Is My House Good for Solar?

There is no doubt that solar energy is the way of the future. As we look to move away from non-renewable energy sources, it's more important than ever to find ways to supply power in a way that doesn't harm the environment. Solar energy is an elegant solution, particularly for the needs of everyday homeowners. As solar panels become increasingly more ubiquitous throughout California, you might be asking yourself, "is my house good for solar panels?", and whether or not it's time to make the switch.

Many homeowners are deterred by solar because they don't have all the information, and they may even be deterred by common myths and misconceptions. But solar isn't complicated, and we're here to help. There are many factors to consider if you're interested in solar, and chief among them is the viability of your home. Some homes are better equipped than others for solar power.

Key Factors to Consider

How Much Sunlight Does Your Home Get?

The most fundamental question for solar viability is sunlight exposure. Solar panels need direct sunlight to generate electricity efficiently. Consider:

• How many hours of direct sunlight does your roof receive daily?
• Are there significant obstructions blocking the sun?
• What direction does your roof face?

South-facing roofs in the Northern Hemisphere typically receive the most sunlight throughout the day, making them ideal for solar installation. However, east and west-facing roofs can also work well.

What About Shade?

Shade is one of the biggest factors that can impact solar panel efficiency. Common sources of shade include:

• Trees
• Neighboring buildings
• Mountains or hills
• Chimneys or other roof structures

Some shade issues can be mitigated. For example, you could cut down a massive tree that constantly obscures your home. But if you're situated next to tall buildings that conveniently block the sun in most directions during most of the day, or if there's a huge mountain or cliffs right behind your house, there's not much you can do.

If your house is in a shady spot, we urge you to consult with the professionals before you make a decision. Sunlight and shade doesn't seem complicated, but how much sun actually hits your roof in a beneficial way is trickier to gauge. You shouldn't assume that solar panels are out of the question, but it will likely require some out-of-the-box thinking on the part of your solar installation company.

How Is Your Roof Sloped?

The slope (or pitch) of your roof affects how efficiently solar panels can capture sunlight. While solar panels can be installed on most roof types:

• Moderate slopes (15-40 degrees) are generally ideal
• Flat roofs can work with mounted racking systems
• Very steep roofs may require specialized mounting

What Condition Is Your Roof In?

Before installing solar panels, it's important to assess your roof's condition:

• How old is your roof?
• Are there any existing damage or leaks?
• What material is your roof made of?

If your roof needs replacement in the next few years, it's often better to replace it before installing solar panels. This avoids the cost of removing and reinstalling panels later.

What's Your Roof Made Of?

Solar panels can be installed on most roofing materials, including:

• Asphalt shingles (most common)
• Metal roofing
• Tile (requires special mounting)
• Flat/built-up roofing

Some materials are easier and less expensive to work with than others. Tile roofs, for example, require more careful installation to avoid cracking.

How Big Is Your Roof?

The available roof space determines how many panels you can install and therefore how much energy you can generate. Consider:

• Total roof area
• Usable space (excluding vents, skylights, chimneys)
• Multiple roof sections if one isn't large enough

The Bottom Line

Most homes in California are excellent candidates for solar power. Even homes with some challenges can often benefit from creative solutions. The best way to know for sure is to get a professional assessment.
