The basics of solar energy

Last updated: 23 June 2025

New to solar? You’re in the right place. This section covers the fundamentals—how solar energy works, where it comes from, and why it’s become one of the most important energy sources in the world. Simple, clear answers to get you started.

What is solar power?

Solar energy is the energy we get from the sun. It is a renewable source of energy that we can use to generate electricity for our homes, businesses, vehicles, and more.

How does solar energy work?

Solar energy works by capturing sunlight using some special devices called solar panels. These solar panels are made up of smaller components known as solar cells or photovoltaic (PV) cells. These cells can absorb the sunlight and generate electricity using the so-called photovoltaic effect. The movement of these electrons creates electricity. This electricity can then be used to power anything from a single appliance to an entire building.

What are the benefits of solar for Europe?

Solar energy brings wide-ranging benefits to Europe, not just for the environment, but for people, businesses, and entire communities. It’s clean, affordable, and can be generated locally. Solar power reduces carbon emissions, supports energy security, lowers electricity costs, and creates thousands of jobs across the continent. As Europe is striving to meet its climate targets, solar power is helping to build a more sustainable and resilient future.

How does solar strengthen Europe's energy independence?

By producing electricity locally, solar energy reduces the need to import fossil fuels. This helps Europe take control of its energy supply, protects against global price shocks, and increases the stability of our energy system—especially during times of crisis.

How does solar benefit homeowners?

During the energy crisis, some homes could reduce their energy bills by 22-64% with solar PV, and 62-84% with solar PV and a heat pump (Solar Powers Heat report, March 2023). With support from local or national schemes, installing solar is more affordable than ever – and a smart way to invest in your home’s future.

How does solar benefit businesses?

Businesses that install solar can lower their operating costs and protect themselves from volatile energy prices. It is also a great way to show climate leadership and meet sustainability targets. Learn how a business in Athens, Greece benefitted from investing in solar energy – click here

How does solar help the environment?

Solar energy produces clean electricity without burning fossil fuels. This means fewer emissions, cleaner air, and real progress towards meeting the EU’s 2030 climate targets and achieving climate neutrality by 2050.

How does make solar different from other forms of renewables?

Solar power is the most versatile energy source that exists – it can be installed on rooftops, fields, or even lakes. It works at all sizes, from a single panel in a shed to a solar farm powering a town. It has no moving parts, is low maintenance, and can be combined with farming or nature-friendly land use.

What kind of insurance protection is available in case of unexpected events?

Like your home or car, solar systems can also be insured. Insurance policies can cover damage from storms, theft, or equipment issues. Some policies also cover loss of income if the system stops working. A qualified installer or insurer can advise on the best options.

Can I charge my electric car with solar energy?

Yes, you can absolutely charge your electric car with solar energy, and more and more people are doing just that! If you have solar panels at home, you can use them to charge your car. It is a great way to save money and reduce your carbon footprint at the same time. Even if you don’t have solar panels, your car might still be charged with solar power if you charge it at places like work or shopping centres that use solar PV.
