About Should photovoltaic panels be installed flat or tilted
For maximum output, the sweet spot for solar panels in the continental U.S. is facing roughly south and tilted between 15 and 40 degrees, according to the Department of Energy.

Angling solar panels is generally better than having them flat. Tilted panels optimize sunlight capture, especially if adjusted to your geographic latitude, increasing efficiency.
Solar panels should be tilted at a steeper angle to compensate for this.
In general, solar panels should be installed to where the sunlight hits them at as close to a perpendicular 90-degree angle for as long as possible during the day.
In the US, panels are generally installed vertically by default unless you have a flat roof which better allows for horizontal panels since they won’t protrude as much.

6 FAQs about [Should photovoltaic panels be installed flat or tilted ]
Should solar panels be tilted?
Even a relatively small adjustment off the ideal angle can result in substantial losses of solar exposure and output over the 25-30 year expected lifespan of a solar installation. For example, solar panels installed at a 40 degree tilt may produce 10-25% more electricity annually compared to horizontal panels in many locations.
Should solar panels be angled on a low angled roof?
Flush-mounting solar panels on a low-angled roof will produce less electricity and reduce solar savings. To receive exceptional solar savings, you’ll want your solar panels to be angled in a way that optimizes the sunlight exposure for that location. This is done by tilting your solar panels at the same angle as the latitude of your home.
Can solar panels be installed at a fixed angle?
However, most solar panels installed for home use are mounted on the roof at a fixed angle. Meaning, the process of changing the angle of your solar panels with each season can be quite difficult. There are systems that can be installed that will track the axis of the sun and adust the angle over time.
Are angling solar panels better than flat solar panels?
Angling solar panels is generally better than having them flat. Tilted panels optimize sunlight capture, especially if adjusted to your geographic latitude, increasing efficiency. Flat panels can accumulate debris and water, reducing performance and requiring more maintenance.
Should you install solar panels on a flat roof?
In most cases – provided you have an unshaded, north or east & west-facing roof (depending on location) that is has some incline – this is the most economical approach, and your solar power yield will not be significantly less than if the panels were installed at the ‘perfect’ angle and orientation. But what should you do if you have a flat roof?
What is the best tilt angle for solar panels?
Determining the ideal tilt angle for solar panels involves considering geographic latitude and the seasonal sun position. As a general rule, the panel tilt angle should roughly equal your latitude during winter when the sun's path is lowest. In summer when the sun is higher overhead, a shallower angle closer to horizontal can maximize exposure.
