FAQ

To clean your solar panels, start by checking the manufacturer's instructions as some panels may have specific cleaning requirements. Generally, you can clean them by gently rinsing with water using a hose or a bucket and sponge. Avoid using abrasive materials or harsh chemicals that could damage the panels. If there's stubborn dirt or debris, you can use a mild soap solution with a soft brush to gently scrub the surface. Regularly cleaning your solar panels will help to maintain their efficiency and ensure optimal energy production.
I want to replace my electricity with solar and wind. I live just right outside the city, the roof about 000 square feet. How many windmills/solar panels would it take to get me off the power grid?
I live in the Southwest where the sun shines almost every day. I got a quote for Solar system to produce about enough to cover my annual usage. My annual average electrical usage costs about $2300, or about $90/MO. The system costs around $30,000 but I can get rebates and some of your tax dollars in subsidies to bring my cost down to under $20,000. I can borrow $20,000 for 3 years at 7% and pay $95/MO, so in 3 years I will have the system paid for. As you can see, I don't start Saving any money for a long time. Maybe the rates will go up in later years which will help, but My friends that have solar systems tell me things like controllers go bad over time and they cost like $3000. Will it ever pay for itself? Maybe. Please note. This still does not get me off the grid. This system will not support things like an electric stove, air conditioning, Pool pump running, etc. so I still need the grid for when these operate and my usage peaks. If I installed a system that would totally support everything 24/7 the cost would be astronomical. If you live in the east, midwest, or NW where you have cloudy days, your economic calculations will be much less favorable I would think, unless your power costs are much higher than mine..
I have a solar energy panel that works in every room except mine. I have those severely bright, energy efficient bulbs and it doesn't work at all.What do I do? Is the bulbs really causing this? Why?
It's giving off a good chunk of its energy as light in the range 800-00nm which the solar panel can efficiently harvest into electricity. As a lightbulb though, this energy is being wasted because you can't see light of those wavelengths!
The length of time it takes to recoup the investment in solar panels can vary depending on factors such as the cost of the system, available incentives, electricity usage, and local solar conditions. On average, it usually takes between 5 to 10 years to recover the initial investment through energy savings. However, with the declining costs of solar panels and the potential for government incentives, this payback period may be shorter in certain cases.
Can solar panels work in the shade?
The okorder / All solar panels sold by Energy Matters have bypass diodes, which send output from the remaining cells around that dead cell. However, you have lost the output of that cell, so the total panel voltage will drop by about 0.48 volts per cell. Most panels are in the 6 to 8 volt range, and most batteries need at least 3.5 volts to charge completely. So, if 2 or more cells are shaded, the output voltage of the panel may drop too low to charge the battery.
Hey i am going to build a scale model house and demonstrate how you would use solar panels to provide energy. I am thinking of buying some kit solar panels and wiring up some lights to show how they power the home. Also i might hook up a battery in the house to show how you can store the energy. I might also have a large battery hooked up outside the house to represent a power plant that could provide emergency power. Any ideas or comments would be great. Thanks
By gaps you could mean that it is expensive. Also, there is the debate over whether or not giving people incentives like tax breaks is a good idea Also, it takes a while to recoup the initial invesment in an array, although tax incentives would help and lastly, a solar array big enough to power the united states would have to be in an obnoxiously large area, alhough the ideal areas are already uninhabited because they are too hot.
i was reading the popular science magazine and i saw that they might make a Sun Powered it Absolutely NOT possible to make a car with a Solar Panel? I dont see any harm in making it..
Sailboats typically run on wind; hence, Sailboat. I haven't read your article on it though; but, I would think that the solar power would be for the battery powered stuff and possibly a little motor for it. For a car... There are competitions, right now for solar cars. Only they are very light and don't really go that fast. The panels tend to be large and weight a bit more than one would think. I don't understand why they can't simply make a car generate power simply by the rotation of the wheels itself. They could take a hybrid, take out the gasoline portion and it would simply recharge the batteries by the friction of the turning wheels.
Yes, solar panels can be used to power a farm. By harnessing the power of the sun, solar panels can generate electricity that can be used to run various farm operations such as irrigation systems, grain dryers, electric fencing, and even power agricultural machinery. This renewable energy source not only reduces reliance on fossil fuels but also helps farmers save on energy costs while promoting sustainability.
