FAQ:

Solar panel refers either to a photovoltaic (PV) module, a solar hot water panel, or to a set of solar photovoltaic modules electrically connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells. Solar panels can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q: Can solar panels be installed on a residential community or housing development?
Yes, solar panels can be installed on a residential community or housing development. In fact, many residential communities and housing developments are embracing solar energy by incorporating solar panels into their buildings or providing shared solar systems for the residents. This not only helps to reduce the carbon footprint, but also allows residents to save on electricity costs and increase the overall sustainability of the community.
Q: I am researching several solar panels to install in my house. I would like to use a 40 watt panel to connect, through a solar battery controller, to a battery or two. I would then like to use the solar panel (40 watts) to charge the battery(ies) for emergency use. Once charged, and when needed, I would like to use the battery(ies), 2 volt deep cycle, to power several LED lamps. Since I am new to solar power I had several questions...Is a 40 watt panel strong/large enough to charge a 2 volt deep cycle battery or two?How long would it take to charge one of these batteries?What would be the expected cost to purchase necessary supplies? (With the solar panel, battery controller, and MC4 cabling I've found I have an expected cost of roughly $00.00 with batteries)Would this be difficult for someone with little experience in this field?
Whats the size of battery ? The time needed for your 40Watts panel to fully charge a battery depends on the size of battery. Usually battery size is mentioned in Amp-Hours (AH).
Q: I had someone quote me for solar panels on my house but I can't afford it. They were talking about how I have enough room and the perfect location to put many of them and actually get paid for it. I have about a half acre that is tiered and points in the correct direction for them to get pretty much the full day sun. Additionally, I live in so cal where it is sunny most of the year. Does anyone know if solar companies will lease or install them to get the payback? I would be happy to allow them to use the land just to cover my electrical expense and they could have any payback.
Hi, In the UK solar companies will fit them for nothing. The company gets the government allowance (called feed in tarrif FIT) and you get the benefit of the reduction in your power bills. The solar company make better money than the householder,BUT if the householder is in most of the day it could be most beneficial if the energy is used while the panels are generating, this means the householder is not paying for the power from the grid. If the householder works normally from 9 to 5 then there is less advantage in terms of getting free power from the panels. Best Wishes.
Q: If you want to instal solar panels...how often do you have to replace them?
Expect a water heating panel to last about the same as a water heater, 0 to 5 years. Actually, my brother's system is coming up on 5 years, and is not giving trouble yet, so maybe technology has advanced. I have actually never personally known of anyone replacing a solar electric panel due to wear-out. I have heard of occasional replacements due to accidents, including natural disasters like lightning strikes. And one brand of panels had manufacturing defects around the year 2000, but that manufacturer owned up and replaced those free of charge to their customers. A standard warranty on a solar electric panel nowadays is 25 years.
Q: There are places in the US where it is sunny almost all the time, like the southwest. But if we covered an area of the Sahara with solar panels, the sun exposure with the area would generate enough energy for the whole US at least. Plus, I would imagine it would be a great source of income for those countries.Why isn't this a topic under discussion or even mentioned between countries' governments/in Congress/in politicians' viewpoints?
Good question. One of the reasons is the greed of manufacturing companies. No matter the profit margin of the product, they seem to want to charge so high a price that the break even point is ten years down the road, so the true savings are few. The cost of solar panels should have dropped way lower than they have by now. I believe that the political correctness of the product will tempt the manufacturers to keep the prices artificially high. One other answerer is right, the panels are very fragile, and damage would destroy the investment, so new inroads need to occur in technology to protect the panels from damage. Somewhere in the middle is a profit for the manufacturers, and savings for the consumer. I hope we find that middle-ground soon.
Q: Can solar panels be installed on a pergola or gazebo?
Yes, solar panels can be installed on a pergola or gazebo. Both structures provide an ideal location for solar panel installation, as they offer unobstructed exposure to sunlight. Additionally, integrating solar panels into a pergola or gazebo can enhance their functionality by providing shade, while generating renewable energy at the same time.
Q: I don't remember what number exactly but it's in the single digits. This number represents how efficient solar panels are at capturing the sun's rays and converting it into electricity.Why?
The latter link has a decent explanation, if not a bit technical: One of the most fundamental limitations on solar cell efficiency is the band gap of the semiconductor from which the cell is made. In a photovoltaic cell, negatively doped (n-type) material, with extra electrons in its otherwise empty conduction band, makes a junction with positively doped (p-type) material, with extra holes in the band otherwise filled with valence electrons.
Q: Does anyone know the earnings potential for the actual fitter of pv solar panels,and the electricians earnings.ty.
it depends on your solar panel, but you can sure supply most if all of your electronics and electric stuff in your house on a sunny day. If you want to know exactly how much power it supplies and how much $$ you can save you simply have to calculate how much power your home consumes per day/month. I know of people totally reliable on solar power for their home and I too will put solar panels on my home one day.
Q: are there solar panel that work without the sun?
There cannot be a solar panel which works without sun light. But solar panels can work without sunlight. For example you would have seen the battery less calculators which work on solar power. they work in the night too with enough light coming from the bulbs in the room. So the answer to your question in yes. But for generating power we have to have a source which is free and we cannot put the panel in lighted area, which will make is not economical since the nett power obtained will be negative.
Q: Can solar panels work at night?
No, solar panels cannot generate electricity at night as they rely on sunlight to produce power.
