Solar Energy

Q: How many solar panels does my house need?
A: It is impossible to know how many panels your home will need without some basic information. We need to understand your system goals to help you figure the number of solar panels you will require.

• Capture power for your entire home?
• Capture power for part of your home?
• Sell back to utility?
• Power a battery backup system?

Q: Will my system meet code requirements?
A: Our installations comply with National Electric Code Standards. With an Alaskan bonded and licensed Specialty Contractor, Renewable Energy Systems utilizes administrators and licensed electricians to oversee its installations.

Q: How long will a photovoltaic system last?
A: Renewable Energy Systems uses PV panels from top of the line suppliers like Sharp, Sanyo, Sunpower, Trina, Unisolar, and others. These products offer limited warranties of up to 20 to 25-years. Although solar panels have a useful life expectancy of more than 40 years, it is normal for panels to slowly degrade as they age, causing some decrease in output. This rate of degradation is typically about 0.5% per year.  RES can review the life of each of your systems components (panels, inverters, batteries, generators, etc.) at design time.
