Tesla Solar Roof Shingles vs. Traditional Solar Panels: What You Need to Know

Tesla has become a household name in many parts of the world, and you have probably read or heard about their solar roof shingles. They can be described as miniature photovoltaic panels that look more like the traditional asphalt shingles, and many homeowners prefer this look.

If you’re trying to decide between a Tesla solar roof and a traditional solar panel system, this buying guide will help you compare both options.

First, there is a very important difference between solar roof shingles and conventional solar panels.

  • Solar roof shingles are the combination of two products. They serve as a roof for your home, but they also generate electricity.
  • Solar panels are separate components that are installed on top of your roof, using the right type of racking system.

This difference has a very important implication for homeowners. Solar panels can be installed on almost any roof, as long as the structure is capable of carrying their weight. However, you replace your existing roof completely when using Tesla solar shingles, and this makes the project more expensive.

Based on upfront costs and return on investment, traditional solar panels are the recommended option for most homeowners. However, a Tesla solar roof can make sense financially if you’re planning to build a new home with solar panels, since you haven’t spent on a roof yet and you have the chance to combine two building elements.

Solar roof shingles are also viable economically if you have an old roof that will need replacement soon. Just keep in mind that delivery times can be long, due to the growing popularity of Tesla products in general.

Of course, personal preference is also important when deciding between different products. Installing a Tesla solar roof is a great option if you don’t like the appearance of solar panels, or if you’re loyal to the brand and prefer their products. However, keep in mind that Tesla also installs traditional solar panels as an alternative to solar tiles, and their price tag is much lower.

Cost per Watt

The national average residential solar cost per watt installed is $3.10 for a typical 5kW (approximately $15,500) to 7kW (approximately $21,700) PV solar panels system when installed by local installers, before the 26% solar investment tax credits from the federal government.

Did you know? The 26% solar tax credits have recently been extended by congress through the end of 2022. Notably, solar ITC apply to the full amount paid for the installation of a new solar panels system.

Depending on the state you live in, your quoted cost per watt can range from $2.78 to $3.40, on average, when installed by a (small) local solar panel installer, before the 26% federal tax rebate.

Note that solar investment tax credits (ITC) are being phased out, gradually, with the amount of tax credits decreasing from 26% to 22% in 2023 (the final year for solar ITC).

How Solar Pricing Has Decreased Over Time In 2008, the cost of a solar power installation was $8.82 per watt.

Average System Cost for residential PV Solar Panels installed by Local Installers:

Small Home Average Home Large Home
Home Size 1 – 2 bedrooms 3 – 4 bedrooms 5 bedrooms
System Size 5 – 7kW 7 – 8.5kW 9 – 10kW
System Cost $15,300 to $21,420 $21,420 to $26,010 $27,540 to $30,600

Federal Solar Investment Tax Credits – All You Need to Know in 2022!

Federal tax credits for the installation of solar power equipment remain in effect, and there is significant money to be saved.

This guide to the Federal solar investment tax credits gives you what, how, and how much can be saved when you install solar electric panels or BiPV solar tiles aka solar photovoltaics or a solar hot water system on your residence. Saving money at tax time has never been easier – and this is a very good time to consider going solar.

What is the Federal Solar Investment Tax Credit?

Since Congress passed the Energy Policy Act of 2005, the Residential Renewable Energy Tax Credit has allowed homeowners to deduct a percentage of the installed cost of a solar PV system for their home. It was originally set to expire after 2007 but has since been extended several times. The current expiration date is December 31, 2023. Will it be extended again? Probably, but it’s a risk to wait.
