Installing solar power for Homes

Ensuring your home solar electric or photovoltaic (PV) system is sized, sited, installed, and maintained properly is really important for making the most of its power performance. When installing a PV system, consider:

  • How big the machine should be to fulfill your electricity needs
  • Where in actuality the system are located and just how much room it requires (system siting)
  • Whether you prefer your system become attached to the grid or perhaps not
  • What should be done to ensure that the device is safe.

Therefore, it's best to have a professional solar power contractor install the machine. Whenever choosing a contractor, ask yourself here concerns:

  • Has the company installed grid-connected PV systems? Or even, has it installed grid-independent (or stand-alone) PV methods? Expertise in setting up grid-connected systems is valuable because some elements of the installation - specifically interconnection aided by the local utility—are unique to these methods. But a reliable organization with off-grid PV experience should not be eliminated simply because it offers not yet installed grid-connected PV systems. Experience with off-grid methods is important too, because grid-independent systems are more technically complex than grid-tied systems.
  • Just how many many years of experience does the business have actually putting in PV systems? a contractor who has been in operation quite a while most likely knows how to work with clients and to compete effortlessly with other businesses. Also, he or she will probably be conscious of the latest rule and allowing issues surrounding the installation of PV methods.
  • Is the company precisely licensed or certified? PV systems should really be set up by an appropriately certified specialist. This means that either the installer or a subcontractor features an electrical contractor's permit. A state electric board can let you know whether a contractor features a valid electrician's license.
    Neighborhood building departments may additionally need your installer have actually a broad specialist's license. Phone the city or county in your geographical area for additional information on certification.
    a solar rebate program may require that, not only is it precisely accredited, contractors must demonstrate that they have unique knowledge about installing PV systems. Special knowledge may be demonstrated through certification by solar industry and/or trade associations.
  • Does the business have pending or active judgments or liens against it? As with every project that needs a contractor, research is advised. Your state electric board can inform you of any judgments or grievances against a state-licensed electrician. Consumers should phone the city and county where they live for information about how to gauge technicians. The greater Business Bureau is yet another source of information.

It is always a smart idea to get more than one quote the installing your PV system. Be sure that all bids are created on a single foundation. For example, a bid for something mounted on the ground is normally very different from another quote for a rooftop system.
