- Q:Hi everyone, I am a novice in solar energy system. I want to know if I am on the right track. Recently I bought a 30 W solar panel, 5 Amp controller, and a 22 Ah battery, how many watts and what kind of INVERTER do I need? I did an research some said 50 W and some said 300 W. And am I right on the 5 amp controller and 22 Ah battery to provide larger output of electric, or the higher the # the greater output for 30 W solar panel?Really appreciate for anyone who help!!!
- With a 30 watt panel, producing about 2 amps, your not going to have much power from that. A 22 AH battery will give you 2 AH of usage. A battery should never be drained below 50%. What this works out to be is simply Amp draw for 2 hours. Which equals to 2V light bulb that draws amp for 2 hours. Not much. Now to replace that usage with your 30 watt panel, provided the panel is clean and in max sunlight, it will take 6 hours. If you attach an inverter to your system for 5 Volt Usage then the DC voltage drawn from the battery is very high. Example: Say you use a 5 Volt component that requires 50 Watts per hour to operate. The inverter will draw 5 Amps out of the Battery every hour to operate that component. That gives you and /2 of use before the battery is down to 50%.. Maybe that will be enough to charge up a standard Laptop battery. I have 2 30 Watt panels that produce 5 Amps, 4 6V batteries that have 480 AH and a 25 Amp Controller with a booster that increase the amp output to 20 Amps per hour. I live full time in an RV and raise the panels to get max output when I am parked. This system provides me with all the 5V throught the 500 Watt inverter that I need. Good luck on you system.
- Q:Interested in buying solar panels to save on electric bill.Any government help plans?
- Yes, okorder / Also, realize, that installing solar is generally not an instant-save proposition. You pay thousands or tens of thousands of dollars to get the system installed, then it pays you back over the years. You need to talk with a local installer to see if the financial case makes sense in your situation.
- Q:Can solar panels be installed on a warehouse or distribution center?
- Yes, solar panels can be installed on a warehouse or distribution center. In fact, these large, flat-roofed buildings are ideal for solar panel installations because they offer ample space and can generate a significant amount of renewable energy. Installing solar panels on warehouses or distribution centers can help reduce electricity costs, decrease carbon emissions, and contribute to a more sustainable energy system.
- Q:how the power output of solar panels fitted to a house can chargenothing on the internet really answers this question, any information will really help..this is for GCSE, i don't really understand the meaning of the question. does it ask how the solar panel egts charged, and how it works? i don't get how you can charge a solar panel and is heat the only way you can produce electricity for it??please answer if you know! much appreciated!!! thank you so so so so so so so much, in advance =)
- Solar panels do NOT get charged, so the question is junk, or you misstated it. Solar panels are used to charge a battery bank, which stores energy for times when there is no sun. Then energy from the batteries is used, via an inverter, to power appliances in the house. OR do you mean how the power output of solar panels can CHANGE? In that case, they change when the sun moves, such as behind a cloud, or just changes angle in the sky, or goes out.
- Q:Is it possible for a 2V rated panel to charge a bank of batteries equal to around 36V? I believe that the panels should equal or exceed the voltage of the batteries but, I'm not for certain.
- You're right. The solar panels must produce a voltage equal to or slightly greater than that of the batteries. So you need to either switch to a 2 volt battery or add two more solar panels of the same current rating.
- Q:Are solar panels affected by temperature?
- Yes, solar panels can be affected by temperature. High temperatures can cause a decrease in their efficiency and overall power output. However, some modern solar panels are designed to handle higher temperatures more effectively, minimizing the impact on their performance.
- Q:Why can not the solar panel load directly?
- Solar panels (also known as solar modules) are the core of solar power systems and the most important part of solar power systems.
- Q:Do solar panels require regular maintenance?
- Yes, solar panels generally require regular maintenance to ensure optimal performance and longevity. This includes periodic cleaning to remove dirt, debris, and snow, as well as checking for any possible damage or malfunctioning components. Additionally, regular inspections and maintenance by professionals are recommended to identify and address any potential issues or inefficiencies.
- Q:How to make a simple solar panel?
- It's pretty basic, but I hope this helps!
- Q:What is the warranty on solar panels?
- The warranty on solar panels typically ranges from 10 to 25 years, depending on the manufacturer.
