All Solar is a dedicated solar energy company based in Casper, Wyoming, with over 15 years of experience in the industry. They design and install residential and commercial solar panel systems, battery storage solutions, and also provide solar panel cleaning and repair services. All Solar became BBB Accredited in March 2024 and maintains a perfect 5.0-star Google rating across 116 reviews. Their focus on Wyoming's unique climate and energy landscape sets them apart. Solar installations in Wyoming face challenges that coastal or southern installers rarely encounter: heavy snow loads, high winds, extreme temperature swings, and long winter nights followed by intense summer sun. All Solar has built their design and installation practices around these realities. All Solar earned the number one ranking in Wyoming because they are exactly what this state's solar market needs: a dedicated, experienced solar company with deep local knowledge, strong customer reviews, and a commitment to the Wyoming market. In a state where the solar industry is still growing, All Solar has positioned themselves as the clear leader.

*Companies displaying 15 or more years in business are typically established electrical, roofing, or general contracting firms that expanded into solar installation in more recent years. The years shown may reflect the age of the parent organization or a strategic partner, not necessarily the solar division itself. This distinction is worth considering when comparing to dedicated solar installers, as purpose-built solar companies may offer more specialized expertise despite a shorter operating history.
