SunPower panels have received high praise for their efficiency, high cost effectiveness ratio and extended warranties. They can be used for solar energy systems both in residential and commercial buildings. These panels are also extremely affordable, and they do not need to be installed in a special way, which makes them the best option for people who have limited budgets.
Prices
SunPower panels can be costly, but there's a way to reduce that price. You should first check with your local government about incentives to install solar energy system. You might be eligible for a lease or loan from the solar company. Also, don't forget about the federal solar tax credits!
SunPower solar panels have a 25 year product warranty. This is another reason to purchase them. This guarantee covers material or workmanship defects and is valid so long as panels are used properly. SunPower's 12-year warranty is more than any other manufacturer. The warranty also covers installation.
SunPower offers free online consultations to homeowners so they can ask questions about their system design. After the consultation, SunPower will provide a proposal outlining the system design and estimated price. Once you approve the proposal, SunPower will get the necessary permits and complete the paperwork. It is important to allow at minimum a few months for this process.
Efficiency
SunPower Solar Panels are some of the most efficient on the market. PV Evolution labs has found that SunPower panels rank in the top half of all solar panels. This company also has the second highest temperature index of any manufacturer. Its solar panels are expected to produce 470 billion kilowatt-hours of solar electricity in the first 25 years, enough to offset the emissions of 30 million tons of coal.
SunPower solar panels are relatively affordable when compared with other brands. These panels also boast a high efficiency rating at 21.5%, which makes them more efficient than other solar panels. Monocrystalline cells also look beautiful on the roof.
Warranty
There's no guarantee that your solar panels will last as long as the SunPower warranty, and there are some conditions you should be aware of. The most important one is that the panels must be in good condition. Cracks and other damage to the cells, such as browning, do not qualify for the warranty. Also, the panels must have a minimum power output level to qualify for the warranty. Gary didn't want to have the panels tested by the solar installation company, so he called SunPower helpdesk.
There are other manufacturers of solar panels, but SunPower offers the best product warranty available. The warranty covers all defects, power output protection and repairs to defective panel for forty years. The company's policy is based upon data from 33 million IBC panel installations around the world and external field studies. The PVLife physics model allows for continued operation even after the warranty expires.
