Does Going Solar Make Sense For Your Home?

Questions you need to ask yourself before going solar

Solar power is a great way to save money and use completely green energy, but to be perfectly honest, it's not right for everyone.  Solar power equipment and installation is costly.  Certain areas and home situations will not be ideal for generating power, and certain cities and states don't provide the same incentives, making it a tougher decision.  To clear up some of the questions and confusion, here are 5 questions to ask yourself to find out if solar power is right for you and your home.

  1. Are You Going To Be In Your Home For A Long Time?
    This is one of the first and most important questions to ask when considering solar power.  A solar power system can be quite costly ($10,000-$40,000 depending on the size and wattage), so just like when purchasing a home, you'll want to weigh your options carefully.  The average home will end up saving about $100-$200/month depending on the incentives and programs you qualify for, so you're looking at about 4 to as much as 30 years before the system pays for itself.  If you're unsure how long you'll be in your home, leasing your solar equipment will probably be your best option.
  2. Does Your State/City Make It Worth Your While?
    This is where you're going to have to do some research.  Some states (most notably California and Vermont) heavily incentivize the purchase, installation and use of solar panels to the extent that you'll not only save money, but you may actually generate income from your surplus power and from the sale of SRECs.  Other states have no such programs or even a certification program for SREC generation, making it much more costly for the same equipment.  Do your research, and make sure to find all of the city, state and federal programs you qualify for.
  3. Is Your Home In An Ideal Location?
    You can't make solar power without sunlight, so having a home with a small roof (a narrow house) or a home that is shaded by trees, hills or buildings will severely limit the amount of power you can generate.  You don't need a massive roof in direct sunlight for solar to make sense, but the better your situation, the more money you'll save over the life of the panels.
  4. Do You Have Large Energy Needs?
    Calculating your energy requirements can be tricky.  Most people do not power their homes 100% off of solar energy, but you want to get a good idea of how much you will need.  A typical solar power system will generate between 1000-2000 kWh per month.  To get a good idea of how much power this is, the best way would be to look at your electricity bill and see how much you're currently using.  Alternately, you could go through your home and add up the electrical appliances you actually need.  For example, a desktop computer will use around 300-500 watts, whereas a refrigerator will use 500-1000 watts.  How this converts to kWh is take your total wattage usage (for this example, let’s say it's just the computer and the fridge, so around 1200 watts) times the amount of time it's being used (again, let’s assume that they are both used 24 hours/day) and you get 28,800 watt hours (or 28.8 kWh).  There are also devices you can get to monitor your usage, or you can simply look at your meter and measure it from month to month or day to day.
  5. Is Going Green Important To You?
    Finally, how important is it that you "go green"?  For some, the cost, the hassle of applying for government programs and the potential to save little to no money depending on your situation may not matter when you take into consideration the positive impact you'll be having on the environment.  The green aspect of going solar is an intangible value that you'll need to think about and decide for yourself what its worth.  Ultimately, there will be some cost associated with either decision, so weigh all of the implications and options carefully before making your final decision.

    Components: The Solar Panel is Only the Beginning

    There's a lot to know when it comes to building and installing a solar power system.  The components that go into a system are like the parts on a car in that they all work together for the same ultimate goal, but the quality of each component can make a big difference in performance.

    Guide to Choosing the Right Solar Installer

    A solar power system is one of the biggest investments a homeowner will make, so it's important to make sure that everything is installed properly and built to last.  Components vary quite a bit in terms of electrical output, form factor and weight, but most panels will come with a 20-25 year warranty, making solar a long term investment, dependent on a strong foundation of a quality install. 

  • Why Professional Solar Installation Matters

    Why Professional Solar Installation Matters

    The age of the internet has also ushered in a new wave of DIY thinking.  Where in the past, information was a precious resource, today you can learn how to do just about anything with a couple strategic Google searches.   Just because you can learn how to do something, however, doesn't mean you should, and when it comes to installing a solar power system, or anything heavy you plan on putting on your roof, it's a good idea to always use the services of a professional installer.

    What to Expect From a Solar Site Installation Visit

    As you get a little closer to pulling the trigger on a solar power system, one of the final steps before actually purchasing a product is to have a professional installer come out to your home and do a site visit.  The purpose of this visit is to make sure your roof is appropriate for solar power, determine what kind and size of system you will need and then put together a quote that will show you the pricing and details of your new system.  While a good installer will walk you through this process, being a good consumer means having some solid information going into your site visit, so here’s a look at what you need to know before the installer arrives.

    About Solar Shingles

    Green energy is a growing trend that helps the environment and can save you a lot of money over time.  Nearly every neighborhood in America will have at least one or two homes with solar panels on the roof, but some homeowners will resist adopting solar power simply because of the look of the panels.  Furthermore, although your homeowners insurance will cover your solar panels, installing anything onto your roof can often void your roof's warranty, discouraging some would-be solar converts.  This is where solar shingles come into play, and this new spin on a well-established technology makes a lot of sense for any homeowner considering the switch to solar.
