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 Home Systems (SHS)
Solar home systems (SHS) are stand-alone photovoltaic systems. In rural areas that are not connected to the grid SHS can be used to meet a household's energy demand fulfilling basic electric needs. SHS usually operate at a rated voltage of 12 V direct current (DC) and provide power for low power DC appliances such as lights, radios and small TVs for about three to five hours a day.
SHS typically include one or more PV modules consisting of solar cells, a charge controller and at least one battery.
They can contribute to the improvement of the standard of living by
- reducing indoor air pollution as SHS replace kerosene lamps,
- providing lighting for home study,
- giving the possibility of working at night and
- facilitating the access to information and communication (radio, TV, mobile phone charging).
