- Q: Well I was thinking about the idea of renovating either a smaller school bus or building a tiny house and I was wondering if i can get some information on the size and watts panel should I use or more like how to get that whole solar energy in motion. Any infor and links would help
- I think that typical solar panels are 2'x4' and produce something like 800-000 wh per day. (That's 0.8 - kwh per day.) More in the summer, less in the winter, if they're aimed sort of at the sun. There are newer, more expensive panels that produce more. There are also thin film panels that are less expensive, and probably more sturdy. You then have a couple choices. In a house, you'd have an expensive inverter to connect to the utility power, so you can have power at night when your panels aren't generating anything. In a trailer, you want 2-4-6 deep cycle car batteries to store the power. Then you could have an inverter to convert that power to 20v AC, so you could use normal appliances. Or, you could buy appliances that run on 2 volts DC. Maybe a combination of both. You'll need to figure out how much power you're going to use, so you know how many panels and batteries you're going to need. The calculation is easy. Figuring out how much power you need is hard. You need deep cycle batteries because you can repeatedly charge them way up and run them way down. Ordinary batteries die fairly quickly when you do that.
- Q: Can solar panels be used in commercial buildings?
- Yes, solar panels can definitely be used in commercial buildings. In fact, many businesses are increasingly installing solar panels on their rooftops or in open spaces to generate clean and renewable energy. This helps reduce their reliance on traditional grid electricity and lowers their operational costs in the long run. Additionally, commercial buildings often have ample roof space, making them ideal for maximizing solar energy generation.
- Q: Can solar panels be used in areas with high humidity?
- Yes, solar panels can be used in areas with high humidity. While high humidity may affect the efficiency of solar panels to some extent, they can still generate electricity. The performance of solar panels in humid environments can be optimized by using materials that are resistant to moisture and by ensuring proper installation and maintenance.
- Q: Are there any limitations to the lifespan of solar panels?
- Yes, there are limitations to the lifespan of solar panels. While most solar panels are designed to last for several decades, their efficiency gradually decreases over time. Factors such as weather conditions, shading, and quality of materials can impact their lifespan. Additionally, some components, such as inverters, may need to be replaced after a certain period. However, with proper maintenance and regular inspections, the lifespan of solar panels can be maximized.
- Q: The average solar panel produces 0% of the energy that is put into it. What is happening to the other 90%? Is it being reflected or is it being obsorbed by materials that are not a part of the solar cell? Is it possible to one day have near 00% efficient solar cell technology?
- Mainly due to reflection (micro-structuring of the surface helps here), incorrect wavelength of the light (the panel is only sensitive to a certain wavelength range) and heating of the panel (due to the incident light/thermal radiation). The remainder is either reflected or absorbed by the cell and re-emitted as heat. Absorption by e.g. the glass panel is slight (a few %), as is absorption/reflection by the necessary surface contacts (again, a few %). Higher efficiency is possible, but brings its own drawbacks (like higher cost). You could now go into two directions: - high efficiency cells/panels with (likely) higher cost and complexity for mounting (like lens or mirror based systems, aka concentrator systems, that increase the light level on the cells in order to increase efficiency) - low cost systems (cheap as dirt) that will allow you to cover every surface of a building, efficiency is less important if you can compensate by a much larger covered area As to the efficiency limit: there is a theoretical limit (from thermodynamics - don't ask me how or why) in the range of 30...40%, depending on which publication you want to believe in.
- Q: I have a home in Manchester Tn and we have been slowly remodeling the home. It is about 200 sq ft of living space. Our normal electric bill is about 50 a month. We would like to add some solar panels to the home to help reduce the amount of the bill. How many panels do I need and what would be the cost? I am not trying to go completely of the grid but I would like to start somewhere and maybe over the years be able to add. What is your recommendation for a reasonable cost of under 2 to 3 k??
- Unless there has been some major breakthrough in solar panel efficiency - Forget it. I had looked at some utility interactive systems where the electricity generated by the solar panels went through a special inverter and into the electrical system of the house, any power you didn't use went backwards through the meter and into the grid. I figured that even if it was sunny every day, it would take about 20 years to break even on the system. That is, if I had invested $5,000 in a small system, to save $5,000 off the electric bill would take 20 years. If I had $5,000 to invest, this wouldnt be the place! It would take much more than 20 years of electrical savings to match even a modest investment. Then, don't forget what happens if 0 years from now the inverter or some of the panels fail and need replaced. Invest in fluorescent lights, maybe even LEDs. You will see a much quicker return on investment. Install more insulation, put in a heat-pump system. I appreciate you desire to save some energy, solar just isn't going to be worth doing, at least not yet.
- Q: If I put a 5000 watt solar panel kit on my roof in Dublin (Ireland) - how much electricity would I realistically expect to get?An educated guess at a percentage of 5000w would do.
- This is dependent on sun angle, clear sky, shadow interference, clouds, etc. First if you purchased the PV panels and they are rated for 5 kW, the factory rating is based on a particular incident energy, 000 watts/square meter, 25 degrees C and an AM of .5, reaching the panels. It is more likely that you will not obtain this same level in the open air. If we assume you will get 80%, then the maximum kW would be closer to 4kW. This will be produced during peak, clear days with the panels placed perpendicular to the sun at all times during peak radiance times. When the sun first comes up and later when it is going down, there will be more than the thickness of .5 atmospheres between you and the sun, so the radiant energy hitting the solar panels drops off. Total energy is watts time hours. I would expect you PV system to produce about 750 kW-Hr of energy during a clear summer day at peak solar height. Hope this helps, NewtonLaw
- Q: i have 2 questions.. I have a 6v solar panel, if i wanted to charge batteries with that it what batteries could i charge? Could charge normal AA batteries with it our do i need special batteries.2. I have a 6v solar panel that produces watt. I want to light a bulb with it but whenever i hook it up the solar panel won't light it up. I think the current of the solar panel is too low. How can i increase the current of the solar panel
- [] Use it to charge 4 pieces AA cell ( connect in series to make 5V battery pack ) for 0 to 4 hours. Good for cell rated 600mAH ,2000mAH,2500mAH. [2] Cannot increase current. Buy some more this panel and hook them together in parallel to increase current. You need at least ten pieces to make current reaches .6A to light up some 6V bulbs.
- Q: Can solar panels be used in areas with high levels of radiofrequency interference?
- Yes, solar panels can be used in areas with high levels of radiofrequency interference. However, it is important to note that radiofrequency interference may affect the performance of solar panels and reduce their efficiency. Proper shielding and grounding techniques can be employed to minimize the impact of radiofrequency interference on solar panel operations.
- Q: What is the maintenance cost of solar panels?
- The maintenance cost of solar panels is generally low. Routine maintenance such as cleaning the panels and checking for any damage or debris is recommended, which can be done by the owner or a professional. Additionally, occasional inspections and repairs may be required, but these costs are minimal compared to the long-term benefits of using solar energy.
