9 ways your solar installation can get more expensive

Empty Pockets Solar Costs

Most solar installers will charge by the watt capacity of your system. This will run you about $4,000/kilowatt, plus or minus a grand or so depending on where you live. So, for a “5 kW” system (which is the number everyone always throws around) you are talking about $20,000. That’s BEFORE incentives, however. To make it confusing, every state has a different solar policies and programs for home solar (which they shouldn’t). You need to learn what the specific solar incentives are in your state to really know what your final (net) price is going to be. But hey, that’s what we’re here for!

Here are 9 things you should be aware of which may inflate your cost of going solar:

1. Flat Roof Tilting. If your roof is flat, you must build some scaffolding to tilt it up towards the sun. That framework costs some money.

2. Different Roof Types. Some are harder to seal or flash, or find studs. Accordingly, some installers will charge more based on your roofing material. see more here

3. Distance. If you reside outside the regular service area of your nearest installer, there may be associated travel fees that will be passed on to you.

4. Monitoring Systems. Some solar companies sell monitoring systems which upload data about your solar energy production to the web. If these interest you, expect to pay a little more.

5. Trenching. Does conduit need to be run underground to near your meter? There may be a fee for that. This type of activity is generally associated with ground mounted systems… which brings us to….

6. Ground Mounts. If your system is installed in your backyard instead of on your roof, not only does your contractor have to build the framework but also secure it to the ground. That usually means concrete. Concrete, building a frame, and securing it to the ground costs money. Therefore, this type of installation is usually more expensive than installing a system on your roof. The upside? You get to aim and tilt the panels optimally for your region, whereas on a roof you are bound by the direction your home is already pointed.

7. Permits. Your region may have much trickier or more expensive building permits than the installer is used to. Therefore, you can expect higher fees for this.

8. Inverter Upgrade. Let’s say you want to install more solar down the road. Therefore, you could opt to purchase a beefier inverter to accommodate your planned upgrade for some extra money. For example, you might want to take advantage of utilities being required to pay for excess yearly production sometime in the near future. Currently they are not required to.

9. Service Upgrade. The inverter (the thing that makes the unusable DC current your solar panels produce into usable AC current for your home appliances) is like an appliance itself. It will need to be connected in your main breaker panel and there may not be space for it. This can create an issue and an electrician may need to install a sub panel, or your utility may need to upgrade your service (for example, from 100 to 200 amp service). You can tell what service you have by looking at the door to your main breaker panel, it should say (MAX AC) somewhere.

Now the fun stuff: DISCOUNTS!

  • Employee Discounts. Aside from the state rebates, you may qualify employee discounts. For instance, if you work for HP, Google, or SunPower, you get a discount. Check with your employer!
  • Group Purchase discounts. This is where many people get solar at once. Solar companies are going to start exploring this business model soon, but for now you can do it yourself if you have friends that are interested. If you call up an installer and have five serious customers in the same neighborhood, you can seriously lower overhead for the installer, and they can pass those savings on to you. Approach the installer about it.

Bottom line – don’t freak out about all this. The salespeople for your local solar company know their stuff and can explain all of it to you in better detail.

    Hello, I got solar system at home, but after I turned on, I started having problems with blinking lights, the power back and forth, my main panel making a noise and when I took a look sparks behind the circuit breakers. the electrician told me that when you get solar system, the company needs to replace your main panel and because they didn’t the bus got burned on two circuity breakers, the main and the AC. Anybody know if this is true or happened before? I will really appreciate it since it is going to cost me $2,500.00 plus involving insurance. Thanks

    How do I find out if i live near a company who installs and provides services I need to have a solar system put in? Do we need electric company to do anything? We live in Ward Co, ND.

    i am thinking about a new construction home in cochise co. we intend to use rastra wall sys. for the home and roof ie. flat, if we use staggered roof height would this give the angle needed for solar panels to be installed.

    1. Mike,

      The ideal angle is 30 degrees, but that’s ideal. The main thing is having minimal (no shade) and the array pointing South, West, or South East. No system is perfect. If you don’t have ideal conditions, solar still works, but it means that you’ll have to have more panels. The same house with ideal conditions would have less panels. Solar racking and framing can adjust your panels to the right angle, but it may not look pretty. Best to get an experienced installer to help you make the best of it. Hope that helps.
