Unfortunately, panels are not the only cost of residential solar energy. Installation costs (labor and mounting parts) can be as high as $ 10,000 on some roofs for residential power systems. Since you are spending a considerable amount of money, it is important to make an informed decision about who you trust to install your expensive panels.
Most of the time, you will buy your panels, any associated solar energy pieces, and their installation from a single company. This one-stop-shop has many advantages and disadvantages. The most obvious advantage is convenience. You can get everything in one stop. You can find the best solar panel companies through Infinityenergy.
Another advantage is the financing options available from such large purchase and installation companies. Most of the big solar companies offer very affordable financing if you have good credit. Also, many solar companies will discount the cost of installation if you also buy panels from them.
One big downside is the tendency to stop "shopping around" when you find a company that offers everything at once. Large solar companies also tend to charge more for panels and offer a discount for installation. It sounds like you are saving money, but if you look at the panels separately, you will find that they are often cheaper to buy alone. If you do this, your installation may end up at a high price.
What do you risk if you choose a high-risk installer? First of all, you risk damaging your roof. Mounting solar panels is an art, and without proper flashing and installation, water can enter your roof system through the mounting brackets. This can cause thousands of dollars in damages, damages that your homeowners insurance probably won't cover.
If you choose a panel installation company that is not insured, you can be held liable if a worker is injured. Also, if something goes wrong along the way (i.e. a roof leak or fallen panel), a fully insured company will pay for the damage your installation has caused to your home.
