One of the largest expenses in agriculture expenses is electricity.
With the increase in the cost of electric power for the AG sector, it’s more important and cost effective than ever to use energy more efficiently. Two areas where lots of energy is being used are pumping and refrigeration. We can look at your farm operations to see where most of the energy is consumed and how much money can be saved by making energy efficiency upgrades. Whether you’re involved with crops, dairy or livestock, Sustech can help you harness the sun for clean, economical solutions.
Solar Pumping System
Sustainable Technologies design and build solar energy systems and run your 3 phase pump. The VariSun™ Direct Solar Pumping Controller allows you to use direct solar energy to power your pump. Pumping water can be very costly month to month. Having an autonomous pumping system is like getting twenty years of free pumping and no electric bill. The Varisun system is fully scalable to match your pumping system. What’s unique about the Varisun pump controller is that it runs the pump speed at the maximum power point of the production of the solar panel. The direct solar operation means you’ll be pumping as long as there is sun. An added perk is that it qualifies for federal and state incentives.
Variable Frequency Drive
Save money instantly with the installation of a Variable Frequency Drive (VFD) on your motors. Is your pumping system working harder than necessary? Can the pump run using less energy? Does it make sense to upgrade the delivery system? Adding controls and timers save you money? VFDs are no brainers when it comes to upgrading your system. It pays for itself in about 1-2 years in energy savings. VFD make your motors soft start without the typical starting surge and high torque require to start each time.
VFD equipped motors can operate seamless. The can be equipped with Pressure transmitters, flow meter, irrigation controller and telemetry. See our Blog for more details about Variable Speed Pump Panels for California Ag.
Get control of your energy costs by reducing your electric bills. Irrigation is one of the largest users of electricity. Sustainable Technologies offers complete energy audits for agricultural industry. We recommend energy efficiency retrofits for lighting, cooling, and VFD motors. Energy efficient measures can improve your lighting, productivity, business image and morale. Farm energy efficiency studies can show you ways to save money immediately. Some factors that will affect the pumping efficiency are: a worn impeller, an underperforming motor, throttling valves and improper pipe sizing.
Off Grid / Hybrid Power
Off Grid pumping systems work in remote locations without a connection to the grid. These stand alone systems are used to operate any 3 phase motors. Off Grid does not require batteries, charger and invertor when using direct solar power. Varisun is a motor controller can operate motor from 3 -150HP.
24/7 operation is available. With innovations in battery technology we are able to operate systems longer once the sun goes down. Deep cell batteries have been available for years but costly. Now with Lithium ion batteries your system can be powered all the time
Another high usage of electricity is for cooling harvested crops. By using ECM’s (Electronically commutated motors) energy efficiency has never been better for refrigeration fan motors. Let’s us save you 35% or more on refrigeration cooling. By just changing out motors your walk-in cooler will run more efficiently. The payback on the installation can be seen immediately. Using the latest GreenWize products, we can help streamline your operating costs and give you the power to manage your energy efficiently.
