Solar power system to operate 3 greenhouses — 6 exhaust fans
Solar power system to operate 3 greenhouses — 6 exhaust fans
Available
A solar power system to operate three greenhouses during the day: six (three-phase) exhaust fans and a cooling pump for each greenhouse, powered directly from the panels via a 380V 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
- 26 solar panels x 645 watts · 16.8 kW peak.
- 11 kW - 380 V frequency converter, with two inputs: panels and generator.
- 90 meters of 6mm DC cable.
- Panel connectors and protection fuses.
- Combiner box for panels.
The price includes the components mentioned above. Mounting structures from our factory (hot-dip galvanized steel) and installation for large systems are priced according to location. Generator not included.
What do you expect from her?
The approximate load is 7.8 kW, based on a 1.1 kW exhaust fan fan and a 0.37 kW cooling pump per house. The panels produce approximately 75 to 101 kWh per day, depending on the region, season, and panel cleanliness, with the exhaust fan fans running from morning until afternoon. For nighttime operation, we recommend a 15 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 tailored to its type. Please send us the number and power of the pumps, and we'll confirm the correct size before you order.

Frequently Asked Questions
Does the system work at night?
During the day it runs directly from the panels. At night you connect a generator to the transformer input and it runs from there, without batteries.
Does the price include the generator or batteries?
No. The price is for the components listed only (boards, frequency converter, cable, connectors, fuses, and junction box if present). The generator, chassis, and installation are not included in the price.
How do I know the right size?
The size depends on the number and power of the extractor fans. The measurements are calculated for a 1.1 kW three-phase extractor fan. If your extractor fans are larger, send us their specifications and we will confirm the size for you.
Are you running the cooling pump?
Yes, if it's a three-phase 380V connection on the same transformer. If it's a single-phase 220V connection, we provide a separate solution depending on its type.
