Effect of Solar Angles on Incident Energy of the Flat Collectors
In this paper the daily, monthly, seasonally, and yearly optimum slope angles of solar collectors are determined for areas in Iran and new models are developed to calculate the monthly, seasonally, and yearly optimum slope angles for latitudes of to north. To achieve this purpose, the slope and surface azimuth angles of solar collectors for receiving maximum solar radiation were determined ...
متن کاملIncreasing arboreality with altitude: a novel biogeographic dimension.
Biodiversity is spatially organized by climatic gradients across elevation and latitude. But do other gradients exist that might drive biogeographic patterns? Here, we show that rainforest's vertical strata provide climatic gradients much steeper than those offered by elevation and latitude, and biodiversity of arboreal species is organized along this gradient. In Philippine and Singaporean rai...
متن کاملتعیین زاویۀ شیب بهینۀ ماهیانه، فصلی، ششماهه و سالانه کلکتورهای خورشیدی تخت در کاشان
The orientation of the flat solar collectors affects the amount of solar radiation received and absorbed by them. In this study, the optimum tilt angles of flat plat solar collectors in Kashan for the fixed monthly, seasonal, semi-yearly and yearly adjustments have been determined. If the solar calculations are based on the measured data, they produce more accurate results however in many parts...
متن کاملSolar Orientation Measurement Systems with Integrated Solar Cells
This paper presents a novel solar orientation measurement system based on solar cells. A methodology for calculating the solar orientation is developed in which the time and latitude angles of the sun are determined from the measured output voltages of inclined solar cells. Three types of measurement system are considered, namely a single cell type, a double cell type, and a quadrantal cell typ...
متن کاملVectorial algebra algorithms for calculating terrain parameters from DEMs and solar radiation modelling in mountainous terrain
Terrain parameters derived from digital elevation models (DEMs), such as slope gradient, aspect and cell surface area, are represented as a vector normal to the surface and calculated using the minimum areal unit of the DEM, that is enclosed between four data points. The position of the Sun is calculated by applying rotational matrices to a unit vector defined at noon as a function of latitude ...
