Wind generators are less suitable around here, both because of possible noise, and less favorable wind condition.

I recently bought (not yet mounted) six 300W solar panels that will charge a 24V battery bank proividing LED light all over the house (replacing practically all AC based light), as well as a number of medium capacity ventilation fans. During a couple winter months, especially when the panels are covered by snow, they will not provide enough power, so the batteries are kept charged from the power grid by a unit that also provides UPC for my PC. And for my internet fiber connection - I asked my IPC about their provisions in case of power breakdown, and I was honestly impressed by their switft and complete answer.

For keeping my house warm: I "happened to" end up with a spare basement room of about 25 cubic meters, suitable for being filled with water. One cubic meter of water, raised in temperature by 1 degree Celsius, holds roughly 1 kWh of heat. So 25 cubic meters raised by 40 C holds 1000 kWh. Using the heat pump as a drain, I make that that temperature range run from 40C to 0C. If I need more: By freezing the water; I can in principle pull out anothter 2000 kWh before I have 25 cubic meters of solic ice...

The heat source for this water tank is a set of thermal solar collectors, providing at least four times as much energy for the same collector area as solar cells. They "recharge" my water tank continously throughout the winter when there is a sunny day. The cooler my water tank is, the higher the efficiency. When the tank is close to freezing, any heat from the thermal solar collectors above that temperature (and that doesn't take much) contribute to keep the water tank warm, making conditions very favorable for the heat pump. The thermal collectors are angeled at 60 degrees vertically, so generally, the snow runs off them.

The heat pump also has a ground collector for use if the water tank is close to freezing, roughly 400 square meters at a depth of 1 to 3 meters. I do not yet have any experience to tell when heat collection should switch from tank heat to ground heat or vice versa. I guess it depends a lot on the thermal conductivity of the ground and on the insulaton of the water tank.

The heat pump does rely on electricity. For shorter breaks, up to a few hours, this is not a problem: An accumulator tank in floor circuit has enough heat to keep the house heated for quite a few hours. Throughout fall, and from early in spring, the thermal solar collectors will heat the accumulator tank directly, in case of a power fallout. The circulation pumps of the floor circuits are run from the solar powered battery bank.

Some people think I am going too far ...

In this country, trying to be permanently off-grid makes you a Prepper, in the slightly negative sense. Creating your one-household power grid doesn't really make sense. Preparing yourself for a week without community supplied power makes a lot more sense.

Sidetrack (or is it?):

A few years ago, I became frustrated because I couldn't fix my car myself but had to run to others for help. Then I started thinking of all the other things that I couldn't handle myself... Quite a lot, really! For myself, I created at literally world, my own novel, of how it would look like if I had to manage on my own, all those who "knew" was killed by a virus. I imagined a situation where the only survivors were myself and a few kids. How would I maange? ... After developing this epic, considering all the consequences, I shake my heat at practically all "preppers": Too bad for you, but what you are doing has next to no value in a long term perspective.

You should grade your preparations: Some are for handling a shortage of your favorite peanut butter at the grocery store Some are for a two hour power shortage. Some are for your gas supplier going bankrupt so he can't fill your tank. ... and so on. It is all up to you. The scale goes all the way up to those who become prepper heroes on national TV.
