Cost Overview of Tesla Solar Roof
Cost Considerations for Tesla Solar Roof
Installing a Tesla Solar Roof is generally more expensive than conventional solar panel setups. The overall cost can vary, especially if you are already in need of a roof replacement, which is a substantial expense on its own.
Budget-Friendly Solar Alternatives
For those prioritizing cost-effectiveness in solar energy adoption, the Tesla Solar Roof might not be the optimal choice. For example, a Tesla-provided estimate for a Dallas home equipped with 12.46 kilowatts of solar capacity and a Powerwall battery amounts to $168,400. In contrast, traditional solar panels with similar capacity and a Powerwall for the same home are estimated at $26,966.
Impact of Roof Complexity on Price
The complexity of your roof, including factors like steep slopes, multiple levels, and numerous obstructions, can also escalate the price of installation.
Breakdown of a Sample Estimate
A specific estimate details $176,600 for the solar components and $29,600 for the removal of the existing roof on a large, 8,313-square-foot property. Adding optional Powerwall batteries costs an additional $10,500 each. Post-tax credits from the federal government, the price includes a rebate of $48,800. The cost without batteries equates to about $12.87 per watt, though this could be influenced by the size of the roof, as other estimates have shown lower prices.
In Illinois, estimates for a Tesla Solar Roof without batteries fluctuate between $5.72 and $6.54 per watt, contingent upon the intricacy of the roof. Similarly, in Texas, the cost is estimated to range from $6.05 to $6.77 per watt. These figures surpass the 2021 national average for residential solar installations, which was $3 per watt for an 8-kilowatt system.
Influence of Roof Size on Price
The size of the roof has a significant impact on the cost. For a smaller roof in Illinois, measuring 1,594 square feet, the projected cost after the federal tax credit is estimated by Tesla to be between $54,000 and $58,148, or $3.78 to $4.05 per watt. Although this is nearer to the conventional solar panel costs, it remains higher, with Tesla’s solar panels estimated at $2.54 per watt after tax credit.
