Properties of solar panel?
do solar panels have to be in direct sunlight?
- You're going to suffer a loss of output if you do. How much depends on your exact conditions. Standard window glass (which I assume you want to use) loses light through both absorption and reflection. It also retains heat. Silicon PV panels use special low-iron glass (without the green tinge) to minimize absorption, and some have anti-reflective coatings. They also lose output as the temperature goes up, and a window in front will retain heat. If your panel is behind a window with panes, it may suffer a serious loss of output due to selective shading of some cells in a string (the panel needs all cells in light to produce electricity). So yes and no. You can put a solar panel behind a window and it will work, but not as well (perhaps very poorly); how much you lose depends on the particulars.s
What are solar panels?
- The solar panel is that convert sunlight into electric. There are two kinds of solar panels, poly solar panel and mono solar panel.s

Run a air conditioner off solar panel?
- You can expect such an air conditioner to use something like 500 - 800 watts of power. The ET-P65420 20Wp solar panel produces at most 20 watts so you will need at least three of them. Since solar cells make DC (Direct Current) electricity, and air conditioners use Alternating Current (AC) electricity, you do need an inverter. The M20 is a 220 volt inverter, and I suspect you are looking at a window air conditioner that will probably use 0 volt power. And the M20 only puts out a maximum of 240 watts so you need one for each of the 3 or more solar panels you will have to use. So the first thing to do is shop for air conditioners, getting the most energy efficient model you can find, paying close attention to the voltage and wattage ratings in the owner's manual or on the UL label on the back. Say it is a 500 watt, 0V unit. You will need three solar panels and three 0 volt model inverters. Also note that the 20 watt rating of the solar panels if when the panel is facing DIRECTLY at the Sun. If you just lay them on the roof, then even if the roof is sloped at a good angle (30 degrees) and facing south, it will only produce the maximum power around noon. 4 hours before noon, unless to go up there and tip them up to face the morning Sun they will probably produce only about half that amount of power. So right there you either need a motorized mount to automatically follow the Sun or twice as many panels. However, if you are going to connect the solar panel(s) into the house power, so that it(they) merely supplement the power company power, then you can use any amount of panels, and the power company will supply whatever extra power you need. That requires a licensed electrician to do. Or if you want to just power the air conditioner directly from the solar panels without any interconnection to the house power, then you need to know a lot more about electricity that you appear to know.s
