More energy from photovoltaic panels with a MPPT technology

Good news for fans of self-handling of domestic electricity with solar panels.

are available on the market because the new charge controllers with " MPPT.

These regulators, which stands for "Maximum Power Point Tracking (MPPT), are able to manage and exploit the point of maximum power output of photovoltaic panel based on solar radiation it receives.

In practical terms, these new MPPT controllers are able to exploit (for charging the battery) the voltage (V) supplied from the solar panel and then not only the current (A) generated by the panel. So thanks to the combination of both components (V and A) generated by normal photovoltaic panels you get a greater availability of energy for the recharging of the order of 30% more .

Inoltre questi regolatori MPPT sono anche in grado di poter gestire i pannelli fotovoltaici a 24V (per esempio del tipo impiegato negli impianti connessi alla rete elettrica nazionale "conto energia") per caricare batterie a 12Volt.

Quindi niente più problemi di adattabilità dei pannelli fotovoltaici in base al tipo di accumulatore installato.

The use of these devices MPPT technology is therefore recommended as a substitute for a current PWM charge controllers (that use only the component instead of the current panel A), thus increasing both the efficiency of charging batteries +30 %, as both adapters to use any type of solar panel installations for "off-grid (stand-alone)."

Whats The Eyeshadow This 2010?

Puglia increasingly hot sun photovoltaic

L’ annuncio dates back a few days ago.
The production of electricity from photovoltaic source in Puglia arrived to cover the entire 20% domestic production.
A stunning result, which testifies to the ' impressive growth rate over the last two years has seen the PV in the region of Puglia.
growth rate that now requires the development of guidelines will set criteria and rules which balance the diffusion of renewable with the protection of the territory .
La bozza delle Linee Guida è attesa per la fine di settembre, ha rassicurato Loredana Capone , Vice Presidente della Regione ed Assessore allo Sviluppo Economico .

Environment: Ebook of the best books on paper

E’ il risultato di un’ analisi riportata da The environmental impact of Amazon’s Kindle della Cleantech Group .
Sono stati valutati, in particolare, gli impatti ambientali provocati da Kindle , Amazon's . It was discovered
greater environmental sustainability of ebook than paper books . The
conclusion, though predictable, is important, given the strong growth prospects the market ebook.
As evidence of this growth, there is the figure for all ' increase in sales recorded in August, from Bruno Editore Srl, leader of the absolute' electronic publishing in Italy: + 761% compared to August 2009 !
Trend di crescita confermato anche dall’aumento delle copie vendute , sempre ad agosto 2010 , da Investire nel Fotovoltaico , l’ebook che ho pubblicato proprio con la Bruno Editore : + 1.162% , rispetto ad agosto 2009 !
