Calculator for Pmax solar panels with No Load Voltage (= Vos) and Short Circuit Current (Isc)

This is very simple calculator for wattage characterization of solar panels with No Load(Open Circuit) Voltage (= Vnl) and Short Circuit Current (Isc)

Preliminary report results

This is preliminary report

Solar Power and Angles of Panel

After many years of usage and research around this subject, I came to a few simple conclusions.

1. It is the best to simplify your solar energy system. This conclusion is also concern the solar tracking devises.

Solar Power and method to calculate panels in accordance to your load

Q. How big the solar panel shall be?

Answer: Starting point is to calculate power consumption of your house or devise.

Possible falures in Lithium batteries

Here I will try to briefly describe possible battery failures and why it happened.

Calculator for battery run time for Lead Acids batteries

This is a simplified battery capacity calculator for Lead acid batteries is using the Peukert's law.

Battery Capacity calculator. Dermines battery capacity (C) in ampere-hours (Ah) for 2 (two) sequential discharge events.

This calculator determines the total required battery capacity (C) in ampere-hours (Ah) for two sequential discharge events. It accounts for the load currents (I1, I2), discharge times (t1, t2), discharge rates (Rc1, Rc2), and includes corrections for non-linear effects in internal resistance at low states of charge (SoC).
