We know you have a lot of questions about solar aeration, and we're here to answer them. Read through these commonly asked questions, and please don't hesitate to reach out to us with any additional questions.


How does it work?

Solar Aeration operates by converting sunlight into electric energy. An advanced controller optimizes the amount of energy harvested from the solar module(s).  The controller then drives a variable-speed, high-efficiency compressor according to the solar energy available.

Batteries have long been known as “the weak link in the chain” when it comes to renewable energy systems.  In addition to being expensive, they have a limited life-span and will need to be replaced every few years.  Batteries also contain chemicals and metals that must be properly recycled at the end of their useful life.

That will depend completely on your particular pond and what it is that you are hoping to accomplish.  While some folks may see a noticeable improvement after a week or two, others might need an entire season to “see” the difference.  That being said, fish will notice the improvement almost immediately.

Shipping/Lead Time/Trucks/Unloading

Our SD-Series aerators ship via LTL Truck on a single skid.  The delivery truck will need ample space to maneuver.  Limited access fees and/or lift-gate fees are an additional charge and are not included in standard freight quotes.

Orders are normally filled & ready for shipping within 1-2 business days.

Actual transit times vary from 1-5 days, depending on your location.

Typical skid weights range from 200lbs to well over 500lbs, depending on what you have ordered.  A forklift or tractor/skid-steer with forks is recommended.

Installation & Maintenance

Not difficult at all.  Once the pole is installed, most people are able to install a complete SD-4 system in 3-6hrs.  Only basic mechanical skills are needed.  If you can read a level and turn a wrench, you can install these systems.

Definitely not. The SD-Series was designed for straight-forward, simple installation.  There are only 2 snap-together wiring connections to make.

Only if you want to.  Most people install them as a DIY project.

Typical install time is just a few hours once the pole is installed.

Maximum Run Length will vary, depending on hose ID and water depth.  Under most conditions, hose lengths of 200-350ft of 3/8”ID hose works fine.

On most installations, the solar array & compressor unit are located within 10-20ft of the water.  This is not always the case.  Due to the flexible design of our solar aerators, it is possible to locate the array and/or the compressor remotely.

Our systems have proven over and over that our compressors are extremely durable.  The typical useful life of our compressors tends to be 5-6 years.  If your system is used year-round, we suggest replacing the compressors at no more than 5 years.  The benefits of pro-active maintenance cannot be stressed enough.

Super-Easy.  Our compressors can be changed in about 5 minutes.  You only need a Philips screwdriver for the mounting plate and a Standard screwdriver for the hose clamp.  The wiring harness simply plugs in.

For the post:  A posthole digger, level, wheelbarrow, hoe & shovel.

For the array:  ½” wrench, 9/16” wrench, tape measure.

In general, no – but this depends on what is in your water.  You should plan on pulling your diffusers up at the end of the first season for inspection.  If they need to be cleaned off, just spray them clean with a garden hose/nozzle.

It’s very fast & easy.  Just twist the top-half of the filter housing ¼” to the right and lift it off.  Remove the old filter and discard.  Drop in a new filter and twist the top-half back in place securely.  Filters should be checked every month and changed when dirty.

Yes.  Our diffusers ship with a 3/8” hose barb pre-installed.  We also include a ½” barb fitting for those that may need it.

Any location that uses aeration when ice is possible should be clearly marked with warning signs.  These warning signs must indicate the use of aeration and that there is Thin Ice.  In most parts of the country, these signs are required.

Our kits included everything needed other than a mounting pole, which can be sourced from any steel supplier.

Our Top of Pole solar racks are built using laser-cut & formed steel and extruded aluminum rails & beam.  The hardware is Stainless Steel.

Performance Questions

Yes.  Our controllers and compressors are very efficient and can operate under solar conditions that are far less than optimal.  When a system is equipped with dual solar panels, they will start running with as little as 6% sunlight.

Our compressors are capable of pumping compressed air down to approximately 58ft.  At this depth, however, the air flow rate will be fairly low.

They are very quiet and run smoothly, even at full speed.  Dual-compressor systems are hand-tuned during assembly to ensure superior operation and to minimize harmonics.  You can stand directly next to one of our aeration units (at full speed), and hold a normal conversation.

Definitely.  Systems with dual panels can run while it’s snowing or raining.

The SD-1 and SD-2 systems come standard with a single solar panel, while the SD-4 ships standard with dual solar panels.  The SD-1 & SD-2 operate extremely well with only a single panel.  The low-light performance of these units is improved dramatically by adding the 2nd panel upgrade.  The daily run times can be extended by several hours.

Yes.  Our diffusers are made using high-quality EPDM rubber and Stainless Steel.  They are unaffected by the harsh, corrosive conditions found in flowback water.

Yes.  They’ve been operating in salt water for years.  Our DB-36 diffusers were designed from the ground up to be capable of operating in brackish water, salt water and frac tank water.

Yes.  The SD-1 unit is perfect for septic tank oxygenation.  Units that are shipped for the purpose of septic aeration are customed tuned for the application.

Yes.  Our aerators work very well for rainwater collection systems.  Systems used for this purpose are typically equipped with an additional airline filter on the outlet.

Unlike other systems on the market that use small 36-cell solar panels, our systems are equipped with full-size, 60-cell solar panels.  We use the same panels that are used for solar power systems on homes & businesses.  Each panel measures approximately 40”wide x 65” high.

Sizing Questions

In generic terms, you use the following:  SD1 for 1 acre or less, the SD2 for up to 2 acres and the SD4 for lakes up to 5 acres.

While it’s true that sunlight is free, the equipment needed to turn sunlight into electrical energy isn’t.  It’s also true that the cost of solar energy has dropped dramatically over the last decade.  This still doesn’t make it “cheap”, depending on what that word means to different people.  The bottom line is that a solar aeration system has a lot of parts that conventional systems do not.  While some parts (like the solar panels) are clearly visible, others aren’t as obvious.  In addition to solar panels, there are several other major things that simply don’t exist in the old-fashioned world of grid-powered aeration. Controller circuit boards, circuit breakers and brushless compressors are a few.  Even though these systems do cost more up-front, they do still manage to pay for themselves several times over.  On the flip-side of this, the electricity costs associated with any AC-powered aerator will tend to cost the owner many times the original purchase price.  Solar units are also immune to inflation rates over time.

We stock the SD1, SD2 & SD4.  We also have solar-direct systems available that range from ½HP all the way up to a whopping 30HP!

General/Warranty Questions

Our aerators are 100% built in Wisconsin, including the enclosures, controllers and compressors.

The warranty on the SD-Series units is 5 years on non-wearable parts.  The compressors are covered by a 3-year warranty.  DB-36 diffusers are lifetime.

Yes, you must register your product in order for the warranty to be in effect.  Registration takes only a couple of minutes and can be done by visiting our website here.
