Solar power calculator app

Is sunny design a good tool for calculating solar PV?

SMA's Sunny Design software is an incredibly powerful solar PV calculation tool. It's free to download and, when used to understand the relationship between a solar PV array, its location, and the sun, it's superb. SMA is the world's leading manufacturer of solar PV inverters and solar PV monitoring systems.

How can I Optimize my solar installation?

Analyze the solar performance of your installation. Optimize your project with precise and reliable data. Switching to geolocation by IP. Google Maps needs your permission for location access. Mounting position ? For fixed systems, the way modules are mounted will influence module temperature, which in turn affects efficiency.

Where can I find information on solar radiation and photovoltaic system performance?

PVGIS.COM provides information on solar radiation and photovoltaic system performance for any location in the world except the North and South Poles. The solar radiation and photovoltaic production will change if there are local hills or mountains that block sunlight during certain periods of the day.

What is Peak installed photovoltaic power (kWp)?

Peak installed photovoltaic power (kWp) ? This is the power that the manufacturer states that the photovoltaic array can produce under standard test conditions, which are a constant solar irradiance of 1000 W per square meter in the array plane, at an array temperature of 25°C. Peak power must be entered in peak kilowatt (kWp).

How much production loss can a solar panel make?

The various international studies including those of Sarah and Jordan KURTZ estimate an average production loss of 0.5% per year. You can reduce this production loss to 0.2% if the quality of the solar panels is exceptional. You can increase the loss from 0.8% to 1% if the solar panels chosen are of average quality!

How to choose a solar installation angle & azimuth?

If you have the possibility to choose the angle and azimuth or orientation of your mounting system for your solar installation, whether on a flat roof or on the ground (concrete slab), you will check the optimization both angle and azimuth. PVGIS24 can calculate optimal values for slope and aspect (assuming fixed angles throughout the year).
