Q:The battery is 9ah and the solar panel is 20w

Yes, certainly. So long as the solar panel's voltage exceeds the voltage of the battery (which is probably going, certainly if it can be a discharged battery, which is lower than 2 volts), then it will recharge the battery. Additionally, a 2 V solar panel can produce bigger than 2 volts. Nevertheless, the rate of charging is more likely to be depdendent on the availabilty of daylight. And of course, the better the capcity of the battery, the longer it takes to cost.

Q:Can solar panels be installed on fences?

Yes, solar panels can be installed on fences. In fact, installing solar panels on fences is becoming increasingly popular as it maximizes space utilization and allows for efficient energy generation in areas with limited roof space. Additionally, fence-mounted solar panels can provide added privacy and security benefits.

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:Can solar panels be installed on a streetlight?

Yes, solar panels can be installed on a streetlight. This is known as solar street lighting, where solar panels are mounted on top of streetlights to generate electricity from sunlight and power the lights.

Q:Basically I need a custom solar panel created. I won't go into detail but the dimensions need to be around 4''x2.5'' and be as thin as possible.

There's no way that home built system that will generate enough power to run your home off the grid. That's all hogwash! No wind = no electricity generated. No sun = no electricity generated. I'm looking into a grid tie solar system. I'm still working out the math for my home. They are expensive ($20k - $50k) before tax credits, but they have been designed by engineers, not back yard, shade tree wanna-be engineers. They will put power into the grid during the day (making your meter run backwards) and you'll draw the power back at night (when there's no sun). This is perfectly legal. It must be installed by power company approved techs. That's how power companies are going to meet their green energy mandates for the future. You'll generate power for the power company and get paid wholesale prices for it (during the day). But you'll buy it back at retail (at night)

Q:I don't have a regulator connected as they are a little expensive for a pensioner, If I join the panels into line to the battery bank from the roof should that be OK.?

Two things on a regulator: a) It will optimize the charge to the batteries - and thereby distribute the most possible power to your active circuits during the day. b) It will prevent the power from the panels from boiling (no kidding) the batteries - no small thing as they are the second largest investment you have after the panels themselves. This is much more critical if you have sealed or Zero-Maintenance batteries. I strongly suggest that you get a regulator as it will significantly lengthen battery life. Follow the directions on the regulator for optimum input voltage and it will let you know whether all the panels should be in series, parallel or series/parallel. But cutting to the chase, you can certainly gang up panels as needed.

Q:Can solar panels be installed on schools or educational campuses?

Yes, solar panels can be installed on schools or educational campuses. In fact, many educational institutions are increasingly adopting solar energy systems as a sustainable and cost-effective solution for their power needs. Installing solar panels on schools not only helps reduce carbon emissions and reliance on fossil fuels, but also provides educational opportunities for students to learn about renewable energy and its benefits. It can also lower electricity bills and redirect saved funds towards educational programs.

Q:What are the advantages of using solar panels?

There are several advantages of using solar panels. Firstly, solar panels produce clean and renewable energy, which helps reduce greenhouse gas emissions and combat climate change. Secondly, solar energy is abundant and free, reducing the dependence on fossil fuels and providing a sustainable source of power. Additionally, solar panels can save homeowners and businesses money on their electricity bills by generating their own energy. Finally, solar panels require minimal maintenance and have a long lifespan, making them a cost-effective and reliable energy solution.

Q:Can solar panels be used in off-grid systems?

Yes, solar panels can be used in off-grid systems. Off-grid systems are designed to operate independently from the electrical grid, and solar panels can generate electricity from sunlight, making them a reliable and sustainable source of power for off-grid applications.

Q:Parents planning on buying some solar panels for our house down in Dubai it really hot there I'm currently living in Canada, anyways I'm wondering how many solar panels and volts ill need to light up a 2400sq ft. House? Please leave you're suggestions below!

It's not really the solar panels that power the house, they charge a battery bank and there's an inverter that jumps the battery power up to household current level. If you start getting into more expensive systems, they can sense when the batteries are full and start diverting power into the local electric grid. Some places the electric company is required to pay you for generating current, other places tell you tough luck. I suggest looking on OKorder or something at some of the home solar kits on sale there and look at how large a house they are rated for to get an idea of how big a system you're going to need. I don't know if you have access to the power bill history of the house you're getting in Dubai, but the power company there might be able to provide you with a history of average kW hours the house consumes. A 2400 sqft house with a gas stove and a gas water heater and wood heat is going to consume far less electricity than a house with all electric appliances and the consumption history of an individual house should reflect that so you can buy appropriately.
