TenRes is a free renewable energy / solar system calculator aimed at the Bulgarian market. According to the page, users can get a techno-economic report in about 2 minutes, including roof analysis, ROI calculations, and connections to verified installers. It is better understood as an early-stage PV project assessment and installer-matching tool rather than a full enterprise-grade solar design platform.
The disclosed core features focus on three areas. First, solar system feasibility estimation, helping users quickly assess the economics of a rooftop PV project. Second, generation of a techno-economic report, with an emphasis on speed and readability. Third, connection to verified installers, turning online assessment results into offline implementation services. The main content does not mention project management, team collaboration, permission controls, historical report management, CRM, or quotation management, so it is not possible to judge whether it is suitable for complex organizational workflows.
The page clearly states that it is โcompletely free,โ which is its biggest attraction and makes it suitable for individual property owners or small and medium-sized businesses doing an initial evaluation. However, it does not currently disclose whether there is a paid version, installer lead fees, enterprise plans, or a commission-based model. Judging from the product format, it appears to be a web-based online tool, but there is no clear information about cloud deployment, private deployment, or self-hosting capabilities. Third-party integrations, APIs, developer support, payment methods, and data security or compliance information are also not mentioned in the main content.
Its advantages are a low barrier to use, a clearly defined use case, fast report generation, and the ability to connect calculations with installer resources. This makes it suitable for early-stage customer acquisition and demand validation in solar projects. The drawbacks are that public information is very limited: there is no explanation of the calculation model, data sources, report accuracy, compliance, or privacy practices, and there is also no introduction to the collaboration, permissions, integrations, or support systems commonly found in enterprise software.
TenRes is best suited for individuals, property owners, small businesses, and users in Bulgaria who are considering rooftop solar installation and want installer recommendations. For Chinese users, its target market, installer network, and calculation assumptions are clearly oriented toward Bulgaria, so its localization value is limited. The main content does not make it possible to determine access status from China, and payment information is not disclosed. If you need a tool for use in China or global projects, consider comparing it with PVsyst, HelioScope, Aurora Solar, SolarEdge Designer, or local PV design and quotation tools.
