Home solar panels are an investment that will repay a homeowner with cheaper electricity costs. In addition, buying home solar panels will also be helpful to the environment. Like any investment, home solar panels need to perform as anticipated when they are purchased and buyer's regret is an unfortunate outcome because installing these are permanent. If all goes well, home solar panels can last for up to 25 years, so it is vital that the right choice is made when buying. Tax credits on both the federal and state level make this a much more affordable and lower cost investment. Provided that the cost for the product and installation is less than the savings on energy bills over the life of the solar panels, then it makes economic sense to install home solar panels. Ask these questions about home solar panels answered.
Home solar panels will last anywhere from 12 to 25 years. After that time, they rapidly degrade and lose their ability to convert sunlight into electricity. Some home solar panels can last as long as 30 years. One of the longest lasting solar panels is SunPower, whose products will last up to 25 years.
Is SunPower the Most Efficient System?
SunPower sells the most efficient home solar panels. Their product can convert over 22 percent of sunlight into electricity, which is the highest percentage among all of the manufacturers of these products. SunPower's home solar panels cost $4.60 per watt, which is reasonable given its efficiency.
Which Solar Panels Will Work the Best for the Longest?
Again, SunPower is the best-in-class here. Their panels degrade at only .2 percent per year, meaning that they maintain their efficiency for most of their lifespan. SunPower's panels do cost more than the industry average, but they are efficient and long-lasting products.
Does Panasonic Have the Best Temperature Coefficient?
The temperature coefficient is the amount that power conversion will decline when weather varies from the ideal temperature. For example, when the temperature reaches 95 degrees, some panels may only produce 90 percent of their capacity. Panasonic's solar panels have an industry-leading temperature co-efficient and they cost $3.86 per watt.
Are Prices Rising or Falling?
Solar prices have dropped as the technology has improved. Combined with the tax rebates and credits that are available when purchasing a home solar panel system, there has never been a better time to buy this system for the home. Tax credits will greatly lower the cost of purchasing home solar panels.
Is REC Solar a Good Value?
The industry average can be as high as $3.57 per watt, but prices are state-specific. REC Solar is one of the more affordable names in the industry in comparison to the average price. Its home solar panels cost only $3.28 per watt and provide a reliable value for the money.
What About Canadian Solar?
Canadian Solar is a reputable and well-known name in the business. Their panels have above-average efficiency. Their products are competitively priced $2.87 and $3.30 per watt, which is well below the industry average. While the price is low, the performance is not. They sell their products on six continents, so they are an established and reputable name in the industry.
How Are Home Solar Panels Priced?
Buyers will not necessarily receive a one-size-fits-all price when purchasing home solar panels. Instead, they are priced per watt. This makes sense because each home may require a different amount of solar power in order to meet all of its needs. For example, Solar City's panels cost $4.25 per watt. If 7,000 watts are needed, the system will cost roughly $30,000.
