At What Angle Do Solar Panels Have To Be Positioned To Get The Most Efficiency?

I want to build a house and place solar panels on my roof. What angle do I need to build my roof at so I can just place solar panels flat on my roof? Which management does the solar panels need to be facing?

This depends on your latitude and where you are. If you’re in the northern hemisphere, it faces south, with a tilt management at the sun with respect to the average tilt of the earth. If you’re in the southern hemisphere, the solar panels (both photovoltaic and solar thermal) face north. If you’re on the equator, then they may lie flat on your roof. In US at a latitude of 40 degrees, you may want a tilt of about 20 degrees (because of change of seasons). You can alway angel the panels simpler than modifying an existing roof. Be sure NOT to shade any part of photovoltaic panels at ant time.

Here is a link for the optimum orientation of solar panels.
Rather than fixing them in place, you may want to consider being able to change the angle to optimize each season.

most efficeint would have a motorized system that pointed them toward the sun at all times.
