Solar panels can reduce your electricity bills, lessen your environmental impact, and even boost your home's value. It’s no surprise they’re so popular. But you’ll first need to understand the sum you'd spend to install solar panels on your roof. This is where our team at Built to Last Roofing can help.

Let's look through the key factors influencing the cost of solar panels so you can make an informed decision about your solar investment.

Average Solar Panels Cost to Install per Watt in Texas

The average cost of solar panel installation on a residential roof in Texas is between $2.50 and $4.00 per watt. A small commercial building with a simple roof design and moderate energy needs might see a cost starting in the $2 to $4 per watt range.

For example, a typical solar system, enough to power a modest home, can cost between $15,000 and $24,000. If we talk about commercial buildings, then a cost starts in the $50,000 to $100,000 range.

Keep in mind that this is a rough estimate, and you’ll want to consult with a qualified solar installer for an accurate cost assessment.

Average Solar Panels Cost to Install per Square Foot in Texas

While the cost of solar panels is often quoted per watt, it can be helpful to consider the cost per square foot for budgeting and comparison purposes.

In Texas, the average cost of installing solar panels on a residential roof can range from $20 to $50 per square foot.

For instance, a small 100-square-foot system could cost between $2,000 and $5,000, while a larger 500-square-foot system could range from $10,000 to $25,000.

But remember, the price can change because of different factors that we’ll discuss below.

8 Key Factors Affecting Solar Panel Costs

Here are several factors that contribute to the overall cost of solar panels installation on your roof.

Let's explore these key elements in more detail:

#1. Roof Size

A larger roof can accommodate a larger solar panel system, which may potentially require more panels and increase the overall cost. However, it also allows for greater energy production, potentially offsetting the higher upfront investment.

#2. Roof Condition

A well-maintained roof is necessary for solar panel installation, as it needs to be structurally sound and leak-proof to ensure a long-lasting and efficient system. If repairs or replacements are needed, these costs will be added to your overall solar project, so you’ll need to get a professional roof inspection before you move forward.

#3. System Size

The primary factor influencing solar panel cost is the size of the system you need. This is directly tied to your home's energy consumption. The more energy you use, the more panels you'll need, resulting in a higher overall cost.

#4. Solar Panel Type

There are three primary types of solar panels, each with its own cost and efficiency.

#5. Installation Costs

Labor rates vary by region and the complexity of the installation. Our team has provided an approximate comparison of professional and your own labor costs.

#6. Solar Equipment

Solar panel cost is only part of the equation. You'll also need inverters, mounting equipment, and wiring to create a complete solar panel system.

#7. Incentives & Rebates

Federal and state incentives, such as the federal solar tax credit and local rebates, can significantly reduce your overall cost.

#8. Weather Conditions

Extreme weather conditions, such as heavy snowfall, strong winds, or hail, can potentially increase installation costs and affect the longevity of your solar system. Areas with harsh weather may need more robust mounting systems and panels designed for those conditions.

Calculating the Cost of Your Solar Panel System

To estimate the cost of your roof with the solar panel system, you'll need to determine your energy needs and calculate the size of the system required to meet those needs.

Here are some helpful steps to keep in mind:

Let’s look at the example:

You need a 6 kW solar system. You choose polycrystalline panels, which cost $3 per watt.

Total Cost = (Panel Cost per Watt * System Size in Watts) + Installation Cost + Equipment Cost - Incentives = (3.50 * 6000) + (3 * 6000) + 2000 - 6300 = $29,700

Note: This is a simplified example with the average prices. Actual costs can vary.

Solar Panel Roof Payback: Understanding the Benefits

The payback period for your solar investment is the amount of time it takes to recoup the initial installation cost through energy savings. The shorter the payback period, the more financially attractive your solar installation is.

There are several factors influencing the payback period, including:
