I would like to get into solar power, more or less as an educational project.
I thought it would be great to set up a solar panel and recharge my tool batteries for "free." However, when I looked into the least expensive solar kit from Harbor Freight, it was about $150 for the setup. Looking into the numbers, I discovered that it cost me about 1-2 cents to recharge each of my tool batteries using grid power. That comes out to 7500 recharged batteries at the high end to make up that initial $150.00 investment.
Considering I recharge maybe 10 batteries per month on average, that comes out to a payback period of 62.5 years!
So, I did not buy the solar kit I was looking at just for its limited use of recharging tool batteries. Obviously, if a person lived off grid, you would have many uses for solar power and that would make solar a more viable option.
A few months ago, I watched a YouTube video where some guy was advocating most people would be better off with grid power, backed up by a battery bank power station and a gas/diesel generator in case the grid power goes down. In his example, his battery banks would keep his house running for about 3 days off grid. If grid power was still out at that time, he would run his generator for a few hours every day to recharge the battery bank. For his needs, he looked at spending about $70,000 for a whole house solar setup, or about $2,000 for a battery bank and generator setup.
For him, it made much more sense to go the battery bank and generator route. He was advocating that a battery bank backup system was a better economical solution for most people who have access to grid power. After all, if you have grid power, the chances of not having power for more than a day or two is pretty low. If you lived in hurricane zones, and maybe had to go a week or longer without grid power, the generator and a tank of diesel would last a long time.
My idea would be to have some kind of a portable battery bank that was plugged into my car's 12v outlet and recharging all the time while I'm driving. If the house lost grid power, I could just unplug the battery bank from the car and hook it up to my house power box.
At any rate, cooking chicken and veggies from a solar panel is pretty cool. Way to go!
I put 6 540w panels, 12 2v/720 ah batteries and 6 kw inverter for around 6500 eur which is $ 7150. I have a diesel 6 kw generator. my friends connected them for free. I don't use generator any more as it takes about 1 hour to fully charge batteries with solar panels.
I am 100% off grid. with electricity bills here and money they asked to bring the line to my house my payback is just 1 year.

It's in really good shape. No idea why they put it outside for free, except that maybe the young people today do all their reading on their smartphones?
I remember playing checkers with my grandpa when I was a young kid. I'm now in my 60's, but I still cherish those times together with him. I doubt young kids will feel the same about their smartphones years from now. It's just not the same playing a game with a machine compared to sharing time with someone who you care about. You are not making a chess table, per se, but rather you are making future memories for your youngest. Hope you play chess with your child and build those memories for them to remember when they get older.
