When it comes to solar, not all panels are created equal. As with any large purchase or investment, it pays to do your research. In looking for a brand that will work for your needs, here are some things to consider:

• Cost
• Efficiency
• Warranty
• Available space

Cost

How much do you plan on spending? Everyone likes to get the best price for the best product. Research panel performance on multiple brands, then set a budget and look into financing options.

Efficiency

Solar panel efficiency varies widely depending on the manufacturer. The chart below shows the top ten efficiency-rated solar panel brands currently on the market (comparable models were used in processing data):

Warranty

Solar panels should come with a warranty of 25 years minimum. And if there’s a problem? Make sure the manufacturer is established and will be there for the long haul. Don’t choose a fly-by-night installation company just to save a few extra dollars; you’ll end up paying for it in the long run.

Available space

Where is your solar array going to go? On the roof? On the ground? Most people only have a limited amount of space, so fitting the best performing panels in the space available would be the wise choice.
