Photovoltaics (PV) in practice


If you intend to use low-power solar panels in practice, you should take into account - already at the initial stage of design - some key characteristics of this type of energy source. First of all, it is necessary to take into account in the project a large diurnal variation, which applies to the power obtained from the solar panel. Depending on the weather (cloud cover), as well as time of day and geographical location, the available power generated by the cell changes in a wide range. Therefore - in order to obtain stable supply voltage - it is necessary to use good DC/DC converters. On the other hand, it is worth to provide in the system a buffer power supply - a battery, which in the period of good sunshine will accumulate excess energy, so that the system (being the load of the panel) can use this reserve at night or in worse weather conditions.

Small solar panels at Botland store

In this category you will find a very wide range of low-power solar panels with dimensions ranging from a few to just over 25 cm, differing in both the nominal voltage generated and the level of output power. The smallest of them - a 0.4 W cell - generates a voltage of 5.5 V and is equipped with soldering pads for connecting wires. We also have another version of this cell, equipped with a short lead-out cable with a USB A type socket. Larger cells - e.g. with dimensions of 13.6 cm x 11 cm - are capable of generating power of 1 W (at 6 V), and the largest panel available in this category provides as much as 5 W of power and has a very useful form of a flexible sheet that can be easily mounted on various types of surfaces.

Ready-made solar system, mini-size

A very attractive solution, perfect for starting the adventure with photovoltaics, is a small module DFRobot with a 2 V/160 mA cell. The tiny board of dimensions of only 30 x 30 mm allows charging a lithium-polymer cell (1S, i.e. 3.7 V) with a current up to 100 mA via a micro USB cable or using the included waterproof low-power solar panel (50 x 50 mm). Very importantly, all the circuitry needed for reliable operation is on board, including the SPV1050 solar controller IC and USB charger.
