Get matched with top solar panel pros in Harvard, NE

You can install solar panels on a metal roof, but it will require some additional thought and care versus a traditional asphalt shingle roof. That’s because heat dissipates off a metal roof differently than asphalt or wood, so you may need to space the panels further from the roof. However, a pro can help you with the details and provide a safe and effective installation.

The average homeowner needs around 22 solar panels, but the exact number depends on your monthly energy consumption. Your solar professional should size your array to offset your consumption, meaning you’ll need fewer panels if you use below-average amounts of electricity, or more than 22 if you use above-average amounts of electricity. The number of panels also depends on the output of each panel. The average is around 400 watts, but you might need more panels if you install less capable equipment. Since there are so many variables, you should have a professional size your system.

Although solar panels harness the sun's power, they come at an environmental cost. The manufacturing process requires large amounts of water and involves hazardous materials like cadmium, silicon, and gallium arsenide. These materials don’t pose safety hazards while the panels are in use but can pose a problem when left in landfills. Over time, hazardous materials can leach into the environment. This is why recycling solar panels whenever possible is better than taking them to landfills.

For most U.S. homeowners, switching to solar energy is an excellent investment. A properly sized solar array can significantly reduce your electric bill, saving money on utilities every month. Most homeowners enjoy savings that cover the cost of their solar systems within 12 years and then turn a profit. Additionally, federal and state tax incentives are available that help make solar an even better and more profitable investment.
