Leading solar panel manufacturers such as GAF Energy have consistently produced innovative solar kits which have breathed a new life into the roofing industry. Today’s solar panels are designed to save homeowners money on energy bills without negating the aesthetics of their homes. If you’re like many homeowners, you’ll want to know how much solar roof panels cost and whether it’s a worthwhile investment for your North Port, FL home.
What Materials Makeup Solar Panels
Nowadays, solar panels are primarily made of photovoltaic cells. Typically, photovoltaic cells are mass-produced and accurately cut by lasers and assembled in a glass panel. So, instead of laying emphasis on the weight, solar panel manufacturers today put an emphasis on strength and durability. In place of the traditional lightweight encapsulate, durable glass is used to cover the panels to help withstand the elements.
In terms of the cell composition, solar panels can either be Thin-Film Solar Panels or Crystalline Silicon Solar Panels.
The most common option is crystalline silicon (c-Si) solar panel which looks like black or blue rectangular grids with smaller squares. Those tiny squares are actually silicon solar cells, and all the cells link together in a series to form a complete electrical circuit.
Thin-film panels are mostly used in large utility-scale installations. Typically, a thin semiconductor is deposited on glass, metal foil substrate, or plastic, creating a very thin and sometimes flexible product. Its lightweight and flexibility make it suited for curved roofs, RVs, and other unique installations.
Different Sizes of Solar Panels
Traditional solar panels are availed in two common configurations: 60-cell and 72-cell. The standard dimensions for these options are 39″ x 66″ (3.25 feet x 5.5 feet) and 39″ x 77″ (3.25 feet x 6.42 feet) respectively.
These are the standard sizes for solar panels for most residential and commercial buildings, give or take an inch on each side. Additionally, you need to consider the variations resulting from the different frame sizes used by different manufacturers. There are other solar panel size configurations available on the market, but they are much less common. For instance, Panasonic offers 96-cell panels measuring 41.5” x 62.6”.
In terms of the space coverage on your roof, you need to estimate your average energy consumption to determine whether your roof will adequately take up the required number of panels. The average American household utilizes 867 kWh of electricity each month. That means that it would take a 6.5 kW solar array to offset your usage.
In total, an average-sized solar system would take up 375 – 429 square feet of space on your roof. This means solar systems can be comfortably mounted on most residential roofs, but the exact size will depend on the panel wattage as well as your roof’s layout.
The Cost of Solar Roof Panels
There are a few factors influencing exactly how much you’ll spend to install solar roof panels on your home. They include:
- Your home’s average annual utility cost and energy usage
- Your rooftop’s solar potential, which is the amount of sun it receives annually
- The average local cost for solar panels in your area
- The average labor cost and demand for solar panels in your area
- Local and federal incentives and rebates you could receive
The Department of Energy expects the cost of solar panels to continue reducing over the next couple of years as millions of homeowners embrace the idea of green energy across the country. The average cost per watt typically ranges between $2.57 and $3.35.
The most important thing is to know the average cost per watt since not every home consumes the same amount of electricity. It all depends on how much electricity you wish to generate even if it doesn’t fully offset your monthly consumption from the grid.
