Q:I need to build a battery array to use with my solar panels I just bought. I want to be able to store enough energy to be draw from it at night, possibly around the clock. Is there a down side to using the deep cycle battery I bought from autozone and 6 or 7 more just like it, or do I need to get some other battery?
There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
Q:Has anyone had any experience building their own solar panels for home use? I have seen on the news lately that people are utilizing solar panels to power their hot water heaters to save on their power bill.
Hey David, yes, we have built plenty of them. If you are into the do it yourself world, the easiest type to build is the Batch Preheater type. What you need is an old water heater, something small, like an under counter model, 0 to 30 gallons in size. It has to be one that hasn't rusted out yet and started leaking. We stopped at a local plumbing place in town, they are always throwing out units they have removed from homes because the new owner wants a larger unit, or gas versus electric, and so on. He sold us a pretty recent model for $0. Take the water heater home, and strip off the outer metal housing and all the insualtion so all you have left is the tank. Clean it up, and paint it with black paint. Now build a wood enclosure, something the size of a dog house that your tank will fit inside of. Use a glass panel for one side of the roof. What works best is an old window pane someone is throwing out that is about the right size, then build your dog house to fit it. When it's done, put some styrofoam insulation panels around the back and side walls to keep the heat in when the sun shines on it, then mount your tank inside. Put your dog house someplace in the sun, run the cold water that normally feeds into your water heater into the tank (in the cold inlet side), then run a pipe from the outlet of the tank to your regular water heater. We have one just like this installed in the northern midwest, it works great about 7 months of the year. Usually in the summer if it's about 75 degrees outside, the water comes into the house at around 00 degrees, then the regular water heater only needs to add another 25 degrees to the water to finish it off. Since the water starts out at about 56 degrees, the solar preheater ends up doing about 65% of the work. In the winter, we simply drain the tank and lines to and from it, and route the cold water directly to the regular water heater. There are some designs on line, try googling, Batch Water Preheater. Take care, Rudydoo
Q:A local air conditioning company is advertising combining their (newly installed) central air conditioning system for homes, with roof solar panels. They say that the combination MAY reduce your electric bill. Nothing I can see to back-up their claims. Hmmmmm. And they offer, if you can get it; central air conditioning that runs on natural gas. Again, possibly cheaper than using electricity.Has any one actually tested to find out if solar panels and/or natural gas DOES, or DOES NOT save you any money to make it worth the bother?
Don't do it! It takes years to get your money back. Your better to put the money into insulation and or buying geo thermal unit. I knew someone who install solar panels on his roof to generate hydro and he didn't notice much of a change on his hydro bill and then he had roof problems . Central air units in last 2 years have become very efficient . Almost half the hydro of ones 0 years ago. If you can afford buy a geo thermal unit. It uses the heat of the ground in the winter 2 heat your house during the winter and the coolness of the ground to cool your house. They aren't cheap though. If you plan on living in your house for more than 0 years and have the room in the yard to install then go for it. No how you slice it though AC units use way more hydro than solar panels can produce. You would need about half a football field with a huge battery storage system to run a AC unit. When a company states you might on hydro I would stay away. Also remember they do not tell you about the costs of the upkeep on the solar panels and converter and batteries
Q:I want to install solar panels in my roof and most installers don't recommend any particular brand. Do you have experience with any particular brand that has worked for you or anybody you know? Does the brand of the panel make a difference?
I didn't research this. I do know that you must install them on the side or area of the roof that receives the most Sun all day. You can get information at stores like Lowes or HomeDepot.
Q:Hello everybody, the area we are living has energy crises with no electricity available most of the time. What I am thinking is to buy a solar panel with other required accessories. Please note we have normally long sunny days most of the time during a year.Please advice installing solar energy system would supply energy 24/7? I have a television, a dvd player, a fan, 4 energy saver lights (2 watt each) and a laptop. Please also advice the specifications for the system to be installed and the points I need to ensure at the time of purchase. I think of buying a solid battery (not acidic battery)The forum is open for your kind suggestions.Thanks!

Q:Can solar panels be used in areas with high levels of wind-blown debris?
Yes, solar panels can be used in areas with high levels of wind-blown debris. However, it is important to ensure that the panels are properly installed and maintained to withstand the impact of debris. Regular cleaning and inspection may be required to prevent any obstruction or damage to the panels, ensuring their optimal performance.
Q:Can solar panels be installed on a pergola or awning?
Yes, solar panels can be installed on a pergola or awning. In fact, these structures can provide an ideal platform for solar panel installation, as they offer ample space and exposure to sunlight. Additionally, installing solar panels on a pergola or awning can help to maximize energy production while also providing shade and protection from the elements.
Q:Can solar panels be used for powering electric gates?
Yes, solar panels can be used to power electric gates. Solar panels convert sunlight into electricity, which can be stored in batteries or directly used to power various devices, including electric gates. This allows for a sustainable and environmentally friendly way to operate electric gates without relying on traditional electrical grids.
Q:please help me
Photovoltaic cells work because of the photoelectric effect. However, a solar panel can actually be using several different technologies that have the same common effect of generating electricity when the sun shines on them.
Q:how to market solar energy products?
You'd better build some sample project. For e.g, if you mean solar water heater, install one pc on your roof, and make it generate hot water, and tell people about it.
