PV Solar Panel System Cost in 2022: Pros and Cons of Solar Panels

Sunlight made into electricity. It’s that simple. Enough electricity to power not just a few appliances, but an entire home, including transportation in case of battery electric vehicles (BEV) or plug-in hybrids. That’s where we are quickly heading, but let’s deal with the basics of solar power for homes, first.

Solar and PV Encapsulated

PV stands for Photovoltaic. — The quantifiable process of converting sunlight (solar) into electrical power. For the conversion to be realized and useful, the right semiconducting material must be in place. — This results in efficiency that helps us put into perspective how solar energy can and does compare to historical methods of producing electrical power.

Solar cells are the fundamental, man-made part. Each cell produces about 1 to 2 watts of power. While that isn’t much, for the small size they are, it’s actually quite sufficient.

Group cells together into modules and stack modules into arrays, and suddenly kilowatts of electric power can be realized. To visualize what we are communicating, check out this short video from the U.S. Department of Energy.

For the solar cell to be effective and efficient, it must be properly housed and protected. Durable glass for its transparency is the obvious choice and results in the modules we call PV solar panels.

A module can be as small as those found on calculators, which date back to mid-20th century technology. Or modules can be arranged as solar arrays, which today is what we consider to be a solar panel system.

Contemporary solar cells are manufactured in about a half dozen ways. The ongoing and still most popular material is crystalline silicon. – Its relatively high efficiency in converting energy supplied by photons to electrical power is why it continues to be popular.

Monocrystalline vs. Polycrystalline Solar Panels

There are two main types of solar panels on the market today: monocrystalline and polycrystalline.

Monocrystalline panels provide anywhere from 17% to 22% solar energy-to-electricity conversion efficiency, while polycrystalline panels achieve between 13% and 16% conversion efficiency.

Thanks to their higher energy conversion efficiency, monocrystalline panels are more costly on a per watt basis than polycrystalline panels, but they do occupy less space on the rooftop.

If a rooftop span and size are limited, then it makes sense to pay a little extra for high-efficiency monocrystalline panels from manufacturers like SunPower, LG, and Panasonic.

2022 Metal Roof Cost Per Sq.Ft. – Metal Roof vs. Shingles Cost

Metal roofs are becoming increasingly popular with many savvy homeowners and it’s not hard to see why; compared to the more traditional approaches like asphalt shingles and cedar shingles and shakes, metal offers many important advantages including a significantly longer lifespan, low maintenance, excellent durability, and superior energy efficiency.

Cost:

On average, you can expect to pay between $9.50 to $17.50 per square foot to install a metal roofing system on a typical residential house. For example, an average-sized single-story house with a fairly simple roof shape measuring about 2,000 sq. ft. or 20 squares could cost anywhere from $19,000 to $35,000 for the installation of a high-end metal roofing system such as stamped metal shingles or tiles and standing seam metal roofs.

The Cost of a Standing Seam Metal Roof, Plus Pros & Cons 2022

Standing seam is the premier choice in residential metal roofing. It is also the most expensive; around two or three times the cost of corrugated metal panels and asphalt shingles, and about 10% to 20% more than metal shingles like interlocking steel and aluminum tiles and shakes.

Standing seam offers unbeatable value (through durability, longevity, energy-efficiency, and style) that is hard for any other roofing material to match. Let’s explore this in further detail:

Cost

The current national average cost to install a standing seam metal roof on a typical single-family house can range between $10.50 and $17.50 per square foot or $1,050 and $1,750 per square. This assumes a professional and warrantied installation of G-90 galvanized steel or Galvalume 26-gauge or 24-gauge (better) steel panels finished with the factory applied Kynar 500 paint finish. Aluminum panels finished with Kynar 500 paint are also an option and may cost slightly more than steel.
