Balcony Solar Recharge Time Calculator
Estimate how quickly a balcony solar setup can recharge a portable power station under realistic daily conditions. This is designed for apartment dwellers and urban backup planners who need a practical sense of recharge pace, not brochure-perfect solar claims.
How to use it: Enter your battery size, current state of charge, desired target charge, solar array wattage, and average full-sun hours per day. The calculator applies a system efficiency factor to reflect panel angle, cable losses, MPPT conversion, and imperfect sunlight. Real-world output can vary substantially with shade, season, temperature, and balcony orientation.
