iSolergo lets you make the preliminary design of a photovoltaic system in a few minutes, with the energy analysis, the configuration of photovoltaic modules and inverters and evaluation of plant profitability. In preliminary inspection, the App uses the resources of the device to automatically determine location, orientation and inclination of the modules, in order to obtain a complete energy evaluation of the site, using the global database climate. So, you can proceed by selecting PV modules and their better coupling with the inverter you want. The application verifies all the conditions of consistency (voltage, current and power) between the inverter and string combinations proposed and used. Solergo can handle systems with inverter with more trackers connected to strings with different exposures. The software contains an extensive and multi-brand modules and inverters database, with all the technical characteristics necessary for the calculation of the production system, considering the losses due to thermal drift of the modules, mismatching, losses in DC and efficiency of the inverter. In few steps, choosing the installation situation, the method of connection and tariff iSolergo calculates the resulting revenues. Adding the typical costs for installation and management, with the overall economic analysis, you can evaluate the profitability of the system and the cash flows resulting. All the calculations are shown on charts and tables easy to understand, to provide the potential customer all the information clearly and complete. All project data are stored on a file standard Solergo (software for the complete design of photovoltaic systems), and can be sent directly or via e-mail to your office computer.

Simple and accurate determination of the optimal PV tilt angle. Make your PV System generates maximum electricity for your desired location. The wrong position of your PV System can cause losses in electricity generation and your project feasibility may be a question. With this App you will obtain: - Solar Data charts (elevation, azimuth, sunrise, sunset time, noon time, sunlight duration, etc.) - Tilt vs azimuth optimization (find the ideal tilt angle for any chosen azimuth) - Optimal Tilt angle for any desired location on the map - Optimal orientation - Optimal monthly tilt angle - Optimal daily tilt angle - Optimal hourly tilt angle - On-site inclinometer for measuring angles The tilt angle of the panels is one of the most important parameters for your PV system. It is the angle at which the photovoltaic panels are set to face the sun relative to a horizontal position. The panels must have appropriate tilt angle, set for gaining maximum possible electricity from your PV system for your location. PV Solar Tilt is using optimization model for obtaining the most appropriate tilt angle of your panels in order to gain maximum electricity generation from your system. The model is based on sophisticated simulations for maximizing energy yield for a given location. If you need any assistance or clarification, please let us know at support@pvsolcast.com.

Verdict

The call

The clearest difference is in-app purchases: iSolergo at none against PV Solar Tilt's 1. iSolergo also leads on ads (none vs shown) and iOS requirement (11.0 vs 13.0). PV Solar Tilt's advantage is update cadence (every 4 months vs every 9 months). On price and device support there is nothing between them.
