Compare Powerlily vs. Solispec

Powerlily serves as an integrated solar operating system that consolidates design, proposals, customer relationship management, permitting, field operations, invoicing, and fleet oversight within a unified platform. This system guides customers from initial engagement through design, sales, installation, and ongoing service without the need to recreate the same project across various tools. Teams have the ability to capture and qualify leads, maintain attribution, oversee solar-specific pipelines, and automate follow-ups based on real-time events. The platform's live 3D design feature accommodates roof, ground, carport, and commercial array configurations, incorporating stringing, setbacks, shading considerations, and an extensive 8,760-hour per-panel production simulation. Moreover, its battery analysis capability links usage patterns, tariffs, incentives, and financing options to detailed hour-by-hour storage behavior and overall long-term value. Powerlily also has the capacity to generate editable single-line diagrams, coordinated permit-ready plan sets, customized proposals, e-signatures, invoices, and field schedules from a singular project record, thereby streamlining the entire workflow. This comprehensive approach enhances efficiency and collaboration across all stages of the solar project lifecycle.

Solispec serves as an intuitive web-based tool designed for solar installers, PV designers, homeowners, distributors, and mounting manufacturers, facilitating the complete process of solar design and proposal generation. This platform integrates various functions, including site analysis, structural assessments, and customer proposals into one cohesive system. Users have the capability to design ground-mounted solar arrays and analyze both flat and pitched roofs while evaluating the structural integrity of mounting systems against snow and wind loads. Additionally, the software allows for the configuration of PV strings across MPPT inputs, and it can produce detailed drawings, cutting lists, and bills of materials. It also provides estimations for PV energy production and payback periods, visualizes shade from trees and buildings in 3D, and generates customized proposals that can be exported as PDFs or shared via a link for client acceptance. Users can choose from a range of manufacturer equipment or input their own products and pricing. Homeowners have the option to create preliminary designs, while professionals benefit from project and client management features, with the Business tier offering roles for team members and workflows for engineer reviews. However, it is crucial that all structural outputs undergo evaluation by a qualified professional prior to installation to ensure safety and compliance with regulations. This comprehensive approach not only enhances the efficiency of the design process but also empowers users with the tools necessary for effective project management.
