About

With GeoT*SOL you can simulate the heat pump system to the minute in order to determine annual performance figures (COP) and contribution margins. The systems can have other heat generators such as gas condensing boilers and solar systems. Movovalent, monoenergetic and bivalent modes of operation can be selected for operation. The annual performance factor according to VDI 4650 is an important factor for comparing plants according to their efficiency. It forms the basis for many funding measures and approval procedures. GeoT*SOL calculates the profitability according to the recommendation of the Federal Association of the Solar Industry (BSW) taking into account the funding: comparison of the costs of the heat pump system with a comparison system; capital value and production costs (heat price); modified internal rate of return (MIRR), profit taking into account the reinvestment.

About

Solispec is a browser-based solar design and proposal tool for installers, PV designers, homeowners, distributors and mounting manufacturers. It combines site planning, structural checks and customer proposals. Users can model ground-mounted arrays and flat or pitched roofs, assess mounting structures for snow and wind loads, configure PV strings across MPPT inputs, and generate drawings, cutting lists and bills of materials. The software estimates PV generation and payback, shows tree and building shade in 3D, and creates branded proposals with multiple options, PDF export and a shareable acceptance link. Users can select manufacturer equipment or add their own products and prices. Homeowners can prepare preliminary plans, while professionals can manage projects and clients; Business adds team roles and engineer-review workflows. Structural outputs should be reviewed by a qualified professional before installation.
