SITE SELECTION

In most applications, the PV modules should be installed in location where there is no shading throughout the year. In the Northern Hemisphere, The PV modules should typically face south, and in the Southern Hemisphere, the PV modules should typically face north. Please make sure that there are no obstruction in the surroundings of the site of installation. Take proper steps in order to maintain reliability and safety, in case the PV modules are used in areas such as: Heavy snow areas/Extremely code areas/ Strong wind areas/Installation over, or near, water/ Areas where installations are prone to salt water damage (*)/Small islands or desert areas.(*)

If you are planning to use the PV modules where the salt water damage may be possible consult with CNBM local agent first to determine an appropriate installation method, or to determine whether the installation is possible?

TILT ANGLE

The title angle of the PV module is the measured between the PV module and a horizontal ground surface. The PV module generates the maximum output power when it faces the sun directly.

For the standalone systems with a battery where the PV modules are attached to a permanent structure , the tile angle of the PV modules should be determined to optimize the performance when the sunlight is the scarcest. In general, if the electric power generation is adequate when the sunlight is the scarcest, then the angle chosen should be adequate during the rest of the year. For grid-connected installations where the PV modules are attached to a permanent structure, it is recommended to tilt the PV module at the angle equal to the latitude of the installation site so that the power generation from the PV module will be optimum throughout the year.

 

Q:I would like to know if I had a mobile kitchen could I power it from solar panels mounted atop the vehicle (truck).(to power electric kitchen equipment, i.e. stove, deep fryer.), instead of propane…could I possibly connect the solar panels to a battery to save my generated electricity? If solar panels would not be enough power could a small windmill suffice…?
The best way to find out is to determine the wattage of each piece of equipment you want to use and how many hours you want to use those pieces of equipment. Finally, calculate the total number of Watt-Hours you need at minimum. Then you need to research solar panels or mobile wind mills (they need to be pretty huge to get a decent amount of energy I think, so solar power is probably the way to go). You will need to figure out the efficiency of the solar panels, the size of the array, how you will turn it or if you will turn it at all (to face the sun to get the maximum energy input, or maybe to use mirrors so you don't have to turn it. Once you find a good configuration for your mobile kitchen, you need to calculate if the Watt-Hours you will generate on an average day (with average weather) is enough to power the equipment whose energy requirements you previously calculated. Then you have to keep in mind that some days will have no sun, and you may not be working on some days, but you can still capture sunlight. For each case, a large battery array will be required. If you had a guage on that array, you could also hook it up to the a small generator in case you need immediate power. It's an eco-friendly process, but the initial cost is high and it requires a lot of research and planning. This is why most people do not do it--not because they don't want free energy from the sun, but because it's not easy to start collecting that energy in an efficient way. Sorry I couldn't give you more specific numbers, but a solar panel sales agency should be able to estimate whether or not you could do it (they'd probably set it all up for you too). ^_^
Q:I own a townhome in the Phoenix area (my power company's SRP, if that makes a difference). Phoenix is a great place for solar. I could probably save money, in the long term, if I got some solar panels.But I am currently extremely broke, so I can't buy solar panels unless I will more or less immediately be paying no more than I am now per month, with little or nothing down. And most of the solar leasing places won't work with me, because (as is common for townhomes) I don't technically own my roof. I have permission to put things on it, but the property management people (or whoever actually owns my roof) won't sign the lease or whatever.Anyone know of either a way to buy solar panels without paying significantly more per month than I already do for electricity, or a solar leasing company that can work with the restrictions I have?
The big problem is that you cannot force the homeowners association to do anything. I live in a condo with a HOA. We have outside parking spaces. The goonies won't let people run electric lines to parking spaces to charge electric cars. Several years ago, residents had to sue the HOA in court because they would not allow satellite dishes on buildings. The HOA lost. You don't have money to pay an attorney so you are out of luck.
Q:OK so how do these solar panels supplement the AC from the grid? Like do they invert the output of the solar panels and sync two AC sources together? If so how and with what? Or do they convert the AC from the grid to DC and then supplement and then invert it? If so how and with what? Thanks
you have had 2 good solutions already yet once you go with greater advantageous examining on photograph voltaic panels and technical suggestions on the factor components of a photo voltaic panel setting up take a seem on the link under which has over one hundred quite good articles on photograph voltaic.
Q:) what is absolutely needed to hook up a solar panel to grid tie, what permits and/or inspectors are needed?2) if we know how many KWH's we use per month, do we just divide by number of hours per month to find out average KW usage?3) what is an estimated ratio of DC to AC transformation/convertion @ 30 C?4) do the solar panel voltages have to be the same? what would happen if the voltage going into the house is greater/lower than that of the house's defualt voltage5) for added chance of getting 0 pts add some contrators that do business in ohio for installing solar panels or sell them
The okorder The reference section has all the formulas you are looking for and there is a list of dealers by state, plus various state rebate information. Yes, you can hook up different panels to the same system. There are special controllers that regulate the voltage. I'm more of a hands on nuts and bolts guy so I can't help you with the formulas and engineering explanations. Another great place to get information is Home Power Magazine. You can get the issues online or in print. Thanks for going solar!
Q:So how does a solar panel work? Where does the energy get stored in? How much does one cost for a small 2 family home? How much money would we save on electricity?
The first thing to understand is that there is nothing complex about a solar panel. It is nothing more than a collection of solar or PV cells on a board that is fitted to the most appropriate part of your home, generally on the roof. There are guides out there that teach you how to build a solar panel and a windmill for just $50, and it’s very easy to make. Best of all, you can save 70% or more on your energy bill, adding up to thousands of dollars each year in savings. I reviewed both free guides and paid guides and have come up with our top to Build your own solar panels.
Q:What is the purpose of solar panels?
The purpose of solar panels is to convert sunlight into usable electricity, providing a clean and renewable energy source for various applications such as powering homes, buildings, and even vehicles, while reducing dependence on fossil fuels and mitigating environmental impact.
Q:I want to be more green and if I get the panels will I still have a regular electric bill?
The most cost-effective solution, which the vast majority of new installs use today, is solar alongside the regular power company. That way, you need no batteries, and if the solar array isn't producing enough at any given time, you draw from the electric company. When the array is producing more than you need, instead of just throwing that power away, the power company buys it (usually). In short, yes, you will still have an electric bill, but a smaller one. On our house, the electric bill was a little less than $5 a month, with an end-of-year settlement of an additional $2. How much does it cost? Unfortunately, that's like asking how much personal transportation costs. Some people need a van to transport the kids to soccer, some may get by with a motorcycle, others may need only a bicycle. The best thing is to contact a professional installer to get a quote based on your location and electrical usage. Solar electric does not make financial sense in all areas. Our array cost $2,000 but don't use that as a guide. Yours might be 0 times that, or half that, depending on your area and needs.
Q:How do solar panels affect the energy independence of a building?
Solar panels can greatly enhance the energy independence of a building by converting sunlight into electricity. By generating their own clean and renewable energy, buildings with solar panels can reduce or even eliminate their dependence on traditional energy sources like fossil fuels or the grid. This not only reduces the carbon footprint but also provides a sustainable and reliable source of power, ultimately granting greater energy independence to the building.
Q:Can solar panels be used for powering a water treatment plant?
Yes, solar panels can be used to power a water treatment plant. Solar energy can be harnessed to generate electricity, which can then be used to power the various processes involved in treating and purifying water. This renewable energy source provides a sustainable and environmentally friendly solution for powering water treatment plants.
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!
this is according to the load, that is to say, how many electricity do you need in one day.
