This free tool tells you if you can install solar panels in your home and save money.

Installing solar panels to power your home is one of the most popular options for saving on your electricity bill with cleaner energy. However, it's not always as simple as just getting started, as you first need to know if your home's roof is suitable for such an investment.

To do this, there is a free and publicly available tool that helps calculate the solar potential of any building in Spain . Its name is IGN Solar, so We are going to explain what it is and how to use it.

How to know if you can install solar panels at home: this is how IGN Solar works

IGN Solar is an online platform developed by the National Geographic Institute (IGN) and published by the Ministry of Transport and Sustainable Mobility. It consists of an interactive map developed with official databases from various public agencies that guides those considering installing solar panels in their homes or businesses. It's quite simple to use.

Simply access it from a web browser, search for an address or postal code, and click on a building's roof . The tool then displays the roof's photovoltaic potential, indicating the most suitable areas for installing solar panels and the amount of energy they could generate throughout the year.

It also allows you to select different energy ranges, view annual production curves, and check optimal roof areas. It even has a simulator that can estimate installation costs and payback time , taking into account factors such as the number and type of panels. As if that weren't enough, it includes a dashboard with information on solar potential by municipality .

The good news is that it has been recently updated and includes new features such as new layers of information, average solar radiation in public buildings, and overall ground radiation across the country . So, if you're thinking about installing solar panels on your home, you now have a tool to see if it's worth it or not, with reliable data that can be easily and quickly consulted from your computer.
