Solar Water Heating Program

General Program Overview

Oncor will provide cash incentives for the purchase and installation of solar water heating (SWH) systems in qualifying homes. Interested homeowners, renters, developers, and builders can participate by working with a SWH installer (Service Provider).

A SWH system uses the sun's energy to supplement a home's hot water supply for activities such as dishwashing, laundry, showers, etc. While a SWH system cannot replace a home's electric water heater, it can drastically reduce the electricity required for hot water needs, typically by 40% to 85%. The sun's energy is free and can reduce a home's electricity consumption in an environmentally-friendly way.

SWH systems can range in cost from a few thousand dollars to several thousand dollars depending upon the type of system installed. Incentives are paid to SWH installers; your bill from the installer will show the incentive as a deduction from the installation cost. Oncor's SWH Program reduces an installed system's costs by $600 to $1,500, based on the system's predicted performance. A SWH system really becomes an affordable investment when you combine Oncor's incentive with additional federal tax credits that may be available to you. You can find more information about the Program in our brochure.

Low-Income Incentive

As of June 2009, the 2009 calendar year budget for low-income incentives has been reserved completely. Qualifying customers will be able to apply for the low-income incentive on January 1, 2010. If additional funds become available before then, the Program will update this web page accordingly. Funds are still available in 2009 for the regular residential incentive.

Oncor provides enhanced cash incentives to Service Providers for the purchase and installation of solar water heating systems in a limited number of qualifying low-income homes. The low-income incentive covers 95% of system purchase and installation costs, with a maximum incentive of $3,800. Eligible costs include equipment costs and labor costs for onsite preparation, assembly, installation, and interconnection to piping and wiring.

In addition to the eligibility requirements for the regular incentive, residential properties applying for the low-income incentive must meet the following requirements:
