The price you pay for solar depends on many factors:
The bigger your solar panel system, the pricier it will be. Importantly, the average per-unit price for solar decreases with increasing system size.
Like any product or appliance, solar panels come in varying quality which can be highly dependent on brand.
The type of panel you install (typically monocrystalline, polycrystalline, or thin-film) directly impacts the overall quality of your installation. Higher quality = higher prices.
The cost of a solar panel installation doesn’t just come from equipment. Your solar installer will also charge for the difficulty of the installation, meaning if you have a complex roof your system may cost more.
Solar companies all charge different labor rates for their work. You may opt to pay more for a more reputable company with better reviews and a shorter time period until installation.
While it’s not a large factor, paying for permits and your interconnection fee to the grid will add a little to the top of your total solar installation price.
Solar is a major purchase, and one that is often accompanied by significant complexity. With that in mind, most solar shoppers in the US compare two to five solar quotes before making a decision. Why? Comparing multiple solar quotes saves you money.
There are two primary reasons that comparing multiple solar quotes can save you money: competition and transparency. The competition effect means that each additional quote you receive for solar will help you to find the right solar panel system at the right price. Transparency can be trickier to put a price tag on, but for a market that has historically been opaque, knowing what equipment will be installed on your roof–and the quality of that equipment–helps to ensure you’re getting the best solar solution for your needs.
This is where EnergySage can help: we take the hard work out of finding, calling and trying to compare quotes from different installers, by gathering custom solar quotes from local installers on your behalf and putting them in an easy-to-compare, side-by side format. When you receive multiple solar quotes through EnergySage, the two of these components combine, allowing you to save 15 to 25 percent on the cost of solar compared to going solar outside of EnergySage.
