- Q: Rooftop solar panel (not sure if rubber or plastic?) has leak arising from thin vertical crack in panel about long. Any ideas for repair?Thanks.
- bypass the whole panel if you can ( one individual panel of several ) , or bypass that loop in that panel - car part rubber hose clamps
- Q: Can solar panels be installed on residential complexes or apartment buildings?
- Yes, solar panels can be installed on residential complexes or apartment buildings. In fact, they are increasingly being installed on such structures to harness clean and renewable energy for multiple households. The installation process typically involves placing the panels on rooftops or in open spaces within the complex, allowing residents to benefit from reduced electricity costs and a more sustainable living environment.
- Q: I have a solar panel 7.5V .25W 50mah, connect 2 in parallel to power a RC boat. The boat use to run on 6cell battery pack - 7.2V 800Mah.The dc motor requirement based on the provided battery pack, i assume would be 7.2V and rated at (7.2V * .8Amp) = 2.96 Watt.Would two of my solar panels run this DC motor ?are my calculations or understanding correct ?do lend a hand dear ''world''
- solar cells are not rated in mah, they are rated in ma or amps. I'll assume this one is 50mA. Two in parallel will give you 300mA, so that will charge a 800mA-hr battery in 800/300 = 3 hours. Theoretically, in bright sunlight if the array is exactly at right angles to the sun's rays. The problem is, depending on the type of cells, the battery pack will need 8 volts or so to charge, and your solar cells won't deliver that. If the sun is at an angle, you may get only 3-5 volts. so you have to put them in series, so you will get only 50mA out of them, which will charge the battery in 6 hours of bright sunlight. Would two of my solar panels run this DC motor ? If the motor is .8 amps, you need the battery, the arrays are not near enough. Or are you attempting to replace the battery pack with the solar array? Your english makes that difficult to understand. If so, put them in parallel to get the 300mA, but that would run the .8 amp motor very slowly. If you had 2 of the solar panels, it might run at close to full speed if the sun is bright and shining directly on all the panels. But where did you get the .8 amps for the motor? The 800Mah rating of the battery has ZERO to do with the motor current. So the answer above is based on your number, which I suspect is totally wrong. .
- Q: Due to erratic power cuts in my area I want to make up by using a 30watt solar panel. My decoder is 30watt but my TV is 70W. I need something small. I don't have problem with sound. Just picture.
- Do what we do when power is cut (although we have very reliable power - we loose as much as 2 hours a year), is go Amish. That is go without powered technology. Now, for you, you need more than a solar panel (and likely more than 30W, but that is a start) - you need a battery or set of batteries to store the collected power. 20Ah might do. You need an inverter to power things. For that, likely a 300W will do. For a TV, go shopping, and look at the labels on the back of the TVs. I just bought a 24 TV rated at 40W. If you get a 9 LED TV, it may be likely you can run that directly from battery, for many have separate DC brick supplies. With those, you can make a cable to power it directly from a 2V or so battery, if the supply can make 2 to 5V. Depending on your provider, you may be able to get a mini-decoder which uses a separate brick or wall supply, which means the decoder likely can be directly battery powered. Such a decoder may draw less than 20W.
- Q: Can solar panels be installed on a warehouse or storage facility?
- Yes, solar panels can be installed on a warehouse or storage facility. In fact, warehouses and storage facilities are ideal locations for solar panel installations due to their large roof spaces and often minimal shading. Installing solar panels on these structures can help reduce energy costs, lower carbon footprint, and generate clean, renewable energy.
- Q: I live in a higher LATITUDE so in the winter months, there is a limitation in the amount of sunlight available, but will this impediment restrict the ability of solar panels to function due to the lack of sunlight involved?
- Solar panels generate power only during sunshine hours. But they only need sunshine, they don't like the heat, that comes along with the sunshine. So its a trade off, the places that have a lot of sun, also have a lot of heat, and places that do not have a lot of sun are not that hot. But you do need sunlight to run solar panels. There's a lot of tools available which can tell you how much power you are able to generate given your location.
- Q: Can solar panels work at night?
- No, solar panels cannot generate electricity at night as they rely on sunlight to produce power.
- Q: what percentage of sunlight is converted into electrical energy in a solar panel?
- Thin film panels are typically 5-7% efficient. Crystalline panels are typically 0-4% efficient. Both types of panels will degrade overtime, so the efficiencies above are only for new panels.
- Q: Can solar panels reduce electricity bills?
- Yes, solar panels can reduce electricity bills. By harnessing solar energy to generate electricity, homeowners can offset a portion or even all of their electricity consumption from the grid, leading to lower electricity bills.
- Q: I purchased some small 3.6 v 70mA solar panels online. I have no experience with solar panels. I am confident of the layout of the parallel circuit I want to create, however I don't know how to properly connect the tabs that come from the sides of the panels. Any help on connecting them?
- Each solar panel will be wired to each other in parallel if you have more then one. When you wire in parallel the amps(current) from each panel will add to the total sum of current, but the total voltage stays the same. The voltage must match the rest of your system. For example, if your are using 2 volt solar panels you must be using 2 volt batteries and voltage regulator. Voltage regulator must be rated above maximum voltage and current(amps). Connect the output from the solar panels to a properly rated regulator, solar panel voltage regulators are rated by maximum voltage and amps, that will shut off the current flow to the batteries once the batteries are sufficiently charged there by preventing damage to the batteries. The way that you figure the rating needed for the regulator is by adding the maximum amps for each solar panel, this should be listed on the solar panel, and if they are 2 volt panels and they are connected in parallel then max voltage should be around 22 volts. It's the amperes that is most importance when choosing a regulator
