FAQ

Frequently Asked Questions

1. What are the major components of a solar electric system? (PV)
• PV Modules: Photovoltaic modules
  to convert light energy into DC electricity.
• Inverters: Converts DC electricity
  into household power.
2. How long is the warranty?
• PV Modules 25 year performance warranty.
• Everything else 10 years.
3. How does it mount to my roof?
• We use systems specifically engineered
  for the type of roof you have and designed for 125 mph
  winds. The system we use adds a nominal load of under
  3 lbs/sq ft and protects your roof surface. For example,
  the solar array does not rest on top of your roof tiles.
• We attach directly to rafters for
  additional strength.
• Everything is thoroughly sealed from
  water with Sikaflex.

4. How long does it take to install?
• It depends on the size of your system.
  Typically 3 to 5 days.
5. How big of a system do I need?
• It depends on how much power you want
  to produce. It usually boils down to one of the following:

  1. Completely cover the load.
  We would need to review 12 months worth of bills to more
  accurately calculate system size.

  2. Employ a peak shaving strategy.
  We would calculate the system size required to eliminate
  the most expensive rate tiers on their bill.

6. Can I completely eliminate
   my electric bill?
• Unfortunately, there is a minimum
  fee to remain connected to the grid, usually about $.17/day
  or less than $6/month.
7. How much space does the system
   use?
• A 400kWh/month system uses less than
  300 sq ft.
8. What kind of maintenance does
   the system need?
• The PV modules should be cleaned at
  least every 3 months. No other routine maintenance
  is required. If you suspect a problem, please call
  us and we will come out and perform a thorough
  inspection.
9. Does the system use batteries?
• No, the system does not store electricity.
  If you are producing more power than you are using, your
  meter spins backwards. If you are consuming more than
  you are producing, your meter spins forwards. In the
  summer, your meter will spin backwards more often than
  during the winter.
10. How does having a PV system
    affect my utility billing?
• You enter into what is known as a "Net
  Metering"
  contract with your utility. The utility continues to read
  your meter monthly. However, instead of sending
  you a monthly bill, they send you a statement showing your
  credits and debits. Your bill is settled
  annually on your anniversary date. Unfortunately, you are
  not
  paid for any credits; however, the kWh credit is
  rolled over into the following year.
11. What is Net Metering?
• See FAQs 9 & 10.
12. I live in an HOA (Home Owner's
    Association). Will I be able
    to install a PV system on my home?
• Absolutely! California Civil Code
  2473, otherwise known as the Solar Rights Act, restricts
  HOAs and local governments from interfering with solar
  installations except for health and safety issues.
13. I see that the PV system
    increases my home's value. Won't
    that also increase my property taxes?
• No. In order to promote the use of
  renewable energy, the State has exempted PV installations
  from increased property taxes.
