- Q:I heard that solar energy has a lot of advantages but are there any drawbacks in using the solar panels?
- The major drawbacks are the high cost with low power payback. Also, the sun isn't shining for a good share of the time. life span is 20-30 years and then you have to spend the money all over again. It's cheaper to use public utilities for power, but not as green.
- Q:If i took a lazier pointer and aimed it a solar panel would it take in the light. Also what types of lights would work on a solar panel like L.E.D, uv light bulbs.
- a million. Do they scratch actually? No How do I eliminate snow from them without scratching them? purely wipe the snow off 2. What does the maintenance of many image voltaic panels contain? sparkling them with faucet water and paper towels as quickly as a month. 3. Are all image voltaic panels created from the comparable fabric, regardless of length? extremely the comparable.
- Q:How do you make solar panels and do you need a lot of them to make electricity?
- Have okorder . It could obviously explain everybody!
- Q:What are solar panels?
- Solar panel is a generic term used to describe a device that collects and converts solar energy into electricity or heat. Photovoltaic module, used to generate electricity Solar thermal collector, used to generate heat Solar hot water panel, used to heat water, often in homes but i guess u mean the ones which generete electricity a photovoltaic module is a packaged interconnected assembly of photovoltaic cells, also known as solar cells. An installation of photovoltaic modules or panels is known as a photovoltaic array. Photovoltaic cells typically require protection from the environment. For cost and practicality reasons a number of cells are connected electrically and packaged in a photovoltaic module, while a collection of these modules that are mechanically fastened together, wired, and designed to be a field-installable unit are known as a photovoltaic panel or simply solar panel. A photovoltaic installation typically includes an array of photovoltaic modules or panels, an inverter, batteries (for off grid) and interconnected wiring.
- Q:Home depot has solar panels but they are so expensive? were is the best place to get them?
- You okorder (or any other website you can find in a search engine) to get a list in your area. Good luck!
- Q:wondering if i should get them?? not sure if its worth leasing? also anyone know anything about solar city?
- It okorder He has a modest system, and soon will be uploading some useful informaiton on cosntructing smaller solar arrays from individual small cells salvaged from various items. At some point too he will cover converting some items people would not really think of to running on 2 volts that once were 20 VAC items. I know the author.. so I get previews. If you post a question in his comments on some aspect or detail or if something is not real clear, he will try to address them too.
- 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:but is that per day, per hour or minute?How much watts does the average AC unit use?How much does an energy efficient lightbulb use?All in all let's hypothetically say we no longer use the electric company for our energy source, How many of these panels do you estimate it would take to supply our small home?
- It's virtually impossible to estimate how many panels would be required, without knowing your electrical usage, and where the house is located. I'll give our house as an example, but it could be off by a factor of 0 (not kidding) from yours. We have gas heat, no air conditioning, and no pool. We live in a dry, sunny area of California, and our roof is ideally oriented for panels. We would need 25 such panels, but we are grid-tied. If we wanted to disconnect completely from the electric company, we would need 20% more panels to compensate for battery inefficiencies. So, the estimate is 30 panels. Here are some caveats: ) Air conditioning, especially central air, could double or triple the estimate. 2) An area that gets less sun per year (northern US, for example) would need more panels. 3) Typically, when a house has grid electricity, they keep grid electricity when they get solar panels. It's much cheaper to use both in tandem. 4) That's a horrible price for the panel in the picture. You can find a 200-watt panel for less than that. 5) Other equipment is required besides the panels to run your house off solar. You can read up on it on the internet, or ask a professional solar installer for a free quote.
- Q:Can solar panels be installed on a remote island or location?
- Yes, solar panels can be installed on a remote island or location. Solar panels require sunlight to generate electricity, so as long as there is adequate sunlight in the area, they can be installed. Remote islands or locations often benefit from solar panel installations as they provide a clean and renewable source of energy without the need for extensive infrastructure or reliance on fossil fuels.
- Q:What is the average size of a solar panel?
- The average size of a solar panel is typically around 65 inches by 39 inches, or approximately 5.4 feet by 3.25 feet. However, the actual size can vary depending on the manufacturer and the specific model of the solar panel.
