- Q: Can solar panels be used for powering electric lawnmowers or gardening tools?
- Yes, solar panels can be used to power electric lawnmowers or gardening tools. By connecting the solar panels to a battery storage system, the energy collected from the sun can be stored and used to power these tools, providing a sustainable and environmentally friendly alternative to traditional power sources.
- Q: this solar panel i saw was for 500 dollars(i get a 25% discount)and i was curious will they produce electricity? or just heat?what do they do?is it a good investment?here is a link to the one i would like, no reviews but it looks new to the site.
- This is a photovoltaic panel...it produces electricity from incident solar radiation. Solar thermal panels produce heat, and they are usually assists for hot water heating systems. Solar thermal panels have piping in them instead of semiconductor cells like photovoltaics do.
- Q: I am completely ignorant on this subject. I was just wondering out of curiosity of how many solar panels and equipment that it would take to run a central ac for a 2500 sq ft home and a pump for a medium sized pool. I'm talking running ac for like 8 hours a day to keep around 65-70 degrees and running the pump 24/7. Just looking for a general ballpark answer.
- Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.
- Q: how fast does a 25watt solar panel generate power to a battery? trying to figure out a conversion factor here to get a rough estimate of how many i would need to power my house, please help?
- To figure our how many you need, take a look at your power bill. It will tell you how many kilowatt/hours you used during the month. My bill says I use about 2000 kilowatt/hours per month, or about 2000 kwh /30 days=67 kw/h hours per day. That is 67,000 watt hours. To supply that with solar panels, you have to generate at least 67,000 watt hours, but you don't have a full day to do it, since you have to do it while the sun is up. So you put the energy into batteries during the day, so you can use it at night. A 25 watt panel generates about 25 watts when fully illuminated by the sun. If you fully illuminate it for an hour, you get 25 watt hours. If you get 2 hours of sunlight a day, that would seem to imply that I need 67000 watt hours/25 watts /2 hours=45 panels. But for most of the day, the sun isn't hitting the panel fully, so it isn't going to generate the full 25 watts. When the sun is 45 degrees to the side, you only get about 70%. When the sun is 60 deg to the side, you only get 50%. And what do you do on cloudy days? And the shorter days in the winter? To make up for this, you have to increase the number of panels to make up for the loss. So in reality, I might need double this number of panels, for realiable solar power throughout the year. That works out to about 90 panels, or ,250 watts worth for my house.
- Q: Am using 800watts sukam inverter and have 55watts panel. What controller can i use to connect my solar system to have a max power . Already i have 200 Amp/hr battery
- If that 55-watt panel has an open circuit voltage of 7-8 volts, you may get more efficiency by omitting the charge controller completely, and connecting the panel straight to the battery. 55 watts is marginally too small for a 200 AH battery at 2 volts, by the way.
- Q: please no dumb answers and list where you got the info.Also how much does it cost to install solar panels for a regular sized house?
- Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .
- Q: first of all, to be honest i have totally no idea on how a solar panel works.my task is to design something like a solar powered street lamp which store sun energy during day time and convert it into electrical energy then light energy so that the lamp can work during night time.any ideas on how to design the solar panel? which can store enough or more enegry in case there is no sunlight another day. and low cost as well :D
- solar panels change light into electricity, and do NOT store power. You need a solar panel capable of enough power to keep the light on all night. And that may be 6 hours of sun and 2 hours of dark. Then you need a set of batteries large enough to hold that energy. And a charge controller to regulate the charge into the batteries. And then a light that will operate on the battery voltage, say 2 volts. This is probably not practical due to the large solar panel required, and the large batteries. But here is a few numbers. Assume a 00 watt light at 2 volts. Assume you get at least 6 hours of sun every day and the light will be on for 2 hours. That means the battery has to store 00*2=200 watt hours. divide by 2 and that is 00 amp-hours, a large auto battery size. Allowing for 20% losses in the battery and circuitry, that means you nee 400 watt hours from the solar panel. Since it has 4 hours to operate, that means it has to deliver 400/4 = 350 watts at 5 volts. So there it is: 350 watt panel 00 amp hour battery charge controller sized for above 00 watt light. If you have to allow for a day with no sun, then you need more batteries. Two nights means 2400 watt-hours, two batteries, a larger charge controller and a 2800/4 = 700 watt panel. cost: $400 for batteries $200 for charge controller $2000 for panel .
- Q: Hello everybody, the area we are living has energy crises with no electricity available most of the time. What I am thinking is to buy a solar panel with other required accessories. Please note we have normally long sunny days most of the time during a year.Please advice installing solar energy system would supply energy 24/7? I have a television, a dvd player, a fan, 4 energy saver lights (2 watt each) and a laptop. Please also advice the specifications for the system to be installed and the points I need to ensure at the time of purchase. I think of buying a solid battery (not acidic battery)The forum is open for your kind suggestions.Thanks!
- We put in photograph voltaic panels before this year, for the final six months we've became on our oil fired boiler approximately seven circumstances, for an hour every time. we are living in north Scotland. Our panels are for water heating only, they comprise fluid which passes by our warm water storage subsequently elevating the temperature. For a 4.4m panel and a greater complicated than regular setup it cost us ?3500 alongside with labour. even nevertheless i've got faith you're thinking approximately panels for producing electricity? wherein case that form of photograph voltaic panel is woefully innefficient in this u . s . a .. i could advise to everybody to in effective condition photograph voltaic panels for water heating, it has stored us a fortune so a procedures and might pay itself back in approximately 5 -0 years depending on oil expenses. For electricity era nevertheless? no longer cautioned. As for grants, as quickly as we utilized we've been informed that all the supply money were used up and that became into that.
- Q: Do solar panels require a backup battery system?
- No, solar panels do not necessarily require a backup battery system. However, having a battery system can be beneficial as it allows for the storage of excess energy produced by the solar panels, which can be used during times when there is no sunlight or during power outages.
- Q: How much would it cost to make an average size house be able to depend on solar panels for all of its power?How many solar panels would you need and wear would you put them? Would the roof be large enough to support the panels needed?Do solar panels work well in higher latitudes like northern USA or southern Canada? Can you power your house for the whole year if you live in these environments? What kind of maintenance do solar panels require?
- There are several web sites you can search for and they will provide the answer on how big of a PV Solar Array you would need for your house. Several things need to be known, such as square footage of the home, how well the home is insulated, etc. The panels come in all sizes and wattage's depending upon application, so yes they should all fit on the roof. If you have a small roof get PV panels with higher wattage's. Yes, they will work in the northern latitudes but not as efficiently as near the equator. You might need more PV panels to make up the loss in power from the sun hitting at a lower angle. Generally, all you will need to do is periodically clean the glass covering of the PV Panels to get maximum sun light on the PV cells. In my region, near the 45 th parallel, a 600 square foot home with six inch insulated walls and R40 attic insulation can purchase a PV panel system for around $40,000. That includes the equipment to tie it into the power grid and the meter to measure how much you supply the grid during the day and how much you draw from the grid at night when the sun isn't shining. There are tax credits for retrofitting an existing home, but mostly it is new homes being built that are having the PV panel systems installed so the cost is added to the mortgage and the return on the investment is paid off over the life of the System (about 5 to 20 yrs.)
