I'm trying to figure out how many solar panels I'd need to install to generate about 13 kWh of power per day. I know that production can vary based on location and sunlight exposure, but I'm looking for some general estimates or tips on how to calculate the number of panels I might need. Any thoughts or suggestions?

You might find using a tool like PVWatts really helpful for estimating your solar panel needs. If you're assuming about 5 hours of good sunlight exposure and a decent output of around 70% efficiency per hour, you'd probably need a system that's about 3.8 kW. Just keep in mind that local conditions might affect this, so be sure to adjust accordingly!
I'm in Greenland and don't have solar panels yet. How many watts should I be looking for if I only get 5 hours of sunlight from March to September?
I'm thinking of going off-grid myself, so this info is super useful!
