Solar has to do with the sun.
There are numerous ways to collect energy from the sun.
Solar Electric
No one does solar to beet the power company. Usually the reason someone puts in solar power is because they cannot get power in a particular place that needs some low voltage or they want some power that is renewable and reliable when there is nothing coming from the power company.
There is so much hype out there it is hard to tell what is the best deal. What would be nice is to find the best deals that makes the most sense for a particular need without having to become an electrical engineer or test two products we can't afford to find out we should have bought the third product we did not know about.
One System
The two technical things we discovered is solar is a low voltage and high current application where large gauge wire is needed. The other do not undercharge you batteries. Manufactures will tell you at least 14.7-14.8V is required for a 12V system.
There is a solar guy, Bob, who actually made a full time business out of fixing the messes other installers by using poor practices and bad component choices had created.
In addition to fixing our wiring problem he identified our charge controller as the principle problem in our system He's actually done the kind of experimentation and research to figure out what the reliable, cost effective components we were suppose to do. That was 6 years ago and we're still using the same RV setup with the batteries we had to replace going strong.
