What are the Important Aspects to Consider during Rooftop Solar Panel Installation?
Here are a few factors to consider when determining whether your home is appropriate for rooftop solar panels.
1. Size and Shape
The roof size determines the number of panels that can be accommodated. For every kilowatt of power, you aim to generate, you’ll typically need about 100 square feet of roof space. In most cases, 500 square feet of area is required to install enough rooftop solar panels to provide adequate power for a home. If your roof contains fittings such as skylights or chimneys, you can request that your solar power provider build a configuration that addresses these obstacles.

2. Roof Orientation
South-facing rooftops are ideal for solar power since they receive the most sunlight on any given day. Homes with east-facing or west-facing roofs, on the other hand, will still be able to create enough energy while also lowering your energy bills.
3. Pitch Angle
The angle of your roof plays a role in solar energy collection. Solar panels are easiest to put on roofs with a pitch angle of 15 to 40 degrees. If your roof is flat, mounting systems are available that allow you to modify the angle of your rooftop solar panels.
Photovoltaic panels require direct sunlight to generate energy, so while installing solar panels on the roof it makes sense to remove any shade that may reduce or interfere with sunlight. The majority of the time, the shade comes from neighboring trees or tall structures.
If the shade is produced by a tree, you can have it trimmed so that more sunlight can reach your panels, or you can simply relocate your panels. If a huge building throws a shadow on your roof, ground-mounted panels in a less-obstructed region may be preferable to rooftop solar panels.
5. Age and Condition of the Roof
Although solar panels aren’t particularly heavy, it’s still a good idea to make sure your roof is stable enough to hold them. Considering that solar panels can last up to 25 years, it’s worth checking to see if your roof will need to be repaired or replaced, as reinstallation prices can be rather high.
6. Material for the Roof
Solar panels are generally compatible with the majority of common roofing materials—but they have particular difficulty being installed on slate, cedar, and clay tile roofs. Installing panels on these materials is more difficult because they are prone to damage during installation, but it is not impossible.
With these considerations in mind, you can effectively harness solar energy, reduce your carbon footprint, and even connect your residential solar system to the grid and sell electricity through net metering if you have enough power.
