This also contains safety information you need to be familiar with .All the information described in this manual are the intellectual property of CNBM and based on the technologies and experiences that have been acquired and accumulated in the long history of CUSTOMER. This document does not constitute a warranty, expressed or implied.
CUSTOMER does not assume responsibility and expressly disclaims liability for loss, damage, or expense arising out of in anyway connected with installation, operation, use or maintenance of the PV modules. No responsibility is assumed by CUSTOMER for any infringement of patents or other rights of third parties that may result from use of PV module.
CUSTOMER reserves the right to make changes to the product, specifications or installation manual without prior notice.
WIRING
To ensure proper system operation to maintain your warranty, observe the correct cable connection polarity(Figures 1&2) when connecting the modules to a battery or to other modules. If not connected correctly, the bypass diode could be destroyed.
PV modules can be wired in series to increase voltage. Connect wires from the positive terminal of one module to the negative of the next module. Figure shows modules connected in series .

- Q: Hi. I need to build a solar panel for a project. it should be able to light a 60 watt light bulb. also, it should be about 3x3 ft if it is 50% efficient. if anyone knows any websites or can help me, please answer! thanks.
- I don't have any practical experience building solar panel arrays to power a given device, but allow me to make this observation. Solar cells, when exposed to sunlight, will each generate a given amount of power (watts), and by wiring these in series, you will increase the wattage. Now, a panel three feet square will give you a certain amount of power, provided all the cells are wired correctly in series, and it may not provide enough juice to light the bulb. You can work around this by adding a step-up transformer (which takes the incoming power and boosts it to the desired level for output, with no moving parts). Voila! You've illuminated your bulb. I will admit, though, you'll have to do some math to determine what you need. A search on the Web will help you find the formulae and other information you'll require. Good luck.
- Q: I am curious about how much of the energy that a solar panel of a given size and capacity will produce in it's lifetime, and what fraction of that energy was required to produce it in the first place?
- At present the technology to create silicon solar cells is incredibly energy intensive. It is not logical to compare the cost of oil to the cost of a solar cell because they are not priced according to energy input. Oil has a strong advantage in that it is concentrated solar and geothermal chemical energy that has accumulated over millions of years. The price of oil does not reflect its energy content, but the cost to retreive it. Electrical energy used to produce a Photovoltaic cell is not priced in any proportion to oil. By some calculations it will take about 50,000 KWh of energy produced by the PV cell before it can recover the energy used to manufacture it.
- Q: was looking at a few different sites, here is one of them
- Building your own panels can be an interesting experiment, but if you are looking for solar panels to provide significant, consistent output, you should buy factory made ones. I get lots of calls from people who built their own panels and get a fraction of the advertised output from them. Plus, factory built panels will last 40 - 50 years, with a 25 year warranty, how sure are you that you can build something that can withstand the outdoors for that long? The price of panels has dropped a lot this year, plus with rebates and tax credits, it's getting more affordable.
- Q: Can solar panels be installed on rooftop gardens or green roofs?
- Yes, solar panels can be installed on rooftop gardens or green roofs. In fact, combining solar panels with green roofs can provide numerous benefits such as maximizing energy efficiency, reducing heat island effect, and enhancing biodiversity. It's a sustainable and innovative approach to utilize rooftop spaces for both renewable energy generation and environmental conservation.
- Q: Can solar panels be installed on a hospital or healthcare facility?
- Yes, solar panels can be installed on a hospital or healthcare facility. In fact, many hospitals and healthcare facilities are increasingly adopting solar energy systems as a way to reduce their carbon footprint, lower energy costs, and increase energy independence. Solar panels can be installed on rooftops, parking lots, or even as ground-mounted systems, providing clean and renewable energy to power the facility's operations.
- Q: I hooked up a 2V solar panel to a small relay. The relay switches at 9V. When I have light shining on the panel it puts out aorund 3-4V, but when I hook it up directly to the relay it drops to V and doesn't switch the relay. Why? and How do I fix it?-2V Mono-Crystalline Solar Panel -JWD 7 4 reed relay
- Your solar panel output too little current that cannot be used to power the relay. Change the panel into 2V 500mA type shall work.
- Q: They absorb solar heat and transform it into electricity, so there should be less heat left to warm the planet. Shouldn't we at least plaster all the world's deserts with them?
- The opposite - they heat the Earth up. The ground underneath might be brown or green or sand. The solar panels are Black. They absorb more radiant energy. Solar electricity is energy and somewhere down the wire will produce heat. Solar's saving grace is that it has the same heating effect year after year. But greenhouse gasses have a cumulative effect. The excess gasses produced in year one are added to the gasses in year two, etc. For instance say the heating of soalr cells is 5 times (5s) that of greenhouse gasses (g). Year - Total Heating - 5s + g 2 - 5s + 2g 3 - 5s + 3g 4 - 5s + 4g 5 - 5s + 5g 6 - 5s + 6g 7 - 5s + 7g 8 - 5s + 8g 9 - 5s + 9g 0 - 5s + 0g etc... In 50 years you have 50 - 5s + 50g
- Q: I was watching an idiot abroad, and I saw a family that lived in tent like huts, with no plumbing. And they had a solar panel, now if they can afford it, I know I can. Where do you get cheap ones?
- I okorder Hope this helps.
- Q: Can solar panels be used for camping or outdoor activities?
- Yes, solar panels can be used for camping or outdoor activities. Portable solar panels are designed to be lightweight and easily transportable, making them ideal for powering electronic devices and charging batteries in remote locations. They harness the sun's energy to generate electricity, allowing campers to have a reliable and sustainable power source while enjoying the outdoors.
- Q: Need solar panel info with dimensions and also the total cost of the whole equipment for setting up of the required solar panels for a 2-story home
- Please excuse my bluntness, but you are not ready to ask these questions. This is a very complex issue. The how many question depends on what you expect of the system. Are you attempting to be off the grid? If so the system will have to supply all of your electrical needs, including those at night. You would need batteries. If you will be on the grid and want to supply all your electrical needs, your system will have to average the total daily usage. This will vary from one season to the next, so you will need to find out your annual usage. If you just want to reduce your electric bill, you need to pick the acceptable installation cost, and work with it to determine what it will buy In your shoes I would do some studying. Check out solar panels in the green search box above, and on the Internet. This will help you ask questions that are easier for us to answer.
