"); This step-by-step Solar Power Calculator offers a guideline for typical appliance ratings and sizing of solar systems. Featured projects. Calculation of extraterrestrial solar radiation (to horizontal surface at top of atmosphere) Output can be watts per square meter (W/m2) or equivalent evaporated water depth (mm/d) Latitude (decimal degrees, southern hemisphere is negative): 1 Calorie = 4.1868 Joule They are available in Microsoft Excel and Open Office format. The project will yield a yearly production of 6,034 kWh (DC), with higher production in the summer months due to the increased solar radiation It calculates typical performance of solar electric arrays for more than 200 locations in the National Solar Radiation Database, given the system peak output and orientation. This tool gives estimates based on information you provide, and a number of assumptions to indicate potential benefits. I have included some sample numbers simply fill in the areas with green shading and let the orange ones do the calculation. The key results can be found on the first tab 'Results'. Try to account for everything, keeping in mind that off-grid homes should use efficient appliances, and the major heating loads (water & air heating) are usually not electric. dom_i.query(this).attr("title",imgAlt); Start by adding all of your household items to the list below Add each type of item individually and specify the amount of items and the amount of time the item is switched on for during the day. } if(imgMarginLeft.indexOf("px") > 0){ dom_i.query('img','.centerColImg').each(function(){ OPEN or DOWNLOAD the Excel spreadsheet. PVCalc allows you to calculate the ROI of PV solar energy projects - viewed as financial investments. if(imgMarginTop.indexOf("px") > 0){ User notes and assumptions. I decided to check how complicated it is to calculate solar radiation for your location. E = Energy (kWh) A = Total solar panel Area (m2) r = solar panel yield or efficiency (%) H = Annual average solar radiation on tilted panels (shadings not included) 1 Langley = 41868 Joules/m2             (see Conversion Sequence 2, below) However Weather Underground can accept more data to analyze weather statistics. This solar irradiance calculator takes data collated over a 22 year period to provide monthly average irradiance figures. Solar power calculator. First off, input your system size in the project details section of the inputs tab. We strongly recommend contacting a certified installer to obtain an accurate quote and calculation for your planned solar PV system. Solar Energy. Here are a few steps to use the solar ROI and payback calculator in Excel. Solar Radiation Calculation Dr. Mohamad Kharseh E-mail: kharseh@qu.edu.qa mohkh3@Hotmail.com . This user manual and accompanying Microsoft Excel spreadsheet http://aces.nmsu.edu/pubs/_circulars/CR674/CR674.xlsm are intended to be used as a guide for calculating solar time, angles, and irradiation, and to aid in feasibility and implementation decisions for solar energy projects. 1 Watt = 1 Joule/sec Use the solar energy calculator for an idea as to the benefits you may see from installing a solar photovoltaic (PV) system. Get notified about subscriber only specials, stay up to date on legislation changes, plus find out about newer, smarter and more energy efficient products. The calculator is very easy to use and is fully comprehensive enough to adjust your assumptions to find the most optimal solution. Calculate Revenue })*/ It also displays the local time at which solar noon occurs. Welcome to the solar spectrum calculator. The energy emitted by the sun is called solar energy or solar radiation. The results are presented graphically, divided into four sub-categories. }else{ After entering the installation data press 'Calculate'. I can/will add an old Excel spreadsheet calculation that I did in the past to my projects. C t. Γ. What to keep in mind when using the calculator: Total sun power daily: On an average day your total PV sun power generated is about 5.5 hours (South African conditions) Hence a 3kw 230v system should generate 16Kwh per day. /*dom.query(document).ready(function(){ For our example (London) the annual horizontal global solar radiation is 2.79*365=1018 kWh/m2 per year. I have included a simple excel calculator to help you size up your system. Our Solar Calculators Our Solar Calculators . Solar insolation is a measure of solar irradiance over of period of time - typically over the period of a single day. These values are used when modeling solar radiation. Welcome to the solar spectrum calculator. imgMarginTop = imgMarginTop.replace("px",""); Please note that calculations in the spreadsheets are only valid for dates between 1901 and 2099, due to an approximation used in the Julian Day calculation. Calculators that use kilowatt hours are more accurate because they consider your exact energy needs Determine your usage with our Energy Calculator. System Size 51 MW know more; 10.8 MW Rooftop Solar Power System – ANERT, Kerala. } 1 Watt-sec = 1 Joule 1394.00 WPA No. dom.query(this).attr("title",title); ENGINEERING FOR RURAL DEVELOPMENTJelgava, 28.-29.05.2009. NREL's PVWatts ® Calculator Estimates the energy production and cost of energy of grid-connected photovoltaic (PV) energy systems throughout the world. A Simple Energy Calculation Method for Solar Industrial Process Heat Steam Systems Randy Gee January 1983 To be presented at the ASME 6th Annual Solar Energy Division Conference Orlando, Florida 19-21 April1983 Prepared Under Task No. } The following spreadsheets can be used to calculate solar data for a day or a year at a specified site. } Whilst our comprehensive solar power calculator is the main starting point for people looking into solar, we also provide calculators for: battery storage, off grid systems, electricity usage, system size, solar financing, rebates and feed in tariffs. if(imgMarginBottom.indexOf("px") > 0){ 1 BTU = 1055.056 Watt-sec if(imgAlt != 'Broken Link' && imgAlt != '' && imgAlt != 'offsite link image'){ 1 Watt = 3.41216 BTU/hour                     (see Conversion Sequence 5, below) Solar Calculator is an application that calculates the 24 hour energy requirement of a household and based upon that calculates the number of Solar Panels and Batteries required by the Solar System. This step-by-step Solar Power Calculator offers a guideline for typical appliance ratings and sizing of solar systems. Appliance. Recognized as one of the premium Tier-1 bankable solar panel and module manufacturers internationally, Tata Power Solar supplied 51 MW ground mount solar power systems. Solar Calculator. Using the entered values, the spreadsheet will calculate solar time, angles, and irradiation (i.e., sunlight intensity) in the corresponding sheets. The simple payback calculation carried out in the calculator considers all costs as an initial investment outlay, a figure for which is entered by the user under question 5. var imgTitle = dom_i.query(this).attr("title") == undefined ?
