2. How Many Solar Panels to Get
2000 KWH per Month
• You can calculate the size of the solar
system and the number of necessary solar
panels using a not so complicated
algorithm. The numbers you have to put in
the equation are your monthly electricity
usage, the number of peak sun hours per
day, and the power of a solar panel.

3. Calculating the solar system size
for a 2000 kwh energy usage
• To exemplify, let’s start by assuming you need a solar
panel system that can generate 2000 kwh per month.
From the beginning, you should know that 2000 kwh per
month is a quite a lot of energy, and you would need an
impressive solar system to provide it. Although we use
this number just for the sake of the exemplification, in
case you do consume 2000 kwh per month, our advice
would be to take some energy reduction measures and
to remain connected to the electricity grid, just in case
the solar system cannot keep up with the demand.

4. • Now, you have to find out for how many hours per day your system
will be able to produce enough electricity for your needs. The panels
produce energy only when the sun is up in the sky, and it shines
directly on them. At night, the panels do not produce anything. In the
morning and in the evenings, when the sun is weak, the energy
production is also insufficient. Depending on the area where you
live, there might be 4-6 hours of peak sunlight every day, when the
system will produce the necessary electricity, and sometimes even
more than you need.

5. • If you want to have 2000 kwh per month, it means you have to produce
2000/30 kwh every day, that is 66.66 kwh per day. Considering there
are 4 hours of peak sun every day in your area, the solar system will
have to produce 66.66/4 = 16.66 kwh per hour, and that means 16660
in watts. Now, different types of panels produce more or less energy
watts. If you opt for one that produces 150 watts, then you will need
about 111 solar panels. Yes, that is a lot.
• To approximate the necessary space for such a solar system, you have
to know that, in order to generate 2000 kwh per month, you need a
system of 24.8 kwp (kilowatt peak). Every 1 kwp needs about 100 s.f.
of space.
• It is, indeed, a large system, but if you want to save some money on
bills, it is not necessary to build a system that provides all the energy
you use. You can remain connected to the electricity grid, and build a
system that supplies 30%, 40% or 50% of the energy you need,
depending on your budget and available roof space.
