Q:Does anyone know how I would go about hooking up the air conditioners in my house to solar panels? I would want just the air conditioners to be powered by solar energy. How could I hook it up where the panels can absorb energy from the sun during the day, and save and store the energy so I can run the air conditioners at night? I really feel that in the long run, this would save a lot of money with the energy bill. It's the use of the air conditioners that drive up the bill. Is this idea feasible? Is it also possible to have some sort of hybrid system where I can switch from solar to my regular local energy source when I want to?

There's no need to connect only the A/C to solar, nor is there a need to use batteries. Both of those problems are solved with grid-tied solar. The solar electricity system works alongside your regular, and the A/C just plugs in normally. You never need to worry about switching. During the day, if the A/C is drawing power, the solar goes into that, reducing your draw from the electric company. If the solar generates more than the A/C needs, the meter is driven backwards. At night, the meter runs forward again. For example, the meter may read 5000 in the morning. By evening, maybe it reads 4975. At night, it creeps back up to 5005. When the meter reader comes, you would be billed for only 5 kWh. That's the general idea. Also, consider whether you can insulate your home more, and whether you might want to change out your air conditioners for new, DC inverter mini-split units. Those can use a fraction of the electricity per BTU of regular air conditioners.

Q:Can solar panels be used to power an entire office building?

Yes, solar panels can be used to power an entire office building. With proper planning and installation, a sufficient number of solar panels can generate enough electricity to meet the energy needs of an office building throughout the day. This can significantly reduce or even eliminate the reliance on traditional energy sources, leading to cost savings and environmental benefits.

Q:I need a list of worldwide solar panel manufactures from china, US, Spain, Germany, Japan etc...Can any one direct ne to such place?I rather it will also contain comparison of parameters like efficiacy, quality etc and to be divedied by country of manufacturing.Thank you

Actually Ofir, it is much easier and less expensive than you might believe. What you need is a magazine, like, Solar Today. There is only one that I am familiar with that gets into the nuts and bolts of solar panel manufacturers, installation, and other types of renewable energy. It's called, Home Power Magazine. We have a home that has been powered by the wind and sun for the last 0 years or so, and most of our initial information came from Home Power, and afterward, from many of the sources that they have in their articles. Every few issures, they take an item connected to renewable energy, such as an inverter, wind turbine, water turbine, or solar panel, and list all the different models that are available. They are broken down by manufacturer, and include specifications like power output, range of voltages, efficiency, materials, and even where they are manufactured. If you subscribe online for one year, the cost is around $25 USD, you will have access to all the previous issues that are archived on their website. You can use their search engine to locate an article listing all the solar panels, they did one a year or so ago with all the information you are looking for. Despite what you might be hearing, solar power usage is growing at an incredible rate. In the US alone, there are over 00,000 homes and businesses operating some level of solar power right now, that's good news. As far as different countries using different requirements, most all of the manufacturers today are selling their products to most countries worldwide, they are designed to meet requirements for almost anyplace you might use them. Check the magazine out today, you might learn more than you were originally looking for. I will include their link below, and some other good sources for information. You can google any one of them to find their website. Good luck, and take care...Rudydoo

Q:discription how does solar panels save energy

I'm definitely no expert in the field but hope to learn much more in the future. I'm in the infancy stage of researching as many options as possible in the design and construction of a total green house. That being said, a particular local news story sparked my interest when they investigated the cost effectiveness of residential solar panel systems. Here in Austin, Texas, through subsidies and incentives offered, you can install a system that costs roughly 22.5k for about 7. Apparently these deductions come from a federal incentive (which is a very small portion) combined with those set by the city itself. Austin is a pretty progressive city so I imagine their incentives might be a little better than most but you can call your city's general info line (3) and do a little more digging. Another option you might have is renting the equipment. I was told yesterday that a company here in town would allow for the installation and use for a monthly rate. I know how tight cash can be in school and 7 thousand might not be tangible. The whole issue of energy conservation is so prevalent these days that new info is constantly coming out. Give your current energy provider a call and see what they can tell ya. I hope you find something that works for you. -G

Q:Photo-Voltaic solar panels are very expensive. Most of a home's energy needs are for heating water, heating and air-conditioning. All of these can be met with thermal solar collectors which are much less expensive. The thermal solar panels would heat water stored in a hot water tank which then can be used as hot water, to heat the home, or as the heat source to a Lithium Bromide Absorption chiller to air-condition a home. With the base line needs met without expensive panels and without inefficient energy conversions, only a small Photo-Voltaic array would be needed for the remaining power needs and since those needs are variable, there would still be power to sell to the grid.

That sounds good to me. I'm all for any kind of new energy as long as it's renewable and doesn't pollute the environment. I'm even a fan of solar water heating.

Q:I don't have a regulator connected as they are a little expensive for a pensioner, If I join the panels into line to the battery bank from the roof should that be OK.?

Two things on a regulator: a) It will optimize the charge to the batteries - and thereby distribute the most possible power to your active circuits during the day. b) It will prevent the power from the panels from boiling (no kidding) the batteries - no small thing as they are the second largest investment you have after the panels themselves. This is much more critical if you have sealed or Zero-Maintenance batteries. I strongly suggest that you get a regulator as it will significantly lengthen battery life. Follow the directions on the regulator for optimum input voltage and it will let you know whether all the panels should be in series, parallel or series/parallel. But cutting to the chase, you can certainly gang up panels as needed.

Q:trees vs solar panels who would win?

If it was a physical battle, solar panels. It's like burning ants with a magnifying glass. Aim the solar panel at the trees and you have a forest fire.

Q:I need to know where I can buy the parts or find them as scrap to make my own solar panels. Is there a cheap way of buying the panels or can I make them myself.

Q:ASAP :) as much details as possible

As other sources of energy become more expensive due to declining rates of production, or increased costs for safety or pollution controls, solar energy becomes more practical as a method of gathering inexpensive supplemental energy. Look at the german experiment, where rooftops in germany were covered in solar panels and wired into the house system to supplement energy needs. In some places, I'm not sure about Germany, you can actually sell back surplus electrical energy to the power company if you have more capacity than you can store in the batteries attached to the panels. Keeping energy costs lower than they would otherwise be helps the economy by making growth less difficult for new and existing companies, and puts money in the hands of consumers that they otherwise would have had to spend on electricity. We need some additional innovations in battery technology and solar panels to make solar a mainstream source of energy, but replacing roofing with solar panels is a very interesting idea that might become a mainstream building practice if the cost of other kinds of energy keeps rising.

Q:How do solar panels affect the grid during times of high electricity demand?

Solar panels can help alleviate the strain on the grid during times of high electricity demand by generating clean and renewable energy. By producing electricity directly from sunlight, solar panels can contribute to the overall power supply and decrease the reliance on traditional fossil fuel sources. This reduces the burden on the grid, mitigates the risk of blackouts, and helps meet the increased energy demand more sustainably.
