The conventional sunrise and sunset values are influenced by an adjustment factor, which takes into consideration atmospheric refraction as well as other atmospheric conditions that make the sun appear to rise sooner and set later. There is only one input in the Excel calculator. You will essentially make payments as a lease instead of your current power prices. Sinetech advises that the user first look at all the appliance rating plates they wish to run on solar power (which is usually fixed at the rear or bottom panel of the appliance) or at the manual to obtain the correct Watt rating. In order to determine your return on investment and payback, you need to know what you are paying up front to install a project. A typical rate of savings is 10-20% off of your current energy bill. That means that the appliance is using 575 Watters per hour (1kW = 1000W). Enter your city or address in the search bar and click Go. For this example, lets say you live in Denver, CO. 2. What has benefited consumers the most is that solar energy remains competitive with any asset class out there. A cells menu can be accessed by placing the cursor on the cell and clicking on it. Single PhaseThree PhaseNot Sure, Are you looking for backup power only or backup power with solar? The 2-AXIS TRACKER option is not affected by either the azimuth or tilt angles because this system always points the panels directly to the sun in both azimuth and elevation. Now that the location and calculated angles of the sun at a given time of day have been determined, the position of the sun at any time of day as well as its intensity can be predicted.
