How much do solar panels cost?
When comparing solar panels of different wattage, they’re normally compared by the cost per watt rather than the actual cost of a solar panel.
For example, if you have two panels costing $200, but one is 300W and the other is 350W, the 350W panel would be a better deal.
$0.66/W vs $0.57/W
On that note, to provide context, if you are looking to buy 27 panels for a system, Renvu has solar panels ranging $0.40/W (Risen 330W module currently on sale) and up to $0.88/W (Solaria 350W premium solar panels).

Why is there such a big difference in price between solar panels?
• What size is it? 72cell or 60cell? Since 60cell modules are smaller and easier to install for residential projects, they can cost more for the same wattage. While 72cell modules are usually used for commercial projects, customers often use them for residential projects too.
• Is it a mono-crystalline or poly-crystalline panel? Mono has historically been considered higher quality.
• What is its efficiency? The higher the efficiency, the higher the price it can command.
• What wattage is it? The higher the wattage, the higher the price typically. A 60cell 350W panel allows you to fit more panels on your roof and the wattage makes it more efficient per panel.
• Is it all black? If you care about aesthetics, it will cost you extra which is why Solaria is a premium-priced panel.
• How long is the warranty? 10 years or 25 years? For example, Solaria commands a 25 year warranty.
