Consider this when doing a Sustainable Retrofit

Consider this when doing a Sustainable Retrofit

Sitting at home in the summer heat, your mind may start to wander to that fancy new air conditioner. But when it comes to making your house comfortable and sustainable, prevention is better than cure. By prevention we mean simple retrofits that will set you on the path to comfort and sustainability. As we spend more than ever on maintaining and improving our homes, we’re also becoming more aware of how their design and use impact on our health and society. Add to this climate change and rising energy costs.

Solar Power on Roseville civic campus?

Solar Power on Roseville civic campus?

It may be a way to save money on energy, but much remains unknown about the pros and cons of such a project. Roseville is thinking of turning City Hall into a power plant — and perhaps saving close to a million dollars in energy costs. But the issue now is caught up in a wider set of questions involving a potential facilities overhaul that could cost anywhere from $6 million to $14.5 million, at a time when Roseville schools are promoting a major facilities referendum of their own. The city is weighing a proposal to generate 450 kilowatts from…

Surface Color & Solar Gain: White is the Greenest Color

Surface Color & Solar Gain: White is the Greenest Color

The U.S. Environmental Protection Agency (EPA) says that for low-rise commercial buildings, the heat gain through the roof is about 50 percent of the heat gain for the entire building. This heat gain can be reduced not only by using more insulation but also by reflecting the sun’s radiation. The American Society of Heating, Refrigeration, and Air-conditioning Engineers (ASHRAE) states that the heat gain through a white roof is half of that of a black roof, and the heat gain through a white wall is two-thirds that of a black wall. Thus, in hot cli- mates, the walls should have…

Conext MPPT 80 Solar PV Charge Controller

Conext MPPT 80 Solar PV Charge Controller

Install for less, harvest more energy The ConextTM MPPT 80 600 solar charge controller offers an industry-first set of integration features and top performance that allows for large PV array systems to be easily installed and connected to the battery bank at the lowest overall cost. Installing one MPPT 80 600 is faster than installing multiple smaller charge controllers and lowers overall costs further by utilizing fewer PV strings, smaller wiring and conduit, and by eliminating the need for PV combiner boxes and DC circuit breakers.

Project Sunroof – Google your solar potential

Project Sunroof – Google your solar potential

If you’ve ever thought about putting solar panels on your roof, you know that the process doesn’t exactly qualify as an impulse purchase. Typically, it involves multiple visits from solar installers. The standard practice in the industry is to go up on the rooftop with a fish-eye camera, then take a picture from each of the four corners to make an estimate of the solar potential of the roof.

What is a grid-tied PV system?

What is a grid-tied PV system?

It is a photovoltaic (PV) system interacting with the utility, with or without batteries, that uses a relatively new breed of inverters that can actually sell any excess power produced by your solar array back to the utility grid. If you are concerned at all about your utility rates going up and would like to do something to reduce your monthly electric bill, then a grid-tie solar system may be just the thing for you.  These systems are easy to install and since some do not have batteries for back-up, the lack of batteries in these systems means no messy maintenance or replacements…

Booming Renewables

Booming Renewables

Buyer Beware. Falling costs and increasing adoption are wonderful news for clean energy, but now is not the time for celebration. A new report from the U.S. Department of Energy suggests that the costs of renewable technologies are tumbling, and with it their adoptions soaring. But despite the good news, we can’t become complacent.

Bifacial Solar Panels

Bifacial Solar Panels

San Diego, Calif. — Bifacial PV modules have been in the market for some time, but with limited usage. The BIPV applications such as awnings and canopies have been a niche market for bifacial PV modules because of glass-on-glass, see-through, aesthetic looks. They have also been used, because of their vertical install-ability, as railings or sound barriers at highways and railways or other places where space for installing standard PV modules is limited. But, are bifacial PV modules ready for larger deployment in the growing PV industry?

The photovoltaics of the future are transparent

The photovoltaics of the future are transparent

In case you’re searching for the sun panel of the future, why no longer don’t forget those created via the aptly-named SolarWindow technology, which transform regular home windows into photovoltaics, capable of generating 50 times greater electrical power than rooftop panels, while modeled for a 50-tale building. “Simply choose up your mobile phone, observe the face without any strength or photo, and also you’ll see a quite accurate instance of what today’s thin film looks as if,” John Conklin, CEO of SolarWindow, instructed digital trends. “It’s heavy, it’s too darkish to peer via, and most skinny-film is not bendy. This…

The future of residential solar power

The future of residential solar power

Electric cars, the hyperloop, space travel: Tesla’s Elon Musk, master of futuristic technologies, always has a plan. But speculation about the company’s recent $2.8 billion purchase of SolarCity, the green energy behemoth building a massive solar panel factory in Buffalo, New York, suggest that while Musk has compelling visions for the future, even he may not have a handle on a technology seen as a key part of the future of sustainable energy. A midcentury creation, modern solar power has repeatedly been championed as a solution to our energy woes. But especially in the United States, the technology has never lived up to…
