The cost of a home solar panel system is not just the cost of solar panels. The cost of a whole solar power system includes the cost of solar panels, inverters, batteries, wires, switches, licensing and documentation, transportation, and installation. Homeowners who plan on installing a solar energy system need to confirm with solar installer companies what they include in their solar quote.
The costs of home solar systems may greatly vary from state to state and even city to city. We discuss below what affects the cost of a solar panel system.
First of all, the climate of your region. Imagine two homeowners who need 10,000 kWh a year. One hails from Arizona, another from Alaska—or Washington. The cost they’ll incur to install a solar PV system that meets their demands will be different. In Arizona, the cost of such a solar panel system maybe around $14,000. But the system for generating 10,000 kWh annually will cost homeowners of Washington more. Why? The answer is, the climates of both areas are different. How many solar panels you need for your home depends on the amount of sunlight your area receives every year? One may need 22 panels; another 28. This is why the cost of a solar power system differs across the country.
Secondly, your roof. When a solar installer company calculates the cost of your solar panel system, they take your roof parameters into consideration. Is it south-facing? Is it flat or have a pitch? If it is flat, the racking may cost you more. Does it have any shade? These parameters affect the efficiency as well as the cost of installing home solar panels in Arizona.
Thirdly, the quality of solar panels, inverters, and batteries is another factor. There are hundreds of solar companies manufacturing, or importing solar panels and allied equipment. If your solar installer is offering unbelievably low prices, make sure that you do not compromise on the quality. Another factor when it comes to the cost of solar panels is how they are manufactured. There are different types of solar panels namely monocrystalline, polycrystalline, and thin-film solar panels. The monocrystalline panels have the highest efficiency and are expensive as compared to the other two.
Lastly, how much the companies charge for the installation of a solar panel system. Usually, big companies cost more since they have more needs as compared to small companies. Research carried out by Energy Sage shows installing solar panels through large companies may not be the best choice as you will have to pay comparatively more.
