Hi GasCap,
Learn what you need before you go to a solar place. DIY can save 50% of the cost. If you can not DIY find an electrician who will install for you. Solar places want huge mark ups. Their labor rates are high and their expertise in general is low. The worst possible place to buy and install is an RV dealership.
Here is a simple flow chart.
Budget-->Energy Audit-->Battery bank size-->number of watts-->PWM or MPPT. What ever type of controller is chosen, make sure it has adjustable set points and a temperature probe that is on the battery.
One rule of thumb is between 60 and 150 watts of panels per 100 amp-hours of storage. The smaller the battery bank the higher the wattage needed (per 100 amp-hours). Here is a link to the rather special spreadsheet which includes an energy audit, that N8GS has created to help size solar battery charging systems!

Solar panel is my top priority add-on. Will definitely get them to install one for me. Also because of the noisy level on solar panels NONE! I believe there are no quiet generators with my research...
Go west told me it is 5500 to install a generator... I am pretty sure a top solar setup will cost me about ~2500? Max Out
