If your need for energy is highest in the winter, your roofing specialist may recommend that you leave your photovoltaic panel system on the winter tilt all year long. To calculate the best tilt for photovoltaic solar panels in the winter, take your latitude, multiply by 0.9 and add 29 degrees to your total. The result of this calculation will give you the appropriate angle at which your PV solar panels should be tilted in the winter season.
Adjusting Photovoltaic Solar Panels Seasonally
Although it’s a little more work, adjusting your PV panels seasonally will net more energy to use, store or sell back to the utilities. The optimal angle of tilt for spring and autumn is your latitude minus 2.5 degrees. The ideal angle for your PV solar panels in the summer is calculated by subtracting 52.5 degrees from the winter angle.
Understanding your Solar Panel Roof
A photovoltaic roof uses an interconnected PV panel system to capture sunlight and convert it into electricity. The conversion is pollution free and silent, as it involves no moving parts. Captured energy is fed directly through each PV panel on the roof and converted to utility-grade electricity for use in the home or business on which the photovoltaic solar panel system is mounted.
Photovoltaic Solar Panel Features
A photovoltaic solar panel is typically rigid and rectangular in shape, ranging in size from 2′ by 4′ to 4′ by 8′. There are however, some flexible PV panel systems that are as large as 2′ by 20′ or more. Rigid solar PV panels usually have a glass cover, whereas their flexible counterparts feature a durable film cover. Both rigid and flexible solar roofs are designed to withstand harsh weather conditions including storm and hail damage, and are obviously resistant to deterioration from UV rays. Solar photovoltaic roofing will create power for your home or business for many years. The excess power that your roofing creates can be sold to utility companies and actually create profit for your business. Kirberg Company also will provide you with a twenty five year guarantee on our installations and will show you results instantly through our interactive display, which will show you the energy production of your roof in real time. Photovoltaic solar panels will allow owners to realize financial profits, enhance your building’s public image, and pay for itself through tax incentives, sales, and energy savings.
Types of Photovoltaic Roof Systems
There are two main types of photovoltaic roof systems on the market. Solar PV panels, described above, are the most commonly used systems for solar energy roofing. Solar thermal collectors, on the other hand, convert sunlight into thermal energy instead of electricity. The primary purpose of solar thermal collectors is to heat water. These systems are often installed on a roof alongside PV panels for optimum, whole-building energy capture.
