Solar powered pyramid
by WRETHAOFFGRID on OCTOBER 27, 2013 - 2 Comments in OFF-GRID 101, SOLAR, WRETHA

Pyramid power

Ever see an off grid pyramid? Well you are about to. This is the video story of Greg Grant, who began his off grid existence slow and small.

He didn’t put a lot of money into his project. What he had was land, lots of natural materials, a great bunch of talented and helpful friends, and a unique vision. He chose to make his off grid home out of short straw-bale walls, but with a steeply pitched, pyramid shaped roof. (more…)

Solar Charge Controllers
by NICK ROSEN on AUGUST 8, 2012 - 6 Comments in OFF-GRID 101

If you have a simple off-grid setup with just one panel or even a few solar panels and several batteries, the other vital ingredient is a charge controller that regulates the power going from the panel to the battery and shuts off power input when the batteries are fully charged.

This makes the process of running your own power station almost maintenance free.

When you are starting up its best to buy a medium-priced controller so that you can add a few panels and batteries to the mix before having to upgrade. The HQRP 20A Solar Panel Battery Charge Controller / Regulator 12V / 24V 20 Amp 300W with PWM Type of Charging retails at under $50 on Amazon.

Don’t believe the hype

Solar newbies beware

Don’t believe the awful ads which promise you “free power for $200″, or “build your own solar panel for $200″. Several of them appear on this site from time to time, despite that we are doing everything we can to stop them.  Many are from Chinese spammers, and a particular bunch of conmen called energy4free, or earth4energy or, amongst many other aliases. These slimebags ask you to pay for an e-book which directs you to some other sites and offers to sell you components for a solar panel that will never work. Of course it would be quite wrong and immoral to suggest you should click repeatedly on their ads whenever you see the Earth4energy logo. We do not recommend that. (more…)

Solar cheaper than grid within 3 years
by AMY SUAREZ on DECEMBER 8, 2011 - 1 Comment in SOLAR

David CraneThe head of one of America’s biggest Utility companies has forecast that it will soon be cheaper to harvest energy from your roof rather than from the grid.

David Crane, the CEO of NRG Energy, is not your typical power company executive, as becomes clear from his interview with a Yale University  student magazine, e360.

NRG is a Fortune 500 company producing electricity for up to 20 million U.S. households. Crane is still neck-deep in hydrocarbons, with more than 90 percent of NRG’s electricity production coming from natural gas, coal, and oil. Crane  believes the electricity market is about to be transformed by the widespread adoption of solar panels on residential and commercial roofs, and electric cars in garages, (more…)

Grid can’t handle mass solar
by AMY SUAREZ on DECEMBER 3, 2011 - 1 Comment in SOLAR

Utilities can't handle universal solar

Further evidence in favor of Micro-grids and against the so-called Smart Grid.

The runaway take-up of rooftop solar panels in Australia has undermined the electricity supply system, feeding so much power back into the network that it is causing voltage rises that could damage household devices such as computers and televisions. This means we should either rewire every home and every street, to suit the convenience of the big Utility companies, or rethink the way the nation’s energy delivery is organised. What applies to Australia is true elsewhere in the world. (more…)

building solar panels and loving it ;’)
by FARIAN on JUNE 2, 2011 - 4 Comments in I WANT TO GO OFF GRID

i’ve built 4 x 65 watt panels from scratch ;’).. i’m doing free energy experiments, but i also want to get a system sorted for people to get there low powered stuff / battery powered stuff off grid, i.e. not many people can get 100% off grid because of costs, so getting 50% of appliances 100% off grid is a bonus , isn’t it, LOL i’d thinking of land in Bulgaria.. its dirt cheap with run down houses etc… ideallly would love to be in a ‘freeman’ community…
reclaim land or something…. One Love ;’).

Can solar crash the grid?
by ALEXBENADY on OCTOBER 29, 2010 - 1 Comment in SOLAR

Solar peaks can swamp the system

Its obvious that renewable energy has the potential to undermine the grid’s grip on our lives. But that’s mostly an ideological thing. Until this week no-one suspected that renewable energy could cause real physical damage to national power infrastructures.

According to the Berliner Zeitung, the head of Germany’s energy agency DENA is warning that there is a real danger that solar power, could crash Gemany’s ageing electricity grid. (more…)

New Jersey solar incentives the best in US
by NICK ROSEN on JUNE 13, 2010 - 1 Comment in SOLAR

Solar Garden State

New Jersey is the sunniest state in America, offering solar energy incentives for residential systems that can pay for themselves in as little as three years.
The state is second only to California in the number of homes outfitted with solar technology, drawing so many applicants for generous rebates in May that the Board of Public Utilities has put new requests on hold.
New Jersey is the only state to mandate a Solar Alternative Compliance Payment, essentially a penalty a utility must pay if the company does not reach its SREC target. To make that goal, utilities buy these green-energy credits from consumers and businesses. (more…)
Green Party attack central power
by ALEXBENADY on APRIL 17, 2010 - 2 Comments in EVENTS

Green Queen LucasThe UK Green Party manifesto for the upcoming general election explicitly attacks the idea of centralised power and  promises to take from the rich and give to the poor.

Speaking before the launch of the manifesto, Green Party leader Caroline Lucas (pictured) promised a “signifcant increase in decentralised energy.” Arguing against the inefficiencies of the grid she said, “many centralised power station waste as much of two thirds of their energy in heat through their cooling towers and in distribution losses.” (more…)
