Denver, COâMercy Housing, Inc., one of the nationâs largest affordable housing nonprofits, is launching a partnership with Promise Energy, Inc. to increase solar energy use across Mercy Housingâs portfolio. Since affordable housing communities usually operate on thin margins and have limited roof space, they often struggle to implement solar energy programs…
Letâs face it: life happens. You may be planning to install solar at your house this month, but five years down the road you could get relocated for work and have to sell your house and move elsewhere. Or, you might be living in a home that you expect to outgrow but arenât quite sure of when that next move will happen. The question is, when you donât know if…

While the technology behind solar energy may seem complex, when broken down, how solar power works is easy to understand â particularly in a grid connect scenario as it only requires a few components installed in your home or business. The sun shines on the solar panels generating DC electricity The DC electricity is fed into a solar inverter that converts it…
The consumption of non-renewable sources like oil, gas and coal is increasing at an alarming rate. The time has finally come to look after some other renewable sources of energy i.e. solar, wind and geothermal energy. Although many countries have started utilizing solar energy extensively but still they have to go a long way to exploit this energy to fulfill…
Green and clean energy have become such popular buzzwords that the mainstream public is becoming aware of sustainable alternatives to traditional energy sources. Solar is one such alternative. Unfortunately, with a tough economy and bleak job market, most people feel they donât have the money to invest in solar. Luckily, cheap and easy solar alternatives do exist…
Solar panel electricity systems, also known as photovoltaics (PV), capture the sun s energy using photovoltaic cells. These cells don t need direct sunlight to work â they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting. The benefits of solar electricity…
After years of tweaking by other scientists, researchers at MIT have figured out how to chemically stabilize plant-derived photosystem-I (PS-I), the structures inside plant cells that perform photosynthesis, on a substrate that creates electric current when exposed to lightâall using readily available materials. The newly created solar cell isolates PS-1 molecules…

The next time you need to pick up 48 rolls of toilet paper, five gallons of Dijonnaise and the complete works of Tim Conway on DVD, you might as well grab a 3.7-kilowatt solar system while you re at it. Costco is selling solar systems that range in size from this 3.7-kilowatt system for $13, 500 to an 800-watt job for $3, 600. The systems come with microinverters…
DIY: Three letters that have the power to send either titillations of excitement or bolts of pure terror down your spine. Myself, I fall into the second group. To me, âDo-It-Yourselfâ sounds more like a threat than an exciting proposition. DIY solar panels?! Youâve got to be kidding me. But yes, itâs true! Plugged Solar is a start-up based out of Houston, TX…
Do-it-yourself (DIY) solar is a booming industry, and there is no shortage of assembly kits available online. You can even buy affordably priced solar kits from local hardware stores like Home Depot. Whether youâre a solar veteran or a weekend warrior, the allure of these inexpensive photovoltaic (PV) panels is easy to understand. Why hire a professional to install…
Solar cell design involves specifying the parameters of a solar cell structure in order to maximize efficiency, given a certain set of constraints. These constraints will be defined by the working environment in which solar cells are produced. For example in a commercial environment where the objective is to produce a competitively priced solar cell, the cost…
To answer that question, you need to think carefully about your goals. The decision you make shouldn t be based solely on how to save money on electricity. You can lower your energy costs whether you buy or lease solar panels, so immediate savings shouldn t be your only concern. Customers who choose to buy a solar panel system are usually focused on maximizing…
Solar is no longer the uncommon renewable energy it once was. Today, trusted review organization Consumer reports is offering its insight about the best solar companies and best ways for consumers to install solar panels.This year, the millionth home solar panel system was installed in the United States. If you had any doubts about whether solar is now in the…
Introduction Solar electric systems are a popular choice among renewable energy options due to the relatively low maintenance requirements and the long lifetime of many of the system components. Because there are no moving parts, and thus little chance of mechanical failure, most solar electric systems will continue to produce power for 30 years or more! Although…
Solar intertie photovoltaic (PV) systems are not particularly complex. First there are panels, which collect the sunlight and turn it into electricity. The DC signals are fed into an inverter, which converts the DC into grid-compatible AC power (which is what you use in your home). Various switch boxes are included for safety reasons, and the whole thing is connected…
The coating consists of nanoparticles and organic materials. The former absorbs the infrared photons and passes the energy onto the latter, which emit fewer, but higher-energy, visible-light photons. âPut simply, the inorganics in the composite material take light in; the organics get light out. This 550-nanometer light can be absorbed by any solar cell material…
As of September 2012, the top 20 (in terms of on-site solar capacity deployed) are: Walmart (WMT), Costco (COST), Kohlâs Department Stores (KSS), IKEA, Macyâs (M), McGraw-Hill (MHP), Johnson & Johnson (JNJ), Staples, Inc. (SPLS), Campbellâs Soup (CPB), Walgreens (WAG), Bed, Bath & Beyond (Y), Toys âRâ Us (TOY), General Motors (GM), FedEx (FDX)…
Here is a low power low efficiency photovoltaic cell that you can make you own in the kitchen with materials from the hardware store. This cell is made from cuprous oxide instead of silicon and you can build a working solar cell in 2 hours to build it i follow this instruction: on Step 1: Materials You Will Need A sheet of copper flashing from the hardware store…
In the last 10 years, homes with rooftop solar arrays have gone from curiosity to commonplace. It s a trend perhaps best exemplified by Home Depot s decision to start stocking solar panels in 2001 [source: DOE]. The technology has been available for decades - NASA has been using solar-powered satellites since the 1960s, and as far back as World War II, passive…
A cheap solar panel system will forever be the best solution to expensive electric bills. Solar cells are getting cheaper each year. While you could pay up to $10, for an off-the-shelf installation and could cover the systemâs price in just over 10 years, itâs still better and more educational to make one yourself. Letâs face it: weâre still living the post-traumatic…
