Our island is 19.6 miles long and 6 miles across, with a total area of 70 square miles. We\u2019re located just below the hurricane belt, and unlike many islands in the Caribbean, our climate is dry, so we rarely have a rainy day.&#8221;<!--more--><\/p>\n<p><strong>Solar solution<\/strong><\/p>\n<p>The description above sounds like a perfect place for a solar installation and indeed it is. Recently Rob Fijn, got in touch to update us on this solar project after its initial year in operation.<\/p>\n<p>But why you may ask was an off-grid solar system required in a windpark in the first place? Two years ago <a href=\"http:\/\/imtech.com\/EN\/Marine\/\" target=\"_blank\" rel=\"noopener noreferrer\">Imtech Marine Curacao NV<\/a> received a request to provide a solution for an off-grid solar installation for NuCapital, to support the windpark onsite maintenance team working on the 10 x 3.0 MW Vestas V-90 turbines. The turbines have been operational since December 31, 2009, but the maintenance team office and workshop had no grid connection and it was too far away from any other grid supply. A solar solution was clearly the best option, plus the existing generator could provide back-up for the proposed solar system.<\/p>\n<p><strong>Design brief<\/strong><\/p>\n<p>The electricity supply requirements were for:<\/p>\n<ul>\n<li>An office\/workshop with 3 split air conditioning units, fridge, microwave, coffee machine, printer plus small hand tools<\/li>\n<li>Office work to be carried out mainly in the daytime<\/li>\n<li>At night, batteries will be required for the lighting, fridge and one or possibly two air conditioning units<\/li>\n<li>This is also to ensure that the day time maintenance crew have cool drinks and ice, as the temperatures inside the wind turbines can reach 45 \u00b0C at 10:00 am<\/li>\n<\/ul>\n<p><strong> Equipment specified<\/strong><\/p>\n<p>In considering the above, 80m\u00b2 of solar panels were specified and fitted to a sloping roof, as shown in the headline image above.

For example, a company installed a new air conditioning unit for the office and this was noticed immediately via the VRM, as L3 showed there was negative power on that line of -93 Watts outside working hours. The\u00a0air conditioning company were recalled, the problem explained and corrected. Just one of the benefits of 24\/7 remote monitoring.<\/p>\n<p><strong>Conclusion<\/strong><\/p>\n<p>Over the last year and four months the system has run perfectly and proved itself as a robust and reliable solution. Even in tests to replicate a fault such as a shut down in the backup generator, the Quattros continue to supply power via the GEL batteries until such time as the batteries reach a critically low voltage. To protect the batteries the Quattros then automatically shut down the load. When the sun starts to shine, the system then comes alive again as the MPPTs charge the batteries and the Quattros automatically switch the load on again.<\/p>\n<p>If you have an interesting project like this, do let us know and I&#8217;ll be happy to write a blog for you.<\/p>\n<p><a href=\"http:\/\/john.rushworth.com\/\" target=\"_blank\" rel=\"noopener noreferrer\">John Rushworth<\/a><\/p>\n<p><strong>Credits<\/strong><\/p>\n<p>Thanks to Rob Fijn for the technical information and photographs.
