Comme la demande pour la pose de panneaux solaires a fortement augmenté, surtout pour les installations plus vastes que les centrales de balcon, les carnets de commandes des entreprises dans le domaine du solaire sont pleins. Si vous demandez aujourd’hui un devis, vous risquez d’attendre un moment, si votre demande n’est pas tout simplement renvoyée à une date indéterminée. Une autre conséquence de cette explosion du solaire est que certaines entreprises pratiquent des prix très élevés pour réaliser des installations. Il y a pourtant une solution évidente et radicale contre les prix excessifs : Do it yourself comme le disent les Anglais. Le prix du matériel est actuellement abordable, c’est la période idéale pour ceux qui font le travail eux-mêmes. Ils ne pourraient pas réaliser davantage d’économies. À cela s’ajoutent la satisfaction de faire quelque chose d’utile, tant sur le plan économique qu’écologique, et le plaisir de construire soi-même. Dans ce numéro spécial, vous trouverez une large sélection de montages d’Elektor, du régulateur pour panneaux solaires à celui pour chauffe-eau solaire, en passant par le système d’orientation pour panneaux solaires. Ce numéro contient également des informations pratiques sur l’installation des panneaux solaires ainsi que la technologie qu’ils renferment.

The Elektor Zener Diode Tester is essentially a constant-current source that can be switched in steps from 1 to 50 mA. It can be used to test Z-diodes up to a maximum of 54 V. Thanks to a 60-V step-up converter, the device can be powered by the usual 5 to 12 V. The principle of this tester is straightforward. A Z-diode or other DUT (device under test, such as an LED) is biased by an adjustable current source. The voltage across the DUT can be measured with a multimeter. The voltage of most (small) Z-diodes is specified at a current of 5 mA. Depending on the application, the voltage at other currents can also be of interest. That is why six current settings are available: 1, 2, 5, 10, 20, and 50 mA. LEDs are often specified at a current of 20 mA. What can be tested is: Whether a Z-diode is defective (short circuit or high impedance). Whether a Z-diode exhibits the correct Z-voltage. How a Z-voltage changes with different currents. What exact voltage is present at an integrated voltage reference. Whether LEDs in a series chain differ in brightness (hence the 20 mA current). What the current gain is for different base currents in (power) transistors. The kit contains all parts listed in the bill of materials including PCB and enclosure.
