Battery Reconditioning for Storing Electricity from a DIY Solar Panels System

When it comes to the DIY-er’s who build their own solar panels, one critical and important issue is the Battery Bank they need to consider in order to store the amount of electricity produced by the panels in order to get off the grid.
When you go for DIY option you should also think of DIY regarding your Battery Bank as you can’t afford just buying as many batteries as you need, because you will need about 30 batteries to go off the grid, and this is a substantial amount of money to spend!

Schematic Diagram of Battery in a Solar Panel System

Let’s calculate why you’ll need 30 batteries…
In the picture to the right you can see a simple diagram that shows a schematic configuration of 100 watt panel sending it’s electricity to a single typical car-battery.
7 hours of sunshine will allow 4 florescent bulbs (25 watt each) to light for 7 hours…
This can give you the basic idea behind how many batteries you will need and why I say that Battery Reconditioning is the only option you need to take into account when you want to get off the grid by building your own panels.
If you’d rather read e-books, here’s a good one on how To Recondition Old Batteries And Save Money.

If you were to make a basic calculation of what you will need to power your home, you will get to a conclusion that you need about 30-40 batteries to get off the grid, and you just can’t afford paying for it by simply buying these batteries.

  1. Grid tied solar systems are cheaper to install. But what most ppl don’t tell you, is that if the power goes out from the grid, your panels are useless. I’d suggest at least a small battery bank just in case to keep your system working at least on a smaller scale if the power does go out

  2. Very glad you e decided to organise your web page on the solar energy
    I am in Africa now working for UN but very interested in Solar power. Mali, the state I am right now, recently signed a contract to build a Solar plant.
    Best, Nikola
