Knowledge fuels change - Support energypedia!
For over 10 years, energypedia has been connecting energy experts around the world — helping them share knowledge, learn from each other, and accelerate the global energy transition.
Today, we ask for your support to keep this platform free and accessible to all.
Even a small contribution makes a big difference! If just 10–20% of our 60,000+ monthly visitors donated the equivalent of a cup of coffee — €5 — Energypedia would be fully funded for a whole year.
Is the knowledge you’ve gained through Energypedia this year worth €5 or more?
Your donation keeps the platform running, helps us create new knowledge products, and contributes directly to achieving SDG 7.
Thank you for your support, your donation, big or small, truly matters!
Solar Electric Technologies
Introduction
Solar energy can be converted directly or indirectly into electricity by the use of the solar electric technologies:
- DIRECT: With the use of photovoltaic modules.
- INDIRECT: With concentrating solar power.
Photovoltaics (PV) is the field of technology and research related to the application of solar cells for energy production by converting the solar radiation (sunlight, including sun ultra violet radiation) directly into electricity using the photovoltaic effect.
The PV systems can be grid conected or off grid. Off grid system or stand alone systems are the so called solar home systems (SHS).
In the case of concentrating solar power the solar radiation is concentrated into a small area. This heats up a flud that is used to power a heat engine conected to a generator to produce electricity.
Solar Bottle Bulbs
Solar bottle bulbs were first developed in Brazil and since then has been adopted in different parts of the world.
