![]() ![]() ![]() The current version of the code is restricted to the analysis of reflector systems which have flat rectangular or circular targets. CIRCE may be used to analyze reflectors that are spherical, parabolic, or flat in shape and are either continuous surfaces or faceted. In CIRCE, the concentrator errors are convolved with the solar intensity profile (sunshape) to produce the flux-density distribution more » on a specified target plane. CIRCE was developed with the objective of providing knowledgeable users with an easily used design tool which does not require a large investment of time to obtain results. CIRCE, an acronym for Convolution of Incident Radiation with Concentrator Errors, was developed from HELIOS, a large multipurpose cone optics computer code for the analysis of central solar receiver systems. ![]() In this paper a computer simulation code called CIRCE is discussed and examples of its application to several point-focus concentrating collector geometeries are presented. Some of the modeling in HELIOS and samples of results are described. Several output choices are available, including graphical display of flux density distributions, of shadowing and blocking and of sunshape. Nondeterministic factors such as sun-tracking errors and facet-surface errors are described statistically and combined with the sunshape by numerical convolution. Measured angular-distributions of incoming photons (sunshapes) and effects of aureole scattering are incorporated. more » Atmospheric attenuation effects are included. HELIOS calculates the ''sun position'' and uses it to establish alignment geometries. ![]() Comparisons of HELIOS results with measurements have given good agreement. HELIOS has been used extensively to analyze questions on safety, performance, design trade-offs, and tower protection engineering. The problem has individual subroutines for each task in order to incorporate options for a variety of facet shapes, heliostat designs, field layouts, and tower-receiver apertures, and to facilitate additions and code improvements. The HELIOS computer code calculates the power concentrated by a field of individually guided heliostats and the resulting flux density (watts/cm/sup 2/) falling upon an arbitrary target grid. We develop sustainable solutions in harnessing the power of the sun that impacts on the surrounding eco-system for a cleaner and greener future.= , Consuming renewable energy consumption at affordable costs minimise carbon emission and protects ‘green’ environments. Certain countries can be flexible in using solar energy for locations and government incentives. It estimated that renewable energy generation increased by about 1% in 2020.Īs an energy alternative, it helps to reduce dependence on fossil fuels and contribute to environmental advantages. This is because solar power has emerged as one of the most rapidly growing renewable sources of energy. International Energy Agency (IEA) reported that renewable energy generation increased by almost 3% in 2019. To pursue our long-term climate goals, we need to use renewable energy to reduce carbon emissions. The increased use of fossil fuels contributes to global carbon emission build-up. 60% of total global greenhouse gas emissions contribute to climate change. The United Nations Development Programme (UNDP) stated that, since 1990, global emissions of CO2 have increased by more than 46%. ![]()
