The City of Warrenville is committed to encouraging residents and businesses to reduce consumable energy and protect our planet. The following information is provided to assist in the implementation of solar power improvements in the City of Warrenville.  

The City Council has directed Community Development Department staff to allocate its time and direct its efforts in a manner whereby it prioritizes the review and processing of those building permits and development applications that are most likely to result in the construction of solar installations in the City of Warrenville.

A typical rooftop solar energy system permit is generally issued within one week after the following required permit application materials are submitted to the Community Development Department. Systems not mounted on a roof may take additional time due to extra reviews.
  • A completed Building Permit application.
  • Electrical Contractor Registration application(not required for currently registered electricians).
  • Professionally drawn site plan with the plan showing where panels will be located, with dimensions.
  • Structural calculations signed and sealed by a licensed structural engineer that certifies the mounted building wall or roof is structurally sound and will bear the weight of the photovoltaic panels.
  • Provider/installer's photovoltaic system drawings and product documentation (see Photovoltaic Installation Plan Review Checklist below for examples). 
  • Construction plans in compliance with the 2015 International Solar Energy Provisions Code.

Permit Fee: $79.25 for residential, standard photovoltaic system. Total fee is payable when permit issued. Additional fees may be required for large-scale designs.

Required Inspections: Two inspections are typically required; (1) Rough Electric - before roof panels installed, (2) Final Electric - when installation complete. To schedule inspections, call 630-393-9050 one day before inspection requested.  The contractor must be present.

For detailed information, please refer to the City of Warrenville Photovoltaic Installation Plan Review Checklist.
