Μέγιστη εξοικονόμηση ενεργειακού κόστους

Οι γεννήτριες πετρελαίου συνδέονται συνήθως με υψηλό και μεταβαλλόμενο κόστος - ανάλογα με την τιμή του πετρελαίου, το κόστος μεταφοράς και τη φορολογία. Ανάλογα με την περιοχή, η τιμή του πετρελαίου αυτήν τη στιγμή φτάνει έως και τα 2,5€/kWh. Στον αντίποδα, το κόστος των φωτοβολταϊκών μειώνεται συνεχώς τα τελευταία χρόνια και ανέρχεται αυτή τη στιγμή στα 0,10€/kWh κατά μέσο όρο παγκοσμίως.

Όταν το κόστος παραγωγής ρεύματος ενός φωτοβολταϊκού συστήματος είναι χαμηλότερο από αυτό της γεννήτριας πετρελαίου, το σύστημα PV-Genset αποτελεί μια συμφέρουσα επένδυση.

Με τη λύση Fronius PV-Genset μπορούμε να συμβάλουμε σημαντικά στην εξοικονόμηση ενεργειακού κόστους, γιατί με κάθε kWh πετρελαίου που εξοικονομείται, εξοικονομούνται μετρητά. Ως εγκαταστάτες μπορείτε λοιπόν να πείσετε τους πελάτες σας με τον σύντομο χρόνο απόσβεσης και το μακροπρόθεσμα χαμηλό ενεργειακό κόστος.  

Έξυπνος έλεγχος του συστήματος pv-genset

Για να μπορεί να διασφαλιστεί η σταθερή λειτουργία ενός συστήματος PV-Genset, είναι απαραίτητο ένα βέλτιστο σύστημα ελέγχου των ενσωματωμένων εξαρτημάτων. Υπεύθυνος γι' αυτό είναι μεταξύ άλλων ο ελεγκτής Fronius PV-System Controller . Εξασφαλίζει την απρόσκοπτη λειτουργία του συστήματος, εγγυάται αξιόπιστες αποδόσεις και μέγιστη εξοικονόμηση ενεργειακού κόστους.

Η λύση PV-genset σε χρήση

Σύστημα PV-Genset στη Ζιμπάμπουε

Ένα καπνεργοστάσιο στη Ζιμπάμπουε χρησιμοποιεί ήδη εδώ και μερικά χρόνια ένα φωτοβολταϊκό σύστημα, συνδεδεμένο με μια γεννήτρια πετρελαίου 150 kVA. Η φυτεία εξοικονομεί με αυτό το σύστημα PV-Genset έως και το 60 % της προηγούμενης ημερήσιας κατανάλωσης καυσίμων – κατά μέσο όρο 100 l πετρελαίου ημερησίως. Το σύστημα εγκαταστάθηκε και τέθηκε σε λειτουργία με την υποστήριξη του OneStopSolar, από τον Fronius System Partner της περιοχής James Davy.

8.3 Articles or services supplied must be inspected by the OrderingParty immediately after delivery has been taken of them. Any defectsmust be reported to us immediately upon being discovered, in a writtennotice sent by letter, telefax or e-mail quoting the number and date ofthe order confirmation note, of the delivery note or of the invoice, andthe serial and commission numbers. If the Ordering Party omits to makethis immediate notification, it may no longer assert any warranty claimsor claims for compensatory damages on account either of the defectitself or of any misapprehension as to whether the delivery or servicewas free of defects. The notice must set out which delivered items orsupplied services are affected by the defects, what the defects consistof in detail, and under what concomitant circumstances these defectsoccurred. Every single defect must be exactly described. Any costs whichwe incur as a result of unjustified notices or notices that are otherwise at variance with the conditions of use are to be refunded tous by the Ordering Party.

8.4 In the case of corrective and preventive maintenance work, ourwarranty shall be limited to the services actually rendered. We shallonly warrant correct functioning of an installation, machine, Softwareor the like whose components were not all supplied by ourselves if weprovable have undertaken – despite the provision of certain componentsby the Ordering Party or by third parties – to manufacture theinstallation (or machine etc.) as a whole, and if the faulty functioningin question is not attributable to incorrect or incomplete informationfrom the Ordering Party.

8.5 Unless otherwise agreed, the warranty period shall be 24 months.From the beginning of the 13th month of this period, however, ourwarranty shall be limited to making available, free of charge, the itemsneeded for remedying the defects; from this time onwards, any warrantyclaims going beyond the above shall be inadmissible. This periodlimitation also applies to the supply of items deemed to be immovableand to work on items which are, or are deemed to be, immovable. Thewarranty period shall start to elapse upon the passage of risk inaccordance with Point 6. The Ordering Party must always prove thatdefects coming to light during the warranty period were already presentat the time of the passage of risk.

8.6 In cases where we do give warranty, we shall – at our owndiscretion and within a reasonable period of at least 4 weeks’ duration –either exchange the defective article itself, or its defectivecomponents, for a defect-free article or defect-free components, orremedy the defect(s), or grant the Ordering Party a reasonable reductionin price, or (unless the defect in question is a minor one) cancel thecontract. The warranty period is not prolonged by the exchange of theitem or of parts or components belonging to the item. If, however, theremainder of the warranty period – including that part of the periodduring which our warranty is limited to free provision of the requisitematerials in accordance with Point 8.5 – lasts for less than twelvemonths, then the warranty period for the exchanged items, parts orcomponents shall be extended to twelve months. The items, parts orcomponents thus exchanged shall become our property. We shall not refundthe costs for any actual or attempted remedying of a defect by theOrdering Party or by any third party.

8.7 To the extent that is necessary and may reasonably be expected ofthe Ordering Party, the object of delivery or performance, or thedefective part(s) thereof, are to be dispatched or shipped to usimmediately at our request, at the Ordering Party’s risk and expense,failing which any and all warranty obligation on our part shall become void.

8.8 The Ordering Party is not entitled to withhold payments onaccount of warranty claims or other counter-claims not recognised byourselves.

8.9 Warranty claims from the Ordering Party are excluded in caseswhere the installation, user and operating manuals provided byourselves, or to be requested from us by the Ordering Party, have notbeen observed, or where the user has not been (fully) obligated toobserve such instructions; if the installation work has not beenperformed properly and in accordance with the relevant Standards, and inparticular if was not carried out by licensed contractors; if anycorrective maintenance or other work has been performed on the object ofdelivery or performance without our consent; if it has been improperlyoperated or used, or operated despite its protective features beingfaulty, or taken out of the contract territory without our consent, orused contrary to our instructions or for purposes for which it is notintended; and, moreover, where defects are attributable to foreignobject damage, chemical influences, overvoltage, the conduct of thirdparties or to force majeure; the same applies in respect of naturalwear-and-tear.

8.10 Our warranty is also excluded in cases where we have beencontracted to carry out repair-orders, to alter or modify used items, orto supply such items.
