Solar power install with deer: pole-mounted PV array
pole-mount (ground-mount) solar PV system, what it looks like during construction, and some information on the wiring and solar in general.
All solar PV panels generate Direct Current (”DC”) in the daylight, converting the energy of the sun into the movement of electrons. DC current is like a cattle drive, where all the electrons are moving in one direction, to the load, then they move back to the source. Thus, DC current is one steady flow of energy born by electrons in motion.
The DC power goes to an integral DC cutoff, which enables electricians to cut off the flow of DC power TO the inverter when servicing it. This DC power is the most pure you can imagine, it’s great for welding, and you can easily strike an arc with it. These high-voltage inverters run at about 400v, and generate about 5 kW, or about 12 amps to use if you wanted to weld with it. I’ve struck an arc with DC from a 80v 3 kW system, which had thus about 40 amps.
The DC power goes into the INVERTER, which changes it to standard house current (Alternating Current, or AC). AC current is like a long line of cows doing the Texas Two Step, one step forward, one step back. AC is best for power transmission, but almost all household appliances use DC via internal inverters. Ironically, almost all appliances could run off the DC power from solar panels, the solar system inverter turns it into AC then the appliance turns it back to DC again.
From the inverter the AC power goes to the AC cutoff and the performance meter, which gives a double-check on how much power the solar system produces.
This “grid-tied” system operates like a stream flowing into a river — it just merges with the utility power, filling up the house first, then, if there’s an excess, running the main meter backward and helping the utility meet peak demand.
A battery-backup system runs exactly the same if the grid is up; but the inverter is a different model. Power flows into and then out of the battery-backup inverter; but if the power in fails, or is out of proper range, the inverter (like the grid-tie) islands from the grid. But the battery backup inverter goes to its battery pack, and continues supplying power out to the load based on the batteries. Of course, if you, as I do, have a solar system, the solar refreshes the batteries on the next sunny day, and you can just go on indefinitely, really “off the grid”. The battery backup inverter is smart enough to start and use a generator, if you don’t have a solar system. Really, installing a battery-backup doesn’t require a solar system, it’s just a wiring thing, and doesn’t even go into your home wiring.
Pole-mounted systems lose the advantage of roof-mounted systems which actually cool the house, lowering the need for air conditioning. Under the panels, it’s shade, and it protects the rooftop.
These holes had to be 48″ deep, and were filled by 3.5 yards of 5-bag concrete delivered to each hole by a cement truck. The system was wired up according to the prepared Wiring Plan, inspected and approved less than one week later, and is now in operation.
The company is EESolar, Energy Efficiency Solar, of Pomona, CA.

The Battery 500 Project
The Battery 500 Project: The Future of Electric Vehicles from http://asmarterplanet.com.
Today, a vast majority of the worlds oil is burned for transportation. Energy sources such as wind, geothermal and solar power, fluctuate continuously and can do little to reduce oil consumption unless the energy produced can be harnessed and stored.
Many experts believe the solution may lie in the development of an efficient, affordable energy storage network. Simply stated, energy storage not energy generation is seen as an important step toward the future.
A key part of current electric energy storage research will be influenced by the work of a consortium that hopes to develop next generation lithium batteries able to power electric vehicles for 300 to 500 miles on a single charge. This research may uncover major advances in larger-scale power storage for future electric grid applications. This next-generation battery is called Lithium-air.
In this video, experts from talk about the research and development behind Lithium-air and why they feel it may represent the future of energy storage for electric vehicles.

Rahimafrooz Batteries Ltd, Bangladesh, Solar home systems – Ashden Award winner
This video can be downloaded here: http://www.ashdenawards.org/winners/rahimafrooz Rahimafrooz Batteries won an Ashden Award for Sustainable Energy in 2006. To find out more visit the link above and check out the Ashden Awards Blog http://ashdenawards.blogspot.com
Rahimafrooz Batteries Ltd has played a leading role in the Rural Electrification and Renewable Energy Development Project (REREDP) – a large scale programme to provide solar home systems (SHS) to rural households in Bangladesh. Rahimafrooz has manufactured and supplied the rechargeable batteries for over 75,000 systems, as well as charge controllers and fluorescent lamps. Rahimafrooz has also exported over 80,000 batteries for PV systems, mostly to Nepal and Bhutan.
Nearly 70% of households in Bangladesh are not connected to the electricity grid and so depend on kerosene for lighting. This includes most rural areas, and also the fringes of Dhaka. There are plans to extend the grid, but there is little prospect of substantial change in the near future. The REREDP, which is funded by the World Bank and GEF and managed by the Infrastructure Development Company Limited (IDCOL), initially aimed to provide 50,000 systems by the end of 2007, but this has already been increased to 200,000 systems because of the success of the programme, and may be further increased. IDCOL provides Participating Organisations (POs) in the programme with subsidies and concessional loans to purchase PV systems in bulk, and the partners can then provide credit to rural households to buy systems. PV electricity can have a huge impact on people’s lives, providing power for lighting, phone charging, education and entertainment.
One reason for the success of the project is the local availability of components from the manufacturing and development work of Rahimafrooz. The company has applied its considerable expertise in battery manufacture to the production of batteries specifically for PV systems, as well as diversifying into the design of charge controllers and fluorescent lamps for local manufacture. Rahimafrooz has also supplied 25,000 complete SHSs, mostly for IDCOL POs under the REREDP, and has provided training and technical support for these POs. Outside the REREDP, Rahimafrooz has installed 448 kWp of other PV systems.

Converting a battery powered fan to a Solar Powered Fan
I searched high and low for a solar powered fan but with no joy so i bought a battery powered fan and two rechargeable batteries, i used my solar power battery charger (for the same type batteries) and connected the wires to a plug.
I modified the socket inside to the power goes directly to the batteries. So not to burn out the motor if you do this yourself it’s a good idea to reduce the power to the fan at the same time as using solar power to charge the batteries.
It works a treat. I made it for someone special.
Cost…. $4 for wire and plug. 20 mins to solder the wires inside the fan and modify the solar battery charger.
