Q: I want to build a solar panel
Did okorder / . This will absolutely save yourself!
Q: when we say a solar panel has 20% efficiency, do we mean that it converts 20% of sunlight reaching it into electricity or that it converts 20% of visible light(which is only 7% of sunlight) into electricity?
Photo-voltaic solar cells use the visible light range (photons) for the conversion of sun's rays to electrical energy. The potential of solar radiation is ,353 Watts per square meter, but that is mostly a measure of heat, or infrared radiation. The visible light is actually a small portion of the spectrum. You have struck on a problem associated with photo-voltaic cells. Infrared radiation acts to heat up p-v cells (heat stress), causing them to be much less efficient. It would be interesting to see a hybrid p-v panel that is cooled with fluid or air running through it. This would increase efficiency of the p-v process while providing a heating source. This in turn could be used directly for heating or for production of electricity through a generator system.
Q: Can solar panels be installed on water pumps?
Yes, solar panels can be installed on water pumps. Solar-powered water pumps are a great alternative to traditional pumps as they harness energy from the sun to power the pumping system. This not only reduces reliance on fossil fuels but also makes these pumps more versatile and suitable for remote areas where electricity may not be readily available.
Q: What would these solar panels power? For instance, my energy bill shows 2035kWh for last month. How much would this remove from that if it outputted full power? Thanks!
note breath on the winds excellent answer is one quarter of one percent. See why houses aren't covered in solar panels? it's just not a real answer right now,. the rough rule of thumb is $0 per kWh ( for just the panels) you want to produce. You'd need $20,000 in panels and another 0,000 in controllers and inverters and batteries and who knows how much in installation.
Q: what is the average cost, for a single family home, to install solar panels? I live in CA.
I just got a quote for my place. It came out $8/Watt installed. The quote was for 24 - 20W panels. Dividing the total quoted price by the 24 panels comes out to $,750 per panel. This includes the complete system with the converter and cutoff switch to connect it to the grid. This is also a top-of-the-line system. There are cheaper systems with shorter life spans. My quote was for a system with a 30 year life expectancy. There is a Federal tax credit in 2009 of 30% that will bring the system cost down. There are also nice state tax incentives in CA.
Q: want to add solar panels to manufactured home, and we get a lot of snow up here in the NW. Wondering if it would interfer with the roof load.
A single hexagonal solar panel weighs around 0 to 2 pounds (see link). A conventional silicon solar panel might weigh 40 pounds.
Q: I want to be more self sufficient and get solar panels for electricity in a small house any tips will help. i need to know how many watts is enough and ect.
Unless you're very rich, you won't be able to afford solar panels that can meet the average demand of a home. In the US, the average demand for a home is 920 kwh per month, which amounts to 3,833 Watt panels if you assume 8 hours of usable sunshine and don't take into account your location. At current installation rates that's easily a $9,65 project. If you assume a 25 year useful life, it amounts to a return of 3.3% per annum at 0 cents a kwh not counting the costs of repair, insurance, the inverter, any fees to the utility for net metering if any etc. You would be better off putting $9,65 into a mutual fund until better technology or government incentives came along, in some areas, the government subsidies can make it worth your while. Also, keep in mind that in many areas, the net metering arrangements only deducts the power you've generated from your bill so you would want to size the array to meet your base usage in order to get the most from your investments. So meeting your actual needs would result in a loss on the return as there will be months where your usage is less than your average. In theory, if you put $7,208.69 into a mutual fund expected to return 4.4% per annum then you could withdraw enough to pay each month's power bill for 25 years at $0.0 a kwh and therefore be self sufficient through financial means. You would get more mileage focusing on heating and hot water as heating and hot water is 75% of a home's energy use and can be addressed with lower cost technologies like passive solar and solar thermal panels. You have to put it into perspective, it's an investment and you want a return that's competitive with your investment opportunities.
Q: Can solar panels be used in areas with high levels of heatwaves?
Yes, solar panels can be used in areas with high levels of heatwaves. In fact, solar panels can still generate electricity in extreme heat, although their efficiency may decrease slightly due to the temperature increase. However, it's worth noting that high temperatures can also lead to increased energy consumption for cooling, which may offset the benefits of solar energy to some extent. Nevertheless, solar panels remain a viable and sustainable solution for electricity generation in areas with high levels of heatwaves.
Q: Harbor Freight sells a 75 watt solar panel, a surge power inverter, and deep charge batteries. But no one there can tell me how to put it all together. I want the end output to be a simple power bar that I can plug my devices into. I live in an apartment so I can not wire it directly into the grid. Please only serious responses. Don't waste your time and mine.
I don't have direct experience with the Harbor Freight panels, but have heard that they are agressively rated - i.e., the three 5-watt panels are really 5-watt panels. The 80-watt panel is likely to be a serious panel, rated according to standard test conditions. It will also be more durable, and probably have a warranty of 20 years or more. There's really no comparison. If your goal is to experiment with solar electricity, then get the kit from Harbor Freight (or Northern Tool, or any of a handful of other places). If your goal is to save money, generally you will need a larger scale than 80 watts - several thousand watts being the norm. And the payback time will be measured in years.
Q: What's your opinion on solar power? More specifically, having panels installed on your roof to reduce your electric bill. I'm having a consultation tomorrow to get more details. I live in the SW, so it's always crazy sunny here. I don't know what the cost will be yet. Is it something you'd consider if the situation was right? If not, why?
Just had them installed on a development of 4 homes and they look goood! So far each user has free electricity during daytime for 3/4 of the year. If you live in a hot country - that's free A/C to keep you cool. The downside is that it is grid-tied so there is no storage, which means that if you use electricity to cook the evening meal - you don't get that free. What we advise to do instead is to make use of slow cookers that cook meals during the day - for FREE, and just serve it up in the evening as it keeps the heat. It would be more effective if you used storage radiators and heated hot water tanks for washing/bathing using it but this hasn't been added yet. It's free power all day - so what is there to complain about? The only catch I have found is that some power companies charge YOU if you export power to the grid - so just watch out for that, and design your system to avoid this if this applies, but most just don't pay anything - so you may as well use what you get.
