WORK PRINCIPLE
MAINTENANCE
The modules are designed for long life require very little maintenance. If the angle of the PV module is 5degrees or more, normal rainfall is sufficient to keep the module glass surface clean under most weather conditions. If dirt build-up become excessive, clean the glass surface only with a soft cloth using water. If cleaning the back of the module is required, take utmost care not to damage the back side materials. In order to ensure the operation of the system, please check the connection of wiring and the state of the jacket of wires every now and then.

- 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:How do solar panels impact air pollution?
- Solar panels have a positive impact on air pollution as they produce clean energy without emitting harmful pollutants or greenhouse gases into the atmosphere. By replacing fossil fuel-based energy sources, solar panels help reduce air pollution and improve air quality, resulting in a healthier and more sustainable environment.
- Q:Thinking about getting a solar panel installed but i'm worried about getting the govt. rebates. There is a Federal Tax credit and a State of Florida rebate and i'm wondering what the time frame is for getting the rebates. Has anyone gotten a solar panel installed recently that could give me more info.Thanks!
- In case you hadn't heard the state is broke.
- Q:I am thinking of buying a 3w solar panel called the nomad 3 from goal zero. I want to charge 35Wh lithum batteries. I have heard that lithium batteries are temperatmental and without a regulated current things could get ugly.I have a couple of chargers that came with the batteries. One is a 2v car charger and another is 0-240v wall charger.Goal zero sell something called a sherpa 50, which contains rechargeable batteries and an inverster and I think they suggest that I charge my batteries indirectly through the Sherpa 50, however, the sherpa 50 is expensive at $200, and seems to have a small capacity, in addition to being extra weight that i don`t want to carry.Electronics geniuses, you are my only hope.
- If you want to energy each USB ports on the identical times, It could not be possibble. Your sun panel best provides 2.24 Watts (20V * 0.2A) of energy and you ought to deliver 2.5 Watts (5V * 0.5A) to the ports. Subtracting any losses out of your regulator(s), you are going to be method over your vigor finances. You'll want extra of a sun panel or less of a load.
- Q:Can solar panels be used in areas with high levels of air turbulence or strong winds?
- Yes, solar panels can be used in areas with high levels of air turbulence or strong winds. However, it is important to ensure that the solar panel installation is designed and built to withstand these conditions. Proper mounting systems and structural support can be implemented to secure the panels and minimize any potential damage caused by strong winds. Additionally, choosing robust and durable panels can further enhance their ability to withstand turbulent air or high wind speeds.
- Q:I hooked up a 2V solar panel to a small relay. The relay switches at 9V. When I have light shining on the panel it puts out aorund 3-4V, but when I hook it up directly to the relay it drops to V and doesn't switch the relay. Why? and How do I fix it?-2V Mono-Crystalline Solar Panel -JWD 7 4 reed relay
- Do you know what is the rated Peak watts of the solar cell and the current needed to operate the relay. The power needed to operate the relay can be found from 9V * operating current, and that should be lower than the peak output power of the cell (perhaps significantly less as the peak power is produced only at high solar radiation levels. Another factor is whether the curves for the solar cell match the load. Typically the solar cells have a knee type diagram for the VI relationship, and that is why they need Maximum Power Point trackers to deliver a good power output.
- Q:How can solar panels be used for heating water?
- Solar panels can be used for heating water by utilizing the sun's energy to generate electricity, which powers a heating element that warms the water. This process involves the conversion of solar energy into electrical energy, which is then used to heat the water, making it an eco-friendly and cost-effective method for water heating.
- Q:Can solar panels withstand extreme weather conditions?
- Yes, solar panels are designed to withstand extreme weather conditions such as high winds, heavy snowfall, and hailstorms. They are made with durable materials and undergo rigorous testing to ensure their resilience.
- Q:I got a really great deal on 2 houses because they were fixer-uppers. I'm living in one and the other I'm renting out. However, the previous owner did everything himself in 950 95, so needless to say, things are not to todays standards. Both houses need rewiring (there are no ceiling lights, few outlets, and mine has two old fuse boxes and the other has a breaker box but it pops the breaker a lot). The only reason they are still functional is because both houses use natural gas for water and heat, so otherwise, they electrical work is getting us by, but who knows for how long. I thought that maybe instead of redoing the electric, that I could just add solar panels to compensate for the small electric boxes. Also, since I would have to hire electricians to do all the work, which would be more cost effective (not including the decrease in utilities since I don't pay the utilities in the rental anyways)?
- A solar panel does not replace the wiring in your house. All it does is supply power to the house, the same way a line in from the street does. After the power gets to the house, regardless of how it got to your house, it goes through exactly the same wiring to get to outlets and lights. Your problem is not that the power coming in from the street is insufficient; the power company can supply all you'd ever need. The problem is that your houses are not wired to receive or use more power. You need to upgrade the service panel so it can bring more power into the house, and upgrade the wiring inside the walls so you have the number of outlets and lights required by today's codes and which most of us need for all the things we plug in these days. Solar panels, while they are cheaper than ever, are not a low cost thing to install. It will take years to recover their cost, and if the rules are the same where you are as they are here, you can't use the cost of installing them as a write-off against the cost of the house until you sell it. They are a capital expense, not a maintenance and repair deduction which you can use each year against the income you receive from the rental. Doing a conventional rewiring is your best bet.
- Q:Can solar panels be leased or financed?
- Yes, solar panels can be leased or financed. Many solar companies offer leasing options where the panels are installed on your property and you pay a monthly fee for their use. Alternatively, solar panels can also be financed through loans or financing programs, allowing you to purchase and own them over time while making affordable monthly payments.
