TMY variants - there's no universal right choice. This guide explains what they are, why selection introduces uncertainty, and how non-specialists can transition to time series data for more reliable yield estimates.

Solcast has introduced new parameters for PM2.5 and PM10 particulate matter concentrations in its API to improve the accuracy of photovoltaic (PV) soiling loss modelling globally. This integration supports data-driven soiling analysis by combining particulate data with irradiance and weather information for better energy yield predictions.

Ecoflow supports its home solar and storage customers, through an app that helps homeowners understand their energy use and how they use their own solar power. To support this, the EcoFlow product team have integrated high-quality, global solar forecasts using the Solcast API - making tomorrow’s solar production visible, actionable, and reliable - now one of their apps most used features.

Discover key insights from Solcast on how site measurements and fine-tuned models can make your PV forecasts more accurate and reliable.

Discover why moving beyond hourly Typical Meteorological Year (TMY) datasets to sub-hourly, multi-year Time series data is essential for accurate, risk adjusted financial modeling – and how this improves solar project returns.

Asset managers overseeing DER portfolios encounter persistent challenges with data acquisition and workflow efficiency. Physical pyranometers, while common in bigger sites, require frequent cleaning, calibration, and maintenance – increasing operational costs.

Discover why sub-hourly (15-minute) TMY data provides more accurate, bankable solar resource assessments than traditional 60-minute (8760) datasets. Learn how higher-resolution TMY data improves yield modeling, investment confidence, and risk management for solar projects.

October solar conditions varied across North America—strong high-pressure systems boosted irradiance in the East, while storms and Hurricane Melissa led to reduced output in the Pacific Northwest and Caribbean.

Solcast data highlights a sharp irradiance divide across Europe in October, with storms dampening northern generation and stable weather boosting solar output in the south.

Following months of above-average irradiance, eastern China and the Yellow Sea basin saw a sharp downturn in September, while other Asian regions stayed sunnier. See what’s driving this solar shift.
