FAQs

  • 1.What are the four main types of solar energy?
    Passive solar gain. Solar thermal (for heating) Concentrated solar power (for electricity) Solar Photovoltaics (electricity)
  • 2.Will solar energy save me money?
    Solar panels and solar panel systems will save you money and bring a return on your investment in no time. Rising property values, lowered utility costs, and the federal tax credit all ease the upfront costs of installing solar panels.
  • 3.How long does a solar panel last?
    Industry-standard life span is about 25 to 30 years.
  • 4.What happens to solar panels after 25 years?
    In reality, solar panels can last quite a bit longer than that: the warranty typically guarantees panels will work above 80% of their rated efficiency after 25 years. A study by NREL shows that the majority of panels still produce energy after 25 years, albeit at slightly reduced output.
  • 5.Do solar panels damage my roof?
    As long as your solar panels are properly installed, they won’t do damage to the exterior or the infrastructure of your roof.
    If you are working with a qualified professional and your roof is in good condition, your solar panels won’t affect the integrity of your roof.
    Think.Solar is a qualified licensed company and provides a 10-year workmanship guarantee.
  • 6.What is the maintenance cost of solar panels?
    The average cost for routine solar panel maintenance is between $140 and $180, but warranties cover the expense of many services. The service you’re most likely to need is an annual inspection, which costs $150 on average across the nation.
  • 7.How Many Solar Panels Are Needed to Power My Home?
    The average home in the U.S. uses 10,400 kWh of electricity per year. If you install the average 250-watt solar panel, you’d need around 28-34 solar panels to generate enough energy to power your entire home.
  • 8.Does solar increase home value?
    Installing solar panels in a home not only helps to reduce current monthly utility bills but can also potentially increase the home’s value by up to 4.1% more than comparable homes with no solar panels.
  • 9.Can you walk on roof solar panels?
    Solar panels are not designed to be walked on. Walking on them can cause the glass surface to break and damage the cells beneath, reducing the efficiency of your system.
  • 10.Will solar panels reduce my electric bill?
    The number one reason to install solar panels is to help save on your energy bill in a sustainable way. While they may be costly to set up in the first place, you’ll eventually break even thanks to reduced energy bills – and you’ll make money on all the solar energy you don’t use, by selling it back to the grid.
  • 11.How much do solar panels save per month?
    Typically, a residential solar setup produces anywhere from 350-850 kilowatt-hours (kWh) per month. The average home uses approximately 909 kWh of energy per month (according to U.S. Energy Information Administrations), so owning solar can save you upwards of 90% on your monthly electric bills.
  • 12.Is solar energy expensive or inexpensive?
    The report follows the International Energy Agency’s (IEA) conclusion in its World Energy Outlook 2020 that solar power is now the cheapest electricity in history. The technology is cheaper than coal and gas in most major countries, the outlook found.
