4. Multiply the input power by the energy tariff to calculate the hourly running cost. 2.4 x 35 = 84 cents per hour. 5. Multiply the hourly running cost by the number of hours per day you run the appliance to get a daily running cost. If the appliance is turned on 10 hours per day: 10 x 84 cents = 840 cents a day.

Jun 03, 2019· To calculate $/W, take the total out-of-pocket cost of the system that you are considering and divide it by the number of watts of capacity in the system. For example, a 5kW solar system has 5000 watts. If that system costs $15,000, then the cost per watt is ($15,000 / 5000W =) $3/W. When you’re comparing figures, make sure that you ...

All we have to do is find the current through the controller by using power = voltage x current. Take the power produced by the solar panels and divide by the voltage of the batteries. Example: A solar array is producing 1 kw and charging a battery bank of 24V. The controller size is then 1000/24 = 41.67 amps.

Apr 25, 2021· The image above shows how a 5.2-kW solar system starts at an estimated total cost of $14,820, which is then reduced by $3,853 because of the federal tax credit and $1,582 in electricity bill savings over the first year. The savings add up over 25 years, resulting in $46,712 total profit and an IRR of 19.91%.

Chris Barnes. To size your solar panel system you need to work out how much electricity you use and when you use it. A typical home uses 20kWh per day, which equates to a 5kW system. The number of panels is irrelevant, it's about the system's overall capacity. Panels are relatively cheap now and it makes sense to get as big a system as you can.
