Off The Grid

I'm going to live off-grid. Read my blog and learn how to do it yourself!

Pros and cons of flexible solar panels

I bought my first solar panel (not taking into account the ones I had in my calculator or watch) in 2006 r., and it was a flexible 10 Wp (PowerFlex 10 from ICPSolar). With the charge controller I had and a typical lead-acid car battery, it was my first solar system I used in my RV (camper van).

At the moment I have in my RV two standard solar panels (laminated in glass) and lead-acid deep cycle batteries (as far as I remember, AGM – absorber glass mat – type). I used both the standard solar panels and the flexible ones, so I have an idea on what are the pros and cons of two types of solar panels. (more…)

  • My story about renewable energy sources begins in 2006 when I bought my Volkswagen RV/camper. At the end of summer that year I bought my first renewable energy source — the first solar panel. I wanted it to be a off-grid energy source for my first camping holidays, but only found out that such panels have many disadvantages.

    The panel I bought was rated at 10 W and 12 V. I connected it to an unused old car battery to store the solar energy, using a charge controller. While we were driving, the battery was charged from a lighter socket, and on the campsites I used the lighter plug to connect the controller to the solar panel. That’s right — the panel has a lighter socket that allows it to be used directly, without any battery.

    Here’s a photo I took when working on my first photovoltaic system. (more…)
