Tiny 2-Cell Solar Panel Charges Batteries in Compact,
Off-Grid Devices
Design Note 491
Fran Hoffart
Introduction
Advances in low power electronics now allow placement
of battery-powered sensors and other devices in locations
far from the power grid. Ideally, for true grid independence,
the batteries should not need replacement, but instead be
recharged using locally available renewable energy, such
as solar power. This Design Note shows how to produce
a compact battery charger that operates from a small
2-cell solar panel. A unique feature of this design is that
the DC/DC converter uses power point control to extract
maximum power from the solar panel.
The Importance of Maximum Power Point Control
Although solar cells or solar panels are rated by power
output, a panelвЂ™s available power is hardly constant. Its
output power depends heavily on illumination, temperature
and on the load current drawn from the panel. To illustrate
this, Figure 1 shows the V-I characteristic of a 2-cell solar
panel at a constant illumination. The I-vs-V curve features
a relatively constant-current characteristic from shortcircuit (at the far left) to around 550mA load current, at …

DROPS WIRING DROPS To simplify the distribution of wireless communications for
instrumentation, monitoring and control applications, power supply
designers strive for device grid-independence. Batteries, the
immediately obvious solution, offer the illusion of grid independence,
but require replacement or recharging, which means eventual
connection to the grid and expensive human intervention and
maintenance. Enter energy harvesting, where energy is collected
from the instrumentвЂ™s immediate environment, offering perpetual
operation with no connection to the grid and minimal or no
maintenance requirements. CONNECTOR …
