Solar Panel Installation

To maximize your solar panel system’s energy production, your system should be installed where the panels will be exposed to the most sunlight. This is why rooftop home solar installations are so popular. If your roof isn’t suitable for solar panels, you can also install the panels on the ground.

In an ideal home solar installation, your home would have a large, sunny, east-facing roof with a 10° pitch. However, you don’t need ideal conditions to benefit from solar power. Solar panels can be installed on most roofs so you can save on your electricity costs and help the environment, too.

Is Solar Installation Suitable For Where You Live?

Even if you don’t live in a particularly sunny state, solar panels can still be a smart investment. The amount of money you save by going solar largely depends on your electricity rates regulated by EMA quarterly a year.

Is Your Roof Suitable For Solar Installation?

Solar panel systems can be installed on most roofs. To determine whether a roof is suitable for solar, solar installers will look at:

1. Direction of The Roof

East-facing roofs are ideal for solar because they get the most sunlight over the course of the day. However, a solar panel system on an south- or west-facing roof can still produce enough energy to reduce your electricity bills, save money and reduce your carbon footprint.

2. Pitch Angle of The Roof

Solar panels can be installed on roofs with a pitch between 10° and 20°. Even if your roof is flat, you can still go solar as long as you mount your panels at a good angle.

3. The Size and Shape of Your Roof

It’s easiest to install panels on a large square roof. A general rule of thumb is that for every kilowatt of panels you want to install, you will need about 100 square feet of roof space. A typical home system will require about 500 square feet of space to install solar panels.

Things like skylights, dormers, and chimneys will affect the amount of space available for a home solar installation. Generally, solar installers can design the layout of your panels around these obstructions in a way that maximizes your electricity production.

4. Shading On Your Roof

It is important that your roof gets enough sun throughout the day to maximize electricity production. Tall trees or buildings nearby can block the sun, cast shade on your roof, and reduce the amount of electricity your panels produce. You can trim trees so that more sun reaches your panels – doing so can actually have environmental benefits, though it might not seem that way.

5. Age of Your Roof

Solar panels can last for over 25 years, and removing them to replace your roof a few years after installation can be costly. Before you install your panels, make sure that your roof is in good shape and won't need to be replaced in the near future.

6. Materials of Your Roof

Solar panels are compatible with most roofing materials, including composite, wood, cement tile, slate, tar and gravel, or metal. While you can install solar on slate, cedar, and clay tile roofs, they are more prone to breakage during solar panel installation. Make sure that you work with an experienced installer if your roof is made of these materials.
