On a tunnel-ventilated shed in June, the fans are the whole argument. How a poultry farm's cooling load shapes the solar and battery design, what a shed roof will and will not carry, and what to ask before signing.
Solar EPC & street lighting RFQ checklist (TXT)
A controlled poultry shed depends on ventilation, cooling, water, feeding and alarms. Agree interruption limits and emergency actions with the farm's animal-welfare and ventilation specialists before selecting the energy system.
Temperature, humidity, bird age, stocking and ventilation controls affect the profile. Model those operating conditions rather than assuming a perfect match with sunlight.
| Input | Evidence needed | Why it matters |
|---|---|---|
| Consumption | Twelve months of bills and representative interval demand | Separates direct use, exports and changing demand. |
| Generation | Location, layout, weather dataset and loss assumptions | Estimates output month by month. |
| Connection | Sanctioned load, transformer and utility requirements | Establishes eligible capacity and approval conditions. |
| Installed cost | Dated itemised quotation and exclusions | Includes roof work, connection and commissioning. |
| Operating cost | Maintenance, insurance and replacement assumptions | Avoids treating later electricity as cost-free. |
Compare grid-following PV, existing generator or UPS arrangements and a compatible storage system. If backup is required, specify the exact supported load and transfer performance; a hybrid product family name does not establish uninterrupted ventilation.
The farm manager and relevant specialists should prioritise fans, cooling, controllers, alarms, water and feeding according to actual welfare requirements. Do not assume drinkers or feeders can always wait. Size power and energy from the approved schedule.
Assess the light roof, purlins, fixings, wind exposure and weatherproofing. Use a mounting detail approved for the particular profile; non-penetrating clamps are not a universal solution for corrugated roofs.
The array layout also has to respect the shed itself. Tunnel ventilation depends on the inlet and ridge arrangement working as designed, and modules must not obstruct inlets or change the airflow pattern over the roof. Agree the layout with whoever specified the ventilation before it is fixed.
Identify the supplying utility or PBS from the bill and obtain its current application checklist and charges. An isolated off-grid supply still needs appropriate electrical and site design.
