Good day to charge!

The Klingons say “Today is a good day to die!”.  For me, Today is a good day to charge!

It felt great to charge after not being able to charge for about 2+ weeks. I put my panel out and at first, it wasn’t getting much sun. I checked on it a few hours later and it was doing great. It doubled the input to about 50 Watts and the estimate of how long it would take to fill the battery was reduced dramatically.

The sun today allowed me to mostly charge my second smaller unit. I will be able to completely fill it tomorrow. Then I just need to buy a thick electrical cable and I will be able to run my laptops on the solar generator. I am thrilled. I am going to do the math to find out the thickness of the cable I need to buy.

Since the position of the sun has changed since summer charging it from another window is working much better for me. I will probably charge in two windows now when summer comes since I have two units. There is no rush to buy a second panel since I am still learning how the current panel will work to keep the bigger unit charged. Maybe in 2 months or so a new solar panel might be purchased. I will see how things go.

Putting the solar panel out when it is snowing/cold isn’t going to concern me. I have read that as a solar panel heats up it loses efficiency. That means that in some ways having a cooler panel will be more energy efficient. It charged pretty quickly in the summer sun. I wonder how it will stack up when it is not summer. I understand that you have less solar energy because of the position of the Earth relative to the sun, however, with two panels this probably won’t matter much.

If you have fixed panels on your roof, the solar designer takes the position of the sun in mind when they design it and try to optimize the position of the panels for all seasons. If you really want the most efficient solar panels, however, having them ground mounted on a pole that can track the sun is the most efficient. I have seen reports that say that this increases efficiency by up to 25% more. Which to me, pays off with the extra solar power you could sell for instance.

Every day that has a little sun, is a good day to charge.
