What Size Solar System Do I Need Calculator

Solar panels for households typically come in the standard dimensions of 1 70m x 1 00m that s around 1 7m2 for every panel installed however the wattage output w of the panels will likely vary between 250w and 360w for a more efficient module.

What size solar system do i need calculator.

Then divide the kw output by your panel s efficiency to get the estimated number of solar panels you ll need for your system. This is a very general system size estimation. The number of solar panels of the size used in the calculation will theoretically meet that energy demand during a sunny day. For the most accurate and personalized off grid system size calculation call our solar experts at 1 800 472 1142.

To help you better estimate the potential size solar array your home will need the below chart can provide a little more clarity. One solar panel produces about 1 24 kwh per day. 2 4kwh is the battery size you will need you also use this as a rough guideline in this particular case i would increase the battery size by doubling because you need to take into account dod depth of discharge. To figure out how to size your solar system take your daily kwh energy requirement and divide it by your peak sun hours to get the kw output.

The follow image displays grid connected solar panel systems suitable for various household sizes. The average system size in the u s. Other factors such as peak load shade location available panel space and seasonal use need to be taken into account. We want to help you get the system that s right for you.

How big a solar power system you will need is largely determined by your usage. How many solar panels do you need for a 2000 sq. In order to calculate the below data we averaged annual kwh production in the top 12 solar states and assumed standard 250 watt panels in order to calculate how many panels you would need. Calculate the size of your solar system.

In the example above you would need 24 solar panels to account for 80 of your average consumption 29 6 kwh daily usage divided by 1 24 kwh per panel. It also shows an estimate of what each system will power. Solar shingles are smaller than panels and their wattage is lower as a result. A 5kw solar system may produce enough energy to power your home but you may not have enough roof space for a system of that size.

You can find out how many solar panels your home needs by using our solar calculator. Looking at the grid tied solar system calculator the first bit information you have to provide is your daily kw usage. You calculate how many solar panels you may need by dividing the maximum hourly solar energy system output by the wattage output of one single panel. However you can use the same procedure to estimate how many are needed.

The solar system size your home needs will depend on your electricity consumption and the climate of your region. Determine how many solar panels you ll need.
