How Photovoltaic Panels Are Impacted by Arizona’s Summer Heat

Here in the Valley of the Sun, photovoltaic panels are incredibly valuable to homeowners by enabling clean, affordable power for air conditioning, lighting and home appliances. Yet, it’s important to understand how the high temperatures that we experience during the summer months can impact solar panel function.

As temperatures rise, solar panels can produce less electricity from the same amount of sunlight. This is caused by heat changing the speed at which the electrons in a solar cell travel. This speed reduction impacts the flow of electricity. By some calculations, for each degree the mercury rises above 107 degrees Fahrenheit, there is a 1.1 percent decrease in panel efficiency. Considering that solar panels can be up to 20 degrees hotter than air temperature, this is something to consider.

Reducing the Effect of Extreme Heat on Photovoltaic Panels

The good news is that there are steps to minimize the impact of high temperatures on solar panels. This begins with choosing a solar provider who uses quality panels that are constructed from lighter materials. Darker colors simply absorb more heat, so they’re inherently less effective in hot conditions. Installation is also critical to panel effectiveness. In hot temperatures, panels that are installed a few inches above the roof can enable airflow that helps keep them cooler and more productive.

FAQ's

Is Solar Energy Expensive?

The size of your panel installation and the needs of your home will affect your costs. The average net cost of a 5.69kW system is $13,838 cash after 30% rebate (according to solar-estimate.org). An average-sized system can cost up to $35,000. Larger installations will require more hardware, planning and construction time. This can further increase costs. While solar panels are expensive, they have many distinct benefits. Cool Blew Electric & Solar’s experts can assess your situation and goals and recommend a cost-effective system to meet your needs.

How Much Can I Save By Installing Solar Panels?

An average-sized system (5 kilowatts) can reduce up to 50% of your monthly electricity bill. A 5.69kW system would offset 100% of your energy usage if your typical monthly bill is $138. Over a period of 20 years, these savings can add up to $30,000, based on your location and energy usage.

How Long Would It Take to Recoup My Solar Investment by Solar Energy Savings?

With a 5.69kW Solar system you would recoup your savings in 7 years and 2 months but with continuous Utility increases every year your Return and Investment will be much sooner.

What is a Solar Lease Program?

The Solar Lease Program has been one the most popular option that homeowners have chosen over the years. Solar Lease programs gives homeowners the opportunity to take advantage and put Solar on their homes and a guaranteed savings from their Utility for little to no money out of pocket. Most Leases are 20 year power guarantee from the solar provider and includes fixed monthly payments, no repair cost, fully insured and warrantied for the life of the system.
