- Q:I am researching several solar panels to install in my house. I would like to use a 40 watt panel to connect, through a solar battery controller, to a battery or two. I would then like to use the solar panel (40 watts) to charge the battery(ies) for emergency use. Once charged, and when needed, I would like to use the battery(ies), 2 volt deep cycle, to power several LED lamps. Since I am new to solar power I had several questions...Is a 40 watt panel strong/large enough to charge a 2 volt deep cycle battery or two?How long would it take to charge one of these batteries?What would be the expected cost to purchase necessary supplies? (With the solar panel, battery controller, and MC4 cabling I've found I have an expected cost of roughly $00.00 with batteries)Would this be difficult for someone with little experience in this field?
- There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
- Q:what parts and tool do i need to build and connect a solar electric panel to my home
- you need to buy, not build. Just to put the parts together correctly requires a lot of experience, not something to be done by someone with no experience. And this is a major project, with lots of decisions before you start. how many watts? how many hours of sun do you get per day? worse case? Do you have a space to put the array where it can get sun all day with no shade? grid tie or not? how many batteries if not grid tie? if no grid tie, how long do you expect the batteries to last during a long period with no sun? And finally, how much money do you want to spend. for a good sized system expect to pay US$20k to 50k
- Q:How do solar panels affect the roof's structure and integrity?
- Solar panels can have a minimal impact on the roof's structure and integrity. When properly installed, solar panels do not pose a significant risk to the roof. However, it is important to ensure that the installation is done by professionals who follow industry standards and guidelines to avoid any potential issues such as leaks or damage to the roof. Additionally, the added weight of the panels should be considered, but modern mounting systems are designed to distribute the weight evenly, minimizing any strain on the roof.
- Q:Can solar panels be used in hot climates?
- Yes, solar panels can be used in hot climates. In fact, solar panels actually perform better in higher temperatures as they rely on sunlight rather than heat to generate electricity. However, excessive heat may slightly reduce the efficiency of the panels, but modern solar technology is designed to handle and adapt to varying weather conditions, including hot climates.
- Q:Can solar panels be used for powering outdoor signage?
- Yes, solar panels can be used to power outdoor signage. Solar panels convert sunlight into electricity, providing a sustainable and renewable energy source for outdoor signage. This eliminates the need for traditional electricity sources, reduces energy costs, and minimizes the environmental impact.
- Q:How do solar panels affect the property's energy efficiency rating?
- Solar panels can significantly improve a property's energy efficiency rating. By harnessing the sun's energy, solar panels generate electricity that can power the property, reducing reliance on traditional energy sources. This results in lower energy consumption and decreased carbon emissions, both of which positively impact the property's energy efficiency rating.
- Q:Can solar panels be used for heating swimming pools?
- Yes, solar panels can be used for heating swimming pools. Solar thermal panels, specifically designed for pool heating, capture the sun's energy and transfer it to the pool water, increasing its temperature. This renewable and eco-friendly method is a popular choice for pool owners looking to save on energy costs and reduce their carbon footprint.
- Q:Can solar panels be used for powering public transportation?
- Yes, solar panels can be used for powering public transportation. Solar-powered buses and trains are already in use in various cities around the world. These panels capture sunlight and convert it into electricity, which can be used to power the vehicles' motors, lighting, and other systems. This renewable energy source helps reduce carbon emissions and dependence on fossil fuels in the transportation sector.
- Q:I just connected my 5 Watt 2V solar panel directly to my 300 Watt 2 inverter. It worked for about 2 minutes then it popped (sparks, smoke etc)! What the hell did I do wrong? I thought the solar panel was 2 volts? Can someone with experience with these things help me out?
- 2v okorder staff
- Q:i need to know wat the parts of a solar panel are.
- For a photo electric system you need 3 basic things. Photo voltaic Solar panels the quantity determined by you need and a charge controller for the cells they are rated by current. Batteries the quantity determined by your needs. Last an inverter to convert 2 volts DC to 20-220 AC. The size shown in watts is determined by you needs. If you plan to use it all the time you will have to have piece of equipment usually part of the inverter to sync the inverter up with the public utility and any power you don't use gets sold to the power supplier. That our a manual switch which will not allow you to sell unused power to the power company. If you are thinking about this do your home work and if possible contact it out. This is not a good first time DIY especially since you are asking this question. No offense. Otherwise you will need to do some reading and studying. But no matter what there are parts that an electrician will have to do by law and you may need a permit depending on where you live.
