Get started with home Solar!

When you decide you want to put a solar system on your home there are some things to consider before you get started. You'll want to find the right place to install the solar panels so you get maximum exposure to the sun, you'll need to assess your power needs to understand the amount of panels to use and the battery storage requirements. The first thing you should do is to use a checklist and find out what your power usage is on a monthly basis. Each of your appliances will use a certain amount of power and depending on what your lifestyle is, you'll learn what unit is using the most power and how to assess your overall power needs. The following chart will give you an idea of some standard wattage usages. These are some wattage ratings for typical household appliances and home electrical devices. Check the rating on your personal items for an accurate wattage count.

Light Bulbs - 60 / 70 Watt60/70
Dishwasher1500
Refrigerator / Freezer700*
Microwave1000
Coffee Maker1000
Electric Range1200
Radio / Television50 - 500
Security System500
Computer w/17" Monitor800
¼ HP Garage Door875
Clothes Dryer5000
Washing Machine1500
Toaster Oven1500
Hot Water Heater5,000
Blender300
Stereo300-450
Ceiling Fan100
Floor Lamp100
Hair Dryer600-1200
Window Unit750-1200
Hedge Trimmer450
Lawn Mower1200
Weed Trimmer500
Edge Trimmer500
Furnace Fan Blower - ⅓ HP700*
Window AC - 12,000 BTU3250*
Central AC - 10,000 BTU1500*
Central AC - 24,000 BTU3800*
Heat Pump4700



Next you would calculate the Watt Hour which would be the Wattage rating times the hours used. Load Calculation Example:Lets say you want to run a 11W compact fluorescent lamp (CFL) for 5 hours from a solar panel, then the watt hour is equal to:
Watt Hour = 11Watts x 5 hr = 55 Watts
Once you have calculated your total monthly wattage use you can get an idea of what size of solar array to install in your home. This is the first step you need to take in order to properly plan your home solar installation. Stay tuned for the next step

No One Saw Tesla's Solar Roof Coming


Elon Musk is a true visionary with his dreams of Electric Cars, space exploration and now Solar Roofs that are indistinguishable from ordinary roofs. In this article from Bloomberg news we see roof shingles made of textured glass that allow light to pass through onto a flat solar cell. Brilliant!

Bloomberg Technology

It’s official: After Tesla shareholders approved the acquisition of SolarCity, the new company is now an unequivocal sun-to-vehicle energy firm. And Chief Executive Officer Elon Musk didn’t take long to make his first big announcement as head of this new enterprise. 
Minutes after shareholders approved the deal—about 85 percent of them voted yes—Musk told the crowd that he had just returned from a meeting with his new solar engineering team. Tesla’s new solar roof product, he proclaimed, will actually cost less to manufacture and install than a traditional roof—even before savings from the power bill. “Electricity,” Musk said, “is just a bonus.”
If Musk’s claims prove true, this could be a real turning point in the evolution of solar power. The rooftop shingles he unveiled just a few weeks ago are something to behold: They’re made of textured glass and are virtually indistinguishable from high-end roofing products. They also transform light into power for your home and your electric car.

Mexico Goes Greener

Mexico to Replace Oil Power Plant With Latin America’s Largest Solar Farm

By Ari Phillips
Last week President Obama and Canadian Prime Minister Stephen Harper visited Mexico for what’s traditionally called the “Three Amigos” meeting. In the daylong rendezvous, energy issues were slated to play a major role, with Obama and Harper jockeying for room when it comes to the impending decision on the controversial Keystone XL pipeline that would bring dirty crude oil down from Canada to refineries on the Gulf Coast.
However, Mexico also has some major energy changes in the pipeline, and after decades of state-run oil company PEMEX having sole purview over fossil fuel extraction, international investment and companies will now be let into the mix after recent constitutional reforms. This will increase oil flows from America’s southern neighbor into those same Gulf refineries as Keystone XL might. At the same time renewable energy has started to take off in Mexico, with construction of the biggest solar power plant in Latin America, Aura Solar I—a 30-megawatt solar farm in La Paz, Mexico—the latest signal.

IBM Creates Solar Panel To Power The Planet

IBM Solar Collector Magnifies Sun By 2000X – These Could Provide Power To The Entire Planet


According to Greenpeace, this technology can establish itself as the third largest player in the sustainable power generation industry. A study published in 2009 predicted that solar power could supply all the world’s energy needs, with minimal space. Greenpeace estimates that it would take only two percent of the Sahara Desert’s land area to supply the entire planet’s electricity needs.

DIY Solar Can Save You Money!

You Can Install Your Own Solar And Save Yourself Money

This is an informative article from Mother Earth News about one family's initiative to install their own solar panel system. Check out the tips on rebates and the state incentives database.




Have you been thinking about installing solar panels for your home, but been discouraged because the cost is too high? Here in Montana, my family and I saved 40 percent on the cost of a solar electric system by buying a kit and doing the installation ourselves.

One notable feature of our solar power system is that it uses the relatively new micro-inverter technology. With this system, each photovoltaic (PV) panel has its own grid-tied inverter that is mounted right by the panel. This kind of system is easier for do-it-yourselfers to install, and has other advantages, such as less sensitivity to partial shading, power output optimization for each PV panel, and the flexibility to start small and grow the system as time and budget allow.
We decided to go with a grid-tied system, which is much more cost effective than an off-grid system. One advantage is that you don’t have to buy batteries, which are expensive and have to be replaced from time to time. You can also choose to install a smaller, less expensive system that generates just a portion of your electricity. On the downside, grid-tied systems provide no electricity when the power grid is down.

Planning the Solar Electric System

The first step to planning your system is to evaluate rebate options and obtain permits. Your local power utility has rules you must follow when you hook the finished system to the grid, and building codes may also apply. In addition to federal incentives, states (and even some cities) offer rebates to help with the cost of the system. Most utilities will have an information package and a person who specializes in the utility requirements. We found our local utility and code inspectors helpful and friendly. We didn’t pick up a hint of resistance from them regarding the idea of a homeowner-installed PV system. Permit costs and turnaround times were small. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) for information on rebates in your state.

Solar Panels That Look Good!


Don't want those unsightly Solar Panels on your home? 

Here's an idea for some Solar style!

and science breakthroughs -- updated daily

New Solar Panels Made With More Common Metals Could Be Cheaper and More Sustainable

ScienceDaily (Aug. 21, 2012) — With enough sunlight falling on home roofs to supply at least half of America's electricity, scientists today described advances toward the less-expensive solar energy technology needed to roof many of those homes with shingles that generate electricity.





Shingles that generate electricity from the sun, and can be installed like traditional roofing, already are a commercial reality. But the advance ― a new world performance record for solar cells made with "earth-abundant" materials ― could make them more affordable and ease the integration of photovoltaics into other parts of buildings, the scientists said.
Their report was part of a symposium on sustainability at the 244thNational Meeting & Exposition of the American Chemical Society, the world's largest scientific society, being held in Philadelphia this week. Abstracts of other presentations appear below.
"Sustainability involves developing technology that can be productive over the long-term, using resources in ways that meet today's needs without jeopardizing the ability of future generations to meet their needs," said Harry A. Atwater, Ph.D., one of the speakers. "That's exactly what we are doing with these new solar-energy conversion devices."

Solar Panels are available now that look just like roof tiles. We have enough roof space to power our nation right now!  Everyone, wake up and take control of your own power needs. The "powers that be" need not take your money!
