Solar Myth Busting: Too Much Snow for Solar

Solar panels still generate power under snow
Myths get started all the time as we try to understand something complicated. We make up a story as an explanation, and the more times we say it and share it, the more that myth sounds like truth. So, we are going to bust some myths by sharing the simple facts about solar. This doesn’t have to be complicated and these myths are no longer necessary to get solar.

Myth: There’s too much snow for solar in the Midwest

Fact: Solar panels still work in snowy parts of the country and in some situations can work more efficiently that during summer months.

It’s true that when your solar panels are completely snow-covered, they will only be able to generate a portion of their typical energy output because less sunlight is able to pass thru the snow cover.

That being said, this is nothing to be concerned about because:

  • Solar creates more efficient energy at cooler temperatures.
  • The sun will warm up the dark solar panels and the snow will quickly melt and/or slide off the smooth surface, so no need to clear the snow off yourself.
  • Even in the dead of winter, solar panels give off some small amount of heat, which can prevent snow from sticking in the first place.
  • In working with Third Sun Solar experts in the design of the array, the shorter days, weather, and less direct sunlight is taken into account to optimize your system. Net-metering will allow you to continue receiving electricity when your array produces less.
  • As a percentage of overall yearly production the loss from some snow is very small.
  • When snow is on the ground and the panels are clear, the snowy surface basically acts as a mirror and in many cases, you end up with a small boost because of the reflection off the snow.
  • Snow sliding off panels as it melts simultaneously cleans them.

We recommend not trying to clear the solar panels. Getting onto a roof in inclement weather is dangerous and using any type of tool on the panels themselves can damage the panels.

3 Solar Power Predictions for 2016

Welcome 2016

Quite a lot happened in 2015 that will bring improvements to our homes and environment. Now that 2016 is here, we wanted to make some solar power predictions around what we think is in store for the Midwest.

1 – More homeowners will go solar. The renewal of the ITC will allow solar installations in the Midwest to catch up to what has been going on in the coastal states. More and more homeowners will turn to solar this year as they watch their electricity bills increase due to rising costs of fossil fuels and rate hikes approved by PUCO.

2 – Storage is going to be talked about more than installed this year. We don’t think 2016 is the year for energy storage, although it will start creeping more and more into the media. We’ve already seen the excitement building around energy storage prototypes, but in the Midwest, we think it will be a few years away until energy storage provides financial benefits.

3 – Solar installation prices will continue to drop, although only slightly. PV modules have already seen significant price cuts over the last few years, so any future drops in price are more likely to come from installation innovations. These types of efficiency changes are only likely to result in small cost cuts and not on the scale as has been witnessed one the last few years.
