors such as insolation and shadowing.
