In addition to data accuracy, the ability of ERA5 to characterize the stability of solar energy is another important aspect. We further calculate the foregoing metrics (i.e., P50, P90, CV and LOLP) using the time series from 11 BSRN stations with continuous observations and compare them with the results based on ERA5 estimates (Fig. …
MODERN SAILBOAT DESIGN: Quantifying Stability
To find its CSV, first calculate DCF–12,000 ÷ 64 = 187.5–then find the cube root of that result: ³√187.5 = 5.72; note that if your calculator cannot do cube roots, you can instead take 187.5 to the 1/3 power and get the same result.
