okay so i downloaded this mostly out of curiosity because we've been going back and forth about whether to put panels on the roof for like two years now... and honestly? this app kind of made the decision feel a lot less overwhelming. you just pick your country, punch in how many panels you're thinking about and their wattage, and it spits out this whole breakdown — daily energy, monthly savings, payback time, even how many trees worth of CO₂ you're offsetting. that last part is weirdly motivating actually...
the roof planner screen is probably my favorite thing. you get this grid where you can visualize the layout, see how much of your roof space gets used, what the total system size ends up being. it's not like a 3D render or anything fancy, but it gets the point across and it's... satisfying to play with?
where it gets a little wobbly for me is the profile setup. there are terms like PSH and PR that have little notes but i kept second-guessing whether i was entering the right values. the auto-fill from country selection helps a lot though, so you're not starting from zero. and then the results screen — the Mission Report — has like four buttons at the bottom and i wasn't sure which one to tap first. minor thing but it felt a little cluttered...
design-wise it's this whole space-and-dragon aesthetic which is... unexpected for a solar calculator? but it's charming in a weird way. the red and gold color scheme is bold. some of the contrast between text and background could be better i think, especially on the darker panels.
overall it does what it says it does and does it clearly. really useful if you're actually considering solar and want something more concrete than a spreadsheet.
