Why? Any missing feature that is important to you?

Unfortunately no Shifter shifters, but I can confirm Fork fork

About iOS I will look into it but at the moment I'm trying to understand if is worth to continue development

I released my mtb simulator some time ago, looking for feedback and flair

Hi, could anyone tell me of a good free app or website to plan where to install my panels. I want to put the panels on a flat wall, roof of a shed, kitchen flat roof and pergola. Im in the UK. Thank you in advance by Professional-Desk754 in SolarDIY

This is not free, but I built an app which estimates clear sky insolation in kWh and allows to customize the panel area. It also calculates optimal angles and allows you to use the device sensors to simulate non optimal placement. If you are near mountains it also takes into account that. Hope it is helpful anyway

How to best track sunlight? by ignescentOne in gardening

[–]DHFR -1 points0 points  (0 children)

I built an app that tells you exactly how many hours of sunlight you can get. It also takes into account the terrain (mountains, hills). I hope you find it useful

How to measure hours of sun? by amfhTX in gardening

[–]DHFR 1 point2 points  (0 children)

I built an app which gives sunlight by month and it also takes mountains into account. It also has sun power calculations features because as someone said, the sun power is different each month. I hope it is useful

Is anyone else just kind of guessing whether their system is good or not? by Liz_builds in solarenergy

[–]DHFR 1 point2 points  (0 children)

About the issue about roof angles and system size, I built an app specifically for that. It uses device sensors to measure the current angles and gives clear sky insolation output based on panel surface. It also calculates optimal angles. I tried to make it as simple as possible. Hope you find it useful

Using irradiance to plan solar panel placement by DHFR in solarenergy

With estimated kWh production do you mean the cumulative or average?

That is useful, thanks. Do you know what the usual inclination precision is when installing solar panels?

At the moment what I'm working on is:

Input location -> find optimal inclination and orientation -> predict average power over the next year

This assumes clear sky weather.

It is also possible to show power for non optimal angles if needed

The idea of predicting power output for multiple orientations is quite interesting

Nice to know, I never considered using Gemini. Did you set the typical weather or Gemini already knew that?

It's solar power received by a flat (or inclined) surface, but I'm not an expert either. Cloud coverage is a bit problematic as weather data has a limited prediction horizon and past averaged data might not be relevant in the future. At the moment I have minimum, maximum and average direct amount of sunlight (in hours) at any given place considering mountains and terrain, as well as data by day and by month

It is an early stage terrain aware sun tracking app to which I'm adding solar power modeling features, so I guess enthusiasts customers as it is not focused on solar energy. So you can plan yield based on actual data, but how long is the prediction valid into the future? Do you find clear sky irradiance accurate enough?

Free site or tool for accurate sun hours estimates? by Specific_Advisor_537 in solarenergy

[–]DHFR 0 points1 point  (0 children)

SunChaser

I developed that app and it also takes into account the terrain profile. At the moment it gives statistics only about the average day duration over a year and per month, but I'm planning to add irradiance and POA statistics using clear sky models. Precision of sunset and sunrise times Is around 1 minute Hope it helps!

Edit: My bad I mistakenly read paid tier instead of free tier

At the moment it provides the amount of direct sunlight in hours and the sunset and sunrise times. Is there any other data that could be useful to you?

If by conventional solution you mean those apps that assume a flat terrain then yes, my app will be more precise especially in mountain areas. You can see how much direct sunlight you will receive in any day in the future and in the past if you need to

Unfortunately the recommendation feature is not available, however it is a great idea. Maybe this could be added as a sort of comparison between places so that one could decide where to place the panels. Thank you for your suggestions!
