3. Q: Do you provide free sample?
A: Usually we do not offer free sample
4. Q: Could you print our company LOGO on the nameplate and package?
A: Yes, we can do that.
- Q: Can solar panels be installed on assisted living facilities?
- Yes, solar panels can be installed on assisted living facilities. In fact, installing solar panels on such facilities can be a great way to reduce operating costs, promote sustainability, and provide a clean source of energy.
- Q: The voltage and power problems of solar panels
- 3, charge 12V battery when the power is really small, if it is a normal controller, then the equivalent of 18V voltage in the charge, probably 18 x (240 / 30.2) = 143w solar panels.
- Q: What is the principle and structure of solar panels?
- solar controller: the role of solar controller is to control the working state of the entire system, and the battery played a charge protection, over discharge protection role. In the larger temperature difference, the qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch, time control switch should be the option of the controller;
- Q: im making an energy efficiant house for science class and i need to price the house. im putting solar pannels on the roof and would u please tell me how much they are per like 2 sq. feet of a pannel?
- Completely self-efficient and autonomous??? Forget it. Too expensive. It's only worth if you use like 8 lights (2-20w) about 4 hours a day, a fridge, a tv about 4 hours/day and basically nothing else or a few low consume stuff. Forget about microwaves, dryers, or other stuff. Too much watts. And that would cost you no less than 5000-6000$. You need panels (about 4 or 6 20w would suit maybe), 2 batteries (about 600Ah at least), inverter(500w/24v) and a regulator, lets say a 30A one. Just stick to normal energy supply. A single 20w panel may cost about 750$ at least.
- Q: I'm going to pitch an idead to my school about switching to Solar Energy. What are positive and negative effects of the solar panels?Also what is the cost for installing them into a highschool?How much would the electricity bill decline afterwards?
- Solar panels can convert sunlight into electricity which can be used in daily life,solar panels utilize sunrays,it doesn't discharge any polluted gas,it is environment friendly,it is also cost effective,you can make money by sell the surplus electricity to your country, On question is that solar panles have to be use in where sun is abundent.
- Q: Thinking about getting a solar panel installed but i'm worried about getting the govt. rebates. There is a Federal Tax credit and a State of Florida rebate and i'm wondering what the time frame is for getting the rebates. Has anyone gotten a solar panel installed recently that could give me more info.Thanks!
- In case you hadn't heard the state is broke.
- Q: How do solar panels impact the local economy?
- Solar panels can have a positive impact on the local economy in several ways. Firstly, the installation and maintenance of solar panels create jobs, boosting employment opportunities in the area. Additionally, the use of solar energy reduces dependency on traditional energy sources, which can lead to lower energy costs for businesses and residents, freeing up more money to be spent locally. Furthermore, solar panel installations often require local partnerships and suppliers, supporting local businesses and stimulating economic growth. Ultimately, the adoption of solar panels contributes to a more sustainable and resilient local economy.
- Q: Solar panel for battary charging
- What you are stating is that the battery you have will operate the UPS for about 2 hours before it is drained past the point of no return (technically 2.82 hours, but that would be a dead battery - most well-designed UPS systems cut off when the battery gets below about a 30% charge so that battery is not damaged. Lead-Acid batteries have about a 0%/month self-discharge rate if there is no load connected. The very best systems are as low as 3%, the worst are over 20% - and all at a 'normal' temperature. So, you will need a maintenance charger of about ten (0) watts or so - amp will be more than enough. And about any solar panel will handle that much with the proper charging connection.
- Q: For example, how many large solar panels would you need to operate a greenhouse with lighting for simulate sun during cloudy weather, a scheduled sprinkle system and other such things?I'm looking for a very in depth answer.
- if you are talking electrical solar panels, they are rated in watts they generate in full sun. usually these panels are used in tandem with batteries, so they charge up during the day and the batteries hold a reserve of power for later use. If you figure 8 hours of useful sunlight per day, then a 40 watt panel will light a 40 watt bulb for 8 hours. you can also measure capacity in watt-hours. this would be 40x8 = 320 watt-hours. the general method is to determine how much electricity demand you have over a 24 hour period to get the total watt-hours. then divide that by the watt-hour capacity of one panel to get the number of panels needed.
- Q: Is it as simple as buying the panels, an inverter and plugging it into a wall-socket, assuming it would just send power back into the outlet and supplement my house's electrical usage, or... Is it not that simple?Remember, I'm talking about a SMALL system, and I don't care how little power it'd make, or how uneconomical it would be.
- If I were to assume you could (and I don't) you'd be back feeding voltage into your breaker and probably ruin it. Or worse, start a fire somewhere on that circuit. Not to mention the need to match the Hertz AND the signal. Short answer is No, you can't do that. Not because of code - but code wouldn't allow it anyway, but because it is foolish and beyond dangerous - it's a guaranteed disaster. Hope this helps. ??? —
