400 watt solar panels: a consumer guide
Solar panel efficiency keeps getting better. Back in 2013 - which really isn’t that long ago - I had 260 watt solar panels installed on my home. Today, most homes will use solar panels in the 300+ watt range. But now, manufacturers are starting to put out panels that exceed 400 watts. These products are at the premium end of the market, which means that you can expect to pay more for them.
