365 CFM 5-Watt Solar Powered Roof Mounted Exhaust Fan for Storage Containers
Ventilation is key for storage containers. If you plan to store equipment you don't want to get rusted or damaged due to moisture and heat inside your storage container, you need to ventilate it sufficiently. Remember, that uniform air movement throughout your entire container is important. Solar power roof vents are a type of exhaust vents that make up half of a balanced ventilation system for your storage containers. You will need intake vents down low as well for fresh air to enter your container so the hotter air rises and exhausts out of the vent on your container's roof. Together they help remove any built-up heat and moisture inside your container for year-round ventilation.
This is not the most powerful fan but bigger isn’t always better. Other larger solar powered fans on the market are not only up to four times more expensive, they can actually circumvent the design and science behind the passive venting system. Once again, uniform air movement across the container length is the key to proper ventilation. Installing a single large solar or electric vent on a 40’ container instead of installing two of our solar fans leads to problems. Because the large fan pull air only from one spot and that leaves problematic hot spots inside your container. So bigger and more powerful is not the key to a properly vented container, multiple smaller solar fans like ours are the key for larger containers. Also smaller solar fans require less power to start operating so our fan will work even on slightly cloudy days and there's no need for an on/off switch or thermostat control.
This solar fan is excellent and sufficient at exhausting a 20’ shipping container, you would need two for a larger 40’ container. If your container is located at a hot and humid environment with little to no wind installing our 365 CFM Solar Powered Roof Mounted Exhaust Fans is the way to go instead of a turbine vent which needs wind to work to its max capacity. The solar panel provides energy to the fan on sunny days to increase the vent's CFM over and beyond a standard non-motorized static vent. It is made of rust free aluminum, 8” diameter exhaust fan with a 2”. collar height and 12”x12“ square flange that is design specifically to fit directly on to your shipping container roof corrugation. Just like all of our products this solar fan is designed to be quickly and safely installed with a strong water tight fit saving you time and money.
Once installed its low profile design looks pleasing on your container roof. It has a solid vent cap with an inner vertical louver cylinder to keep out insects, birds, and animals. The inner vertical louver allows air to exhaust without resistance. It is powder coated with an electrostatic charge in brown finish. The powder coating finish adheres extremely well and is more difficult to remove than wet paint which adds to the vents durability and long lasting clean appearance.

STOP! Before you start to install your Solar Powered Exhaust Fan please read the entire instructions. This product has sharp edges that can cut your hands. Wear canvas gloves during installation and handling. Use care when handling unit to prevent damage to solar panel. To ensure your safety, always use eyewear and hearing protection. Keep your hands clear of blades, grinding discs and drill bits. If you are not proficient in the use of power tools, you should find professional help to cut the hole.
Although for the most part they are even, every cargo container roof has slight deviations in the corrugated spacing. The rubber strips on our solar fan base are specifically designed to fit directly onto your shipping container roof corrugation and accommodate minor deviations. Just like all of our products it is designed to be quickly and safely installed with a strong water tight fit.
If you are installing one Solar Powered Exhaust Fan on a 20’ container the center of the 8’x20’ roof (10’ from each end of the container) where you should install it. If you are installing two Solar Powered Exhaust Fan on a 40’ container then each fan will be located 10’ from the closest end of the container and they will be 20’ apart. These measurements are recommended but do not have to be precise. You should check various locations on the roof to find the area that fits the best. Avoid seams and any place that looks uneven due to dents or heavy warping. Make sure you have all the tools and materials you will need. Check the weather, although the installation should take about 45 mins, allow yourself 1 to 2 hours to complete the installation.
Here is a list of tools/supplies you will need:
Grinder with 1/8” max thickness abrasive cutoff wheel (Reciprocating saw with metal cutting blade also can be used)
Drill, Center punch, Drill bit 3/16”
Rag, abrasive pad, pencil, masking tape, measuring tape, 5200 marine-grade adhesive sealant, caulk gun, gloves, ear and eye protection
- Once you have selected an adequate location to mount your solar fan, place it in the selected area, make sure the corrugations are centered as best as possible, and carefully pencil a line on the outside edge to mark location. This will be a 12”x12” square. Using painter’s masking tape, mask ¼” outside of the pencil mark. Mark the screw holes. Small gaps are OK, it will never be perfect but you should still proceed with the installation. The corrugation profile strips will conform to the container.
- Move the solar fan aside and take note of which way it is facing. When installing, the unit should face the same way to match the marked screw holes. Center punch the holes and drill them using 3/16” drill bit.
- Find the center of the 12”x12” square you pencil marked and draw an 8” diameter circle. This will be the hole that you will cut.
- Using a grinder with a maximum 1/8” thick cutting disc, start your cut then follow the line to cut the 8” diameter circle hole with your reciprocating saw. If the shipping container has been retrofitted with electricity or gas, make sure not to cut through the wires or pipes. You can also use a drill and bit same size as your reciprocating blade to start your cut. We highly recommend using the grinder with cutoff wheel. If you do not have a reciprocating saw you can cut your entire hole with the grinder.
- With the abrasive pad, thoroughly scuff the roof from the tape line to edge of the 8” diameter hole you just cut. This will prepare the roof to bond with the solar fan base.
- Using 5200 marine-grade adhesive sealant, apply two parallel 3/8” beads ½” from the masking tape and from the edge of the 8” diameter hole and another bead in between them. It is important to use enough adhesive to make a good seal. There should not be any thin areas as water will find its way through. Adhesive should ooze from 100% of all side edges when the screws are tightened. If you have some minor visible voids in adhesive, it is perfectly acceptable to back fill thoroughly with the 5200 marine-grade adhesive sealant.
- Using care, center the solar fan, lining it up with the previously marked and drilled holes, and ensure that the skylight is facing the same when you marked the holes.
- With the stainless steel machine screws (4 pcs 10-24 x 1-1/2" Phillips Truss Head and 10 pcs 10-24 x 3/4" Phillips Truss Head) and zinc plated steel nuts (14 pcs #10-24 Nylon Insert Hex Lock Nuts) provided, affix the solar fan by first loosely setting screws in to holes and putting the nuts. Longer screws (1-1/2") to be used where there is corrugation profile rubber strips between the aluminum flashing of the solar fan and the roof panel and the shorter ones (3/4") where the aluminum flashing of the solar fan is in contact with the roof panel directly. Starting with the center corrugations, half tighten all of the nuts alternating from one side to the next so that the flashing mount seats uniformly then tighten them completely in same order. You will need an extra hands inside the container to do this. If installed properly, there will be adhesive visible outside the flashing after the solar vent is screwed down to the roof.
- Use a stick or old credit card to remove excess adhesive.
- Remove masking
Congratulations on a job well done! These installation instructions allowed you to successfully and permanently install your 365 CFM 5-Watt Solar Powered Roof Mounted Exhaust Fan to your storage container. You will experience the benefits for years to come.
