- Q: I know that if I put solar panels in my home I will get 30% back from the govt. Does that mean if I pay 2K I will get back around a 3K check? Or will my income play a roll where I may not get back as much?
- It's not your income, but the tax you pay. This is a NON refundable credit. You won't see a difference unless you actually owe tax. If you are retired and living on social security and savings, you don't pay tax, so you'd get $0 from the solar panels. If you are married, have a bunch of kids and get a refund of all money withheld anyway, you'd get $0 from the solar panels. If you currently average, say $200 in actual income tax, your $2,000 investment would create a $3600 tax credit, but you'd only get back $200 the first year. (This would reduce the tax bill, increasing any refund of money already withheld to pay that tax bill.) The remaining amount would carry forward to 202. You can keep carrying it forward as long as the credit is available (I think that's currently 206). Get your 200 return out and get form 5695 and run the numbers. Edit, ignore TRO. She doesn't keep up with tax law changes. BOTH the residential and solar credits exist in 20. The Residential credit now limited to $500.
- Q: I need to be able to charge a 2v 7amp battery with a solar panel. I understand that the charge controller will keep the battery from over charging/discharging, but what I don't understand is the amps.The solar panel is rated at 5watts.The solar panel comes with a 2v 3amp charge controller but will I need to buy a 7amp charge controller and replace it with that for my battery pack? Please explain. Thanks in advance.
- If it is a charge controller that is wired between the panel and the battery only, then a 3A rating is ample. The controller only has to handle the maximum current that the solar panel can output. The panel will have (or needs to have) an open-circuit voltage that is greater than about 4V in order to actually charge the battery, whose terminal voltage will rise above 2V as it charges. The panel's open circuit output voltage typically is about 7V. The 5W rating is at the maximum power point under the illumination of standard sun and at a specified temperature. That maximum power point probably is around 4V, which means the panel will deliver the following amperage to charge the battery: I = P/V = 5W/4V = 0.36A Since 0.36A is well below the 3A rating of the controller, the controller will not be overloaded when charging the battery. Some charge controllers also have terminals for connecting the load that you want to power. If that's the case, then the controller also needs to be rated to handle that load amperage or higher. If you were to connect a 6A load, then you would like to have say a 0A controller. Hope that helps.
- Q: What is the impact of roof color on solar panels' performance?
- The impact of roof color on solar panels' performance is minimal. While a darker roof color may slightly increase the temperature of the panels, leading to a slight decrease in efficiency, the difference is typically not significant enough to significantly impact their overall performance. Other factors such as panel tilt, orientation, shading, and maintenance have a much larger influence on solar panels' performance.
- Q: Can solar panels be installed on a shipping container?
- Yes, solar panels can be installed on a shipping container. In fact, many people and businesses are now utilizing shipping containers as a platform for solar installations due to their portability and ease of installation.
- Q: What is the impact of roof age on solar panels' efficiency?
- The age of a roof can have a significant impact on the efficiency of solar panels. An older roof may have deteriorated shingles or structural issues that can affect the installation and performance of solar panels. Additionally, an older roof may require repair or replacement in the near future, which would require removing and reinstalling the solar panels, incurring additional costs and potential damage. Therefore, it is important to ensure that the roof is in good condition before installing solar panels to maximize their efficiency and longevity.
- Q: I thought that I had a fairly good understanding of watt's law, but i'm starting to doubt myself.If I have a load of 4500watts at 240 volts, how many watts of solar panels do I need, if the solar panels are at 2v?Yes, Yes... I have a charge controller, batteries, etc...So the way I looked at this at first:watts = volts * amps For the load4500 = 240 * xx would be 8.75aFor the power source (each solar panel)00 = 2 * xx would be 8.3a8.75 / 8.3 = 2.25, rounded up = 3So... based on that I came to the conclusion that I needed 3 solar panels...But... then I was thinking. Does it work that way?Or do I need 4500 / 00 = 45, aka 45 solar panels?In other words...If I have a 2v power source, how many watts do I need to drive a load of 4500w at 240v?ThanksMatt
- The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.
- Q: A homeowner is considering putting a horizontal solar panel on her roof to heat water for domestic use. An average increase of water temperature each day from 60oF to 20oF is wanted for 50 gallons. How large a panel would be needed on a clear winter day at 40o latitude if the overall efficiency is 50%?

- Q: Looking to install solar panels in my house.
- Wholesale prices for BP solar panels range between $335 for the 40 watts panel to $835 for the 70 watts panel. Here's a brief listing of wholesale prices for BP solar models: - BP340J solar panel (40 watts) @ $335 - BP350J solar panel (50 watts) @ $37 - BP375J solar panel (80 watts) @ $504 Right now I'm getting a series of 50 watt (7.5 volts) panels installed in my house. It's a start to reduce dependence on electricity bills and try get some tax rebates as well.
- Q: Can solar panels be used in areas with high levels of shade or obstruction?
- Solar panels can still be used in areas with high levels of shade or obstruction, but their efficiency and power generation may be significantly reduced. Shadows or obstructions can cause partial or complete shading on the panels, which can lead to a decrease in energy production. However, advancements in technology, such as the use of microinverters or power optimizers, can help mitigate the impact of shading by allowing each panel to work independently and optimize energy production. Additionally, proper placement and angle adjustments of the panels can also help maximize sunlight absorption, even in shaded areas.
- Q: Can anyone give me a simple but informative explanation on how solar panels produce electricity/power? Thank you!
- This forum of solar panel is for electric You also get a diffrent type of solar panel this type of panel has a liquid that flows through it and is heated up by the same photovoltaic cells but is ran through the water tank to keep the water warm
