Likewatt is a French deeptech company founded in 2019, focused on developing self-consumption project sizing and analysis software for the renewable energy sector. Its core products include Optiwize Pro and Optiwize Leads: the former is used for techno-economic studies of solar PV, wind, and projects with or without storage, while the latter is an automated simulation service that can be embedded into a company website to convert visitors into qualified sales leads.
Based on the website content, Likewatt’s strengths lie in presales and solution modeling. Optiwize Pro emphasizes completing a full feasibility study in 3 minutes, with support for load curve generation, electricity usage and bill data retrieval, real-time scenario simulation, automatic optimization of the ideal PV plant capacity, and clear customer-facing presentation documents. It also covers emerging use cases such as virtual storage, batteries, collective self-consumption, EV charging stations, and solar trackers. Reports can include a company logo, charts, and comments; Optiwize Leads can be white-labeled to match a customer’s brand identity.
The official website does not disclose any specific plans, pricing, seat limits, project volume limits, or payment methods. It only provides options to request a demo and download materials. Before purchasing, buyers will need to confirm pricing, service scope, contract term, and whether a trial is available through the sales team.
Its advantages are strong vertical specialization and direct relevance to installers, design institutes, energy service companies, and sales teams. The product is built around “delivering proposals faster and persuading customers more effectively,” and it already has 2,000 daily users, more than 300 enterprise customers, and 30,000 project cases. Several user testimonials mention that it is easy to use and that support is responsive. The drawbacks are that the website does not explain key enterprise SaaS procurement details such as APIs, third-party integrations, permission systems, security certifications, or data storage locations, and pricing transparency is also limited.
Likewatt is better suited to PV/storage presales teams targeting the French or European market, commercial and industrial self-consumption project developers, and energy consultants. The website does not provide information about access from China, and payment methods and local service availability are also unclear. For deployment in China, buyers would still need to assess the French-language interface, compatibility with local electricity tariff policies, network connectivity, and alternatives. Comparable products include PVsyst, HelioScope, Aurora Solar, OpenSolar, and local Chinese PV design software.
