In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served.

Q:Do solar panels increase property value?: Yes, solar panels do increase property value. Multiple studies have shown that homes equipped with solar panels tend to sell for higher prices compared to similar homes without solar panels. The added value comes from the potential savings on energy bills, the positive environmental impact, and the increasing demand for sustainable energy sources.

Q:Can solar panels be installed on a shopping mall or retail complex?: Yes, solar panels can be installed on a shopping mall or retail complex. In fact, many commercial buildings have already embraced solar energy as a way to offset their electricity consumption and reduce their carbon footprint. By installing solar panels on rooftops or parking structures, shopping malls and retail complexes can generate clean and renewable energy, leading to cost savings and environmental benefits.

Q:I have the wattage of solar panel but i dont know about the voltage amp; current rating of it. Plz explain me about the voltage rating of solar panel.: The voltage rating and current rating are part of the specifications for the panel. You will have them listed on the spec sheet. The voltage number is usually the open circuit voltage of the panel, the voltage with no load. The current number is the short circuit current of the panel. In use, you need special electronics, called a Maximum Power Tracker (MPT) controller, which adjust the load to get the most power from the panel, and adjust the voltage output via a DC-DC converter to the optimal conditions to charge the attached battery. how to take batteries as per solar wattage ? sorry, don't understand this.

Q:I have four power packs for solar lights. They have 3 AA .2volt batteries of 2450 mAh capacity installed in series for a total supply voltage of 4 volt maximum for the lights. I want to charge all four packs at once off a single 6 volt solar panel. With the four packs wired in parallel, what capacity output (wattage) panel do I need to charge the batteries in an 8 hour day?: 325 mAh+ losses so maybe 3.2Ah to 3.5Ah.

Q:Are solar panels easy to maintain?: Yes, solar panels are relatively easy to maintain. They require minimal upkeep, with regular cleaning to remove dust and debris for optimal efficiency. Additionally, occasional inspections to check for any damage or shading issues may be necessary. Overall, the maintenance requirements for solar panels are straightforward and manageable.

Q:What in the solar panel wares out so that the panel can not convert the suns energy to electric energy? Please post were you get answers.: The plastic covering degrades slowly and becomes more opaque, The metal current carrying parts corrodes over time. The metal frames corrode but can be repaired. The photovoltaic cells also degrade over time from exposure to ozone and heat that builds up in the panel.

Q:Also, what's the solar panel's rate of producing electricity?: Solar panels are not nearly as energy productive as natural gas. Case in point how many natural gas fired calculators do you have on your desk? or how many solar fired fireplaces do you know of? Solar panels are a great complement to natural gas/fossil fuel burning sources of fuel though. The more energy you consume from renewable sources of energy (i.e solar, wind, etc) the less you are consuming from non-renewable sources such as natural gas. Solar panel's rate of producing electricity depends on many different variables. Are the panels in direct sunlight? (with no trees or shrubs blocking the panels) There are panels out there made by Kyocera for example that are 85 watts, 65 watts, 50 watts. You should talk with a Professional about this. Look into Sun Electronics as I know that their website has a solar calculator and other helpful tools for interested parties. Good Luck

Q:How are solar panels installed?: Solar panels are typically installed on rooftops or open spaces using metal frames or mounting brackets. The process involves anchoring the panels securely, connecting them in a series or parallel configuration, and wiring them to an inverter that converts the DC electricity generated by the panels into usable AC electricity. Additionally, a solar panel installation may require making electrical connections to the building's electrical system and installing a net meter to measure the energy produced and consumed.

Q:I want to add solar panels to my home. I was looking online and it seems there are so many different kinds! How does it hook up to the electrical grid? How much do I need for a 2000 sf home?: This is still not a trivial project, although it is getting easier. The usual way to do this is to contact professional installers for free quotes. In the process of getting the quote, you'll learn what considerations go into sizing a solar system. They'll look at your energy usage, and also whether your house has a good, clear, south-facing roof that doesn't get shaded during the day. They'll also look at your electrical panel to see whether they can hook right up, or additional work is needed. There are rumors of companies like Akeena planning to sell panel kits in Home Depot (in areas that Akeena does not directly serve). The idea would be that a pro installer would pick up the kit there, but a highly skilled homeowner might be able to make it work. A permit will probably be required by your jurisdiction, but that's no different than applying for any other construction. And you'll have to inform your power utility in advance, which may or may not be routine, depending on how often people connect solar in your area. If you want to see how we connected our system, a link is below. I did not really save money by doing it myself. That's because pro's can get better prices on the panels, which makes up for the labor cost.

Q:Can solar panels be installed on ground-mounted structures?: Yes, solar panels can be installed on ground-mounted structures. Ground-mounted solar panel systems are commonly used when there is limited space on rooftops or when the optimal orientation and tilt angles cannot be achieved on a building's roof. Ground-mounted structures provide flexibility in panel placement, allowing for optimal sun exposure and ease of maintenance.
