A Solar First, Off-Grid Solar Powered Elevated Water Tower
Problem; how to power a new 2.0 million gallon elevated water tower after it had been determined an
electric utility easement could not be obtained to power the site. In addition, if an easement was
obtained the cost to install electric service would be extremely high.
Solution, install an Off-Grid Solar PV System.
This was the problem the City of Kansas City, MO Water Department faced when constructing a new
Elevated Water Tower. The project located Northeast of HWY 291 and I-435 in Kansas City, MO was
constructed to service the growing area’s water needs.
The Water Department contacted the Solar Design Studio to evaluate the situation and propose solution
options. The system had to be capable of powering the site’s electric loads, which included 24 hour
monitoring and control of water pumping equipment, and lighting.
After reviewing solution options, it was decided to install a ground mounted system comprised of 7 KW
of Solar PV Modules, 33 KWH of Battery Storage, 4 KW Inverter and optional generator interface.
Outback Power Systems equipment and Solar World Modules were selected because of their “industrial
strength” capability to exist in harsh environments and reliability.
The Solar Design Studio designed the system, provided all the equipment, as well as project
management and commissioning services. JeanCO LLC, Raymore, MO, constructed the array and
installed all equipment. The system was installed and operational in two weeks.
Elements of the business case for installing the solar included the following:
Cost to Install
On Going Monthly Utility Customer Charge
Solar
$55,000
$0.00
Utility
$100,000
$16.45
Monthly Energy Usage Charge Range
$0.00
$60 – $250
The solar option first capital cost was $45,000 less than the utility and there is no ongoing and escalating
monthly operational cost. The site has a regular monthly maintenance schedule and the solar system
maintenance is minimal and easily added to the routine, without additional cost. Battery replacement is
planned at 5 years. The cost to replace batteries was determined to be significantly less than the
monthly utility charges over a 5 year period.
Off-Grid Solar PV and MicroGrid systems can offer a businesses the option to reduce monthly
operational cost. The Solar Design Studio can show you how the financials and technical components
