The ecoCalm 12\" unit pairs two transparent bifacial 30W solar panels with a high-efficiency 12-inch fan and a rechargeable battery so ventilation continues through twilight and short cloudy periods. Its IP44-rated fan blades and long cable make it easy to mount in a window or wall for attics, sheds, chicken coops and small commercial or hobby greenhouses up to about 1600 ft³.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the solar power system keep the fan running day and night?\u003c\/h3\u003e\n\u003cp\u003eThe fan relies primarily on the bifacial solar panels that harvest sunlight from both faces, increasing generation in bright conditions. A built-in 5000mAh battery stores excess energy and supplies the fan for up to about six hours after a full charge, while an intelligent controller automatically switches power modes based on sunlight.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo 30W transparent bifacial panels — higher output in direct sun and reflective environments\u003c\/li\u003e\n  \u003cli\u003eAutomatic mode switching between solar and battery for uninterrupted operation\u003c\/li\u003e\n  \u003cli\u003e~6 hours runtime from battery after a full daytime charge (varies with sunlight)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat temperature control options are available and how do they work?\u003c\/h3\u003e\n\u003cp\u003eThe battery box includes an adjustable intelligent thermostat so the fan turns on or off at your chosen ambient temperature.

It suits anyone seeking an off-grid or lower-grid-dependence ventilation solution with adjustable temperature control and short-term battery backup. If you need higher-volume industrial ventilation or continuous multi-day off-sun operation, consider higher-capacity systems; for compact to medium spaces where sunlight is available most days, this unit offers a convenient, low-maintenance option.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How long does the battery run the fan after sunset?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: A fully charged 5000mAh battery typically powers the fan for around six hours; actual time depends on prior sunlight and fan speed.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I mount the solar panels separately from the fan?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the 14.8 ft cable allows flexible placement so panels can be positioned for optimal sun exposure apart from the fan.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"ecoCalm","offers":[{"title":"Default Title","offer_id":56801893286228,"sku":"B0F4X7RX39","price":391.47,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/2652\/4244\/files\/ecocalm-front-panel-and-fan.jpg?v=1786752382","url":"https:\/\/gardenluxe.co.uk\/products\/ecocalm-solar-exhaust-fan-12-for-greenhouse-dual-bifacial-panels-smart-thermostat-5000mah-battery","provider":"Gardenluxe Uk","version":"1.0","type":"link"}
