- Q: Can solar panels be installed on sloped roofs?
- Yes, solar panels can be installed on sloped roofs. In fact, sloped roofs are one of the most common types of roofs where solar panels are installed. The angle of the roof can be adjusted to optimize the positioning of the solar panels and increase their efficiency.
- Q: Making a solar panelI know there was a recommended wattage for the soldering iron but i cant rememberdoes anyone know?

- Q: Can solar panels be installed on a barn or agricultural building?
- Yes, solar panels can be installed on a barn or agricultural building. In fact, these structures often provide ideal conditions for solar panel installation due to their large, unobstructed roofs and proximity to open spaces that receive ample sunlight. Installing solar panels on barns or agricultural buildings can help farmers and landowners generate renewable energy, reduce electricity costs, and contribute to a more sustainable future.
- Q: Are there any limitations to the lifespan of solar panels?
- Yes, there are limitations to the lifespan of solar panels. Over time, solar panels experience a gradual decrease in efficiency due to factors like exposure to environmental elements, wear and tear, and potential manufacturing defects. Additionally, the materials used in solar panels may degrade over time, which can affect their performance and overall lifespan. However, with proper maintenance and regular inspections, solar panels can typically last for 25 to 30 years or even longer.
- Q: Are there any free classes to learn about solar energy and building a solar panel

- Q: A few months ago my dad said something about getting solar panels, and how green they were. I was just wondering if there were any companies that sold them and if they would actually make a big difference.
- It okorder They will rent you a solar panel system. You will pay a flat monthly rental rate that would be locked in for up to 25 years. There's no installation cost, No system to purchase, No permit hassles, No Maintenance fees and a locked in rate for up to 25 years. Check it out. I think you would like it. You won't own the system but you will save money and help our environment in a huge way. Also by renting a system you save yourself from future advances in solar. Example Things are changing fast in the solar industry. If you go out and buy a system for $40000 today and next week comes around and you can get a cheaper, more effecient system you would still have to pay for the one sitting on your roof.
- Q: Can solar panels be used in areas with high wind speeds?
- Yes, solar panels can be used in areas with high wind speeds. However, it is important to ensure that the solar panel installation is designed and constructed to withstand strong winds. This can be achieved through proper mounting and anchoring techniques, as well as using wind-resistant materials. Additionally, tilt angles and panel positioning can be optimized to reduce the effects of wind resistance.
- Q: Are solar panels fire hazards?
- Solar panels are generally safe and do not pose a significant fire hazard. However, like any electrical system, there is a small risk of fire if there are installation errors, damaged wiring, or improper maintenance. Proper installation and regular inspection can minimize these risks and ensure the safe use of solar panels.
- Q: I have in mind a small solar panel that could be plugged into a wall socket. Do I need a converter or some kind of interference between the two power sources so there aren't any unpleasant explosions? I don't know much about this sort of thing so please be nice.
- The other responders have given partial information. The electricity in your house is 20 volts AC and the solar panel will produce DC voltage. If you plugged in the solar panel into the wall, the solar panel would be destroyed, possibly with disastrous results. If you connected the solar panel to a DC to AC inverter, there are also dangers. The solar panel unless very large will not produce enough power to make a lot of AC, for every amp of 20 volt AC, you require more than 0 Amps of DC voltage. So most small solar panels are used to trickle charge a 2 volt battery used in backup situation. The problem is that the house AC and the inverter AC have to be exactly in phase or again you have disastrous results. If they are exactly 80 degrees out of phase, the wires now are carrying 240 volts and you will burn out the inverter, and possibly cause a fire. There are systems that will synchronize an inverter to commercial power so that you can feed the power back to the grid, but these are more complicated. If you want to use the battery and solar panel to run some lights during power failures, then you can connect the light to the common terminals of a switch, but the switch must be a break before make switch, which means that when you throw the switch the common is disconnected from the one source before it is connected to another source. Most AC switches will do this, but make sure.
- Q: I'm looking into buying solar panels, there are all kinds of ranges of energy output...but my question is, when ti says...say 50 watts of power...does that mean 50 watts a day, an hour, a minute, what?
- A 50-watt rating means the panel will produce 50 watts as long as the standard conditions are maintained. So if you had this bright sun and cool temperatures for 6 hours, the panel would deliver 50 x 6 = 900 watt hours, or a little shy of kilowatt-hour. Kilowatt-hours (kWh) is the reading on your electric bill. However, like most advertising, the 50-watt number is not realistic. They assume that the air surrounding the panel is very cold. 25 watts is a better number to use for this size of panel for engineering purposes.
