Q:I want to put a solar panel(s) on my roof. What components do I need besides the solar panels? solar power controller? wires? How do I hook it into my home's electrical system and about how much electricity could I generate and save? Would the panels pay for themselves over time? Any help will be appreciated. Thank you!: The first thing that you have to realize is that solar panels only make DC currant. This is used to charge batteries which when hooked to an inverter will make 20 v. AC. You need a large bank of batteries and a heavy duty inverter to power your house. There is also an automatic switch that will send power back to the utility company when you have excess power available. This is not a small project. Really think this out before you invest a lot of money for nothing.

Q:I have a 2 volt deep cylce Everstart battery with 845 cranking amps, and a Grape Solar GS-S-250-Fab5 250-Watt Monocrystalline Solar Panel . I use them to power a 48Flat screen TV, a Roku, my 65 watt consuming MacBook Pro, and a 65 watt Fan.I know from previous experience that just the battery, an inverter, and the fan, that the fan will blow for 0 hours straight.Should I really be concerned with a Charge Controller?: Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.

Q:Actually I want to convert my home electricity on Solar Panel to cut down electricity costI have 2 AC's, a refrigerator, 3 Television, 2 Computers, 4 Fans etc: good okorder lots of good ideas there

Q:Can solar panels be used in combination with other renewable energy sources?: Yes, solar panels can indeed be used in combination with other renewable energy sources. Many renewable energy systems today incorporate a mix of solar panels, wind turbines, hydropower, and geothermal energy to maximize efficiency and ensure a reliable and sustainable power supply. This combination of different renewable sources allows for a more balanced and consistent energy generation, reducing reliance on a single source and increasing overall system resilience.

Q:What are the maintenance requirements for solar panels?: The maintenance requirements for solar panels include occasional cleaning to remove dirt and debris, checking for any damage or loose connections, and ensuring that the panels are receiving sufficient sunlight. Additionally, regular monitoring of the system's performance and scheduling professional inspections can help identify and address any potential issues.

Q:Can solar panels be installed in a desert environment?: Yes, solar panels can be installed in a desert environment. In fact, deserts are often ideal for solar panel installations due to their high levels of sunlight and minimal cloud cover. The dry climate also helps to minimize dust buildup on the panels, making maintenance easier.

Q:Do solar panels require regular inspections?: Yes, solar panels do require regular inspections to ensure optimal performance and identify any potential issues such as damage, debris, or faulty connections. Regular inspections can help in maintaining the efficiency and longevity of the solar panels.

Q:Can solar panels be used in remote areas with no access to the grid?: Yes, solar panels can be used in remote areas with no access to the grid. Since solar panels generate electricity from sunlight, they can provide a reliable and sustainable source of power in off-grid locations. By harnessing the energy of the sun, solar panels can charge batteries or directly power electrical devices, making them an ideal solution for remote areas without access to the traditional power grid.

Q:i am wanting to build a small tiny house running 3-4 2 volt 5 watt light bulbs for a lighting source and using a Koolatron Fun Kool 26 Quart 2V Portable Mini Fridge This cooler consumes 4.5 amps at 2 volts. The conversion is: 4.5 amps (X) times 2 volts (=) equals 54 watts. and i want a solar system that will have back up for 2 days with the lights on for probly 5-6 hours a day so theirs no room for error: you silly ! with Solar there is always room for error . you have to build it in to your numbers . solar is full of errors . So you should plan on producing at 3 times what you expect you will need . then you have enough .

Q:Can solar panels be used in areas with high levels of snow or ice?: Yes, solar panels can be used in areas with high levels of snow or ice. However, the efficiency of solar panels may be reduced during winter months due to reduced sunlight exposure. It is important to design solar panel systems in snowy regions with proper tilt and orientation, as well as implement measures like snow removal to ensure optimal performance.
