HelioScope is an online app for design and engineering of rooftop solar photovoltaic (PV) systems. While this tool originated in North America, it is increasingly used internationally across many regions.

High April solar resource levels in the UK and Germany drive new production records, while new capacity helps Spain hit record production despite below average resource in March

Amid the global disruption caused by the Covid-19 pandemic – and the wide-ranging impacts it has had throughout the solar supply chain, from manufacturing, to project development, to operations and maintenance (O&M) – one thing has become clear: Solar power is essential.

Below average solar irradiation between 2017-19 has a prolonged impact on solar project performance and returns - up to 10% in some regions

Due to the impact that surface albedo has in PV yield calculations (mostly when we talk about bifacial modules), we have noticed an increasing interest in knowing more about this parameter. These are the most typical questions we are receiving (with their corresponding answers):

We are proud to announce the release of Global Solar Atlas version 2.0. The new online app comes with updated data and new features that Solargis has developed for The World Bank.

One of first steps in the development of solar energy projects is a pre-feasibility study. A key requirement is to make decisions on basis of reliable data, with limited time and resources.

Bad data in equals bad data out. This well-known phrase is very relevant in a context of technical design and energy simulation of photovoltaic (PV) power plants. Most solar companies understand this and are carefully evaluating uncertainty of solar resource data used for feasibility purposes ...

To assess the solar resource or energy yield potential of a site, we model the solar resource/energy yield using best available information and methods. The resulting estimate is the P50 estimate, or in other words, the “best estimate”. P50 is essentially a statistical level of confidence suggesting that we expect to exceed the predicted solar resource/energy yield 50% of the time. However, ...

We’ve released a new tool that will allow Solargis users to request time series data for PV systems with trackers. You can choose from 4 types of tracker options: 1-axis horizontal, 1-axis inclined, 1-axis vertical, and 2-axis tracking. It is also possible to specify tracker rotation limits and enable/disable backtracking.

The old GOES-East satellite, also known as GOES-13, was launched to orbit in 2006. The data coverage is North and South Americas.

The process of estimating solar radiation data uncertainty can be sometimes unclear. We've tried to summarise in 4 simple steps.
