The Usage of Solar Polycrystalline Series (40W-50W)
- Q: I live in Sacramento, CA, and I need some solar panels for a project fo school. They don't have to be very big......just something that I can use as an example.Thanks!
- I did the same thing recently, if you'd really like some free ones then you need to look for those little solar powered lamps that people put in their yards, theyre about 0 inches tall and people sometimes line the paths through their yard with them. Maybe you can find a neighbor who doesn't want theirs anymore, or you could check local dumps for them. They each have a solar panel in the top, and they can be linked together to make more power. Alternatively, you can look on OKorder for a pack of broken solar cells, which still work fine but don't put out quite as much power as they did when they were new. However, they are very cheap. Hope this helps.
- Q: I want to build a solar panel

- Q: How do solar panels affect the overall comfort of a building?
- Solar panels can positively impact the overall comfort of a building by reducing energy costs, improving indoor air quality, and providing a more reliable and sustainable source of electricity.
- Q: Can solar panels be installed in a community or neighborhood?
- Yes, solar panels can be installed in a community or neighborhood. In fact, many communities and neighborhoods have embraced solar energy and installed solar panels on residential and commercial buildings. Installing solar panels in a community or neighborhood can contribute to a cleaner environment, reduce energy costs, and promote sustainable living. Additionally, community solar initiatives allow multiple households to collectively benefit from shared solar installations, making it accessible to a wider range of residents.
- Q: I am designing a solar panel but i need to have maximum power output.How can i optimize the equation for power Total power=voltage * current to get maximum power.
- first place the panel so it is at right angles to the solar rays. Make sure none of the panel has any shade whatsoever. For best results use motor drives to keep it in that position as the sun moves across the sky. For overall maximum versus time, you need to be near the equator. Solar cells have a high internal resistance, so for maximum power transfer, you need a load of that same resistance. A good charge controller will use DC-DC converters to provide that load. .
- Q: Are solar panels weatherproof?
- Yes, solar panels are weatherproof and designed to withstand various weather conditions including rain, snow, wind, and extreme temperatures. They are built with durable materials and are tested to ensure their resilience against outdoor elements.
- Q: How do solar panels affect roof maintenance?
- Solar panels can actually help extend the lifespan of a roof by providing an additional layer of protection from the elements. They act as a shield, preventing direct exposure of the roof to rain, snow, and hail. However, regular maintenance is still necessary to ensure the panels are clean and functioning optimally, as any debris buildup or damage to the panels could indirectly affect the roof.
- Q: Around this time here in Georgia we will begin to get some big storms with high winds. I have a solar panel on a mount that isn't all that sturdy and could be knocked over with any winds pretty much above 5mph. I can't put anything in the ground to do this. I used to have it mounted to the roof of a playground for the most sunlight, but because of the angle of the sun and the tree leaves, I have to have it on a quot;portablemount so I can move it throughout the day, and I can tell you one thing is certain, and that's that it isn't the most sturdy thing ever. I'll have it a little better next weekend but it'll still be able to easily blow in the wind. Should I just hang the panel along the wall during a storm then reconnect it to its base once it's over?I'm pretty good with wood, so any wood creations to help out with the thing would greatly help. Just please keep it on a low budget.
- You have to make the decision weather you want it portable or stationary. If you want stationary I would make some good brackets for them / search for cheap ones on OKorder. I'd have to see them to be able to offer any better suggestions. It's always hard to decide so you'll have to take notes and do research.
- Q: I am going to be building green in the next couple of years and i need an idea of how many solar panels i need in addition to a wind turbine to sufficiently handle a workshop, house, green house, etc. and what the approximate cost will be.
- With out the kW information of the need for your workshop no one can really tell you what you need for power supply. I would recommend you orientate your building or shop to maximize the passive solar potential. this will drastically eliminate your excessive need for heating and cooling. Which in turn will maximize your solar energy from the panels. Also depending upon what state you live in do some further research into any programs or grants offered by the power companies or state incentives. Regarding hydrogen...for get about it.
- Q: Can solar panels be installed on a community center or social gathering place?
- Yes, solar panels can certainly be installed on a community center or social gathering place. In fact, these locations are ideal for solar panel installation as they often have large roof spaces that can accommodate a significant number of panels. Solar energy can help power the community center, reducing electricity costs and environmental impact, while also setting a positive example for the community in terms of sustainability and renewable energy.
