Calculate Solar Panel Wttage Needed

Refer to your electricity bills for the past.

Calculate solar panel wttage needed.

The amount of energy your home uses. Divide the number of watts of power you use each day by the average hours of sunlight per day. Other factors such as shade location available panel space and seasonal use need to be taken into account. Continuing the example suppose that you get about three full hours of sun per day.

Southern facing roofs receive more sunlight in the northern hemisphere the average amount. 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. Go power retreat 100 watt rv solar kit 600 00. Calculate solar panel costs for your home 1.

A 100 watt solar panel produces approximately 6 amps per hour in direct summer sun without clouds. The average system size in the u s. To figure out what size solar panel batteries charge controller and inverter you need follow the simple steps below. Step 3 find the perfect solar panels for your rv.

This will be the number of watts you need to produce per hour. For the most accurate and personalized off grid system size calculation call our solar experts at 1 800 472 1142. Next you can estimate your average daily kwh usage by dividing your monthly usage by 30. Match your estimated weekly amp usage with the right rv solar panel kit.

You must simply divide the average daily kwh by the peak sun hours assuming a 30 day month an electricity generation of 1 000 kwh is equivalent to 33 33 kwh per day. 10 904 watts 3 hours 3 635 watts hour. Step 2 calculate your total weekly amps needed. 100 watt rv solar kits.

To really understand how many solar panels your solar energy system needs you need to determine. Is 5kw 5000 watts so you can use that as a benchmark if you re unclear on what your power needs will be. The first step is calculating the kilowatts needed. The power generation capacity of a solar panel is given in watts.

For example say your. Look at monthly kwh used on your electric bill the direction of your roof. Assuming we get 5 hours of direct sunlight we know a 100 watt solar panel will produce 30 amp hours per day. 100 watts x 10 hours 1 000 watt hours.

Once you know the peak sun hours estimating the number of solar panels needed for 1 000 kwh is simple. Calculate how much energy is needed. You probably consume more electricity during certain months of the year.
