Man installing alternative energy photovoltaic solar panels on roof

Rooftop Solar

By the end of 2019, more than 2,900 IREA customers had rooftop solar systems interconnected to our grid, accounting for more than 17 megawatts of power. IREA welcomes additional generation interconnections and wants customers considering rooftop solar to be aware of the following:

• IREA does not require a contract with any rooftop solar vendor for solar panel installation within our service territory, nor does IREA require any of its customers to obtain rooftop solar generation. We accept all interconnection applications that meet the criteria listed in our Small Generation Interconnection Procedure (SGIP) or Qualifying Facility Large Generation Interconnection Procedure (LGIP), both of which can be found here.

• We have received reports of door-to-door and other solar sales personnel falsely claiming to be affiliated with IREA. We do not have agreements of any type with any solar providers granting either exclusive or non-exclusive business within our service territory, nor have we authorized any solar contractors to speak on our behalf.

• IREA is not at all against solar interconnections. We do, however, want our customers to have the most accurate information regarding rooftop solar, which is not always provided by rooftop solar companies. Some sales and installation personnel falsely blame IREA for their own company’s decision to not operate within IREA’s service territory. Also be wary of comments seen on social media, especially generalizations and mischaracterizations of IREA’s policy regarding solar. We do not and cannot prohibit solar providers from installing their products in our service territory. We also do not have a preferred company for rooftop solar installation, but do maintain a list of solar installers that have previously installed systems in our service territory, which can be viewed on this page.

• Our application for an interconnection describes net metering and qualified facilities in detail. That application can be found here.

Net metering is available to residential customers installing a system that is 10 kilowatts (AC) or less, and from which proposed annual solar production does not exceed 120% of the customer’s 12-month usage. If the system exceeds 10 kilowatts, it will not be net-metered, consistent with state law. A solar-generating customer with a system exceeding 10 kilowatts may still receive a monthly credit for any kilowatt-hours their system delivers to IREA at our avoided cost, which currently is 4.4 cents per kilowatt-hour. Our avoided cost is recalculated annually; the amount credited will be adjusted consistent with changes to the avoided cost.

• If your solar vendor is not familiar with IREA’s policies and procedures or our load factor adjustment (LFA), be sure to contact us to discuss how installation of solar may affect your monthly bill. More information regarding the LFA can be found here and here.

• Solar vendors often operate in multiple states with varying policies on interconnections and may not be familiar with IREA’s rate structure. When speaking with a rooftop solar vendor, request that any explanation of possible benefits be based specifically on IREA’s rate structure.

We urge customers to contact our Engineering Services department at (303) 688-3100, ext. 5302, before signing any agreement to purchase or lease a rooftop solar system. We will provide any interested customer an information packet that includes a cover letter, list of required documents, interconnection agreement and rules and regulations. This packet provides answers to most questions regarding generation interconnections and is essential reading for any IREA customer considering rooftop solar.

The following solar providers have installed systems in our service territory within the last two years. This list is provided for information purposes only. IREA does not recommend or endorse any given provider, regardless of whether they are listed below.  Customers are not limited to vendors on this list, however, as IREA accepts all applications that meet the criteria listed in our interconnection procedures.
