Solar Panels Not South Facing

When the sun shines onto the surface at an angle the panel will still generate electricity but it will be less effective.

Panels mounted on a standard pitch roof facing east or west will produce approximately 15 less output than panels mounted on a south facing roof of a standard pitch. You should also consider the age of your roof and how long until it will need replacement.

The flatter a south facing roof is i e. Typically solar panels perform best on south facing roofs with a slope between 15 and 40 degrees though other roofs may be suitable too. In sydney south facing solar panels will typically produce around 28 less energy than north facing panels and the steeper the roof the less electricity they will produce. We also took at look at a tilt angle of 40 for the south facing orientations mainly just to show that a south facing roof with a steep pitch is probably not a good place for solar panels.

Most solar panels are facing the wrong direction say scientists. One solution is to compensate by increasing the solar collector area either using more panels or larger collectors. Solar panels facing east or west won t get as much light as those on a southern facing roof. That captures the most solar energy over the course of the day which benefits the homeowner but.

The results backed us up on this theory showing poor. In northern hemisphere most solar panels point south. For years homeowners who bought solar panels were advised to mount them on the roof facing south.

But west facing panels are able to generate more even flow of electricity. Solar panels perform at their best when the sun is shining straight on to the panels. According to the concord consortium makers of energy3d solar energy modeling software a home in boston ma with panels that face west would get 80 of the electricity that a house with south facing panels would. The closer to horizontal the better it will be for solar.
