Here in the northern hemisphere, it is commonly advised that the best direction for solar modules to face is south. This is because your modules would, in theory, receive the most direct sunlight. But of course, not all rooftops are oriented this way. So what are your solar PV options for a non south-facing roof? Read the rest of this entry »
It’s been a good year for solar. Jobs are on the rise. Over one million solar systems have been installed across the country. Innovations continue to wow the world (floatovoltaics, solar flowers, and a solar plane to name a few).
As we push forward toward a clean energy future, we must constantly assess and improve upon our processes, our technology, and our methods of communicating the value of solar and sustainability to the public. While not all-inclusive, the recent publication of Solar Power World’s Top 500 Solar Contractors report offers a glimpse into the current state of the industry and the direction we are heading. There’s much to be gained from assessing the key players and sectors of the industry that have pulled ahead—and those that are falling behind. Read the rest of this entry »
There are many different factors that go into estimating your solar savings. A few important ones include the following:
The primary requirement for a solar PV system to work is UV light. Direct light works best, but solar modules can still operate with indirect light. Clouds and rain are not opaque barriers through which light cannot get through, meaning sunlight can reflect or partially break through the clouds and reach the rooftop solar energy system. Solar systems are able to operate at night and at other times when the sun is not directly shining on the solar modules because the system harvests and stores unused energy for future use.

Absolutely! And now more than ever. With the signing of the Paris Climate Agreement, hundreds of countries around the world have committed to reducing their carbon emission output. Solar plays a big role in these reduction goals by swapping sources of carbon-emitting energy like coal and other fossil fuels, which contribute to the warming of the planet, with sources of non-carbon emitting energy. Because solar photovoltaic (PV) systems do not emit carbon pollution, they are a great option for meeting our world’s renewable energy goals. Read the rest of this entry »
