1. Shading - Tree shading on your property can really affect the efficiency of a solar system. The solar cells in an array work as a team. We have all heard the anecdote, "You're only as strong as your weakest link." That same principle applies to solar panels. Trees casting large shadows on your house will need a trim if a rooftop solar panel is going to be able to produce the amount of electricity it is capable of generating.
At PEP solar our 2nd Generation and 3rd generation modules and TRUEAC and Optimizers allow your panels to work individually. Our 3rd generation thin film modules can be 92% shaded and still operate with only 8% module sunshine and your system is still producing power.
2. Roof attributes - The condition of a home's roof is another big consideration before jumping ahead with a solar installation. The best place for a solar panel is on a roof that is facing south. The next best direction is to face panels west, then east, the north (reverse tilt). The further away they become but in Arizona its a small difference from South or West Facing. Even utility companies are encouraging Arizona residence to face their panels west. Contact us to provide you with our roofing partner.
The pitch, age and condition of the roof also are important for maximum solar panel efficiency. As a certified, utility-preferred solar installer, and the oldest residential solar electric installer in Arizona, we are able to help determine the optimum angle the panels should be installed for maximum solar collection. The age and condition of the roof are a bigger issue because it would not be an ideal situation to install solar panels onto an aged and worn roof. If a roof installation is not possible, a ground-mounted solar unit may be an alternative.
3. Repayment period - There is no upfront cost (on approved credit for the entire amount) when installing a solar panel system. There are not short term 18 months no payments no interest, or 12 months no payments with long term rates starting at 2.99%. The average pay off time for your solar system is 6 to 7 years for Arizona utility companies. As the electricity you produce with a solar system offsets the amount needed from an electric company, the saved benefits will help pay down the costs of the solar panel. When researching solar systems and determining how much it will save you, it is important to know that solar systems at homes that use less electricity will have a longer pay back period that homes that use more.
4. Energy use - the amount of electricity used in you home can help you determine if solar is the best fit for your home. You should review your utility bills with one of our energy specialists by calling (623)806-8806 to determine the amount of electricity, in kilowatt-hours, you use over the course of a year. With this information, you can work with one of our energy specialists to determine the amount of electricity you would like to be powered from solar energy. It is possible you may be able to offset most of your entire yearly kilowatt usage.
5. Certified Solar Installer - To qualify for the state and federal incentives that help with purchasing a solar system, you must use a certified installer.
