Solar power system to operate 10 greenhouses — 20 exhaust fans
A solar power system to operate 10 greenhouses during the day: 20 three-phase exhaust fans and a cooling pump for each greenhouse, powered directly from the panels via a 380V frequency inverter, without batteries. The inverter also accepts generator input, allowing you to power the greenhouse at night using the generator. Delivery available to all regions of the Kingdom. System components: 80 solar panels x 645W x 51.6 kW peak; a 30 kW - 380V frequency inverter with two inputs: panels and generator; 230 meters of 6 mm DC cable; panel connectors and protection fuses; and a panel combiner box. The price includes the above components. Mounting structures are manufactured by our factory (hot-dip galvanized steel), and installation for larger systems is priced according to location. The generator is not included. What can you expect from it? The approximate load is 26 kW, based on a 1.1 kW exhaust fan and a 0.37 kW cooling pump per greenhouse. The panels produce approximately 232 to 310 kWh per day, depending on the region, season, and panel cleanliness. The exhaust fans operate from morning until afternoon. For nighttime operation, we recommend a 45 kVA generator or larger. The cooling pump operates on the same transformer if it's a three-phase system; if it's a single-phase 220V system, we provide a solution based on its type. Please send us the number and power rating of the exhaust fans, and we will confirm the appropriate size before you order.
