- Q: How do solar panels affect home insurance rates?
- Solar panels can potentially have a positive impact on home insurance rates. While the initial cost of installation may increase the overall value of a home, insurance companies often offer discounts or special policies for homes equipped with solar panels due to their reduced reliance on traditional energy sources and increased energy efficiency. However, it is recommended to consult with insurance providers to determine the specific impact on rates as it may vary depending on the location, type of system, and other factors.
- Q: About how much would it cost to purchase and install solar panels for the average American house so that the house can be off the power grid and use the same amount of electricity as it normally does?
- We are installing a 3.3 kWh system on a 2 story house. Really three story if you add in the basement. It will provide about 3/4 of the electric power they use per year. The cost of the complete system installed is in the $26,000 range. A 4.5 kWh system would wipe out their bill and would cost in the $34,000 range installed. But it had too many solar modules to fit on the roof. Now if you are wanting to go off grid in the average American home you would spend about $60,000 easy. Most American family's are very very waste full. Very few even have CFL lighting and leave every light in the house on. I have even known of some that will use a 60 watt night light when it is so easy to put in a CFL or a 4 watt night light. With 4 TV sets running in most homes at the same time a 200 watt stereo system for background noise.. Well we Americans have a long ways to go yet.
- Q: Are photovoltaic cells the same as solar panels?
- Solar panels are covered with photovoltaic cells that convert sunlight into electricity. So photovoltaic cells are part of solar panel. renewableenergyarticles.blogspot....
- Q: Ok so I am planning on buying a solar panel. I am doing it to possibly sell the energy that it stores. It is a 20 watt panel so I am just wondering if every week or month if I sold that energy that it stored would make me a good profit. I am not hoping for thousands of dollars a month..just like 00? The solar panel cost me $,00 so if so, how long do you think it would take to make good profit. Also, how much would I make every week or month?
- I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel /solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.
- Q: im trying to run my house with with solar panels, is it possible? if so please let me know how....i have a 6000 w inverter
- There are a variety of factors that come into play in order for you to calculate the answer. Additionally, there are a number of variables that can make the answer change over time. The number of solar panels you need to install to power your home will depend upon your electric power demands, the weather in your area, the angle of your roof, shade issues from nearby trees or buildings and the size of the cells. All of these factors are important and must be built into your calculations so that you can create the best solution for your home and your future needs.
- Q: i need to cut down on electricity bills, and so i was wondering if someone could give me step-by-step instructions, or websites that have step-by-step instructions on how to build an electricity generating solar panel.
- Build from scratch, sorry your way over your head. (mine too). There are lots of companies that will give quotes on doing what your looking for, but plan on spending 20 to 50K depending on where you live and what you need. I don't know about where you are, but My hydro bill is almost half delivery charges. Therefore I could cut back by 99% on the usage, and still only have my bill come down by less than 50%. I understand you desire to lower costs, but unless you do a big change(lots of outlay) your savings will be small. By all means shut off lights your not useing etc. there are other ways of lowering your household bills better way is solar heating. But this also depends on where you live. I'm building a solar collector for 2 houses , Contact me at and I'll pass on more info
- Q: I have seen quite a few different websites that talk about building your own solar panels for around $200. I wanted to know if anyone has had any experience with this before I decide to try it myself. It would be very helpful to know what I can expect from such an inexpensive setup; what kind of electronics or appliances would I be able to power. Realistically what can I expect from a $200 setup, and what would I need to power say a whole bedroom (clock, regular sized TV, PC, ext.).
- I okorder / You will also need to purchase at least 2 deep cycle 6 volt batteries and a 000 watt inverter. Depending on your usage you might need to add more batteries and or another panel to you system. Hope this helps.
- Q: how would you build a solar panel
- i'd go to the solar panel store and buy one. It would be /0 the cost of trying to build one in my HOME shop.
- Q: Do solar panels require a battery for storage?
- No, solar panels do not require a battery for storage.
