Solar Energy

Solar energy is the light and heat from the sun that is collected and transformed by devices like solar panels or solar thermal systems into electricity. It is a clean, plentiful, and renewable energy source.

What is solar energy?

Solar energy is a renewable power source generated from sunlight. It’s created when photovoltaic cells in solar panels convert sunlight into electricity. This clean energy is used to power homes and businesses, helping lower costs and reduce environmental impact.

Solar energy minimizes reliance on fossil fuels, cuts electricity costs, and is environmentally beneficial. You can also use stored solar power at night or on overcast days with the aid of battery storage. 

Why is Arizona a prime location for Solar Energy?

Arizona receives some of the greatest levels of solar radiation in the country, making it a perfect place for solar power. 

The state's large open spaces and more than 300 sunny days per year provide steady, plentiful sunlight ideal for energy production. In addition to lowering cloud cover and maintenance requirements, Arizona's dry environment enables solar systems to function effectively and produce the most energy possible all year round.

What is a Step-by-Step Guide to Going Solar in Arizona?

Switching to solar is simpler than you think. Here’s a quick overview of the process from start to finish:

• Initial Assessment & Research – Check your roof condition, energy usage, and sun exposure to confirm your home’s solar potential. Get a professional evaluation.

• Find a Reputable Installer – Choose licensed Arizona contractors and look for NABCEP certification.

• Consultation & Proposal – Installers assess your home and provide detailed proposals outlining system size, cost, savings, and equipment.

• Financing, Permitting & Installation – Select your financing option. Your installer will manage all permits and city paperwork.

• Inspection & Interconnection – After inspections by the city and utility, you’ll receive Permission to Operate (PTO). The full process usually takes 6–10 weeks in Arizona

How do solar panels generate electricity, especially on cloudy days in Arizona?

Photovoltaic (PV) cells in solar panels absorb sunlight and transform it into electrical power. Solar panels work on cloudy days because they can absorb scattered sunlight from clouds and nearby surfaces.

Although there may be a tiny decrease in energy output during cloudy conditions, Arizona's lengthy daylight hours and generally brilliant sky guarantee that this decrease is negligible. Over the course of a year, the state's plentiful sunshine easily makes up for the occasional overcast day, maintaining solar panels' high productivity and efficiency.

How long do solar panels last in the intense Arizona climate?

Solar panels are built to withstand Arizona’s intense heat, strong sunlight, and desert winds. Made with corrosion-resistant materials and tempered glass, they are tested to perform reliably for 25 to 30 years. 

Most manufacturers also offer 25-year performance warranties to ensure consistent power output. With proper installation and care, panels can continue producing clean energy even after the warranty period. 

If they don’t perform as expected, A professional maintenance service
from Sunny Energy RX can quickly identify and fix the issue.

What are the main challenges and downsides to consider?

Even if there are certain obstacles to take into account, most may be overcome with careful planning and system design. Although solar energy requires a large initial investment, it frequently pays for itself in a matter of years because of financing options, federal tax incentives, and long-term energy savings.

Savings can be increased by combining solar with a battery system, and Arizona's net billing policy provides equitable reimbursement for excess energy transferred to the grid.

Time-of-use (TOU) rates offer potential to save more by moving energy use to daylight hours, despite the fact that they may initially appear complicated.

What is the difference between buying and leasing a solar system?

When deciding between buying and leasing a solar system, the key difference lies in ownership and long-term benefits.

• You own the equipment and are qualified for any benefits, including federal and state tax credits. Your power is practically free once the system is paid off. Ownership also boosts the value of your property when you sell it and offers the biggest long-term savings.

• Lease or Power Purchase Agreement (PPA)- You pay a set monthly charge for the power use and pay little to nothing up front. Although this lowers the upfront costs, the system doesn't increase the value of your home; instead, the tax benefits go to the solar supplier.
