Are Solar Panels Dangerous for Firefighters?

Are-solar-panels-dangerous-for-firefighters

Solar energy is good for the planet, but are solar panels dangerous for firefighters?

Solar panels are a great way to ameliorate the harmful effects of climate change, lower our household energy costs and decrease nonrenewable energy dependence. But is there a downside to all this cheap energy – are solar panels dangerous for firefighters?

Solar panels, typically installed on the roof, are rigid and produce electricity (obviously), potentially making the area unsafe in an emergency situation and threatening firefighters’ ability to respond in a timely fashion. Many governments and first responder organizations have cast a spotlight on this difficult issue.

How do we reduce climate change without creating a hazard for ourselves and first responders?

How Big and Expensive Is a 6kW Solar System?

6kW-solar-system

How big is a 6kW solar system exactly and what does it cost?

Solar installations can be very small such as 2 kW (kilowatt) installations composed of just 8 panels, or they can be large 25 kW systems with over 100 panels! This large playing field for installation size might make a 6kW solar system look fairly small, but in all actuality it’s very close to the size of a vast majority of residential solar installations.

So what do 6kW mean and, just as importantly, how much does it cost? Read on to find out!Continue reading

Organic-Inorganic Hybrid Perovskite Solar Cell Could Quadruple Power Efficiency

pervoskite-solar-cell

Could an organic-inorganic hybrid perovskite solar cell be the Holy Grail we’ve been looking for?

Reaching a high power conversion efficiency has always been the goal of solar energy.

Last year, the development of perovskite-silicon solar cells by the Hong Kong Polytechnic University showed great promise by reaching the world’s highest power conversion efficiency of 25.5 percent. This was accomplished by designing a transparent perovskite layer with an optimized thickness that allowed the absorption of light into the silicon part of the solar cell.

Then a few months later, a team from Eindhoven University of Technology showed that adding a few nanometers of a thin layer of aluminum oxide would protect a perovskite solar cell against humidity while increasing power efficiency by three percent.Continue reading

The History of Solar Energy

history-of-solar-energy

In this post, we talk about the history of solar energy and how it developed throughout the ages.

For thousands of years, humans have harvested sunlight. It started simply – warming rooms with large windows or starting fires with mirrors – and led to today’s complex photovoltaic power plants with millions of solar panels each creating electricity.

Knowing the history of solar energy gives us a deeper appreciation for just how much work it took to get us to today’s modern solar technology. Below is just a brief overview of this story.Continue reading

What Do I Need to Know When Buying a House with Solar Panels?

Buying a house with solar panels already installed is a relatively new phenomenon. Read on to find out if it’s really worth it.

When you’re shopping for a new home, you probably have a checklist of things to do. First, you walk through the home to see if it fits your lifestyle. Next, you have your real estate agent run comps to make sure it’s a good deal. Lastly, you hire an inspector to check out the house and make sure everything is working well.

Buying a house with solar panels is no different. You need to know if the installation fits your lifestyle (more on that later) and if it makes financial sense for you to purchase, both in the short and long-term.Continue reading
