|| The most important inputs to the design of an off-grid system are the anticipated load and the availability of the input energy source such as the solar radiation or wind speed. Improperly accounting for either can result in systems that are too large–in which case resources are wasted–or too small, in which case the system is unreliable. This webinar discusses ways to estimate and characterize the load and energy resource availability of off-grid systems. Our discussion will be guided by measured data from real-world mini-grids. Practical approaches to assessing the viability of solar, wind, hydro and biomass sources will be covered.
