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

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

Solar Power and Angles of Panel

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

Solar Power and method to calculate panels

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

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

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.

Li-po, Li-ion Battery Capacity needed for given Load Currents, approximation calculator

Li-po, Li-ion Battery Capacity needed for given Load Currents, approximation calculator

This is a simplified battery capacity calculator to estimate the needed battery capacity if you have known load currents. You need to know: a. Time needed to run your loads in hours b. Load currents in A.

Battery run-time calculator for Li batteries

Battery run-time calculator for Li batteries


This is a simplified run-time calculator to estimate the run-time of your loads for Li batteries. You need to know: a. Battery capacity in mAh (mili Amp hours) b. Load currents in mA.

Please note 1Ah=1000mAh and 1A=1000mA. So if you have large car battery with 20Ah capacity, then put 20000  (mAh) as a number.
