Modernize Launches ModSun Solar Cost Calculator for Homeowners Nationwide

Human-Centered Approach to Going Solar Leverages Industry-Leading Technology

July 26, 2016 (AUSTIN, Texas) -- Modernize, the online service that connects homeowners with contractors specializing in energy-efficient home improvement projects, today announced the launch of ModSun, an easy-to-use residential solar panel cost calculator focused on providing a transparent, human-centered approach to going solar.

Powered by the only solar resource with nationwide Light Detection and Ranging (LIDAR) data, ModSun accurately maps each square meter of a rooftops size, slope, orientation and average sunlight intensity on more than 70 million homes across all 50 states. After entering a homes address, ModSun instantly provides the homeowner with a 3D visualization of their rooftops solar energy potential and a personalized, user-friendly cost assessment for offsetting up to 100 percent of their homes electricity usage.

"With ModSun, we sought to truly understand an everyday homeowners thought process about going solar and use that insight to design a simple tool that answers their questions in a way thats upfront and easy to understand," said Jason Polka, CEO of Modernize.

ModSun calculates the output potential of a solar panel system and its total cost to the homeowner, accounting for current local electric rates, recommended system size based on energy usage and weather patterns, specific available federal and state incentives and detailed purchasing or financing options. By leveraging patented technology developed by Geostellar with support from the Department of Energys SunShot program, Modernizes ModSun translates complex geomatics data into a simple, intuitive experience for a homeowner to easily understand their unique costs and economic benefits of going solar.

"There are so many variables and data points involved in calculating an individual homes physical and economic potential for solar energy that presenting all this information can be intimidating to homeowners. ModSun empowers homeowners by focusing on helping them understand the most important information and guiding them down a path thats best for their needs," Polka said.

ModSun is free to use and is available now at Homeowners can view and share their homes results anonymously until theyre ready to speak with a Solar Specialist from Geostellar that can advise a cost-effective, vendor-neutral solution.
