How Much are Solar Roof Panels

By Solar Energy Last updated Jan 14, 2022

Functionally, solar roof shingles resemble conventional solar panels in size, but are smaller than most solar panels: the average photovoltaic shingle is between 12 “and 86” tall and weighs about 13 lbs / sqm. The number of solar panels per shingle and how long it takes to power a house or building depends on the size of the building and your average energy consumption, but installing a few solar shingles can reduce your overall energy costs. Luma Solar Power Shingles has experienced several years of solar roof installations in more than 20 US states and promises a higher conversion efficiency of 21% higher than conventional rack solar panels. ^{Sources: 12}

Installation of solar panels has a number of costs that depend on a number of factors, including your condition, device brand, and personal energy consumption. In this article, we break down the cost of solar panels by size, state, and module brand which will affect your final solar panel costs. The average price of solar shingles for your roof can range from $15,000 to $20,000, but if you opt for a more sophisticated system like a Tesla solar shingle, it could cost you up to $70,000 or more. ^{Sources: 10, 12}

The cost of installing solar panels depends on how much electricity you want to produce and how large your system is. The larger the solar system you install in your home, the lower the cost per watt. Solar panels cost about $10 per kilowatt-hour (kW) of installation in the US, which is between $17,760 and $23,828 before the state tax credit, with the average price per watt of solar panels ranging from $2.40 to $3.22. ^{Sources: 2, 8, 10}

Solar panels are money you save on your electricity bill and earn back your original installation costs over 7 to 20 years. Solar leases allow homeowners to install solar panels without paying upfront, which can reduce the total cost of solar panels. Permission fees are included in the total cost of solar panels, as well as installation fees levied by contractors. ^{Sources: 2, 4}

Solar panels cost an average of one dollar per watt, which ranges from $2.50 to $6.00 per watt per module. The cost of installing 24 solar panels is $24 per solar panel to install and does not include any other system components and installation. On average, installation, approval and labour costs account for about 35 per cent of the price of installing solar panels. ^{Sources: 3, 4}

The cost of a single solar panel from $2.67 to $3.43 to buy and install is based on its capacity, measured in Watts [4]. The average size of a 5kW solar system is between $15,000 and $18,200 for installation, with larger systems costing more. ^{Sources: 3, 7}

The following table uses data from EnergySage, a solar marketplace that records the average cost of 6kW- and 10kW- solar module systems as well as the solar module brands used in installation projects. The solar module cost analysis for an entire residential complex is based on a 62 kW system with an average cost of $270 per watt. One way to save on the cost of solar panels is to install less expensive panels but there are other ways to save money without sacrificing quality. ^{Sources: 3, 5, 10}

The average national cost of installing solar panels on your house is between $15,000 and $21,000, but most homeowners pay somewhere between $18,000 and $60,000 for a grid-connected system installed on the roof in a sunny area. Ultimately, the cost of solar panels is less important than the return you get from installation. The costs are worthwhile if one considers the savings and advantages of channeling solar energy into one’s own home. ^{Sources: 3, 4, 10}

If, on the other hand, you need a new roof and want to switch to a solar system from Tesla, the costs are about the same as with a conventional solar system. Tesla recommends installing a $1,023 solar roof system that costs $3,901,753 after deducting the solar tax, assuming a moderate roof complexity. This means that the total cost of the new roof over a conventional solar system is $301,150.07. ^{Sources: 1}

A commercial solar power plant with an output of 10 kW (2 MW) would cost US $1.83 per watt after tax reductions and incentives. A 12.3 kW system equivalent to the solar panels mentioned above would end up costing $48,128. Installation costs for solar panels per kW are considered to be the average cost of work per watt, which is about $0.50, and the chart below reflects the average labor costs for different plant sizes. ^{Sources: 5, 9, 11}

The average cost of solar panels has decreased from $7.34 per watt in 2010 to $2.53 per watt in 2019. The price of solar panels is therefore low and the cost of solar panels makes up the bulk of what you pay to install solar panels in your home. The total installation cost is not just a look at the total cost to understand how the cost of a solar roof compares to the cost of solar panels. ^{Sources: 1, 2, 5}

Tesla’s solar roof website includes a price estimator that gives $42,500 as the total price for an average 2,000-square-foot home with 10kW solar panels. If Tesla’s online price calculator for solar roofs is correct, its new higher prices will be competitive with conventional solar panels, at least in the District of Columbia. ^{Sources: 0, 6}

Solar panels are not installed on the ground, but on the roof, which changes the installation and labor costs. Solar roof shingles and tiles also vary in price, and installing a roof with solar panels costs about half as much as installing solar roof tiles ($40,000 to $80,000). The installation of solar panels (the cost of installing a frame to house solar panels for your home) also has an impact on costs.

Luma Solar Power shingles stand out from other brands by positioning themselves as the only upgradable solar roof shingle system. They have experienced several years of solar roof installations in more than 20 US states and promise high conversion efficiency of up to 21% higher than conventional rack-mounted solar panels. According to the company, their patented shingle design allows air to flow through the shingle, and their small shingle profile ensures that they can be switched on and off throughout the day. ^{Sources: 4}

If you are trying to choose between installing solar shingles or traditional solar panels on your roof, there are a few benefits and cons to consider. Solar shingles are lightweight and easier to install than ordinary shingles and are designed to withstand rain, wind, and hail. ^{Sources: 2}

Solar shingles are a relatively new technology that is designed to look like normal asphalt shingles on the roof. Depending on the roof shingle brand, they produce between 1.3 and 6.3 watts of energy. ^{Sources: 2}

Solar roof shingles are similar in size in functional terms to conventional solar panels, but are smaller than most solar panels, with the average photovoltaic shingle measuring between 12 and 86 lbs/sqm. The number of solar panels per shingle and how long it takes to power a house or building depends on the size of the building and your average energy consumption, but installing fewer solar shingles will reduce your overall energy costs. In the vast majority of cases, say, 95% of roofs with solar panels do not need additional support. ^{Sources: 0, 4}

The solar panels and their shelves are fixed to the roof with the weight of a cinder block. An additional advantage of a ballast mounting system is that the panels are inclined to maximize production, which is not possible with other types of mounting and depends on the angle of the roof on which they are mounted. With EPDM rubber or TPO materials, the solar collectors can be mounted on your flat roof without penetration. ^{Sources: 0}

The premium over conventional solar panels makes them more expensive than a Tesla solar roof. An entire Tesla solar roof for the same house, provided it has a simple roof without any complexity, comes to $43,900. This is significantly higher than with a conventional solar system on the roof. ^{Sources: 3, 5}

The Tesla solar roof is a full-face replacement with glass tiles that look like normal roof tiles but contain solar cells and electronics. It makes no sense to install a solar roof if you love the look but are not ready to install conventional solar panels. It makes sense to install them only if the existing roofing material is too expensive and needs to be replaced by slate. ^{Sources: 3, 5}

He explained that the Tesla Solar Roof is a glass solar tile that, by hydrographic pressure, looks like slate or mud bricks instead of dark shingles. The glass layer includes slats that let the light from an angle onto the roof, but when you are at street level, the slats present themselves differently, as the printed design reveals. When you hear that, you realize that the roof is actually covered with solar panels. ^{Sources: 3}

Tesla is still working on the solar roof tiles of Tesla, designed to look like normal roof tiles installed on a house and serve as solar panels to generate electricity. The company has been tinkering with it for three years and recently announced that it has finally completed a test installation of two different iterations. ^{Sources: 1}

Tesla’s solar roof website includes a price estimator that gives $42,500 as the total price for an average 2,000-square-foot home with 10kW solar panels. If your home doesn’t need a roof replacement, conventional solar panels are cheaper as an option than solar shingles. A Tesla solar roof installer works with another solar installer or roof company so that no one has to put a solar roof on their house. ^{Sources: 1, 5}

Not to mention that while conventional solar panels are available, the installation process for solar shingles is much faster. Solar shingles come in the same colours as solar panels, which are blue and black. However, some traditional solar module plans offer more colour options than solar roof tiles. ^{Sources: 5, 8}

Conventional solar panels face the perfect intelligent inverter for the same task and size of the system. Compared to the cost per watt of a solar roof, conventional solar panels can be compared to an apple and a watermelon. As discussed above, solar shingles are more expensive than solar panels. Since solar roof tiles are new, they do not have many fitters. ^{Sources: 7, 8}

Although I am a big fan of Elon Musk, I am frankly less impressed with the progress he has made in making solar roofs a reality. The truth is that he is nowhere near able to do it in areas of the country where Spain’s most expensive tiled and slate roofs stand. If Tesla roofs were stacked in these areas, they would be 15 times more expensive than conventional shingle solar systems. ^{Sources: 7}

Insiders spoke to 14 Tesla Energy customers who had solar roofs with solar panels installed by Tesla. They said they were left in the dark for weeks, ghosted by their dedicated project consultant, sent into a dizzying circle of Tesla phone complaints and that the system had caused long delays and their roofs were not working. Insiders spoke to 14 customers of Tesla roofs and solar panels who said they were confused and sent through customer service circles.
