20 years later

Post by JRHill »

I am so tired of click bait of movie stars 20 years later. #-o

So how are YOU better off than 20 years ago? Or are you? What (solar) did you learn?

A solar system is like storage space - whatever capacity you have you end up using it and need more.

Solar when advertised sounds wonderful. The reality is not so rosy. With practice and knowledge you learn how to harvest it.
Edit. Only started to play with solar in 2010.

Simple grid-tie systems (no battery) are just that - simple, maintenance free, no tech expertise required.

Once you add batteries for backup power, the equation changes considerably.

Off Grid Solar - in all but the most outlying cases, whatever it costs to get grid power, off grid solar will cost more.

I am one of those cases. A group of cabins about 1/3 of the way from the highway to my location got together and approached the local PUD. The quote was $250k but it would only be $125k split between those 4 or 5 cabins if the Fed would do the cost share. The cost share was declined. Needless to say it was dropped. But they did get CenturyLink to bury a copper cable bundle (no DSL).

The above wasn't a full 20 years ago. But one thing is for sure - I could buy a lot of lead batteries and fancy generator with fuel for a long time and still be way ahead. There is the fact that it would increase property values a tiny bit. But it would also bring a bunch a people into the area and the stuff that comes with them.

You don’t install off grid vs grid to save money.

I sure didn't. ROI v.s. grid cost wasn't even part of the decision. For me it was:
• Sidestep organizational incompetence and get power into our home in 1 week instead if 6 months.
• Not paying a monthly reminder of aforementioned organizational incompetence.
• Have responsibility and means for system reliability directly in the hands of the end uusers

That quote was result of conversation with the installer who did my update, 3rd set of batteries, Radians.
Just for perspective, when we bought, it would have been about $25k to make the grid available and I figured that just bought me the privilege of a $3-400 monthly bill forever. Now, 16 years later, complete replacement of my PV, replace my quad FXs with dual Radians, 3 sets of batteries, 5 generators, gallons and gallons of fuel … and I still wouldn’t change to grid.

With "heat domes" and major floods etc. becoming more frequent and severe, it appears governments should have been focusing on developing renewable energy 20 years ago.
