Meteonorm dataset limitations
The key limitations of Meteonorm's representativeness lie within the use of 1) interpolated and 2) synthetic data. Interpolations rely heavily on surface observation data, which are not equally distributed. Synthetic estimates are useful when high quality direct observational data does not exist. However, given the presence of a global fleet of high resolution weather satellites that directly image cloud cover - this is not the case.

Let Solcast take the pain out of PV generation forecasting at your solar farm asset
Owners and operators of solar farms already have one too many things to think about. Compliance items stack up by the thousands very quickly. Utilities providing their network connections can impose new requirements without warning. Manufacturers of key components can go bankrupt and leave you without an important spare part! Don't let setting up solar forecasting technology at your asset be another pain-point. Use the Solcast API Toolkit!

Lowering uncertainty is fundamental to managing solar investment risk
The principal input to the rate of return calculation for a solar farm asset is the expected revenue generation from the solar farm. This highlights the importance of high quality solar irradiance data: revenue generation is primarily influenced by the availability of solar irradiance at that location over time.

Solar Power Forecasting: what it is and how to do it
Solar power forecasting is at its core a weather forecasting problem. It starts with modeling of the Sun's position with respect to a given location at the Earth's surface, before then modeling the transmittance of solar radiation through the Earth's atmosphere.

Behind the meter solar power forecasting and PV fleet visibility
As soon as penetrations of behind the meter solar PV sites reach 1-2% of total load, forecasting the power output of these PV systems starts to become critical for efficient market and network operation. Without including a behind the meter solar forecast into the overall load forecasting operations, errors in the daily load forecast start to appear. Thankfully, Solcast's Grid Aggregations are easy to set-up, are highly accurate, and can help solve this challenging problem!
