haha, I was thinking of my post and came back to change it and saw you already read it. I changed the word flaw because that was an incorrect word, my apologies. I think it was more a difference of opinion is what I should have said of which I shared such as easier to buy now that prices are so low. Yet if people's budget is extremely low creating your own panel is an economical way to go. I had a friend who did that and found it so tedious and difficult she regretted wasting her money and finally bought panels. Even though one lives on the grid one can learn to be aware of power usage and reduce where one can. One can learn a bit on management so one can reduce or be more prepared in a power outage. A generator does not always run everything in the home unless one bought a huge expensive back up generator. Our first system had a 3000-watt inverter and we switched to a 1500 watt sine wave. ( you are correct, be sure what you buy, some Chinese sine waves are junk) Grid power is sinewave. Our inverter determines the quality of power if you will. For what ever reason, I only briefly looked into it, computers, TV's etc run more effieciently, with less issues on sinewave. We bought ours 2 years ago and was like 800.00 possibly a lot cheaper now. Of course a 3000 watt sinewave would cost more. Typically you would want 3000 or more because one major appliance like a toaster can use 1500 watts. In the summer when we have sun power the freezer (100 watt unit)fridge (250 watts) watter pump (800 watts) need to run more often and we can consume on average 3000 watts in the day. So for a house on the grid 5-6 kWh per day is not bad. Possibly could get it down to 4000 watts per day. Our solar panels came out of Calgary, AB but not sure where they were manufactured. Our town provided batteries, again not sure of the manufacturer, I believe the USA. I can look into it if interested. It is a pleasure to talk with you, @alexdory. Good to see you have other articles on this topic. I feel it is very important so much so that this winter I am writing a book.
