Some of the highest-speed trains in the world use solar panels for power, along with your homes and businesses although determining if they are right for you depends on a number of factors including capacity design life costs efficiency competition local climate etc. The installation costs between $15,000 and upwards of $25,000 for a typical 5 kW system in the U.S. which is quite hefty price tag however tax incentives such as the Federal Solar Investment Tax Credit cuts that upfront cost down by up to 30%. Solar panels can save up to 70% of energy bills, with a payback period for many households in the region of 6 -10 years.
Efficiency Solar panel efficiency (most often in the range of 15% to 22%) tells you what percentage of sunlight that hits your solar panels is converted into usable electricity. While high-efficiency models like monocrystalline panels work best for low sunlight areas, polycrystalline panels offer more budget-friendly options in sunny regions. Sun drenched states like California and Arizona stand to gain more advantages from solar power as compared to areas with many cloudy days.
Solar roof viability is also affected by the angle and orientation of a roof. While any rooftop that is facing east or west can still save you money on your energy bills, especially if it has a 30-degree tilt to maximize direct sunlight. Making the investment in solar means homes are sold for an average of 4% higher, reports SEIA — a positive image that many environmentally-conscious buyers will find hard to resist.
Durability matters as well. Having a warranty of up to 25 years granting at least an 80% efficiency, modern solar panels are considered clean energy that can also be turned into long term investments. Tesla CEO Elon Musk has said that “energy independence is the end goal” which aligns well with an ambition of solar panel users to cut costs and free themselves from utility companies, it also reduces their reliance on fossil fuels. Most of the systems require cleaning and minor repairs to be done on a regular basis, making maintenance costs remain low.
However, the cost of installation and rate of efficiency is important for consumers who are determining if solar panels are right for their home. For homeowners looking to minimize energy costs and decrease their carbon footprint, solar energy remain a viable option for both long-term saving money and sustainability.
