Q. How big the solar panel shall be?
Answer: Starting point is to calculate power consumption of your house or devise.
Here I will try to briefly describe possible battery failures and why it happened.
This is a simplified battery capacity calculator for Lead acid batteries is using the Peukert's law.
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.
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.
note 1Ah=1000mAh and 1A=1000mA. So if you have large car battery with
20Ah capacity, then put 20000 (mAh) as a number.
This page will give you some basic knowledge about wires and also provide and few useful calculators for different electrical parameters, dependent on wire size.
Please note: WE DO NOT SELL WIRES.
Some people treat solar panel as a battery with exact or close to exact voltage. Solar panels are made to specific applications with specific voltage parameters and wattage.
Batteries, basics about batteries, Part!: Introduction and Vocabulary/Semantics
There are many other battery chemistry, each with their own advantages and disadvantages. Also batteries classified under their shapes. In the last few years a few geometrical shapes became very popular.
acid chemistry is fairly tolerant of overcharging, which allows
marketing organizations to get to extremely cheap chargers, even sealed
lead acid batteries can recycle the gasses produced to prevent damage to
the battery as long as the charge rate is slow. We offer a range of
chargers from inexpensive to very sophisticated, depending on the
requirements of the customer, but all of the chargers we sell
off-the-shelf are highly regulated sophisticated chargers that cannot
overcharge the battery.
