Solar Power Generation Updates
July 22
- It’s noon in July, and only 28W are being generated.
- At 12:15 pm 57W were being generated, and all lithium batteries were at 100 % capacity.
- At 5:00 pm input is zero, but all batteries are charged 100%.
July 23
The first summer I had a solar panel I moved it a lot. Changing the angle of the panel optimized the power being generated. However, it is heavy, the cables are cumbersome, and I broke some connections; I also have limited battery storage. So, this year I have picked one good location and angle, and kept the panel stationary. The power generated is adequate for my needs.
In order to manage the power that is generated, and stored, I want to know what times of day are good for generating power. That is the data I am collecting today.

Heat Dome powered solar panels; Okay to power my office, but not amazing!
I’m not sure why, but my 100 Watt solar panel is only generating, a maximum of, 55W during these sunniest of days…
There have been times when a tree branch moved, and caused a small amount of shade, but a large drop in Watts. Also its very hot in direct sun, so maybe that is affecting performance of the solar panel.
I think its time to wash down the panel. There’s definitely some bird poop, and dust. Input pre wash is 53 W…
There were THREE small bird poops on the solar panel! I washed them all off. Then, as I was returning to my office to check if there was any improvement in output – I tripped on the cables, and broke a connection. Suddenly the panel is generating zero watts, eep, but is nice and clean! I fiddled around with the connections, and now am generating 56W! This suggests that each bird poop was decreasing my power generation by 1W each.
Power generation has previously been in the high sixties. Maybe its the angle of the panel, and the sun. But I’m happy with 56W. All of my lithium ion batteries are 100% charged. I’m running a laptop, and a fan; these are drawing 61W. I will try to do some work on paper, and unplug the laptop later this afternoon. To make sure that my lithium ion batteries are at 100 at end of day.
4:30 pm solar input is 10W. There isn’t a cloud in the sky, but the sun has dropped down behind the trees.
July 1: As the heat dome moves eastward, the temperature has decreased, the skies are overcast, and solar power generation is 10W at noon. An odd day, because at 4:22, power generation was up to 27W
In the past, moving my panel around the garden has caused cable connectivity issues. So I am a bit cautious about doing that, and as long as my batteries are almost always 100% full, I don’t think there’s any need to manage the angles more closely. If I was generating more power; without increasing my storage capacity, my batteries would be continuously maxed out at 100%. Monitoring solar panel output is fun, but my office usage does not warrant more batteries, or more effort to track the angle of the sun.
I have never run out of solar power, for my office, in any season. Solar powered office is working well!
Exciting News!
Alison Edwards has been selected as a speaker at the Society for Technical Communication’s (STC’s) Technical Communication Summit Conference and Expo (5-9 June 2021). In 2021 the Summit will be entirely virtual.
I will be talking about tools for creating fundraising narratives. Explaining how to use the ‘Hero’s journey’ and ‘Logic Models’ to create narratives for donors/sponsors and funders (grant proposals).
My talk is titled ‘Slaying Dragons and logic’, I will also be submitting a proceedings paper.

If today is your 75th birthday; Edwards Technical Writing wishes you a very happy Semisesquicentennial!

A Solar Powered Office: How does that work?
I run a laptop, a second monitor, a desk fan, a desk light, and charge my phone on solar power. I can run a printer, but I try not to, because its a waste of energy when I can easily work on a screen.
What I bought:
- 100W solar panel ($248.29)
- twenty feet of solar extension ($41.29)
- Solar Connector to 8 mm Adapter Cable ($39.89)
- Jackery Explorer500 Portable Power Station ($666.66)
- Jackery Explorer160 Portable Power Station ($229.99)
I bought the explorer160 Power Station first, and decided that I wanted more power outlets, and more storage capacity; So I bought a second, bigger power station – the Explorer500. My original set-up cost less than $600, and was completely adequate for a home office. I have no regrets about buying a second power station, because I use it for camping, and when there is a blackout, or an earthquake, I will have power 🙂

I have both portable power generators sitting on my desk (see above) and switch the connector cable (from the solar panel) between them throughout the day. When the battery charge is 100% on one, I charge the other. I keep an eye on the battery levels to make sure neither one ever reaches zero.
I bought the solar panel from a local company, on the island, called ‘We Go Solar’, and am very happy with their service!
I bought the power stations from Amazon.ca
Jackery Explorer 500:
Lithium battery power: 518Wh/144,400mAh
battery capacity, 500W Rated Power and 1000W Surge Power from the pure-sine wave AC port.
Jackery Explorer 160:
can charge from USB Type-C, USB and AC outlet.
rechargeable lithium-ion batteries providing 167 watt-hours of energy storage.
The explorer 160 has a type C USB port, but does not have a pure sine wave inverter. The Jackery 500 has a pure sine wave inverter, and three USB ports, none of which are Type C.
Saronic 100Watt 12V Poly Crystaline Solar Panel, with cable and clips +taxes = $248.29 CAD

I am very happy with my solar powered office. I like that I can work during a blackout. I live and work in a seismically active area, and consider this to be part of my earthquake kit!
