UO SRML: Solar position calculator - University of Oregon This calculator program returns solar zenith angle, declination, Julian day, equation of time, hour angle, instantaneous and daily extraterrestrial radiation values, and sunrise and sunset times. Calculation of extraterrestrial solar radiation (to horizontal surface at top of atmosphere) Latitude (decimal degrees, southern hemisphere is negative): Month: (January=1, February=2,.) Provides spectral solar radiation data for several U.S. sites for 1986-1988. 1 BTU = 251.9958 Calorie 1 BTU = 1055.056 Joule 1 BTU = 1055.056 Watt-sec 1 Langley = 1 Cal/cm 2 1 Calorie = 4.1868 Joule 1 Watt = 1 Joule/sec 1 Watt-sec = 1 Joule
Solar Angle Calculator | Solar Panel Angle Calculator The solar panels generate DC power, which is conserved in the battery for later use. The professionals at Excel Solar have been serving Brevard and East Central Florida since the early 80's. In that time, they have seen the solar industry evolve into this country's most affordable source for clean, reliable, everlasting energy. Calculations will use average annual hours - 1890 hrs/yr (5.25 hrs/day) % *This will affect your direct consumption of Solar Energy. (OR) Solar Panel Capacity you want to install. These easy to follow worksheets use the MS Excel application and allow you to perform a cost/payback/profit analysis of a proposed system, an energy audit, and/or calculations to help you decide on an array size, modules and an inverter, wire gauges, etc. With this information, we can determine your location's Global Horizontal Irradiation, also known as peak sun hours. Architect's View of the Sun spreadsheet This Excel spreadsheet provides solar geometry angles and radiation values. The solar map uses insolation, a measure of solar radiation energy received on a given surface area in a given time. YouTube. Figure 5. Use the solar energy calculator for an idea as to the benefits you may see from installing a solar photovoltaic (PV) system. Step 2. Figure 6 . download Excel spreadsheet with macro here. Load evaluation, also known as 'load calculation' or 'load analysis,' is an essential starting point of sizing any off-grid solar power system.
