  • Solar Roofs, Shingles & Tiles
    Kelly Pickerel is Editor in Chief of Solar Power World and has been involved with publishing in the solar industry since 2011. She joined the SPW staff in 2014 and enjoys working on contractor profiles and hearing about new projects. Her areas of focus include solar panel manufacturing, energy storage, the Contractors Corner podcast and the development of Solar Power World’s annual Top Solar Contractors list. Kelly graduated from Kent State University with a degree in magazine journalism and lives in Northeast Ohio. This article was originally printed in Solar Power World and on solarpowerworldonline.com. The Latest on Solar Roofs, Solar Shingles and Solar Tiles By Kelly Pickerel There are many words used to describe unconventional solar PV technologies used on rooftops. Within the “building-applied” category — basically anything that isn’t traditional solar panels attached to racks — terms like solar roofs, solar shingles and solar tiles are becoming more common, especially after Elon Musk and Tesla announced their solar roof idea in 2016. While the Tesla solar roof has yet to show successful application besides a few pilot installations, there are plenty of building- applied solar products on the market right now for homeowners looking for some- thing different than the status solar quo. Rackless solar systems applied products, also using monocrystalline There are two building-applied solar veterans that solar panels that are bigger than the surrounding make what they call solar shingles but may be better shingles. The SunTegra Shingle is about 52 in. described as small, rectangular solar panels that long and 20 in.

  • EC Solar Ready Guidelines
    February 2020 Prepared by: Section 1 Section 2 Section 3 Section 4: Section 5: Section 6: Section 7: Section 8: Solar Ready Guidelines Section01 to Return to TOC Solar Ready Guidelines 1-1 By having the SolSmart designation at this elite level sends a signal to those folks that are aware in the solar industry that, OK, Eau Claire is a place that embraces solar that makes it effective to do that work here. Ned Noel, City of Eau Claire, Associate Planner 1-2 Solar Ready Guidelines The purpose of this City of Eau Claire Solar Ready guideline are to encourage long-term solar development within the community as well as by building owners to establish building performance expectations to share with architects and contractors with any future building construction project. This document is educational and does not replace, supersede, or represent State or City codes and ordinances. Contractors, designers, and building owners should become familiar with the requirements of all relevant building codes and ordinances. The City of Eau Claire has committed to transition away from a fossil fuel-based economy. In March 2018, the City established long-term goals of achieving 100% carbon neutrality and 100% renewable energy community-wide by 2050. In order to undertake this effort, the City has undertaken to develop the Renewable Energy Action Plan (REAP) to lay out a pathway to meet the City’s goals, including the increase of renewable energy generation and solar power installations throughout the City. This guide will help the community fulfill those objectives. The following REAP strategies relate to the information provided in this Solar Ready Guideline document: Promote on-site rooftop or ground-mount solar within the city.
