Energy Tip

When buying a new air conditioner, make sure it is properly sized and installed – bigger is not always better. Units with too large a capacity will cost you more and may decrease your home’s comfort.

The sun can translate into savings for Waverly Light and Power customers. We offer rebates to residents who install solar water heating systems. These rebate opportunities add to our energy efficiency rebate portfolio to help residents save energy - and money- on their utility bill. Pre-approval is needed to qualify for the rebate.


How Much Does it Cost

Solar water heating systems can provide long-term energy savings. Waverly Light and Power rebates, in conjuction with federal tax incentives, make it easier for residents to purchase and install these systems.

Average Installation Cost $11,000
Average Federal Tax Credit (30%) $3,300
Average WLP Rebate $1,500
Estimated Customer Cost $6,200

Environmental Benefits

With a solar water heater our customers are not only saving money, they are also saving the environment. A solar electric heater produces about a third of the carbon dioxide compared to a regular electric heater and a solar gas heater produces almost half as much carbon dioxide as a regular gas heater.

How to Qualify

  1. Residents must go through a pre-application process and obtain a county-issued permit prior to installing a solar water heating system. (Homeowners may choose any licensed, bonded contractor in Bremer County to perform the installation, which will be subject to an inspection by a county inspector)
  2. A separate inspection by Waverly Utilities is also required as a safeguard in order for homeowners to qualify for the rebate.
  3. Once approved, rebate amounts are based on the square footage of the solar panel system.
  4. Waverly Utilities will then issue rebate checks within 14 business days. Rebates will be issued on a first-come, first serve basis, and there is a limit of one rebate per address.

Tax Credit Opportunities

Federal tax credits are available to homeowners who install a solar water heating system. All ENERGY STAR® solar water heaters qualify. Utilities recommends you contact your tax advisor for details and updates at the time of your installation.

To Apply:

  • Use IRS Form 5695.
  • System must be placed in service before December 31, 2017.
  • At least half of the energy generated by the system must come from the sun.
  • Homeowners may only claim spending on the solar water heating system itself, not the household’s entire water heating system.
  • Credit is not available for expenses for swimming pools or hot tubs.
  • Water must be used in the dwelling.
  • System must be certified by the Solar Rating and Certification Corporation™ (SRCC).
