We recently completed a 4 kW ground mount solar installation in upstate NY. The homeowners came back to groSolar after a successful roof mount PV installation 2 years ago.
Creating a clean energy future will require a lot of innovation and people taking responsibility. All summer I’ve been working toward three goals: clearing trees to enable a PV system on my roof’; putting in a large garden; and building an experimental hot-water system by collecting heat from composting wood-chips.
The “Brown Mound” is a densely packed mound of wood chips, with 400 feet of water line coiled throughout. As the chips decompose, the anaerobic bacterial process puts out heat. Anyone with a compost pile will tell you that if you stir it up, even in the winter, you’ll see a lot of steam.
So with that in mind, and some research I did on a frenchman named Jean Pain, we created our own version of a compost-powered-water-heater.
And, it’s working! We’re getting 1-gallon per minute of 95-degree water from the system, only 2 weeks after it was built. The temp should increase to 120+ as the composting process kicks into high gear. This should mean we burn very little propane to heat our domestic hot water, and we might even be able to heat the house a little by cycling the water from the mound through a radiant-floor loop.
The video below is a “making of” that shows how we build the mound, with the help of lots of friends and people involved in the Carbon Shredder organization. (Carbon Shredders are also co-sponsoring the KickGas Festival with groSolar in San Diego which includes a solar-power sweepstakes/drawing on Oct 24).
We’re really excited about a new solar module brand that we are offering. We searched high and low and met with module manufacturers all over the world in order to find a PV module that offers the performance, quality and price that you expect from groSolar. We’re happy to announce that we are bringing you modules from Canadian Solar. We’re able to offer you more watts per dollar, high quality and ease of installation at a great price.
A few of the reasons why we chose Canadian Solar:
Well established supplier with over 600 MW of module manufacturing capacity and has a well established track record for the commercial and residential PPA market
World-renowned technical expertise
Modules have uncompromising quality, durability, performance and value
Commitment to product innovations with high quality standards and sustainable business practices
Fully complying to IEC, TUV, UL international quality standards
Lowest power tolerance of any imported module: +/-2.1% – CSI stands behind their power ratings
Industry leading 6 years product warranty and 25 years performance warranty
Strong framed module, passing the mechanical load test of 113 PSF versus 50.2 PSF for most other manufacturers.(113 PSF is equivalent to withstanding over 212 mph wind speeds.)
We’re currently offering the CS5P (230 watt module) and the CS6P (200 watt module).
We have been very lucky to work with a local DC cooperative that is working to help their neighborhood go solar by making it convenient and affordable for everyone in their neighborhood. The Mt. Pleasant Solar Cooperative is an association of 70-plus households in the Mt. Pleasant community of the District of Columbia. They were founded because of the urgent need they felt to reduce their impact on global warming. They decided to use the coop model for two reasons. First, they decided that if they were going to go through all the work to figure out how to install solar technology, they realized they would have a bigger impact by including more people in the project. Second, they needed a way to make solar power less expensive and thought that through bulk purchase and sharing expertise and expenses they could bring down the cost.
Their immediate goal is to satisfy the solar needs of their neighborhood and ultimately to develop a model that can be rolled out in neighborhoods across the country.
The Mt. Pleasant Coop held an open house on Saturday, September 19th to show the public the success of this program. Check out some of the photos below and see the link to the news story here.
