Solar Panels – Is there a difference?
With so many companies making solar panels it might seem hard to determine just what the best is. One way for Sacramento solar customers to determine which to choose is how many watts per square foot of panel area are produced. Solar panels have been typically 39” x 65” or 17.6 square feet and produce 250 watts, the better ones producing 345 watts for residential systems. The more output of the panels, the fewer of them you need and will allow the ability to add more in the future for an Electric Vehicle or a swimming pool. Another check point is where they are made and how long the panels have been in use; most companies are less than 5 years old with some being over 25 years in production. Warranties are a great way of telling how a company supports their product.
