Solar lighting system without batteries

Objective : to build a small solar lighting system without to store energy, composed  of solar panels, step-up module and leds.
Category : solar energy projects
Input : DC
Output : DC
Solar panels are only producing energy when they have access to the sun’s rays. The system is only producing power during day light. The amount of energy produced is not constant.
 The limitations of solar power generation are where energy storage comes in. A solar booster, in its  definition, is a device that is used to improve the output of a solar power.
Field of aplication : lighting basements and underground parkings during the day and energy recovery from continous lighting systems (replicated at large scale).
Materials used to build the small solar lighting system in this science project:
1.Small solar panels – 2 peaces
solar lighting system component

mini solar panel

Solar panel 0.5 W 5 V max.
A solar panel is an assembly of solar cells that can convert light directly into electricity (DC voltage). This conversion is achieved thanks to the so-called semiconductor material from which each solar cell is made.
The material most often used for solar cells is silicon. This material can occur in three forms:
  • monocrystalline silicon
  • polycrystalline (or multicrystalline) silicon
  • amorphous silicon

2. leds

The led is known for the low power consumption.
3. step-up booster
