That’s a great question. I’ve used the joules to watts calculator on A1 SolarStore a few times myself, and it’s quite handy for basic conversions. However, for off-grid solar projects, I’d suggest double-checking your values with actual load estimations and solar production data based on your location. Especially in regions like ours, where Solar Panel Price in Pakistan and local efficiency factors play a big role, it’s better to be thorough. It’s a good tool for quick reference though!
