The Sun Rises on Solar Power
|
Bronze Member Username: Kent_island50Post Number: 100 Registered: Mar-11 | The price of solar electric systems has fallen rapidly in recent years, making solar energy more accessible than ever. In 2010, the installed cost of residential and commercial solar photovoltaic power systems fell by 17 percent from the previous year, falling an additional 11 percent in the first half of 2011, according to a report by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab). So is now the time to take the plunge? Well, such statistics don't mean that solar power systems are cheap. The average cost nationwide last year was $6.20 per watt, says Ryan Wiser, a Berkeley Lab scientist. An average-size home (about 2,000 square feet) generally requires a 5-kilowatt system -- approximately a $31,000 investment. "There's a large up-front cost, but there's also economies of scale," Wiser says. "The cost per unit on a smaller system will be higher." So if you opt for more power -- say, a 10-kilowatt system -- the price per watt will be substantially lower. Your circumstances could also help: It's cheaper to install a system on new construction versus an existing home. A Consumer's Guide http://www.nrel.gov/docs/fy04osti/35297.pdf |

Diamond Member Username: NydasPost Number: 22546 Registered: Jun-06 | Are you kidding? 45 Watt Solar Panel Kit claiming to power computer, TV, etc. A desktop computer requires over 120 watts as a bare minimum. Even a 22" TV requires at least 80 watt and more like 120 watts of power, and most people have at least a 32" TV |

Diamond Member Username: WingmanaliveWww.stainles... .ecrater.com Post Number: 25306 Registered: Jun-06 | The output of any off grid solar system is directly related to the size of the battery bank. 45 watts in panels is tiny indeed and would take several days if not longer to charge a battery bank that could power items like a tv or computer. Just like in automobile electrical systems there is no substitution for production. You CAN, however, do this. The battery bank is there to supply the constant voltage to the inverter, which provides power to your devices at the correct voltage. It's inevitable however that if your consumption of power exceeds your production then your devices will fail eventually and you risk damaging your batteries if they are not deep cycle. Small systems like those are for shed lights or small outdoor landscaping lighting. I used to have a small solar setup that I used sparingly to power my 52" tv among other appliances. My bank was a modest 210 amp hour system initially built as an experiment. It worked. I used the same HF 45w kit and purchased an additional charge controller and system monitor because the gear they supply is almost garbage. What you're really after is the panels anyway. Connected a 2000w inverter to the bank and after several days of sun I was able to harness enough power stored in the bank to run my tv for a couple hours. Ideally I would have liked 200w in panels but as an experiment I wasn't going to drop THAT kinda $$ just yet. Many people use small stand alone systems for remote locations like out buildings in a barn or a cabin in the mountains. Just where you need to run something large infrequently or something small all the time. With the price of solar panels about half what they were just 10 years ago it's a good time to look into it. Typically the smaller the panel the more you'll pay per watt. Stay away from panels that are costing $4/watt or more. Search around enough and you can find them from wholesalers for $3/watt or less. I laugh when I see a 5w trickle charger for $50. $10/watt is insane. |

There are arrangements for the Utility company to buy your generated power, so you can have s a smooth supply. A system that will meet your electricity needs up to 40% seems feasible |

Diamond Member Username: WingmanaliveWww.stainles... .ecrater.com Post Number: 25308 Registered: Jun-06 | Subsidies and federal and state rebate programs may still be alive but for the most part are getting sucked up and dried out due to insufficient funds. Plus the money isn't instant which means the cost of the install will fall directly on the homeowner. Add in the required new roof costs, which, depending on the size of your roof, can be anywhere from an additional $3500 to $10,000, and you have a very substantial investment staring you right in the eyes. Grid tie systems are financially viable in the long run but you HAVE to consider the initial costs and also routine maintenance. Areas with snow will mean frequent snow removal which all but eliminates productivity of the panels. Off grid? Remember those batteries often carry the same lifespan as car batteries and will frequently need swapped out every so many years. That alone can be a $2000 "tune up". The panels themselves are generally good for 25+ years so as long as your installer is up to par with his techniques your attention will mainly be focused on just keeping them clear of debris. You also NEVER want to consider a ground install, unless you live inside a gated and monitored property lol. Solar panels are fast becoming one of the hottest stolen items, mainly due to their lightweight and "price per pound" worth. A $900 panel can be carried by a 7 year old. Even panels on highway call stations are missing. Thieves will stop at nothing to make a $! |

Diamond Member Username: NydasPost Number: 22552 Registered: Jun-06 | You forgot to add the added cost of insurance. If these panels are likely to get stolen, the insurance company will charge more for insurance. The technology is still in its infancy as far as a normal home-owner is concerned. Subash: I know of the Ontario government plan, but how many are actually using the incentive? |

Platinum Member Username: LklivesPost Number: 16830 Registered: Jan-06 | I have a new solar system on my roof...7 panels...heats my house hot water and my pool,,,..all for less than $3000...if ya look around ya can make it happen inexpensively.. |

Diamond Member Username: NydasPost Number: 22554 Registered: Jun-06 | That translates to an amortization in 10 years at the rate of about $30 per month. Not a bad bargain at all for heating the pool and hot water for the house. |

While perhaps best known in a residential setting to provide domestic hot water, solar hot water also has industrial applications, e.g. to generate electricity.[1] Designs suitable for hot climates can be much simpler and cheaper, and can be considered an appropriate technology for these places. The global solar thermal market is dominated by China, Europe, Japan and India. A solar hot water heater installed on a house in Belgium In order to heat water using solar energy, a collector, often fastened to a roof or a wall facing the sun, heats working fluid that is either pumped (active system) or driven by natural convection (passive system) through it. The collector could be made of a simple glass topped insulated box with a flat solar absorber made of sheet metal attached to copper pipes and painted black, or a set of metal tubes surrounded by an evacuated (near vacuum) glass cylinder. In industrial cases a parabolic mirror can concentrate sunlight on the tube. Heat is stored in a hot water storage tank. The volume of this tank needs to be larger with solar heating systems in order to allow for bad weather, and because the optimum final temperature for the solar collector is lower than a typical immersion or combustion heater. The heat transfer fluid (HTF) for the absorber may be the hot water from the tank, but more commonly (at least in active systems) is a separate loop of fluid containing anti-freeze and a corrosion inhibitor which delivers heat to the tank through a heat exchanger (commonly a coil of copper tubing within the tank). Another lower-maintenance concept is the 'drain-back': no anti-freeze is required; instead all the piping is sloped to cause water to drain back to the tank. The tank is not pressurized and is open to atmospheric pressure. As soon as the pump shuts off, flow reverses and the pipes are empty before freezing could occur. Residential solar thermal installations fall into two groups: passive (sometimes called "compact") and active (sometimes called "pumped") systems. Both typically include an auxiliary energy source (electric heating element or connection to a gas or fuel oil central heating system) that is activated when the water in the tank falls below a minimum temperature setting such as 55 °C. Hence, hot water is always available. The combination of solar water heating and using the back-up heat from a wood stove chimney to heat water[2] can enable a hot water system to work all year round in cooler climates, without the supplemental heat requirement of a solar water heating system being met with fossil fuels or electricity. When a solar water heating and hot-water central heating system are used in conjunction, solar heat will either be concentrated in a pre-heating tank that feeds into the tank heated by the central heating, or the solar heat exchanger will replace the lower heating element and the upper element will remain in place to provide for any heating that solar cannot provide. However, the primary need for central heating is at night and in winter when solar gain is lower. Therefore, solar water heating for washing and bathing is often a better application than central heating because supply and demand are better matched. In many climates, a solar hot water system can provide up to 85% of domestic hot water energy. This can include domestic non-electric concentrating solar thermal systems. In many northern European countries, combined hot water and space heating systems (solar combisystems) are used to provide 15 to 25% of home heating energy.  |

Bronze Member Username: Tommy_hPost Number: 37 Registered: Jan-12 | "I was responding to Paul's statement "Solar panels are fast becoming one of the hottest stolen items, mainly due to their lightweight and "price per pound" worth. " You are talking about your average back yard solar panels for pools and such bought at Wal-Mart. Larger panels are different all together and not that easily taken down or easy to just walk away with without anyone noticing you. |

Platinum Member Username: LklivesPost Number: 16831 Registered: Jan-06 | The rubberized panels are 4x10 and are actually very light, about 10-20 pounds each...and under $200 each, depending on which brand and warranty ones ya buy, but cannot be bought at Walmart..then all ya really need is PVC piping and a few relief valves, hoses and clamps, with a thermostat for a home hot water system and pool use...and just simply tap into your existing water heater that will kick on electrically (heat element) when there's not enough sun to heat the water or if ya use it all up too soon. ...but I don't think anybody will be throwing a ladder up to my roof and climbing there to steal them.. Geronmo..U have the right idea.. |

Bronze Member Username: Tommy_hPost Number: 42 Registered: Jan-12 | Nydas your posts are contradictory to say the least. In one thread you inforce or warn about the laws and in others you break those same laws by giving information to use IKs which is very illegal. What side are you one? Same goes for this subash character. He calls everyone a crook, but at the same time posts the same kind of information regarding how to use IKS. |

Diamond Member Username: NydasPost Number: 22566 Registered: Jun-06 | tommyhesaw: The only posts I have made in this thread are related to Solar panels. There have been a few interruptions by others and a comment by you which should have been addressed to Paul not me. If any of the interruptions were made by you in another name, than comment in that name. |
