How to use solar power for personal use
Normally, those who are connected to the commercial grid try to use their most energy-consuming appliances at night, when the electricity rate is the lowest. With solar panels you want to do the opposite: panels generate the maximum amount of energy at around noon, so this is the best time to turn on your washing. Solar panels provide you with a steady flow of electricity during the day, but usually you can't spend it all. Not all of us are home during the day, and we definitely don't use our devices all. Since spring and summer days are longer and the sun is higher, solar panels get more sunlight and give off more energy. On average, a solar panel system produces 40-50% more electricity in July-August than in November. If your panels are installed on the ground, cleaning them two-three times a year is a must. A while ago Google engineers conducted an experiment on a solar farm in California: they left some panels to collect dust for 15 month. Making sure your panels are working properly doesn't mean climbing up the roof every few months. While manufacturers recommend performing a visual inspection of your solar array once a.
