Q:Can solar panels be integrated into building materials?: Yes, solar panels can be integrated into building materials. This innovative approach, known as building-integrated photovoltaics (BIPV), allows solar panels to be seamlessly incorporated into various architectural elements such as roofs, facades, windows, and even entire building structures. BIPV offers a dual function by serving as both a source of renewable energy and a structural component, enabling buildings to generate sustainable electricity while maintaining aesthetic appeal.

Q:Where can I find good instructions to build a cheap solar panel on my own?: There okorder /

Q:I need to be able to charge a 2v 7amp battery with a solar panel. I understand that the charge controller will keep the battery from over charging/discharging, but what I don't understand is the amps.The solar panel is rated at 5watts.The solar panel comes with a 2v 3amp charge controller but will I need to buy a 7amp charge controller and replace it with that for my battery pack? Please explain. Thanks in advance.: If it is a charge controller that is wired between the panel and the battery only, then a 3A rating is ample. The controller only has to handle the maximum current that the solar panel can output. The panel will have (or needs to have) an open-circuit voltage that is greater than about 4V in order to actually charge the battery, whose terminal voltage will rise above 2V as it charges. The panel's open circuit output voltage typically is about 7V. The 5W rating is at the maximum power point under the illumination of standard sun and at a specified temperature. That maximum power point probably is around 4V, which means the panel will deliver the following amperage to charge the battery: I = P/V = 5W/4V = 0.36A Since 0.36A is well below the 3A rating of the controller, the controller will not be overloaded when charging the battery. Some charge controllers also have terminals for connecting the load that you want to power. If that's the case, then the controller also needs to be rated to handle that load amperage or higher. If you were to connect a 6A load, then you would like to have say a 0A controller. Hope that helps.

Q:How do solar panels affect the property's energy efficiency rating?: Solar panels have a positive impact on a property's energy efficiency rating by generating clean, renewable energy. By harnessing sunlight and converting it into electricity, solar panels reduce the reliance on traditional energy sources, leading to lower energy consumption and costs. This increased energy efficiency contributes to a higher rating for the property.

Q:How much space is required for solar panel installation?: The amount of space required for solar panel installation can vary depending on factors such as the size and type of panels, the energy needs of the property, and the available sunlight. On average, a typical residential solar system may require anywhere from 100 to 600 square feet of roof space, but ground-mounted systems can also be an option for properties with ample land. It is best to consult with a solar installation professional to determine the specific space requirements for your particular situation.

Q:I have seen DIY software which explains everything for novices. Specifically, how to build your own solar panels and tie them into your home electrical system for about $00 in parts.Has anyone tried doing this? Was it easy?: Hi Mitch, Yes they are legitimate ans so much so the government will actually help you pay for them. Someone has already mentioned if you purchase them from your local solar panel installer they will not be cheap.They have come down in price a lot over the last couple of years. Yes you can build your own and no its not too difficult.You need to know in your own mind whether you just want to reduce your utility bill or come off the grid completly. The best solution is a combination of wind and solar power and yes you can build your own windmill as well and at the bottom her I will show you where to go to get easy non technical plans. Naturally the sun does not shine at night so your solar panels would not work then but windmills function 24/7 as long as there is wind. If you have nearby neigbours please be aware windmills do make some noise which might upset your neighbours and of course see if you need planning permission from the town. The solar panel plans show you how to set an 80w solar panel which of course would not be able to power your whole house,but once you have built one why not build loads more and each one will get easier to build. Wish you all the best.

Q:Polycrystalline solar panels are good or single crystal solar energy is good: From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.

Q:Online stores selling solar photo-voltaic generation kits gives specs indicating the power generation capability of the system. For example, Solar World Grid-Tie Solar Electric System with 245W Panels PV Powered PVP2000 Inverter, .2 to 2.4 kW. This seems to indicate that the system can generate .2 to 2.4 kW. Is that per day? Per month? I'm trying to calculate the return on investment, but can't because I don't know how much power a system such as this will generate in a month.: As Ed said, that .2 kW is an instantaneous rating in bright sun. The way to do this right is to consult the maps here rredc.nrel /solar/old_data/nsr... to find the number of equivalent sun-hours your location gets per day. Select, Average, Annual, Flat plate tilted south at latitude. A map will come up. For northern California, it shows 5 equivalent sun hours per day, for example. If the system is .2 kW, then .2 x 5 = 6.0 kWh of energy the system will generate per day, on average. That takes into account cloudy days, short winter days, long summer days, everything. The 2.4 kW system would give double that, obviously. But that's an example, based on a specific location. Phoenix would do better, Seattle would do worse.

Q:I live in the UK, I have no savings (so would have to take out a loan of about ?8000), I don't know how long I plan to stay in my house, I might want to move in a year or two to take advantage of a better job so I want to keep the option open of being able to sell my house without having to pay off the cost of having the panels fitted (which I probably won't get back on the increased value they add to my house).What are the main advantages of having solar panels?What are the pitfalls the ever so eager cold callers with quotas to fill don't tell you about?Basically is it worth having them?Thankyou.: Payback for your investment is 5-25 years, depending on sunny skies, durability of your system, rate of your utility company/taxes, and luck. If you have storm damage, accidents, or equipment failure, add that expense. It would be tough to get full value at the sale of your property, based on actual productivity (kwh produced) and relative condition/durability.

Q:I'm curious to know if the small solar panels on a calculator (ie TI-32) could produce a voltage similar to what is used in a single-use (disposable) camera, approximately 4V.: Wrong forum
