Common Solar Power Questions

Below are answers to many common questions about solar power.

Q: What are the financial reasons to go solar?

A: The cost of energy from the U.S. utility grid has increased at an average rate of 5%, year over year, since 1932. Almost every credible analyst anticipates much more rapid rates of increase in the coming years as the world's finite supply of fossil fuels, which generate the majority our electricity, is reduced by increasing demand from large emerging markets. In comparison, the cost of solar power is fixed, or provided at predetermined escalation rates.


Q: Will the system work on gray, cloudy or overcast days?

A: Yes, because photovoltaic energy (PV or solar power) uses the full spectrum of light, the ultraviolet rays are still charging the system, even when the sunlight isn't visible.


Q: How does it work with the utility grid?

A: The solar panels generate electricity when exposed to sunlight. This electricity is conditioned by the power inverter to match the electricity coming from the utility grid.


Q: Does the system work when the regular power (the utility grid) is down?

A: Yes, if you choose a system that has a battery pack, it will provide power to those circuits you select as critical loads. You might choose the refrigerator, computers, some lighting circuits, heater fan, TV or whatever you feel should have back-up power.


Q: What are the components involved in a solar system?

A: The following items are used in most solar installations:

  • Photovoltaic Modules - Photovoltaic cells absorb the sun's energy and convert it into DC electricity.
  • Inverter. An inverter converts DC power from your PV modules into AC power that is the electricity used in your home/business/workplace.
  • Electric Box - The breaker box distributes AC power throughout your home/business/workplace.
  • Utility Meter - Your utility meter measures the amount of DC electricity that is used.
  • Monitoring System - Your monitoring system lets you know, in real-time, how much electricity is producing.


Q: Does a warranty program cover the system? How long will my solar electric system last?

A: We provide a 10-year complete system warranty, including labor and equipment. The solar modules warranty last for 20 to 25 years.The electricity inverter box warranty is for 5 years. With proper maintenance your system should last for a minimum of 25 years.


Q: What happens when we generate more power than we’re using?

A: Excess electricity is fed back into the utility grid for others to use. Your electric meter spins backwards to credit you for all energy sent into the electric grid. You are billed for the difference between the electricity you generate and the energy you use.
