Unfortunately, panels aren't the only cost of residential solar power. Installation (labor and mounting parts) costs can run as high as $10,000 on some roofs for residential power systems. Since you're spending a sizable amount of money, it's important to make an informed decision about who you trust to install your expensive panels.
Most of the time, you'll purchase your panels, any associated solar power parts, and your installation from one company. This one-stop shopping has many advantages and disadvantages.
The most obvious advantage is convenience. You can get everything at one stop. Another advantage is the financing options available from such large purchase and installation companies. Most large solar companies offer very affordable financing if you have good credit. Also, many solar companies will discount the cost of installation if you buy panels from them as well.
A big disadvantage 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 appears you're saving money, but if you look at panels separately you'll find that many times they're cheaper to buy on their own. If you do this, your installation may end up having a large price tag. When all is said and done, the average residential solar power system will cost between $25,000 to $40,000 dollars.
As a shopper, your first concern about your solar panel installation company should be quality. Installation is effective and safe, IF everything is installed carefully and correctly. Furthermore, anyone who offers installation should be 100% bonded and insured. The company should have a permanent installation staff as well, NOT a group of temporary workers they taught to install panels.
What do you risk if you choose a sub-prime installer? First of all, you risk damage to your roof. Mounting solar panels is an art, and without proper flashing and installation, water can creep into your roofing system through the mounting brackets. This can cause thousands of dollars in damage-damage your homeowner's insurance probably won't cover. If you choose a panel installation company that's not insured, you can be held liable if a worker injures themselves. Plus, if something goes wrong down the road (i.e. a roof leak or a fallen panel), a fully insured company will pay for damages their installation caused to your home.
Your second concern will obviously be the cost of installation. An old adage that holds true today is: you get what you pay for. If you choose the cheapest company, you may not get everything you're promised, or the installation will be sub-standard. Look for a company that has a fair amount of experience (10 years or more), and is willing to show you past projects they've completed. A truly responsible company will even let you talk to previous clients.
Installation is the biggest part of your solar power system. During installation, a lot can go wrong and set your panels up for failure. Carefully research your installation company options to make sure your investment isn't wasted on a poor installation.
