Q:I am thinking of building a new two car garage in Northern illinois, is it possible to make the garage doors solar powered and reliable?
How you provide solar power to your garage door opener depends on where the garage is located and whether you are on the grid. If there is already power from your house that is available, then a solar panel grid tie system for your house would of course include your garage. You can just connect your garage onto that system (it might even already be connected!). If you have a detached garage and want to start out with the garage, you may want to look into an off grid solar system with a solar battery backup, but this would be very expensive and not recommended--although it is possible. A third option for some folks who live in very sunny areas may want to consider a solar carport, which uses roof solar panels to charge the battery in an electric car, as well as powering garage lights and the garage door opener. Whichever option you choose, as long as the garage's roof isn't in the shade most of the time (you'll want to make sure there aren't trees or other obstructions south of it), you'll have enough power for not only the door opener but also garage lights.

Q:I have a 48VDC system that draws 20W every day, all day. What battery and solar charger combination would be best for me?
Off-grid solar panel systems are relatively easy to design if you gather all of the information that you need beforehand. Your location is going to tell you how much sun you can expect your solar panel system to receive.
The first thing to calculate is the AC and DC watt hours for your average total watt hours per day. For this calculation you will add up all the electrical loads that the power system will need to provide power for. You need to take into account the watts and how many hours per day you will be using the electrical equipment. Multiply that answer by how many days per week to come up with the watt hours per week. Make sure that if you have appliances like an air conditioner that you use only in one season, that you make sure that you figure that into your calculation. If you have any DC loads, then you have to take those into account as well.
You need a few other pieces of information to obtain the size of the solar panel system. Remember that if the system is far away from the inverter, you are going to lose some electricity along the way.
For your racking system, you will need to make sure you have the maximum wind speed for your location and snow loads. And for the batteries, how much backup power are you looking for. From this information, we will have a better idea of the size of the system and the other components for your system.

Q:can solar panels be charged with with artificial light
The short answer is yes, but why would you ever want to power a solar panel with artificial light. If you are talking about a calculator that you use at your desk, the office light will provide the light to make the tiny solar panel in the calculator work, even though most of the artificial light will be wasted. If you are talking about a 140 watt solar module, then you may have to rethink your approach, or buy a ton of incandescent lights.
