How Solar Panel Installation Works

Solar installation is a straightforward process. Your solar company will handle most, if not all, steps. A representative will begin by holding a consultation to assess your energy needs and home design. Theyll then create a system based on your homes specifications and handle required permits from your local municipality. Finally, they will install the system and conduct final inspections. This process can take up to 60 days to complete.

    Are Solar Panels Worth The Investment

    Thanks to the lower-than-ever cost of solar panels and various solar incentives, solar panels are a cost-effective investment for the majority of homeowners that will provide an excellent return on investment.

    Not only do they lower your energy bills, but you also get to power your home with clean renewable energy and reduce your dependence on your local utility company.

    Even though spending up to $20,000 is daunting, federal incentives eliminate 30% of solar system costs after 1 year. There are also various ways to finance a solar system – from solar loans and leases to PPAs – so you can pick whichever option that works best for you.

    Plus, solar panels provide significant utility bill savings in most areas. An average home solar panel system can save between $1,000 and $1,600 per year on electricity bills depending on the states net metering policy and the homes energy consumption.

    Actual solar savings will depend on the system size, the cost of electricity, home energy usage, and what net metering policies are in place, but the average solar homeowner can expect their solar payback period to be between 8 and 11 years. After that, theyll be enjoying completely free solar electricity for at least 15 more years!

    If youre still not convinced, you can use our solar panel calculator to find out how much solar costs and can save you for your specific home based on your average electric usage and prices in your area.

    Exclusion Zones And You

    Home Improvements the Clean Energy Way

    If an installer uses SunLock, Radiant or other high quality roof mounting systems you can be very confident they are motivated to do good quality installations. Someone using SunLock isnt suddenly likely to get lazy and forget about its exclusion zone and someone using Radiant is likely to leave at least 20cm between panels and roof edges anyway as that is good practice. A possible exception to this is if a less conscientious installer is only using a high quality mounting system because the customer requested it.

    If you are concerned about exclusion zones then it is best to bring it up with your installer before they put a system on your roof. You can check if an exclusion zone is required and if not, how much space from roof edges they are going to leave anyway. Note that if you push for as much solar panel capacity on your roof as possible, you may end up with panels that are closer to roof edges than is ideal. The customer isnt always right, but they often get what they ask for anyway.

    Adjustable Solar Panel Mount

    An adjustable or tilt solar panel mount costs between $200 and $500. This is the mount type you need for a flat roof. It is mostly used in commercial settings, but if you have a residential home with a flat roof, you could also use this method. The rack is adjustable, so you can precisely catch the perfect angle of the sun. Since not all flat roofs are completely flat, the adjustable tilting feature allows you to get a better fit no matter what your slope is. Most have a range where they are adjustable and where they cannot go past.

    How To Calculate The Solar Potential Of Your Roof

    There are a few rules of thumb you can follow that can offer a general idea of how much roof space is needed for solar panel installation. These guidelines can also help determine how much roof space you have available to put solar panels on.

    Generally, every square foot of roof space has the potential to generate about 15 watts of solar energy. Thus, a solar panel installation on a small home might only need around 200 square feet of roof space, while a larger home can require more than 1,000 square feet of roof space to properly offset electricity usage.

    To offset an average amount of energy usage by the average American home, youll typically need around 18 to 24 panels to be effective. That is, of course, if everything about those panels is ideal, where the positioning is optimal, the panels are of a standard rating, and the location gets adequate sunlight year-round. If you change any of those variables, the number of panels you need is going to change as well.

    If you want to get a sense of how many panels a roof can support, you don’t need a fancy solar panel square footage calculator. Heres an easy calculation you can do: Multiply the square footage of your roof by .75 to account for the required solar setback. Take that number, and divide it by 17.5, which is the average square footage of the standard solar panel size. The resulting number is the maximum number of solar panels you can fit on your homes roof.

    How Old Your Roof Is

    It isnt a good idea to mount solar panels on old roofs. You will end up paying additional funds to your roofing contractor to remove panels before installing a new roof.

    Besides, roofs undergo rapid deterioration as they age. So your old roof risks crumbling down if you add the additional solar panel weight.

    Most roofs survive for about 20 years. Notable signs of aging include:

    • Curling shingles
    • Excessive growth on the roof
    • Streaks and decolorization

    Never install PV panels on roofs that are more than 15 years old.

    Panels have a 2530-year lifespan and will likely outlive any older roof. Installing a new roof before putting solar panels on your roof is ideal.

    Solar Rebates Incentives And Tax Credits

    In states that have a solar sales tax exemption, the purchase of solar panels may be shielded from sales tax. Currently, at least 25 states offer a solar sales tax exemption and 36 states offer solar property tax incentives. By using our solar calculator quiz, you can check the incentives that are available for you!

    How The Installation Process Works

    The solar installation process is quite simple. The process might be different for other solar installers but for us there are four basic steps involved:

    1. Free Appraisal after a quick phone call and some number crunching, you will be provided a very high-level ballpark estimate remotely, based off satellite imagery in the area.

    We ask that you provide your address, and kWh consumption as well as some general information on your goals and what you hope to achieve and when you hope to achieve it.

    Those last two points are extremely important to us everyone has different goals and we want to really make sure we are taking care of your exact needs.

    Although estimates can be given remotely,visiting the site is prudent prior to installation. During a site appraisal, your existing electrical infrastructure will be inspected noting any upgrades that may be required. Similarly, your trusses and/or shingles may be inspected to ensure that a solar power system is viable on your home.

    If your trusses, membranes or general structure are not in perfect condition, a Professional Engineer will be called to verify the structural integrity of the building.

    2. Proposal we will then draw up a detailed proposal for you.

    3. Construction Most solar panel installations can be completed in just one to two days.
