Solar Panels South Facing Wall

In northern hemisphere most solar panels point south.

Solar panels south facing wall.

See the chart below for a production breakdown. It is worth concederation and limited studies. The same installation with vertical solar panels however will produce 4 173 kwh each year a drop of 32 in yearly production. The diagram shows how the sun passes over a house with solar panels on the south and west facing roof surfaces.

Solar panel orientation in the uk. When the sun shines onto the surface at an angle the panel will still generate electricity but it will be less effective. Your solar panel orientation is very important when it comes to maximising the amount of electricity that your solar panels will produce. Solar panels perform at their best when the sun is shining straight on to the panels.

One solution is to compensate by increasing the solar collector area either using more panels or larger collectors. It is relatively shade free. If your roof doesn t face due south you could install solar modules on a south facing wall instead. Installers have adapted pre existing mounting and racking technology or developed their own to install solar panels on the south facing walls of buildings.

This will only work if the wall receives lots of direct sunlight i e. What happens if your roof isn t facing south. Even if i had the newer high tech solar panels and i only got 50 to 30 compasity it is better than nothing. The sun rises at 5 52 am and begins directly shining on the south facing panels at 8 15.

Let s walk you through an average day august 6th to be exact. Most solar panels are facing the wrong direction say scientists. Wall mounted vertical panels are still an energy generating option for solar installers. Trees bushes or other buildings that cast shadows on the wall will make the solar panels less efficient.

A south facing 5kw installation in minnesota with solar panels at the optimal tilt angle of 45 degrees will produce around 6 148 kwh a year. In the uk south facing panels will generate more than other orientations. But west facing panels are able to generate more even flow of electricity. I do think over time with newer types of solar panels harvesting and new tech a person might be able at at least a third of solar engery by using wall mounted systems.
