I'm going to try to make this easy for you. Here is a setup that will provide you with some basic solar power. Don't expect to run your laptop 24/7 , but this will give you plenty of juice to get a few creature comforts in place and you'd probably be able to keep a business class laptop going all day with it.

• Find a conveniently hidden and inconspicuous place to hide the battery and charge controller. Mount them both securely. Make sure you still have access to this space as needed to monitor power.
  
• Run a line from the battery terminals to the battery ports on the charge controller.
  
• Mount the solar panel to the roof using the provided brackets. Make sure you seal that shit up to avoid springing leaks. Run the power from the solar panel to your inverter and hook up the cable to the solar ports on the charge controller. Seal that shit too.
  
• Mount the power inverter wherever you find it convenient. Run a line to the charge controller and mount it to the load ports.
  
  Try to avoid leaving exposed metal wiring at your connections and make sure you have all the positives and negatives matched up and you now have solar power.
  
  When putting this together, I opted for decent starter solar panel, charge controller, and battery. I skipped details such as multiple outlets, custom lighting, and vent fans because that will add more complication as you're wiring multiple things. You could always upgrade to those later.
  
  Down the road, depending on your needs you may want to upgrade to a 100AH battery (it's much larger and heavier so keep that in mind), add a 2-3 more of the 100W solar panels, and add a vent fan and LED lighting.
  
  Keep in mind that heating, cooling, and refrigeration will not be viable with this setup. To run a good fridge/freezer setup like this one, you'd need probably 200AH of storage and 300W of solar panels to be safe.
