Solar lamp

Solar lamps for use in rural situations often have the capability of providing a supply of electricity for other devices, such as for charging cell phones.

Solar panels are made out of layers of different materials, in order of glass, encapsulate, crystalline cells, back sheet, junction box and lastly frame.

A separator also exists between cathode and anode which stops the electrodes reacting together at the same time as allowing electrical charge to flow freely between the two.

[7] Batteries inside solar lamps usually use gel electrolyte technology with high performance in deep discharging, in order to enable use in extreme ranges of temperature.

[citation needed] This section also includes additional parts such as light controller, time controller, sound, temperature compensation, lighting protection, reverse polarity protection and AC transfer switches which ensure sensitive back-up loads work normally when outage occurs.

[citation needed] Solar lamps are easier for customers to install and maintain as they do not require an electricity cable.

[citation needed] Over 1 billion people around the globe lack electric lighting, which contributes to continued poverty.

[citation needed] Solar energy output is limited by weather and can be less effective if it is cloudy, wet, or winter.

[9] The use of solar energy minimises the creation of pollution indoors, where kerosene has been linked to cases of health issues.

When the nonprofit Unite to Light donated solar-lamps to schools in a remote region of Kwa Zulu Natal in South Africa, test scores and pass rates improved by over 30%.

Solar lights illuminate dark streets and pathways, enhancing public safety and reducing accidents.

Currently, over 40% of all sales of off-grid solar lighting products in Sub-Saharan Africa are conducted through PayGo, reaching almost 50% in Kenya and 65% in Rwanda.

A solar lamp chip includes microchip(R), B−, B+, S− and S+. S+ and S− are both connected to solar panels with wire, one of which has plus charge and the other minus charge. B− and B+ are attached to two batteries in this case. The light will be shown through the LED light when all of these are connected.
