- Q: Hello, I am shopping for solar panels for my home and there are so many to choose from. My house uses 40 Kw of power a day. If you had to choose from the output power of a solar panel from below, which one would you choose and why would you choose it? 2 Volts 4 Amps 48Watts2 Volts 8.5 Amps 02Watts6 Volts 7 Amps 2Watts24 Volts 4.2 Amps 00.8Watts24 Volts 8 Amps 95Watts
- There is more to sizing a system than simply selecting panels. I would suggest that you contact a solar installer to do a bid on your system. The quote should be free, and you can always say no. If a house used 40 kWh per day in our area, that would suggest a 6 kW array to offset substantially all the energy usage over the course of a year. Serious panels tend to be in the neighborhood of 200 watts nowadays, and that would mean 30 of those. You could size the system smaller, of course, if you wanted to offset a smaller percentage of your electricity. If there is any way that you can reduce the energy requirments, that will save you more money than putting in big solar. For example, if you can cut that in half by adding insulation and more efficient appliances, you will save more money than if you got a big array to power everything as-is.
- Q: 200 watt solar panel generates how much watts of electricity per month?
- I've operated a 25 kilowatt (kw) solar panel system for two years (44 panels, rated at 90 watts each, just about like yours). It averages 0 kilowatt hours (kwh) per day, but clear days get about 60 kwh. My system generates about 3300 kwh per month (we dump directly to grid), worth about $4,000 per year. Payback for my system, which cost $00,000 (after utility rebates and tax credits), is 25 years (the expected lifetime, coincidentally). Under similar conditions, your 200 watt solar panel would average 820 watt-hours per day, or about 25 kwh per month, worth $2.50.
- Q: I need to build a battery array to use with my solar panels I just bought. I want to be able to store enough energy to be draw from it at night, possibly around the clock. Is there a down side to using the deep cycle battery I bought from autozone and 6 or 7 more just like it, or do I need to get some other battery?
- There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
- Q: Can solar panels be installed on water treatment plants or utilities?
- Yes, solar panels can be installed on water treatment plants or utilities. In fact, many water treatment plants and utilities have started to adopt solar energy as a sustainable and cost-effective solution to power their operations. Solar panels can be installed on the rooftops or open areas of these facilities, helping to generate clean electricity and reduce their carbon footprint.
- Q: My project needs to build a thermal solar panel that would be used as a demonstrational rig. The dimensions i am allowed do not allow me to use a normal thermal solar panel so i have decided to use the heat exchanger from the back of a fridge. Although this is possible to use what equation would i use to prove the power of the sun would actually heat up the water. More importantly when the rig is demonstrated to students, they will need to be able to determine if the raise in temperature given by the thermometers is what should be given. Variables of the rig will include: Angle of the panel, Light intensity, Direction of panel, and more importantly the flow rate of the water travelling through the pipes. What equation includes those variables (change in temperature, flow rate) and would allow me to incorporate the angle of the panel. The light source would be a lamp so i would also need to know how much of the energy from the lamp is actually being used by the panel?
- Forget the long winded discussion above. There are so many variables that you cannot calculate the outcome. This does not mean that the experiment is a failure. It gives you information on the fact that water can be heated in this manner, and that you can vary the result by modifying the variables.
- Q: I want to buy a solar panel kit to run my central AC unit. it is a 3 ton unit. Can I do this? The electric rates in the Chicago area are skyrocketing and I can't keep paying 350 dollar electric bills during the spring and summer months
- It sounds like saving money is your chief goal. If your house is not already super-insulated, that should be the first target. Super-insulation, radiant barriers, double-pane windows, white roof, weatherstripping, attic fan. Number two would be conservation. Can you turn the A/C up to 80? I visited a place in Wyoming when it was 0 outside, and 80 felt very pleasant. Third, efficiency. Have you considered a ground-sourced heat pump? Deep down below your house the water table may be colder than 40 degrees F, and can provide good cooling. After all that, you can look into solar electric, which may or may not be a good deal in your area. The type of solar electric that is most cost efficient is the kind that connects right to the house wiring and works alongside the normal electric company. You can talk with a local installer and get a free financial analysis. Then you can look at it and see if the installer is on the level, or trying to play accounting tricks with unreasonable assumptions. Solar makes sense in most parts of California, but Illinois is not known as a big solar area. The kits you have have seen were probably for standalone solar, generally an expensive proposition for the amount of power you get. Put another way, either it will be low power, or it will be very expensive.
- Q: How does the size of a solar panel affect its performance?
- The size of a solar panel directly affects its performance as a larger panel can capture more sunlight and generate a higher amount of electricity. A larger surface area allows for more solar cells to be integrated, resulting in increased energy production. Additionally, a larger panel can accommodate more efficient components and have a lower resistance, leading to improved overall performance.
- Q: how to market solar energy products?
- It depends upon your product. If it is a solar panel, I want to know if it is a photovoltaic panel or a thermal panel. If you don't know enough to know the difference for your question it might be somewhat difficult to suggest others should buy them. Products have to be marketed to a need either already felt or not so apparent. Photovoltaic panels supply an electric need and will offset electrical usage or may supply the grid if there is excess power. A discussion of payback periods including property values will be needed in any event. Thermal panels supply heat and hot water. They are more efficient than photovoltaic panels and will give faster payback times. (are cheaper) If you are a bit more specific more information may be possible.
- Q: Is this true in a dc system? What if my battery current is negative?
- I am not sure about your question ? If your Q is, what is the solar panels current output, it is 8.73A regardless of the load. If the Q is, How much extra current is available in this circuit, the answer is 3.58A ( 8.73 - 4.32-.83= 3.58)
