There are ways to power stuff via solar without going grid tied.
The real question with anything solar, comes down to the following:
1) Why?
2) NEEDS vd WANTS.
3) Are you seriously prepared to make lifestyle changes?
On points above:
1) Depending on the why, one can start on another way to reach your goal:
1.1) If power failures are the pressing need to resolve, you don’t need solar.
1.2) If you want to save money, then grid tied is the best way BUT …
1.3) With grid tied, if the grid goes down then your solar system goes off too, a safety feature.
1.4) If you want to go grid tied and cater for power failures, then you need batteries and a hybrid inverter system.
2) Their is a massive price difference NEEDS vs WANTS.
3) Solar systems work best when the sun shines, a wee little caveat one does not realise until it is too late. When is you power usage the most, day or evenings when all comes home?
3.1) If you need power in the evenings, the price tag goes up substantially.
3.2) Catering for bad weather is another issue to consider after the above points have been decided upon.
4) BEFORE you start on solar systems, you have to understand your loads, reduce them. The alternative is seriously more expensive ito panels, batteries and inverter.
I can share / help / guide with a few ideas, if anyone wants?
And I don’t make one cent, so the advice is free and Caveat Emptor applies at all times.
