Sustaining your solar power during endless cloudy months can be a challenge. Solar panels are very efficient but the bottom line is, if you live off grid you must be conservative during any cloudy days period! Many people have a misconception that one cannot sustain with panels during the winter. You can, you just need to be conservative about it and think outside the box. We are long over due for more panels since we had a long long cloud filled winter which was very unusual for our area. ONE must prepare for the out-of the ordinary. Although our system is properly fitted for us, this unexpected winter took many off griders by surprise. But regardless we made due and did just fine! Here are some simple tips for all off grid homesteads to consider in saving a little bit of juice during those long cloud cover days!
