Use of Near-Surface Geothermal Greatly Facilitated by Brand New GeoT*SOL basic

GeoT*SOL basic 1.0 is the new dynamic simulation program for the design and planning of heat pumps from Valentin Software, the internationally active manufacturer of software for the renewable energy sector.

GeoT*SOL basic 1.0 allows the simulation and design of classic heat pump systems, as well as heat pumps combined with solar thermal systems. Five essential system configurations that have been proven in practice can be selected, including geothermal probes for tapping heat from the ground. The annual coefficient of performance (ACOP) is calculated on the basis of a minute-step simulation of the whole heat pump system over the course of a year. As in all the programs from Valentin Software, global climate data sets are provided with GeoT*SOL basic.

System planning is carried out in single steps – from selecting the predefined systems to setting the requirements (heat, domestic hot water) and the design and dimensioning of the components (heat pump, heat source, storage tank, collector array) to the presentation of results, including a financial analysis. Corresponding heat pumps from leading manufacturers can be selected from the component databases. Monthly coefficients of performance as well as the annual course for relevant temperatures, useful heat and electrical energy can be presented graphically.

GeoT*SOL basic is now available in an English/German version. The program extends the solar thermal product line – internationally known via T*SOL® Pro and T*SOL® Expert – with software for geothermal. With GeoT*SOL users now have a useful additional tool providing planning support for heat pump systems design, component dimensioning, annual energy yield calculation and in determining the efficiency and emissions reduction in comparison to conventional systems.

Valentin Software

Looking back on 20 years of successful corporate history, Valentin Software has since become the world market leader in planning software for sustainable energy supply with the brands PV*SOL® and T*SOL® for dynamic simulation, design, yield and financial analysis of photovoltaic and solar thermal systems.

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
