Yes, installing solar panels on both sides of a roof is possible. Some solar installation companies have installations where panels are set up on multiple sides, sometimes even four or more.
A roof plane pointing directly West or East will experience only about a 13% power decrease compared to a South-facing one. North-facing panels drop just 25% of their power relative to those facing South.
In specific scenarios, an East/West orientation can even produce more than a South-facing setup.
Does The Orientation Of The Roof Affect The Efficiency Of Solar Panels?
The orientation of your roof determines how much sunlight the panels can capture, which directly affects their performance and the benefits you can reap from them.
Roofs that face south usually get the most sunlight, which helps make the panels work their best.
But if your roof faces east or west – you can still generate much energy.
While the energy production may not be as high as that of a south-facing roof, installing solar panels on roofs facing other directions can still yield significant benefits.
Are Shading Issues A Concern For Dual-Sided Solar Panel Installations?
Shading can impact the performance of solar panels, so it’s essential to assess for any shading issues before installing panels on both sides of the roof.
Tall buildings, trees, or objects nearby can create shadows that might lower the energy the panels can produce.
It’s crucial to evaluate your roof’s surroundings and ensure there aren’t any significant shading issues that could hinder the overall performance of the solar panel system.
Does Installing Solar Panels On Both Sides Of The Roof Come With Additional Expenses?
Installing solar panels on both sides of the roof might involve extra equipment and labour, which could result in slightly higher installation expenses.
The increased energy production potential of dual-sided installations can offset the initial investment.
By generating more electricity, you can save more on your energy bills and even earn credits for excess energy fed back into the grid.
Does The Electrical Wiring Suitable For Dual-Sided Solar Panel Installations?
The electrical wiring of the solar panel system must be designed correctly to handle the higher energy production of panels installed on both sides of the roof.
Having a professional electrician assess the wiring needs is important to guarantee the safe and proper functioning of the system.
They will ensure that the electrical components, such as inverters and wiring connections, can safely and efficiently handle the increased electricity flow.
What Are The Benefits Of Connecting Solar Panels In Parallel?
When you wire your solar panels in parallel, it allows you to increase the number of panels contributing to your energy production without surpassing the voltage restrictions of your inverter.
Moreover, parallel wiring can also help you stay within the current limits of your inverter, as inverters have set amperage thresholds that shouldn’t be exceeded.
By maintaining the voltage consistent and merely increasing the current, parallel wiring can efficiently scale up your solar panel system.
This allows you to expand the system’s capacity while ensuring it functions within the specified parameters of your inverter.
