You can input your Computer's details to calculate the exact usage and cost of your device. ThinkCentre desktops have received the EPEAT gold grade and are Energy Star 4.0 certified. / 1000. Enter the power in watts (W), time period in hours (h), then press the Calculate button to get the result in kilowatt-hours (kWh). The NRELs PV Watts calculator is a good way to ensure that your solar system can handle anything you throw at it. Check your inbox for your discount code. You also want a battery so you can power your devices in the evenings. The module refers to the type of panels your solar system uses. For example, 30 minutes would be .5 and 15 minutes would be .25. is a measure of energy that is equivalent to 1,000 watts of power for a 1-hour time period. There are plenty more electrical calculations you need to familiarise yourself with to keep your solar panel system running optimally. We'll assume we want to run this air conditioner for just 4 hours during the afternoon.
